Tucked into WikiLeaks’ analysis of a trove of documents allegedly from the Central Intelligence Agency is a stunning line: That the agency has looked into hacking cars, which WikiLeaks asserts could be use to carry out “nearly undetectable assassinations.”

In making its claim, WikiLeaks links to meeting notes from 2014 listing “potential mission areas” for the CIA’s Embedded Devices Branch, which includes “Vehicle Systems” and “QNX.” The leaked documents, which The Washington Post could not independently verify and the CIA has declined to confirm, do not appear to suggest the vehicles be used for assassinations, and even WikiLeaks admits “the purpose of such control is not specified.”

The fear that your car can be hacked and made to crash is not new, and it’s not completely unfounded. Concerns about automotive cyber security have been raised since automakers began outfitting cars and trucks with computer-controlled systems.

Those concerns have been compounded in recent years as an increasing number of cars come equipped with connections, including satellite, Bluetooth and Internet, that experts say make them more vulnerable to hackers who can then gain access to the computerized systems without ever stepping foot near the actual vehicle.

Here is what we know about hacking into and remotely controlling cars:

Vehicles have been hacked before 

In 2015, security researchers Charlie Miller and Chris Valasek hacked into a 2014 Jeep Cherokee and managed to “turn the steering wheel, briefly disable the brakes and shut down the engine,” the Post’s Craig Timberg reported. The pair found they could also access thousands of other vehicles that used a wireless entertainment and navigation system called Uconnect, which was common to Dodge, Jeep and Chrysler vehicles. The hack prompted Fiat Chrysler to recall 1.4 million vehicles.

“It doesn’t appear that any manufacturers currently have detection/prevention methods for such attacks,” Valasek said via email Tuesday. “Remember, Charlie and I did all this research in our spare time with limited resources. ”

The Miller and Valasek hack is widely reported, but it wasn’t the first or even most recent successful security breach. Researchers from the University of Washington and the University of California at San Diego published papers in 2010 and 2011 showing that vehicles could be compromised when hackers gain access, either in person or remotely.

Last year, researchers in Germany released a study showing they could unlock and start 24 different vehicles with wireless key fobs by taking control of the device remotely and amplifying its signal, Wired magazine reported. While the wireless key fob was still on the kitchen counter, hackers could be driving off with the car, researchers claimed.

Yoni Heilbronn, the vice president of marketing at Argus Cyber Security, an automotive security company, said: “The equation is very simple. If it’s a computer and it connects to the outside world, then it is hackable.”

Hackers could crash your car, but it’s unlikely 

Perhaps the greatest car-hacking fear is the idea that someone could take control of your vehicle and drive it over a bridge or into a brick wall.

The WikiLeaks release even renewed suspicions about the death of journalist Michael Hastings, who was killed in a single-car accident in Los Angeles in 2013.

“You could envision doing all sorts of things, such as waiting until the car is going above a particular speed limit and then apply one of the brakes or steer [the wheel] in cars for which you can control the steering,” said Stephen Checkoway, an assistant computer science professor at the University of Illinois at Chicago.

That fear is not without merit. As Miller and Valasek demonstrated, hackers have compromised some of the vehicle’s most critical functions and safety features before.

But those hacks require time and technical know-how to execute, making an attack something a run-of-the-mill criminal is unlikely to carry out, said Sam Lauzon, a researcher and developer at the University of Michigan Transportation Research Institute. What’s more, automakers are increasingly isolating the computers that control the vehicle’s most sensitive systems, meaning they cannot be breached even if hackers tap into other technologies, such as the entertainment system, he said.

“The likelihood of someone driving you off the road while you’re driving down the freeway is very slim,” Lauzon said. “Very slim.”

The WikiLeaks CIA documents did not appear to offer details on how the agency intended to hack into vehicles.

Your entertainment system is most vulnerable

Also listed in the WikiLeaks document of “possible mission areas” is QNX, a popular operating system for in-car entertainment and navigation technologies. Since 2010, QNX has been owned by Research in Motion, the company behind BlackBerry. The system has been used in more than 50 million vehicles that range from Audi to Ford to Maserati, according to the company.

Lauzon speculates that hacking the operating system could allow the CIA to track a vehicle’s movements, listen to conversations, or monitor other data that passes through the system.

The entertainment system is typically one of the most vulnerable to attack because it’s so highly connected to the outside world, both Lauzon and Heilbronn said. Connections to cellular networks, Bluetooth, WiFi, etc. often come through the system, allowing you to play music, take phone calls, look up directions or connect to other applications.

It’s hard to tell when a vehicle has been hacked 

The “nearly undetectable” assertion in the WikiLeaks claim likely stems from the fact that it’s difficult to determine when a car has been hacked, experts say.

“Today, manufacturers really have no idea what’s going on,” Heilbronn said. “They have no idea if it’s been hacked or not.”

There is currently no mechanism to alert manufacturers when a car is behaving erratically or appears to otherwise be compromised, Lauzon said. But technology companies and automakers alike have such technology under development.

“I haven’t seen one fitted on a vehicle at assembly time, but it’s something they’re looking into the feasibility of,” Lauzon said.

Automakers are aware of the problem

Today, Miller and Valasek work at ride-hailing company Uber. Auto manufacturers and transportation companies have scooped up a number of cyber experts in recent years, part of a concerted effort in the industry to build products with stronger security features.

Carlos Ghosn, the head of an alliance that includes Nissan, Mitsubishi and Renault, told a crowd in Washington last week that the employees building the alliance’s self-driving and connected car technologies are “surrounded by cybersecurity specialists who spend their time analyzing what could go wrong.”

“We take it very seriously because we know the end ticket to this technology is making sure that we’re going to reassure the regulator that you have a sufficient level of cybersecurity,” he said.

One of the challenges nagging automakers is how to update security software once it is installed in the vehicle. Cyber threats are always changing and upgrading a car’s security software through downloads — much as you would update the software on a smartphone — has only recently become feasible.

In 2015, auto industry players created the Automotive Information Sharing and Analysis Center to swap information about cyber security threats and how to combat them. Then last October, the National Highway Traffic Safety Administration published a cyber security “best practices” guide for automakers with suggestions for building more secure vehicles.

Computers in cars are actually a really good thing

Before you rush out to buy a dated vehicle to avoid the latest technology, it’s worth noting the benefits of driving computers on wheels.

Many modern safety features depend on computers and software to function, including anti-lock brakes, lane-assist technology and automatic crash notification. They also help under the hood to make the engine more energy efficient and provide conveniences, such as the ability to make phone calls with both hands on the wheel, Checkoway said.

“That they have enable new attacks is worrying, but on balance computers have improved safety,” he said.

What you can do about cyber threats

The short answer is not much.

As Heilbronn points out, car security is not like picking out Norton or McAfee anti-virus software for your laptop. Automakers have to build cybersecurity protections and software into the vehicle before it ever hits the road, and continue to update those programs as new threats emerge, he said.

“Today, the average customer doesn’t have any knowledge as to what should be installed,” Heilbronn said.

Lauzon does have one small piece of advice: avoid installing your own onboard diagnostics, or OBDII, devices, which can monitor a car’s performance, provide Internet connections and other features. These devices can communicate with the vehicle’s internal systems but may rely on insecure wireless connections, he said.

THE BIG IDEA: 

After appearing to project some ambivalence earlier in the day, President Trump came out strongly last night for the faltering House Republican plan to replace Obamacare. He told the group of about 20 lawmakers who will be charged with whipping up support for the legislation that he wants the Paul Ryan bill to be approved largely intact. He said he plans to become personally involved in persuading wavering lawmakers. And he warned that Republicans will suffer badly in the midterms if they fail to deliver on their campaign promises to get rid of the Affordable Care Act. One member who was in the private meeting told CNN that he even spoke of an electoral “bloodbath.”

Offering a taste of what’s to come, POTUS took to Twitter a few hours later to nudge Rand Paul, a 2016 rival for the GOP nomination who is now a potentially pivotal vote in the Senate:

I feel sure that my friend @RandPaul will come along with the new and great health care program because he knows Obamacare is a disaster!

— Donald J. Trump (@realDonaldTrump) March 8, 2017

The Kentucky senator described the draft language, which will be marked up in committee hearings today, as “Obamacare Lite” and pronounced it “dead on arrival.”

The House leadership Obamacare Lite plan has many problems. We should be stopping mandates, taxes and entitlements not keeping them.

— Senator Rand Paul (@RandPaul) March 7, 2017

The president is also trying to use carrots, not just sticks, stepping up outreach to other 2016 foes. Tonight he’s having dinner with Ted Cruz. Yesterday he lunched with Lindsey Graham. The South Carolina senator, as a gesture of goodwill, gave the president his new cell phone number. This is notable because, during a 2015 rally, Trump read Graham’s old number aloud to a crowd and asked people to call him.

Trump has negotiated big deals, but he’s never done anything quite like this. There will be a steep learning curve. “Following late-afternoon votes Tuesday, several Republican senators privately groused that they felt rushed by their GOP colleagues in the House and by Trump, who they said does not fully grasp the Senate’s slower pace or its concerns,” Mike DeBonis, Robert Costa and David Weigel report. “The senators also expressed skepticism that key White House officials with deep ties to Congress’s conservative wing would eventually be able to lock up the votes for the current plan. Instead, they said there is confusion over who is managing the process and which administration figures, if any, have power to sway Trump on the issue.”

Just how much political capital Trump is willing to spend is an open question that could determine the fate of the 2010 law. Will he keep his tweets gentle like the one aimed at Paul last night or will they take on a harder, more personal edge? You could imagine him lashing out at leaders of Freedom Caucus on a Saturday morning, for instance, blaming them for the failure of his agenda. Perhaps the fear of drawing his ire – a credible threat based on his track record – will get some members off of the fence. There are other ways he could use his power: Would he have rallies in the states or districts of wavering lawmakers? Will his new outside group run ads promoting the bill or criticizing those who oppose him?

There’s an emerging sense among some in Trump World that repeal and replace will not happen without muscular leadership from the president, but there’s also a growing recognition of the political risks that come with wading in deeply. Four are top of mind:

1. RUNNING AFOUL OF CONSERVATIVES IN THE GOP CIVIL WAR:

The battle lines are drawn. The U.S. Chamber of Commerce and Wall Street Journal editorial board support the Ryan plan. The Koch network (led by Americans for Prosperity), the Club for Growth, FreedomWorks, Heritage Action and Breitbart vocally opposed it. People on the right have dubbed the plan “Obamacare Lite” or “RyanCare.”

Many of these groups opposing the draft bill have never viewed Trump as an authentic movement conservative. If they see him as joining forces with the establishment to ram through something that is tantamount to a new government entitlement, it will only bolster their skepticism. It’s not out of the question that Trump will have a primary challenger from his right to contend with in three years, and this could be a data point.

2. BACKLASH FROM SENIORS:

Seniors constitute Trump’s core base of support. Exit polls showed that the septuagenarian really ran up the score with older people vis-à-vis Mitt Romney, and this might have made the difference in several states.

The draft legislation Trump embraces would undo a rule from the ACA that allows insurers to charge their oldest customers no more than three times what they charge their youngest and healthiest ones. Insurers could now charge five times as much.

AARP has already begun mobilizing its members on this point. David Certner, the senior lobby’s legislative counsel, said the group is particularly concerned about the effect on Americans ages 50 to 64 if that age-charge differential is to increase. Low-income Americans in that older group would “get hammered,” he said, per Amy Goldstein and Juliet Eilperin.

Expect to see hundreds of anecdotes like this one over the coming months: “Martha Brawley of Monroe, N.C., said she voted for President Trump in the hope he could make insurance more affordable. But on Tuesday, Ms. Brawley, 55, was feeling increasingly nervous based on what she had heard about the new plan from television news reports,” the New York Times reports. “She pays about $260 per month for a Blue Cross plan and receives a subsidy of $724 per month to cover the rest of her premium. Under the House plan, she would receive $3,500 a year in tax credits — $5,188 less than she gets under the Affordable Care Act. ‘I’m scared, I’ll tell you that right now, to think about not having insurance at my age,’ said Ms. Brawley, who underwent a liver biopsy on Monday after her doctor found that she has an autoimmune liver disease. ‘If I didn’t have insurance, these doctors wouldn’t see me.’”

3. THE 2020 FACTOR:

Timing is everything in politics. If the disastrous rollout of healthcare.gov happened in Oct. 2012, instead of Oct. 2013, Obama very well might have lost reelection. Recognizing the risks of implementation, they postponed a lot of deadlines until after elections.

The most striking thing about studying the draft House bills is how much stuff comes due in 2020, when Trump has already announced he will be running for reelection and Republicans will be fighting to preserve their narrow majority in the Senate.

“The changes to the Medicaid expansion and the subsidy system would take hold at the beginning of 2020,” Greg Sargent observes. “Democratic candidates will be able to blast Republicans who voted for the GOP replacement, on the grounds that it is resulting in their states’ residents getting tossed off of coverage, while vowing to replace the spending. Some GOP senators up for reelection in 2020 in swing states also happen to represent states that already opted into the Medicaid expansion. That includes Joni Ernst in Iowa and Cory Gardner in Colorado. There’s also Thom Tillis in North Carolina (which didn’t expand Medicaid but could lose a lot in subsidies). ‘The Republican health-care plan as it stands today would certainly endanger some Republican incumbents up in 2020,’ said Jennifer Duffy, who tracks Senate races at the Cook Political Report. Some of these senators got elected by campaigning against the ACA’s rollout problems amid the shriveled midterm electorate of 2014 and will now face reelection in a presidential year, as repeal’s impact takes hold.”

4. HE FULLY OWNS FAILURE:

The more aggressively he sells the bill, the more he will be identified with its collapse if things don’t work out.

The margin for error is small: They can afford to lose 21 Republicans in the House and just two in the Senate.  The House Freedom Caucus has about 30 members. Several of them held a press conference outside the Capitol to say they’d never vote for the measure as it stands now. They ideally want straight repeal with nothing else, which is just never going to happen. In addition to Paul and Cruz, Sen. Mike Lee (R-Utah) opposed the House draft yesterday. If the three of them voted no, the measure would fail.

But, but, but: Every concession that’s made to win over the Freedom Caucus and that trio in the Senate makes it harder to lock down the votes of someone like Susan Collins or Rob Portman. The Ohio senator who was one of four Republicans to declare this week that he’ll oppose any plan that hurts lower-income folks who benefited from expanding Medicaid under the law. The others are Shelley Moore Capito (W.Va.), Cory Gardner (Colo.) and Lisa Murkowski (Alaska).

Mitch McConnell said yesterday that the Senate will pass a repeal bill before Easter recess: “Senior GOP sources said the leadership team will employ an ‘arm-breaking’ whip strategy to get the required 50 votes,” Politico’s Burgess Everett reports.

This “arm-breaking” approach could backfire, however. One Republican senator said on background last night that several senators are asking their leadership to “take it easy” in terms of the timeline, allowing space to debate and analyze the proposal with a “clear understanding of the costs involved,” per DeBonis, Costa and Weigel’s story on the state of play. “If that takes months or a year, so be it,” the senator said. A second GOP senator said the party was making a “mistake” in its rollout by taking “too much ownership” of health care after years in which Democrats were identified with Obamacare.

KEY POINT: MIKE PENCE WILL NEED TO BE THE CLOSER.

The vice president will be crucial to winning over recalcitrant House Republicans he once served with. He has credibility because he voted against Medicare Part D when the Bush White House was heavily pressuring Republicans to fall in line.

Pence, an Indiana talk radio host before getting elected to Congress, has several interviews scheduled this afternoon to sell what’s been branded as The American Health Care Act. He’ll talk to Sean Hannity for his radio show and then sit-down with local TV affiliates from Virginia, Michigan, Wisconsin, Ohio, Pennsylvania, North Carolina and Florida.

But the VP is best at the inside game, especially compared to Trump, which is why the most important thing on Pence’s calendar today is a 7 p.m. “legislative affairs dinner” at the Naval Observatory to schmooze lawmakers. Dave Weigel relays a telling anecdote from the Capitol yesterday: “The House Freedom Caucus was ready for the spotlight. Dozens of reporters and cameramen had set up at the House Triangle. Some cable networks were taking their news conference live. But a few reporters were being held inside the Capitol by security guards because Pence was wrapping a visit to the Hill, talking to Freedom Caucus members. When the vice president left, some of the conservative rebellion’s leaders were taking a more measured — if still skeptical – stance.”

As Trump embraced the specific bill, his top aides clarified that he is very open to changes and amendments to make it better. In his conversations with members yesterday, Pence stressed that the Ryan plan is “the framework for reform.” OMB director Mick Mulvaney, a member of the Freedom Caucus until just a few weeks ago, carried a similar message when he went to the Hill to reassure the right flank of the conference that the president is open to amendments. “This is a work in progress and continues to be so,” HHS secretary Tom Price said on Fox News last night. “Let me make clear to people that this single bill is not the entire plan. »
 

FIVE MORE OBAMACARE STORIES FROM OUR TEAM:

— “Obamacare repeal guts crucial public health funds,” by Lena H. Sun: “The Republican health-care bill would eliminate funds for fundamental public health programs, including for the prevention of bioterrorism and disease outbreaks, as well as money to provide immunizations and heart-disease screenings. As part of the ACA, the Prevention and Public Health Fund provides almost $1 billion annually to the Centers for Disease Control and Prevention. Since 2010, the fund has been an increasingly important source of money for core CDC programs, today accounting for about 12 percent of the CDC’s total budget. The GOP bill would eliminate the Prevention and Public Health Fund starting in October of next year. No clear replacement has been proposed. Cuts in those funds, combined with potential federal budget cuts at the CDC and other health agencies, ‘could amount to a catastrophic year for public health funding,’ according to a statement from the Association of State and Territorial Health Officials.”

— “Here are five ways the GOP proposal would change the tax system,” via WaPo budget reporter Kelsey Snell: 1. This is a major tax cut for the rich. 2. Lower-income workers are going to feel the biggest squeeze. 3. There may be more tax changes to come. 4. All of these tax changes could create a big deficit headache. 5. Democrats and even some conservatives are skeptical the math will work out in Republicans’ favor.

— “Income separates the winners and losers in Republicans’ health-care plans,” by Amy Goldstein and Juliet Eilperin: “An analysis by SP Global predicts the legislation would lead to a loss of coverage for 2 million to 4 million of the roughly 16 million Americans who bought their own health plans through the ACA’s marketplaces or separately. More adults 35 and younger would gain coverage, while fewer adults 45 and older would be insured, according to the analysis. Specifically, the current subsidies take into account the cost of insurance in a given area, and they are linked to premiums for the next-to-lowest ‘silver’ health plan — the second rung among four ACA tiers that supply different levels of coverage. Under House Republicans’ plans, those tiers would disappear and the tax credits would no longer vary depending on geography. As a result, the largest credits, $4,000 for people 60 and older, would cover more than half the typical insurance premiums in New Mexico, for example, but less than a third of the cost in Wyoming.”

— Bigger picture — “The debate over the Affordable Care Act is really a debate over wealth redistribution,” by Karen Tumulty: “What makes the latest health-care battle different from past ones is that it is not about building a new government program. This time, the question is whether to abolish one … That means it is harder to gloss over a bedrock philosophical and ideological question that has always been in the background of any argument about the government’s role in health care: What is the minimum that society should provide for its poorest, most vulnerable citizens, and how much should be taken from the rich and powerful to do it? ‘Even though it is a technical discussion, it’s a really big value discussion,’ said Robert Blendon, a professor of health policy and political analysis at Harvard University…

“There were many ways that Obamacare redistributed the burden of medical costs — from the sick to the healthy, with provisions such as the one denying insurers the ability to refuse coverage to people with preexisting conditions; from the old to the young, with a mandate that everyone have coverage or pay a penalty; from the rich to the poor, with an array of new taxes.”

— “The most popular (and unpopular) parts of House Republicans’ health-care plan,” by WaPo polling director Scott Clement: “The Republicans’ plan keeps several of the law’s most popular provisions, but also scales back or repeals several others that enjoy majority support. As widely expected, the law also repeals the individual mandate to buy insurance (or pay a fine), the least popular part of the ACA.”

• Popular parts the GOP plan keeps: “The House Republicans’ replacement plan preserves four parts of the ACA that at least 60 percent of adults favored keeping in a January Associated Press-NORC poll. The survey found 77 percent supported the ACA’s requirement that private insurance companies offer preventive health services at no out-of-pocket cost, while 60 percent supported requiring plans to cover the full cost of birth control. The plan also includes the signature ACA rule prohibiting insurance companies from denying coverage or charging more to people with preexisting medical conditions, which was supported by 69 percent. More than 70 percent supported allowing adult children up to age 26 to stay on their parents’ health plans, which the GOP plan keeps.”
• Popular parts the GOP plan changes: “A McClatchy-Marist poll last month found that 72 percent of adults said lawmakers should keep financial help for lower-income people; in November, a Kaiser Family Foundation poll found 80 percent favorably viewed the law’s subsidies for those with lower and middle incomes. Two-thirds of Americans (66 percent) in the AP-NORC poll supported expanding Medicaid to more low-income, uninsured adults … The bill would also cap the amount of federal Medicaid funding a state receives per person. … While this issue is fairly complex, a February Kaiser Family Foundation poll found roughly 32 percent of the public supported such a change, while 63 percent preferred maintaining federally guaranteed benefits.”

WHILE YOU WERE SLEEPING:

— Today is International Women’s Day and “A Day Without A Woman,” in which many plan to stay home as a form of protest. Several local schools are closed today, including in Alexandria and Prince George’s County. The Maryland district announced the closure last night after 1,700 teachers and 30 percent of the transportation staff asked for the day off. With those numbers, the system said, it could not transport students and provide proper learning environments. (Marty Weil)

— The state of Hawaii will ask a federal judge to block Trump’s revised executive order barring issuance of new visas to citizens of six Muslim-majority countries. The suit, which lawyers plan to file today, will be the first formal legal challenge to the second ban. (Matt Zapotosky)

— Nigeria advised its citizens against non-essential travel to the United States, warning that people have had their visas canceled and been denied entry without explanation. The Nigerians claim an American customs official told one guy that he didn’t “look like” a software engineer and demanded he prove expertise in his field. (CNN)

— Trump nominated Noel Francisco to be U.S. solicitor general. He comes from Jones Day and has been working on the re-launch of the travel ban. He once clerked for Antonin Scalia and has argued several times before the high court in private practice. Last year, he successfully represented former Virginia Gov. Bob McDonnell during his appeal to SCOTUS.

WHAT COULD POSSIBLY GO WRONG?

— The Trump administration, searching for money to build a border wall and fund a deportation force, is weighing significant cuts to the Coast Guard, TSA, FEMA and other federal agencies focused on national security threats. Dan Lamothe, Ashley Halsey III and Lisa Rein report: “The Coast Guard’s $9.1 billion budget in 2017 would be cut 14 percent to about $7.8 billion (under a working draft proposal), while the TSA and FEMA budgets would be reduced about 11 percent each to $4.5 billion and $3.6 billion, respectively. The plan puts the administration in the unusual position of trading spending on security programs for other security priorities at the southern border, raising questions among Republican lawmakers and homeland-security experts. Rep. Duncan Hunter (R-Calif.), who supported Trump’s presidential bid and oversees the House Transportation subcommittee on the Coast Guard and maritime transportation, questioned whether OMB officials are on the same page as the White House, citing the sea service’s roles in stopping illegal immigration and the flow of drugs into the country. »

WIKILEAKS STRIKES AGAIN:

— A vast portion of the CIA’s computer hacking arsenal appears to have been exposed by WikiLeaks, which posted thousands of files revealing highly-classified CIA hacking tools used to convert cellphones, televisions and other ordinary devices into implements of espionage. Greg Miller and Ellen Nakashima report: “The trove appeared to lay bare the design and capabilities of some of the U.S. intelligence community’s most closely guarded cyber weapons, a breach that will likely cause immediate damage to the CIA’s efforts to gather intelligence overseas and place new strain on the U.S. government’s relationship with Silicon Valley giants. … [Officials said] the breach could undermine the CIA’s ability to carry out key parts of its mission, from targeting the Islamic State and other terrorist networks to penetrating the computer defenses of sophisticated cyber adversaries.”

• “It looks like really the backbone of their network exploitation kit,” said one former hacker who worked for the NSA.
• « Any exposure of these tools is going to cause grave if not irreparable damage to the ability of our intelligence agencies to conduct our mission,” a former senior U.S. intelligence official said.

— There is no good rationale for this disclosure: WikiLeaks claimed to have gotten the files from a former CIA contractor and touted the trove as comparable in scale and significance to the NSA leaks exposed by Edward Snowden. « But while the Snowden files revealed massive surveillance programs that gathered data on millions of Americans, the CIA documents posted so far by WikiLeaks appear mainly to unmask hacking methods that many experts already assumed the agency had developed, » Greg and Ellen note.

— Meanwhile, Trump’s approach to WikiLeaks has taken a full 180 now that he is the one occupying the White House. Only a few months ago, he praised the organization during his rallies and once lauded it as a “treasure trove. » Jenna Johnson and Ashley Parker report: “Back then, Trump loved anything that made his rival Hillary Clinton look bad — even if the information had been hacked, stolen or leaked. But now that he is in the White House, Trump is having to confront the threat of hacking, along with leaks from within his own administration — and, suddenly, he is not a fan. Trump and his aides have angrily railed against leakers, threatening to find and prosecute them and urging congressional allies to investigate, while being uncharacteristically quiet when it comes to WikiLeaks. … The breach could pose a serious challenge for Trump, who has been feuding with the intelligence community over probes into alleged ties between his campaign and Russia. »

• Former Clinton campaign manager Robby Mook said he hopes Trump finally realizes that the hacking in the election is “an anti-American problem,” rather than a partisan one: “The problem at its core is that a country that our own Joint Chiefs of Staff said was our greatest enemy and greatest threat to our security stole information from one of our national political parties and used it against one of the candidates,” he said, referring to Russia. “Do I believe that this is going to come back to haunt the Republicans? Absolutely, I do.”
• Sean Spicer declined to comment on the latest WikiLeaks dump during his press briefing, saying that the issue “has not been fully evaluated.”
• John McCain said that, if the group “can hack the CIA, they can hack anybody,” and urged the White House to place more focus on the issue: “I’d like to see a greater emphasis, to tell you the truth. »

— The mole hunt has begun. Devlin Barrett reports: “In the wake of revelations from Army private Chelsea Manning and Edward Snowden, officials sought to tighten security procedures, and federal agents came under greater pressure to find and prevent secrets from spilling out of the government. But cracks keep appearing in the system. Now, U.S. intelligence agencies are [again] rushing …  to determine whether they again have suffered an embarrassing compromise at the hands of one of their own. … Once investigators verify the accuracy of the WikiLeaks documents, a key question to answer is who had access to the information, according to veterans of past leak probes.”

— Trump’s then-campaign manager Corey Lewandowski personally approved foreign policy adviser Carter Page’s now-infamous trip to Moscow last summer on the condition that he would “not be an official representative” of the Trump campaign. Politico reports: “A few weeks before he traveled to Moscow to give a July 7 speech, Page asked J.D. Gordon, his supervisor on the campaign’s National Security Advisory Committee, for permission to make the trip, and Gordon strongly advised against it. … Page then emailed Lewandowski and spokeswoman Hope Hicks asking for formal approval, and was told by Lewandowski that he could make the trip, but not as an official representative of the campaign, the former campaign adviser said. The trip is now a focus of congressional and FBI investigations into Russian influence in the 2016 presidential election.” Lewandowski said he did not recall the email exchange but “did not deny” that it occurred. “Is it possible that he emailed me asking if he could go to Russia as a private citizen?” Lewandowski said Tuesday. “I don’t remember that, but I probably got 1,000 emails a day at that time … And I wouldn’t necessarily remember if I had a one-word response to him saying he could do something as a private citizen.”

— Trump’s nominee for deputy attorney general declined to endorse Democratic calls for a special prosecutor to investigate Russia’s election interference during his confirmation hearing. Matt Zapotosky, Sari Horwitz and Sean Sullivan report: “Under insistent questioning from Democrats, deputy attorney general nominee Rod J. Rosenstein refused to commit Tuesday to appoint a special counsel to oversee investigations of Russian meddling … though he stressed that he did not yet know the facts of the matter. At a tense Senate Judiciary Committee confirmation hearing that lasted more than 3 1/2 hours, Rosenstein said that he was ‘not aware’ of any reason he would not be able to supervise such probes. “You view it as an issue of principle, that I need to commit to appoint a special counsel in a matter that I don’t even know if it’s being investigated,” he told Sen. Richard Blumenthal (D-Conn.), who had vowed to try to block his nomination should he not make such a commitment. “And I view it as an issue of principle that as a nominee for deputy attorney general, I should not be promising to take action on a particular case.”

— Al Franken says he has concluded that Attorney General Jeff Sessions definitely committed perjury during his confirmation hearing when he failed to disclose his meetings with the Russian ambassador. « It’s hard to come to any other conclusion than he just perjured himself, » the Minnesota Democrat said on CNN, telling host Jake Tapper that Sessions should come before the Senate Judiciary Committee again to explain himself.

— Christopher Steele, the former British spy who authored the controversial dossier on Trump, which was widely circulated and eventually sent him and his family into hiding, has reemerged. London journalists said he was spotted outside his company’s building on Tuesday, appearing relaxed – albeit tight-lipped — about his recent whereabouts. « I’m now going to be focusing my efforts on supporting the broader interests of our company here,” Steele told reporters. “I’d like to say a warm thank you to everyone who sent me kind messages and support over the last few weeks,” he added.

— Before spending $30 million to help Trump, the NRA sent a delegation to meet with Putin’s deputy in Moscow. The Daily Beast’s Tim Mak reports: “In March 2014, the U.S. government sanctioned Dmitry Rogozin—a hardline deputy to [Putin], the head of Russia’s defense industry and longtime opponent of American power— in retaliation for the invasion of Crimea and Eastern Ukraine. Eighteen months later, the [NRA], Trump’s most powerful outside ally during the 2016 election, sent a delegation to Moscow that met with him. David Keene, the former NRA president and current board member who was on the Moscow trip, insisted the meeting …. had nothing whatsoever to do with geopolitics. But Rogozin is no ordinary Russian official, and his title extends far beyond being merely the chairman of a shooting club. His portfolio as deputy prime minister of Russia includes the defense industry. One issue where Rogozin seems particularly interested is cyberwarfare, which he has heralded for its ‘first strike’ capability.”

WIRETAPPING FALLOUT:

— “The rapport between [Barack Obama and Trump] is unraveling, with the president convinced that Mr. Obama is undermining his nascent administration and the former president furious over Trump tweets accusing him of illegal wiretapping,” the Wall Street Journal’s Carol E. Lee and Peter Nicholas report: “The budding feud between two men who share the unique bond of membership in the commander-in-chiefs’ club is a fresh distraction in a Trump presidency that has been struggling to enact its agenda. The rift also is distancing Mr. Trump from a former two-term president who had offered to give private advice and counsel as the onetime businessman settles into his first job in public office.”

— The New York Times’ Glenn Thrush and Maggie Haberman report on the turmoil Trump’s tweets often create among his closest circles: “[His Saturday tweet, for example], led to a succession of frantic staff conference calls, including one consultation with the White House counsel, Donald F. McGahn II, as staff members grasped the reality that the president had opened an attack on his predecessor. Mr. Trump, advisers said, was in high spirits after he fired off the posts. But by midafternoon, after returning from golf, he appeared to realize he had gone too far, although he still believed Mr. Obama had wiretapped him.” He reportedly asked staff about hiring someone on the outside to try corroborating his claims.

— House Intelligence Committee Chairman Devin Nunes (R-Calif.) said he has not seen any evidence supporting Trump’s claim that he had been “wiretapped” by the Obama administration, but said his committee would “look into it anyway.” Karoun Demirjian reports: “The bigger question that needs to be answered is whether or not Mr. Trump or any of his associates were in fact targeted by any of the intelligence agencies or law enforcement authorities,” Nunes told reporters Tuesday. “At this point we don’t have any evidence of that,” Nunes said. “But we also don’t have any evidence of many people who have been named in multiple news stories that supposedly are under some type of investigation.”

Ranking committee Democrat Adam B. Schiff (Calif.) also told reporters that he was “happy” to look into Trump’s allegations – but warned that, if proven false, could pose much bigger problems for the new commander-in-chief. “If a sitting U.S. president alleging that his predecessor engaged in the most unscrupulous and unlawful conduct … that is also a scandal, if those allegations prove to be false,” Schiff said. “And we should be able to determine in fairly short order whether this accusation was true or false.” 

CONFLICTS OF INTEREST:

— “‘Big Candy’ is lobbying the Trump administration. It’s also holding events at Trump hotels,” by Amy Brittain and Jonathan O’Connell: “As U.S. candymakers descended on South Florida for their industry conference this week, they were scheduled to plot lobbying strategy in the ‘Ivanka Trump ballroom.’ A dessert networking event was planned for the ‘Donald J. Trump grand patio.’ Between meetings, attendees were eligible to enjoy outings on a Trump-owned golf course and massages at a Trump spa. The National Confectioners Association is doing a lot of business with President Trump’s company. In addition to this week’s gathering of 600 attendees … the group has booked two upcoming meetings, in September and again in 2018, at the Trump International Hotel down the street from the White House…

“At the same time, the organization, representing candy titans Hershey, Mars and Jelly Belly, among other companies, is optimistic about scoring big, early policy wins from the Trump administration. Among the industry’s priorities: a long-sought rollback of government sugar subsidies that candy firms say drive up the costs of making their products. The group said it booked the venues in 2014 and 2015, long before Trump won the presidency. But the arrangement illustrates a repercussion of Trump’s decision to retain ownership of his business during his time in the White House — that he can become financially intertwined with a special interest that is simultaneously seeking to influence policy decisions by his administration.”

WEST WING INTRIGUE:

— “White House official Boris Epshteyn, a combative Trump loyalist tasked with plugging the president’s message on television, threatened earlier this year to pull all West Wing officials from appearing on Fox News after a tense appearance on anchor Bill Hemmer’s show,” Politico’s Annie Karni reports: “Epshteyn … got in a yelling match with a Fox News booker after Hemmer pressed him for details of [Trump’s] controversial executive order cracking down on immigration from Muslim-majority countries — a topic he was not expecting to be grilled on. ‘Am I someone you want to make angry?’ Epshteyn told the booker, the sources said. When he threatened to pull White House officials from the network, the fed-up booker had had enough. ‘Go right ahead,’ the booker fired back, the sources said. Epshteyn’s rise to a position of prominence in the Trump White House reveals how the president has rewarded his loyalists. But Epshteyn … has added to the impression of an antagonistic White House by throwing his weight around in a manner that has further strained the relationship between the administration and the television networks.”

— Two front-runners have emerged to be Trump’s next Navy secretary after his previous pick, Philip Bilden, pulled out due to investment conflicts. The Wall Street Journal’s Gordon Lubold reports: “The White House is considering Richard V. Spencer, an investment banker with extensive business experience and ties to the Pentagon, and Randy Forbes, a former Virginia congressman and onetime chairman of an important naval subcommittee, to head the Navy, the officials said. Defense Secretary Jim Mattis and other senior officials at the Pentagon favor Mr. Spencer, a former Marine aviator with extensive investment and business experience. Vice President Mike Pence backs Mr. Forbes, a Virginia Republican who lost a primary bid for his re-election campaign last year.

— National security adviser H.R. McMaster has invited top council staff back into the Oval Office for calls between Trump and foreign leaders — reversing a decision by his ousted predecessor Michael Flynn to exile senior directors to the Situation Room during such conversations because of fears they’d get leaked.

THE WORLD IS ON FIRE:

— Insurgents struck Afghanistan’s largest military hospital, leaving at least four dead and at least 60 more injured after a suicide bomber and gunmen attacked the medical compound. ISIS has claimed responsibility. Sayed Salahuddin and Pamela Constable report: “Officials said at least four gunmen stormed the Sardar Dawood medical complex, located near the U.S. embassy and government buildings in the heart of the city. One security official said the attackers were disguised in white doctors’ uniforms. The battle stretched on four hours through much of the day with the attackers holed up in the upper floors of the hospital where they were engaged by special forces. … The double assault followed a familiar pattern by Taliban insurgents in which an official target is bombed at its entrance and armed fighters quickly follow.”

— China warned of “consequences” for South Korea and the U.S. over the newly-deployed U.S. antimissile system known as THAAD, further raising tensions in the region. Emily Rauhala reports: “The stern words came a day after North Korea launched four missiles that landed off the Japanese coast — an exercise, the North Korean government said, designed to practice for an attack on U.S. military bases in Japan. While American and South Korean officials say the Kim regime’s continued launches demonstrate why the new antimissile system is necessary, Beijing sees the system as a threat to the Chinese military and evidence of U.S. ‘meddling’ in East Asian Affairs. »

— Secretary of State Rex Tillerson is going on a trip to China, Japan and South Korea next week. “But he is traveling without the usual symbolism of the big blue and white ‘United States of America’ plane past secretaries of state have routinely used, and without the usual U.S. press corps,” Anne Gearan and Carol Morello report. “The State Department has said only that a smaller plane is more convenient and reliable, and that there is not room to bring reporters.” That’s not even good spin…

WAPO HIGHLIGHTS:

— THE BEST NON-POLITICS STORY YOU’LL READ ALL DAY: “Is Richard Simmons missing? Or is he just dearly missed?” by Dan Zak: “On Feb. 15, 2014, the flamboyant fitness guru did not show up to teach his regular $12 exercise class at his studio, which was called Slimmons. He cut off contact with friends and hasn’t been seen in public since. One of his regular students was a filmmaker-writer named Dan Taberski, who last month launched a podcast called ‘Missing Richard Simmons.’ ‘I think he’s important,’ Taberski says in Episode 1, justifying his loving invasion of Simmons’s privacy. Richard Simmons is many things: manic, brilliant, troubled, tough, hilarious, ridiculous. But important too? …. Simmons is a gaudy rhinestone embedded in American culture: a true original whose commercial sorcery summoned the forces of positive thinking and negative self-imaging. He cast his spell using old-fashioned vaudeville techniques that he must’ve inherited. He also helped the world gain something. ‘…God could have made you a butterfly that lasts three months, but he made you a human being,’ [he said on CNN in 2014]. Six weeks later, poof.”

But in recent weeks, riders have been asking him — two, three, sometimes as many as seven times a day — to bring them to the end of Roxham Road. He is carrying them on the last leg of their journey out of the United States. ‘You wonder what’s going through their heads, you know?’ he said. … Many of his passengers have been families, with parents carrying young children and whatever possessions they could take with them. Some were migrants from Yemen and Turkey.

VIDEOS OF THE DAY:

See why Anderson Cooper has muted Trump on Twitter:

The lights illuminating the Statue of Liberty turned off for more than an hour last night:

Margarita Zavala, a leading presidential hopeful in Mexico and former first lady, spoke with The Post about why her country will never pay for the wall. Read her op-ed. Watch some highlights: 

The anti-secrecy organization WikiLeaks said Tuesday that it has obtained a vast portion of the CIA’s computer hacking arsenal, and began posting the files online in a breach that may expose some of the U.S. intelligence community’s most closely guarded cyber weapons.

WikiLeaks touted its trove as exceeding in scale and significance the massive collection of National Security Agency documents exposed by former U.S. intelligence contractor Edward Snowden.

A statement from WikiLeaks indicated that it planned to post nearly 9,000 files describing code developed in secret by the CIA to steal data from targets overseas and turn ordinary devices including cellphones, computers and even television sets into surveillance tools.

The authenticity of the trove could not immediately be determined. A CIA spokesman would say only that “we do not comment on the authenticity or content of purported intelligence documents.” But current and former U.S. officials said that details contained in the documents suggest that they are legitimate.

Such a breach of U.S. intelligence capabilities, and the potential fallout it might cause among U.S. allies, could pose a significant challenge to President Trump, who in the past has praised WikiLeaks and disparaged the CIA.

WikiLeaks indicated that it obtained the files from a current or former CIA contractor, saying that “the archive appears to have been circulated among former U.S. government hackers and contractors in an unauthorized manner, one of whom has provided WikiLeaks with portions of the archive.”

“At first glance,” the data release “is probably legitimate or contains a lot of legitimate stuff, which means somebody managed to extract a lot of data from a classified CIA system and is willing to let the world know that,” said Nicholas Weaver, a computer security researcher at the University of California at Berkeley.

Faking a large quantity of data is difficult, but not impossible, he noted. Weaver said he knows of one case of WikiLeaks deliberately neglecting to include a document in a data release and one case of WikiLeaks deliberately mislabeling stolen data, “but no cases yet of deliberately fraudulent information.”

U.S. officials also allege WikiLeaks has ties to Russian intelligence agencies. The website posted thousands of emails stolen from Democratic Party computer networks during the 2016 presidential campaign, files that U.S. intelligence agencies concluded were obtained and turned over to WikiLeaks as part of a cyber campaign orchestrated by the Kremlin.

[WikiLeaks releases thousands of documents about Clinton and internal deliberations]

U.S. intelligence officials appeared to have been caught off guard by Tuesday’s disclosure. Senior White House and Pentagon officials had not been aware of the breach.

One U.S. official said investigators were only beginning to look at the files being posted online and declined to say whether the CIA had anticipated the leak or warned other agencies.

“We’ll see what it is whenever they release the codes,” said the official, who spoke on the condition of anonymity, citing the sensitivity of the matter.

WikiLeaks said the trove comprised tools — including malware, viruses, trojans and weaponized “zero day” exploits — developed by a CIA entity known as the Engineering Development Group, part of a sprawling cyber directorate created in recent years as the agency shifted resources and attention to online espionage.

The digital files are designed to exploit vulnerabilities in consumer devices including Apple’s iPhone, Google’s Android software and Samsung television sets, according to WikiLeaks, which labeled the trove “Year Zero.”

In its news release, WikiLeaks said the files enable the agency to bypass popular encryption-enabled applications — including WhatsApp, Signal and Telegram — used by millions of people to safeguard their communications.

But experts said that rather than defeating the encryption of those applications, the CIA’s methods rely on exploiting vulnerabilities in the devices on which they are installed, a method referred to as “hacking the endpoint.”

WikiLeaks said the files were created between 2013 and 2016, and that it would only publish a portion of the archive — redacting some sensitive samples of code — “until a consensus emerges on the technical and political nature of the CIA’s program.”

The data release alarmed cybersecurity experts.

“This is explosive,” said Jake Williams, founder of Rendition Infosec, a cybersecurity firm. The material highlights specific anti-virus products that can be defeated, going further than a release of NSA hacking tools last year, he said. The CIA hackers, according to WikiLeaks, even “discussed what the NSA’s . . . hackers did wrong and how the CIA’s malware makers could avoid similar exposure.”

Hackers who worked at the NSA’s Tailored Access Operations unit said the CIA’s library of tools looked comparable. The implants, which are back doors, or software that enables a hacker to get into a computer, are “very, very complex” and “at least on par with the NSA,” said one former TAO hacker who spoke on the condition that his name not be used.

Beyond hacking weapons, the files also purportedly reveal information about the organization of the CIA’s cyber directorate, with an organization chart and files that indicate that the agency uses the U.S. consulate in Frankfurt, Germany, as a hub of digital operations in Europe, the Middle East and Africa.

Though primarily thought of as an agency that recruits spies, the CIA has taken on a larger role in electronic espionage over the past decade. In a measure of that shifting focus, the agency created a special office, the Directorate of Digital Innovation, as part of a broad reorganization in 2015, effectively putting cyber work on equal footing decades-old divisions devoted to human spying and analysis.

The CIA’s focus is more narrow and targeted than that of the NSA, which is responsible for sweeping up electronic communications on a large scale around the globe. CIA efforts mainly focus on “close in” operations in which the agency at times relies on individuals to implant code on computer systems not connected to the Internet.

The CIA and NSA have historically been rivals in cyberspace, although, by some accounts, they increasingly have put aside institutional rivalries to join forces in gathering intelligence on adversaries, and they cooperated under the Obama administration in an operation code named Olympic Games aimed at disrupting Iran’s nuclear capability.

The WikiLeaks release revealed that they have sophisticated “stealth” capabilities that enable hackers not only to infiltrate systems, but evade detection, and abilities to “escalate privileges” or move inside a system as if they owned it.

“The only thing that separates NSA from commodity malware in the first place is their ability to remain hidden,” the former TAO hacker said. “So when you talk about the stealth components, it’s huge that you’re seeing a tangible example here of them using and researching stealth.”

The breach, if proven legitimate, adds to WikiLeaks’s expanding library of sensitive U.S. government documents, after previous releases of sensitive U.S. diplomatic cables and military records.

The leak is also likely to create political ripples for the Trump administration. Trump declared “I love WikiLeaks” last October during a campaign rally when he read from a trove of stolen emails about his Democratic opponent, Hillary Clinton.

Trump also initially sided with WikiLeaks, which disputed that its Clinton email archive had been stolen by hackers associated with Russian intelligence services. Trump dismissed the CIA’s conclusion that Russia was behind the hack, but has since said he now thinks Moscow may have been responsible.

‘Eyewash’: How the CIA deceives its own workforce about operations

As they roll out their Obamacare replacement plan, Republicans are quickly finding out what Democrats learned eight years ago: Even if you win control of Congress and the White House, there are still plenty of obstacles to passing laws that, in principle, your whole party agrees with.

Several factions within the Republican Party don’t like some key details about this new health-care plan. In fact, there’s enough opposition that these Republicans could derail the bill as it stands. It’s something President Trump appeared to acknowledge when he offered up in a tweet Tuesday morning the opportunity for “review and negotiation.”

Our wonderful new Healthcare Bill is now out for review and negotiation. ObamaCare is a complete and total disaster – is imploding fast!

— Donald J. Trump (@realDonaldTrump) March 7, 2017

Trump appears to have done his math. Assuming no Democrats in either chamber support the bill, Republicans can’t lose more than two GOP senators or 21 Republicans in the House. That doesn’t leave a lot of wiggle room.

Which means the factions opposed to Obamacare suddenly have a whole lot of leverage. Here’s a look at the three main ones:

1) Western/Midwestern GOP senators: Don’t touch Medicaid in our states

Sen. Rob Portman (R-Ohio). (Spencer Platt/Getty Images)

Who’s saying it: Sens. Rob Portman (Ohio), Shelley Moore Capito (W.Va.), Cory Gardner (Colo.) and Lisa Murkowski (Alaska) wrote this in a letter to Senate Majority Leader Mitch McConnell (R-Ky.), reported WaPo’s congressional team.

This faction could soon grow, says Molly Reynolds, a congressional analyst with the Brookings Institution. GOP senators in Nevada and Arizona, two states that adopted the Medicaid expansion, are up for reelection in 2018 and may be under pressure back home to protect millions of people from losing their Medicaid coverage — or the state having to bankroll those people. A significant number of Republican governors also want to keep the Medicaid expansion in place.

Their argument, explained: One of Obamacare’s primary tools to ensure that low-income Americans received coverage was to expand Medicaid to people above the poverty line, an expansion the federal government mostly paid for. (Over the years, Obamacare would wean states off federal funding.) Thirty-one states agreed to the plan.

These senators are saying that if you whittle down how much the federal government funds an expanded Medicaid program (as this plan does), you will leave states on the hook financially to cover all those people. Or those people will simply watch their coverage lapse.

That’s a lot of money. In fact, a January report by the nonpartisan Urban Institute found that Medicaid is the largest component of state spending in fiscal 2016 — almost a third of the budget.

2) Conservative/libertarian senators: Don’t subsidize people’s health care

Th House leadership plan is Obamacare Lite. It will not pass. Conservarives are not going to take it. #FullRepeal

— Senator Rand Paul (@RandPaul) March 7, 2017

Who’s saying it: Sen. Rand Paul (Ky.) — yes, the guy who led that quixotic crusade with a copy machine to try to find the “secret” Obamacare bill the other day — is one of the most vocal.

But there are also plenty of House Freedom Caucus members, that ultraconservative group of lawmakers who generally oppose increasing federal spending, joining him.

These lawmakers are buoyed by several influential conservative groups on the right that plan to oppose any bill they deem is not a “full repeal » — i.e. no tax credits.

Sen. Rand Paul (R-Ky.) criticizes the House Republican health-care reform plan as “Obamacare light” during a television interview on Capitol Hill on March 7. (J. Scott Applewhite/Associated Press)

“The fundamental question is, when we see the full plan, will it reduce health-care costs and will it do so over time?” said Rep. Mark Meadows (N.C.), chairman of the House Freedom Caucus. “And when will we see the repeal of Obamacare insurance mandates if this is enacted?”

3) The moderate Planned Parenthood supporters

Sen. Susan Collins (R-Maine). (J. Scott Applewhite/Associated Press)

Sen. Susan Collins (Maine) said in January that she was “not happy” about the prospect of tying Planned Parenthood and Obamacare together, but she stopped short of saying that would prevent her from supporting the GOP bill. In 2015, she teamed up with Murkowski to try to keep defunding language out of an earlier Obamacare repeal bill.

Collins told reporters in January that she thinks a “significant number” of House Republicans, such as Rep. Charlie Dent (Pa.), might join her.

The bottom line: We count six GOP senators with concerns about this bill and an unclear number of House Republicans — somewhere in the range of a dozen. In the Senate, six is four too many. And that probably means that the bill, as it was rolled out Tuesday, will have to change if Republicans want to get it to Trump’s desk anytime soon.
