Anti-secrecy group WikiLeaks on Tuesday published what it said were thousands of pages of internal CIA discussions about hacking techniques used over several years, renewing concerns about the security of consumer electronics and embarrassing yet another U.S. intelligence agency.
The discussion transcripts showed that CIA hackers could get into Apple Inc iPhones, Google Inc Android devices and other gadgets in order to capture text and voice messages before they were encrypted with sophisticated software.
Cyber security experts disagreed about the extent of the fallout from the data dump, but said a lot would depend on whether WikiLeaks followed through on a threat to publish the actual hacking tools that could do damage.
Reuters could not immediately verify the contents of the published documents, but several contractors and private cyber security experts said the materials, dated between 2013 and 2016, appeared to be legitimate.
A longtime intelligence contractor with expertise in U.S. hacking tools told Reuters the documents included correct "cover" terms describing active cyber programs.
Among the most noteworthy WikiLeaks claims is that the Central Intelligence Agency, in partnership with other U.S. and foreign agencies, has been able to bypass the encryption on popular messaging apps such as WhatsApp, Telegram and Signal.
The files did not indicate the actual encryption of Signal or other secure messaging apps had been compromised.
The information in what WikiLeaks said were 7,818 web pages with 943 attachments appears to represent the latest breach in recent years of classified material from U.S. intelligence agencies.
Security experts differed over how much the disclosures could damage U.S. cyber espionage. Many said that, while harmful, they do not compare to former National Security Agency contractor Edward Snowden's revelations in 2013 of mass NSA data collection.
"This is a big dump about extremely sophisticated tools that can be used to target individual user devices ... I haven’t yet come across the mass exploiting of mobile devices," said Tarah Wheeler, senior director of engineering and principal security advocate for Symantec.
Stuart McClure, CEO of Cylance, an Irvine, California, cyber security firm, said that one of the most significant disclosures shows how CIA hackers cover their tracks by leaving electronic trails suggesting they are from Russia, China and Iran rather than the United States.
Other revelations show how the CIA took advantage of vulnerabilities that are known, if not widely publicized.
In one case, the documents say, U.S. and British personnel, under a program known as Weeping Angel, developed ways to take over a Samsung smart television, making it appear it was off when in fact it was recording conversations in the room.
The CIA and White House declined comment. "We do not comment on the authenticity or content of purported intelligence documents," CIA spokesman Jonathan Liu said in a statement.
Google declined to comment on the purported hacking of its Android platform, but said it was investigating the matter.
Snowden on Twitter said the files amount to the first public evidence that the U.S. government secretly buys software to exploit technology, referring to a table published by WikiLeaks that appeared to list various Apple iOS flaws purchased by the CIA and other intelligence agencies.
Apple Inc did not respond to a request for comment.
The documents refer to means for accessing phones directly in order to catch messages before they are protected by end-to-end encryption tools like Signal.
Signal inventor Moxie Marlinspike said he took that as "confirmation that what we’re doing is working." Signal and the like are "pushing intelligence agencies from a world of undetectable mass surveillance to a world where they have to use expensive, high-risk, extremely targeted attacks."
CIA CYBER PROGRAMS
The CIA in recent years underwent a restructuring to focus more on cyber warfare to keep pace with the increasing digital sophistication of foreign adversaries. The spy agency is prohibited by law from collecting intelligence that details domestic activities of Americans and is generally restricted in how it may gather any U.S. data for counterintelligence purposes.
The documents published Tuesday appeared to supply specific details to what has been long-known in the abstract: U.S. intelligence agencies, like their allies and adversaries, are constantly working to discover and exploit flaws in any manner of technology products.
Unlike the Snowden leaks, which revealed the NSA was secretly collecting details of telephone calls by ordinary Americans, the new WikiLeaks material did not appear to contain material that would fundamentally change what is publicly known about cyber espionage.
WikiLeaks, led by Julian Assange, said its publication of the documents on the hacking tools was the first in a series of releases drawing from a data set that includes several hundred million lines of code and includes the CIA's "entire hacking capacity."
The documents only include snippets of computer code, not the full programs that would be needed to conduct cyber exploits.
WikiLeaks said it was refraining from disclosing usable code from CIA's cyber arsenal "until a consensus emerges on the technical and political nature of the C.I.A.’s program and how such ‘weapons’ should be analyzed, disarmed and published."
U.S. intelligence agencies have said that Wikileaks has ties to Russia's security services. During the 2016 U.S. presidential campaign, Wikileaks published internal emails of top Democratic Party officials, which the agencies said were hacked by Moscow as part of a coordinated influence campaign to help Republican Donald Trump win the presidency.
WikiLeaks has denied ties to Russian spy agencies.
Trump praised WikiLeaks during the campaign, often citing hacked emails it published to bolster his attacks on Democratic Party candidate Hillary Clinton.
WikiLeaks said on Tuesday that the documents showed that the CIA hoarded serious security vulnerabilities rather than share them with the public, as called for under a process established by President Barack Obama.
Rob Knake, a former official who dealt with the issue under Obama, said he had not seen evidence in what was published to support that conclusion.
The process "is not a policy of unilateral disarmament in cyberspace. The mere fact that the CIA may have exploited zero-day [previously undisclosed] vulnerabilities should not surprise anyone," said Knake, now at the Council on Foreign Relations.
U.S. officials, speaking on condition of anonymity, said they did not know where WikiLeaks might have obtained the material.
In a press release, the group said, "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."
U.S. intelligence agencies have suffered a series of security breaches, including Snowden's.
In 2010, U.S. military intelligence analyst Chelsea Manning provided more than 700,000 documents, videos, diplomatic cables and battlefield accounts to Wikileaks.
Last month, former NSA contractor Harold Thomas Martin was indicted on charges of taking highly sensitive government materials over a course of 20 years, storing the secrets in his home.
