WikiLeaks’ latest disclosure of CIA cyber-tools reveals a technique used by the agency to hide its digital tracks, potentially blowing the cover on current and past hacking operations aimed at gathering intelligence on terrorists and other foreign targets.
The release Friday of the CIA’s “Marble Framework” comes less than a month after the WikiLeaks dumped onto the Internet a trove of files — dubbed “Vault 7” — that described the type of malware and methods the CIA uses to gain access to targets’ phones, computers and other electronic devices.

“This appears to be one of the most technically damaging leaks ever done by WikiLeaks, as it seems designed to directly disrupt ongoing CIA operations and attribute previous operations,” said Nicholas Weaver, a computer security researcher at the University of California at Berkeley.
The material includes the secret source code of an “obfuscation” technique used by the CIA so its malware can evade detection by anti-virus systems. The technique is used by all professional hackers, whether they work for the National Security Agency, Moscow’s FSB security agency or the Chinese military. But because the code contains a specific algorithm — a digital fingerprint of sorts — it can now be used to identify CIA hacking operations that had previously been detected but not attributed.
“It’s one thing to say, ‘I got hacked.’ It’s another thing to say, ‘I got hacked by the CIA,’ ” said Jake Williams, founder of Rendition InfoSec, a cybersecurity firm. “I suspect this could cause some foreign policy issues down the road.”
If this source code is used in a majority of CIA hacking operations, Williams said, the release could be “devastating.”
WikiLeaks, founded by Julian Assange, has sought to position itself as a champion of transparency and defender of privacy rights. It described the Marble Framework as “the digital equivalent of a specialized CIA tool to place covers over the English language text on U.S. produced weapons systems before giving them to insurgents secretly backed by the CIA.”
In releasing the material, WikiLeaks tweeted: “CIA Vault 7 Part 3 ‘Marble’ — thousands of CIA viruses and hacking attacks could now be attributed.”
The agency responded angrily.
“Dictators and terrorists have no better friend in the world than Julian Assange, as theirs is the only privacy he protects,” spokesman Dean Boyd said, without commenting on the authenticity of the release.
“The American public should be deeply troubled by any WikiLeaks disclosure designed to damage the intelligence community’s ability to protect America against terrorists and other adversaries,” Boyd said. “Such disclosures not only jeopardize U.S. personnel and operations but also equip our adversaries with tools and information to do us harm.’’
