Internet and computer security company Symantec has issued a statement today related to the Vault 7 WikiLeaks documents leaked from the CIA, saying that the methods and protocols described in the documents are consistent with cyberattacks they’d been tracking for years.
Symantec says they now believe that the CIA hacking tool Fluxwire is a malware that had been known as Corentry, which Symantec had previously attributed to an unknown cyberespionage group called Longhorn, which apparently was the CIA.
They described Longhorn as having been active since at least 2011, and responsible for attacks in at least 16 countries across the world, targeting governments and NGOs, as well as financial, energy, and natural resource companies, things that would generally be of interest to a nation-state.
While the WikiLeaks themselves have been comparatively short on details, as WikiLeaks continues to share specific vulnerabilities with companies so they can fix them before the details are leaked to the general public, the ability of security companies like Symantec to link the CIA to known hacking operations could prove to be even more enlightening as to the scope of CIA cyber-espionage the world over.
Today, March 31st 2017, WikiLeaks releases Vault 7 "Marble" -- 676 source code files for the CIA's secret anti-forensic Marble Framework. Marble is used to hamper forensic investigators and anti-virus companies from attributing viruses, trojans and hacking attacks to the CIA.
Marble does this by hiding ("obfuscating") text fragments used in CIA malware from visual inspection. This is the digital equivallent of a specalized 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.
Marble forms part of the CIA's anti-forensics approach and the CIA's Core Library of malware code. It is "[D]esigned to allow for flexible and easy-to-use obfuscation" as "string obfuscation algorithms (especially those that are unique) are often used to link malware to a specific developer or development shop."
The Marble source code also includes a deobfuscator to reverse CIA text obfuscation. Combined with the revealed obfuscation techniques, a pattern or signature emerges which can assist forensic investigators attribute previous hacking attacks and viruses to the CIA. Marble was in use at the CIA during 2016. It reached 1.0 in 2015.
