When the source code to a suspected Russian-made malware leaked online in 2013, guess who used it? A new release from WikiLeaks claims the U.S. CIA borrowed some of the code to bolster its own hacking operations.
On Friday, WikiLeaks released 27 documents that allegedly detail how the CIA customized its malware for Windows systems.
The CIA borrowed a few elements from the Carberp financial malware when developing its own hacking tool known as Grasshopper, according to those documents.
Carberp gained infamy as a Trojan program that can steal online banking credentials and other financial information from its victims' computers. The malware, which likely came from the criminal underground, was particularly problematic in Russia and other former Soviet states.
