WikiLeaks dumped the source code of a CIA tool called Marble. The tool is a code obfuscation tool that scrambles code so human operators can’t read it and antivirus engines can’t assign it to a known malware family. The WikiLeaks dump conveniently came a day after the Senate’s open hearing on Russian election interference. The Marble framework reached v1.0 in 2015 and was used as late as 2016, WikiLeaks says. The source code is available for download from here and the documentation page is here.
