The FBI and NSA have issued a joint report warning that Russian state hackers are using a previously unknown piece of Linux malware to stealthily infiltrate sensitive networks, steal confidential information, and execute malicious commands.

In a report that’s unusual for the depth of technical detail from a government agency, officials said the Drovorub malware is a full-featured tool kit that was has gone undetected until recently. The malware connects to command and control servers operated by a hacking group that works for the GRU, Russia’s military intelligence agency that has been tied to more than a decade of brazen and advanced campaigns, many of which have inflicted serious damage to national security.
