EvilGnome Spyware Targets Linux Users

New research has revealed a rare piece of spyware called EvilGnome that's designed to spy on unsuspecting Linux desktop users.

Known as EvilGnome, all Linux workstation users are at risk of a new backdoor threat which implants spying software capable of recording your screen, keyboard and mouse click functions. Reports are also debating whether this parasite is able to steel actual files from the PC without user interaction or warning, or even has the ability to distribute other malware – this makes the threat much higher priority than other types of vulnerability.

There is no known patch for EvilGnome as yet, but industry experts recommend updating your Linux antivirus and patching to the latest version – something Windows users are all too familiar with.

EvilGnome Spyware Modules

The Spy Agent of EvilGnome contains five malicious modules called “Shooters,” as explained below:

  • ShooterSound — this module uses PulseAudio to capture audio from the user’s microphone and uploads the data to the operator’s command-and-control server.
  • ShooterImage — this module uses the Cairo open source library to captures screenshots and uploads them to the C&C server. It does so by opening a connection to the XOrg Display Server, which is the backend to the Gnome desktop.
  • ShooterFile — this module uses a filter list to scan the file system for newly created files and uploads them to the C&C server.
  • ShooterPing — the module receives new commands from the C&C server, like download and execute new files, set new filters for file scanning, download and set new runtime configuration, exfiltrate stored output to the C&C server, and stop any shooter module from running.
  • ShooterKey — this module is unimplemented and unused, which most likely is an unfinished keylogging module.
