New DarkGate malware targets Windows users in France and Spain

  • EnSilo researchers discovered a new cryptomining and ransomware campaign distributing malware dubbed DarkGate. The malware has multiple evasion techniques, allowing it to remain undetected by most antivirus solutions over long periods of time. DarkGate was found to bear similarities with a previously identified malware named Golroted.
  • DarkGate utilizes two infection methods that rely on distribution via Torrent files disguised as popular films and TV shows, that execute malicious VBScripts on victims’ devices. The malware was discovered to be capable of cryptomining, credential stealing, ransomware and remote-access takeovers.  
  • DarkGate targets Windows workstations, and has so far been aimed at users in Europe, particularly in France and Spain.
