Are hackers wreaking Havex on your network?

Havex, also referred to as “Energetic Bear,” is a piece of Windows malware that is actively being utilized in the wild in attacks against critical infrastructure, specifically targeting the energy sector in Western Europe and North America. This threat to enterprise security is a remote access Trojan (RAT) that is used to perform reconnaissance and assist in delivering additional payloads to the target. Once installed, it fingerprints the victim machine (users, files, directories, etc.) it sends and receives information from compromised PHP web servers.

 

Havex can be delivered to the target in multiple ways:

  • Spam/Phishing
  • Watering-hole attacks
  • Exploit Kits (Hello/Lights Out)
  • Masquerading as a legitimate (trojanized) download

 Let’s take a look at a sample of this malware (SHA1: 7f249736efc0c31c44e96fb72c1efcc028857ac7)
