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)


The sample we analyzed was a trojanized version of VPN software.  Upon execution, this software loads and activates the malware which starts obtaining information about the system and waiting to receive commands. 















So now what? Is there a way to protect yourself from Havex?

Well that’s the good news—HP TippingPoint customers are protected from this malware’s outbound communication attempts. Next Tuesday a specific filter, 16455, will be published in our HP TippingPoint DVLabs weekly Digital Vaccine package for full coverage. In the interim, please contact HP TippingPoint support or your local Solution Architect to receive a custom filter for immediate use.
