Rewterz Threat Alert – Iranian APT Group “MuddyWater” Resurfaces

Severity

High

Analysis Summary

The Iranian cyber criminal group MuddyWater has resurfaced. The group primarily has targeted Middle Eastern, European and North American nations. The industries under target include telecommunications, government (IT services), and oil sectors. Indicators of compromise are given below.

Most of the campaigns by MuddyWater are designed upon socially engineering their victims into enabling macros in order to infect the targeted workstation. Once macros were enabled, the threat actor-written code would attempt to obtain a trojan hosted on an adversarial payload command and control node. This was a fully functional remote access trojan, that would allow the threat actors to interact with the compromised workstation via the adversarial interactive command and control node.

Impact

• Credential Theft
• Theft of sensitive information
