Rewterz Threat Alert – Muddy Water Summer Mirage Campaign – IOC’s

Severity

High

Analysis Summary

Prevailion uncovered two new malicious documents; one which discussed Stephen Moore’s appointment to the Federal Reserve, the second document discussed companies that extract and process crude oil. Both of these documents relied 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.
