Rewterz Threat Alert – AveMaria RAT Targeting Ukraine – Active IOCs

Severity

Medium

Analysis Summary

AveMaria RAT – aka WarzoneRAT – is a remote access trojan that targets Windows systems that provides the capability to gain unauthorized access to a victim’s PC or allow covert surveillance of it. It acts as a keylogger, can steal passwords, escalate privileges, and much more. AveMaria, like most malware, first arrives at systems as a result of phishing emails (as invoices and shipping orders), but is also available on the dark web for subscriptions. This malware-as-a-service RAT is written in C++ that has been available for purchase since at least 2018.

Recently, this AveMaria Rat was observed directing its most recent spam campaign at Ukraine with the email subject: Iнформацiя про спiвробiтникiв 2022. (Information about employees 2022.)

The email contains 4 lnk files and 3 decoy documents
