Rewterz Threat Alert – Gamaredon Attacking Ukraine – Active IOCs

Severity

High

Analysis Summary

Ukraine has been the target of cyberattacks from the end of 2021 as tensions between the country and Russia have increased drastically. Although no threat group can be attributed to these attacks, Gamaredon is an obvious contender considering it’s past activities and affiliation with Russian Federation. 

Gamaredon is a Russia-backed advanced persistent threat (APT) that has been operating since at least 2013. The main goal of this APT is to use the malicious document to gain control of the target machine. The exploit document uses the template injection technique to infect the victim’s computer with further malware. When the document is opened, it connects to the hacker’s server and downloads the payload file. Gamaredon’s tools are simple and designed to collect sensitive information from hacked systems and propagate it further. Its information-gathering efforts are nearly comparable to those of a second-tier APT, whose primary purpose is to collect and disseminate information with their units.
