Analysis Summary
Shuckworm APT – aka Actinium, Armageddon, Primitive Bear, Gamaredon, and Trident Ursa – is a Russia-backed advanced persistent threat (APT) that has been operating since at least 2013. This cyber-espionage group is known to target government, military, and other high-value targets, primarily in Ukraine and has been linked to several advanced persistent threats (APT) campaigns. 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. The Gamaredon APT group’s recent attack leverages a decree document from the Russian Federation government as bait. In July, this APT group targets Ukrainian entities with PowerShell info-stealer malware dubbed GammaLoad.
It is important for organizations to take steps to protect themselves and to have a robust incident response plan in place. This includes implementing strong security controls, regularly monitoring networks for signs of compromise, and being aware of the group’s tactics, techniques, and procedures (TTPs) so that they can quickly detect and respond to attacks.
