The Russian Sandworm group, a cyber-espionage unit with ties to the Russian military, is actively targeting Windows users in Ukraine. They are distributing malicious Microsoft Key Management Service (KMS) activators and fake Windows updates, compromising systems in the process. This campaign, which likely started in late 2023, showcases the ongoing cyber warfare efforts targeting Ukraine.

EclecticIQ threat analysts have linked these attacks to Sandworm based on overlapping infrastructure, consistent tactics, techniques, and procedures (TTPs), and the use of ProtonMail accounts to register domains used in the attacks. The attackers are also deploying a BACKORDER loader to deliver DarkCrystal RAT (DcRAT) malware. This malicious tool abuses legitimate Windows processes to evade detection, such as using `wmic` to add Microsoft Defender exclusions and `reg` to gather information about Defender's status, mimicking the behavior of legitimate KMS activators, while injecting malicious payloads onto compromised systems.
