Russia-linked threat actor RomCom targeted Ukrainian government agencies and Polish entities in cyber attacks since late 2023.
RomCom deployed an updated variant of the RomCom RAT called 'SingleCamper' and used two new downloaders, RustClaw and MeltingClaw, along with two backdoors, DustyHammock and ShadyHammock.
RomCom is focusing on data exfiltration from Ukrainian targets, using various tools and malware languages for long-term espionage access.
The group employed spear-phishing messages and established remote tunnels using PuTTY's Plink tool to connect with attacker-controlled servers.
