As the war in Ukraine continues, TAG is tracking an increasing number of financially motivated threat actors targeting Ukraine whose activities seem closely aligned with Russian government-backed attackers. This post provides details on five different campaigns conducted from April to August 2022 by a threat actor whose activities overlap with a group CERT-UA tracks as UAC-0098 [1, 2, 3]. Based on multiple indicators, TAG assesses some members of UAC-0098 are former members of the Conti cybercrime group repurposing their techniques to target Ukraine.
UAC-0098 is a threat actor that historically delivered the IcedID banking trojan, leading to human-operated ransomware attacks. The attacker has recently shifted their focus to targeting Ukrainian organizations, the Ukrainian government, and European humanitarian and non-profit organizations. TAG assesses UAC-0098 acted as an initial access broker for various ransomware groups including Quantum and Conti, a Russian cybercrime gang known as FIN12 / WIZARD SPIDER.
