Unit 42 researchers identified six new remote access Trojan variants deployed by Iran-nexus APT group Screening Serpens between February and April 2026, coinciding with a regional conflict starting February 28, 2026. The group targeted entities in the U.S., Israel, UAE, and other Middle Eastern locations, primarily focusing on technology sector professionals through highly tailored social engineering using personalized recruitment lures. Two new malware families, MiniUpdate and MiniJunk V2, were discovered featuring advanced techniques including AppDomainManager hijacking that manipulates .NET application initialization to disable security mechanisms. The campaigns demonstrated increased technical capabilities and operational resilience, with each variant using dedicated C2 infrastructure hosted on Azure. The attacks leveraged DLL sideloading, scheduled tasks for persistence, and sophisticated evasion techniques to maintain long-term access for espionage purposes.
