Cyber Stealer is a stealer malware family identified by eSentire’s Threat Response Unit (TRU), first seen in May 2025. The available content characterizes it as a new, feature-rich credential/data-stealing capability, but does not attribute it to a specific named threat actor, country, or subgroup, nor does it provide confirmed targeting details, victimology, or a distinct TTP set beyond its role as a stealer/credential-harvesting malware.
