VERMONSTER
VERMONSTER is a malware family used by the Russia-linked threat actor TEMP.Vermin, which CERT-UA has linked to security agencies of the so-called Luhansk People’s Republic (LPR/LNR). Google Threat Intelligence Group reporting places VERMONSTER in campaigns targeting the defense industrial base and military-related organizations connected to the Russia-Ukraine war. TEMP.Vermin deployed VERMONSTER alongside SPECTRUM (also reported publicly as Spectr) and FIRMACHAGENT using lure content and themed infrastructure related to drone production and development, anti-drone defense systems, video surveillance security systems, and broader aerospace themes. The malware has been described in the context of surveillance and drone/anti-drone operations. High-confidence reporting in the provided content does not include specific technical details on VERMONSTER’s internal functionality, persistence mechanisms, command-and-control, or concrete indicators of compromise beyond its association with TEMP.Vermin and the lure themes used in delivery.
