ESET researchers reveal their findings about POLONIUM, an advanced persistent threat (APT) group about which little information is publicly available and its initial compromise vector is unknown. POLONIUM is a cyberespionage group first documented by Microsoft Threat Intelligence Center (MSTIC) in June 2022.
MSTIC’s assessment is that POLONIUM is an operational group based in Lebanon, coordinating its activities with other actors affiliated with Iran’s Ministry of Intelligence and Security (MOIS).
According to ESET telemetry, POLONIUM has targeted more than a dozen organizations in Israel since at least September 2021, with the group’s most recent actions being observed in September 2022.
Verticals targeted by this group include engineering, information technology, law, communications, branding and marketing, media, insurance, and social services.
