Top 10 Malware Q3 2025

MS-ISAC’s Q3 2025 Top 10 Malware report highlights a 38% quarter-over-quarter rise in detections, with SocGholish remaining dominant and multiple families (CoinMiner, Agent Tesla, TeleGrab, ZPHP, VenomRAT, Gh0st, NanoCore, Lumma Stealer, Jinupd) actively observed. The briefing outlines prevailing initial infection vectors (dropped, malspam, malvertisement, multiple), notes the return or first appearance of several families (e.g., Gh0st, Lumma Stealer post-takedown, and Jinupd), and supplies extensive IOCs (domains and SHA256 hashes) to support detection, hunting, and prevention across SLTT organizations.
