Hackers Leverage Microsoft Teams to Spread Matanbuchus 3.0 Malware to Targeted Firms
Posted: Sat Jul 19, 2025 2:02 pm
Cybersecurity researchers have flagged a new variant of a known malware loader called Matanbuchus that packs in significant features to enhance its stealth and evade detection.
Matanbuchus is the name given to a malware-as-a-service (MaaS) offering that can act as a conduit for next-stage payloads, including Cobalt Strike beacons and ransomware.
First advertised in February 2021 on Russian-speaking cybercrime forums for a rental price of $2,500, the malware has been put to use as part of ClickFix-like lures to trick users visiting legitimate-but-compromised sites not running it.
