How Hackers Are Exploiting Microsoft Teams to Spread Malware

In July 2025, a sophisticated cyberattack campaign has emerged, leveraging Microsoft Teams to deploy Matanbuchus 3.0, a potent malware loader. This evolved version of Matanbuchus, available as a Malware-as-a-Service for as little as $2,500 on crime forums, boasts advanced stealth features like improved communication protocols, in-memory execution, and enhanced obfuscation. According to Morphisec, attackers are using social engineering tactics, impersonating IT help desk personnel via Teams calls to trick employees into granting remote access through Quick Assist. This campaign highlights the growing danger of trusted platforms being weaponized, making it critical for organizations to stay vigilant.
