SLIDING INTO YOUR DMS: ABUSING MICROSOFT TEAMS FOR MALWARE DELIVERY

Summary from the TLDR InfoSec newsletter

Attackers are increasingly using Microsoft Teams for the delivery of malware. Impersonating IT support, they send direct messages or calls from fake or compromised accounts, tricking users into installing remote access tools or running malicious PowerShell payloads. These sophisticated campaigns leverage social engineering, exploit the trust in Teams' internal messaging, and use advanced techniques to steal credentials, maintain persistence, and evade detection. Defenders are advised to remain vigilant for unusual Teams activity and impersonation attempts and to recognize the signs of such malware attacks for improved response and mitigation.
