A recent security analysis revealed that hackers can exploit a vulnerability in Microsoft Teams, allowing them to extract encrypted authentication tokens stored in a Chromium-like Cookies database on Windows. This technique, detailed by researcher Brahim El Fikhi, enables unauthorized access to users’ chats, emails, and files, posing significant risks for enterprises. Despite improvements in token storage from plaintext to encrypted formats, the reliance on Windows Data Protection API (DPAPI) creates new attack vectors, especially when local access is compromised. As Microsoft Teams continues to be a prime target for cyber threats, the findings underscore the need for enhanced monitoring and security measures to mitigate risks associated with token misuse and lateral movement within corporate environments.
