About this tag
TeamFiltration is a legitimate penetration testing framework designed for ethical cloud security assessments, but it has been weaponized in the UNK_SneakyStrike cyberattack campaign. Threat actors have abused TeamFiltration to conduct password spraying attacks against Microsoft Entra ID (formerly Azure Active Directory) accounts, targeting over 80,000 user accounts across hundreds of organizations. The attacks exploit Microsoft cloud services including Teams, Outlook, and OneDrive, using the tool's legitimate capabilities to bypass security measures. This tag covers discussions about how TeamFiltration is misused, the mechanics of password spraying, and defensive strategies for protecting Office 365 and Entra ID environments from such identity-based attacks.
