Microsoft Self-Service Password Reset Azure Account Takeover | MSSP Advisory

A threat actor is exploiting Microsoft's legitimate Self-Service Password Reset feature to gain unauthorized access to Azure AD environments and steal data from Microsoft 365 and Azure production systems. The attack chain uses valid administrative functions to reset passwords and create persistence mechanisms, making detection difficult through standard security monitoring. The campaign specifically targets production environments where business-critical data resides.

Your RMM and PSA platforms likely authenticate through Azure AD, making your entire client management stack vulnerable if this attack vector succeeds against your tenant. Every client running Microsoft 365 or Azure services faces immediate data theft risk, and you carry the advisory obligation to warn them about password reset policy vulnerabilities that most organizations never properly configured.
