About this tag
OAuth attacks on WindowsForum cover techniques that abuse the OAuth 2.0 protocol to bypass security controls, especially multi-factor authentication. A prominent example is device-code phishing, where attackers trick users into entering a code on a legitimate sign-in page, capturing OAuth tokens without needing passwords or MFA. This method has been weaponized in platforms like Kali365, which targets Microsoft 365 accounts. The discussions emphasize that MFA alone is insufficient against such attacks, and hardening identity infrastructure—such as conditional access policies and token hygiene—is critical for enterprise IT security.
