FBI Raises Alarm About OAuth Consent Phishing Activity
The FBI has issued a public warning about an active phishing campaign that exploits OAuth consent flows, a legitimate authorization mechanism used across countless apps and services. The technique is sophisticated enough to warrant a formal federal alert.
Why this matters: OAuth consent phishing is dangerous because it does not need your password. Instead, it tricks you into clicking 'Allow' on what looks like a normal login screen, handing attackers real access to your accounts through a permission your system trusts. No stolen credential, no brute force — just a button click. If your organization uses cloud apps, email, or any single sign-on setup, this is a live threat right now, not a theoretical one. The FBI issuing a warning means they are seeing this work in the wild.
