FBI Warns of Sophisticated OAuth Consent Phishing Campaign Targeting Prominent Figures
The FBI issued a public alert in late 2025 regarding a sophisticated OAuth consent phishing campaign targeting high-profile individuals, their family members, and associates through commercial messaging applications. Attackers impersonate government officials, journalists, and public personalities to trick victims into granting access to legitimate cloud services like Microsoft or Google under the pretense of reviewing documents. Once OAuth permissions are granted, attackers gain persistent access to emails, files, and sensitive data that cannot be revoked simply by changing passwords, requiring victims to manually invalidate tokens in application security settings. This campaign highlights the growing trend of identity-centric attacks that bypass traditional security measures including multi-factor authentication, representing a significant evolution in social engineering tactics that exploit trusted authentication protocols against prominent targets.
