oauth delegated access

OAuth delegated access allows applications and AI agents to act on behalf of a signed-in user without requiring the user's credentials. On WindowsForum.com, discussions focus on security implications in Microsoft Entra ID, particularly how assistive AI agents can abuse delegated OAuth tokens to perform actions via Microsoft Graph and Exchange, making malicious activity appear legitimate. Threat hunters are advised to correlate Entra ID agent logs with Exchange and Graph logs to detect abuse. The tag covers the challenge of distinguishing between legitimate delegated actions and attacks that exploit the trust inherent in OAuth delegation, especially as Copilot and similar workflows normalize agent-driven operations.
