oauth consent abuse

OAuth consent abuse in Microsoft Entra ID (formerly Azure AD) is a growing threat where cybercriminals exploit the legitimate OAuth 2.0 consent flow to gain stealthy, password-less access to corporate resources, particularly email inboxes. By tricking users into granting delegated permissions to malicious applications, attackers bypass traditional authentication controls. This tag covers detection and defense strategies against such attacks, focusing on the abuse of consent prompts in Microsoft's identity platform. Topics include identifying high-risk app permissions, monitoring consent activity, and securing Entra ID configurations to prevent unauthorized mailbox access and data exfiltration.
