Web Credential Harvesting via Phishing Proxy

T1557 · MITRE ATT&CK

A proxy-based adversary-in-the-middle (AiTM) phishing attack relays a user's sign-in with a legitimate identity service. When the user completes MFA that is not phishing-resistant, the relay may expose credentials and receive an authenticated session cookie or token; later session use may not require a new MFA prompt. Phishing-resistant MFA is designed to resist this relay.
