Identifies Entra ID device code authentication flows where multiple user agents are observed within the same session. This pattern is indicative of device code phishing, where an attacker's polling client (e.g., Python script) and the victim's browser both appear in the same authentication session. In legitimate device code flows, the user authenticates via browser while the requesting application polls for tokens - when these have distinctly different user agents (e.g., Python Requests vs Chrome), it may indicate the code was phished and redeemed by an attacker.
