Multi-user device-code sign-ins from ARToken capture IPs
Detects anomalous device-code authentication attempts from multiple distinct users originating from known ARToken PhaaS platform egress IP addresses within a 3-day window. This behavior is indicative of a bulk token-capture operation, where an attacker leverages an Adversary-in-the-Middle (AiTM) phishing framework to harvest credentials and session tokens from multiple users.
