DEF CON 34 – Yaara Shriki – AI Gateway auth bypass leading to cloud compromise

This rule detects potentially unauthorized or suspicious administrative actions in an Azure environment following a login to specific AI-related applications (AI Gateway, LLM Proxy, or Model Router). It triggers when a user authenticates without applying Conditional Access policies or without Multi-Factor Authentication (MFA), followed immediately (within 30 minutes) by sensitive Azure administrative operations such as role assignments, Key Vault access, or VM write operations.
