[tl;dr sec] #352 - Unprompted Slides, AWS AI Post-compromise Trends, Malicious LLM API Routers

A newsletter roundup covering artificial intelligence (AI) security conference talks, cloud vulnerability research, and large language model (LLM) post-compromise behavior studies. Key findings include Azure application programming interface (API) connection flaws enabling cross-tenant compromise, LLM tendencies in AWS post-compromise scenarios, malicious LLM application programming interface (API) routers exfiltrating secrets and credentials, and prompt injection attacks manipulating security classifiers through counterfeit policy injection.

Why it matters: Cloud security teams should review Azure Logic Apps API Connections for cross-tenant exposure; defenders need to understand that LLM-driven post-compromise tradecraft mirrors human attacker behavior and existing detection strategies apply; organizations using third-party LLM API routers face credential and token theft risks and should validate router trustworthiness; security teams relying on LLM classifiers must test for prompt injection vulnerabilities that can override detection logic.
