#17: The Autonomous Adversary

Top Story: LiteLLM, Hit Again. This Time the Whole Gateway Falls — An AI "gateway" is the traffic controller that sits between your applications and the models they call. ⚔️ Attack: SearchLeak. One booby-trapped link could have turned Microsoft 365 Copilot into a silent data thief. Microsoft has already fixed it. — Varonis demonstrated the chain (they did not find it used in the wild): a crafted, Microsoft-hosted search link carried hidden instructions that Copilot read and obeyed, then quietly exfiltrated whatever the victim could access: emails, files, calendar. 🔬 Research: a guard for AI agents cut attack success from 7-in-10 to about 1-in-40. — A new study (AgentRedBench / AgentRedGuard) built a way to stress-test agents that plug into business tools (email, CRM, ticketing) by hiding malicious instructions in the data those tools return, then measured how often the agent got hijacked. 🛡️ Defense: Microsoft says it's now using a team of AI agents to hunt security bugs in its own software at machine speed, and credits them with 10 of this month's fixes. — In a public write-up, Microsoft described an internal system (codename MDASH) that turns a panel of specialized AI agents loose on its hardest-to-review code (the core of Windows, its virtualization layer, and its identity systems) to find, confirm, and help patch flaws, feeding the results into the same code-review and patching pipelines its engineers already use.
