Are LLMs becoming messengers for attackers? #ai #cybersecurity

AI assistants with broad enterprise access are creating a new attack vector.

Chris Luft and Matt Bromiley discuss the Gemini Jack vulnerability, where attackers used prompt injection to turn Google's AI assistant into an unwitting accomplice in data exfiltration.

The attack embedded hidden instructions in documents or emails. When employees asked Gemini normal questions like "show me our budgets," the AI retrieved the poisoned document and executed the attacker's commands without anyone clicking anything.

Matt breaks down the shift in tactics: adversaries no longer need to do all the work themselves. They can simply ask the AI messenger to do it for them.

Traditional attacks require breaking into environments and stealing credentials. Prompt injection skips all of that through clever prompt engineering that weaponizes the AI's legitimate access.

Chris points out the uncomfortable reality: prompt injection is built into how LLMs process data. It's an architectural challenge that comes with giving AI assistants broad access to organizational information.

In this week's Intel Chat, Chris and Matt also break down React2Shell, Russian hacktivist indictments, and Chinese threat actor WarpPanda.
