Hydra: A Secure Way to Use AI Agents
AI Agents Have an Isolation Problem Security researcher Simon Willison identified what he calls the “lethal trifecta” of AI agent risk: simultaneous access to private data, the ability to communicate externally, and processing of untrusted content. Most agent frameworks today combine all three on your host machine, with full access to your filesystem, credentials, and shell. The pattern is familiar: install a framework, give it your API keys, and let it run bash commands as your user. It works, until a prompt injection in a fetched webpage tells the agent to cat ~/.ssh/id_rsa, or a malicious community plugin harvests your AWS credentials. In the past year, security researchers have documented exposed API keys and OAuth tokens from agent frameworks leaking to the public internet, remote code execution vulnerabilities, and malicious marketplace integrations containing credential-stealing code. ...
