AI agents aren’t just “tools” anymore — they’re getting delegated access, running workflows, calling APIs, and making decisions inside your environment. That’s why some security folks are starting to call them malware… with permission.
In this episode of Legitimate Cybersecurity, hosts Frank Downs and Dustin Brewer sit down with Jasson Casey (CEO & Co-Founder of Beyond Identity) to break down what actually breaks in identity and access when software can reason, plan, and take real actions. We cover why prompt injection is fundamentally “control + data mixing,” why agent toolchains resemble living-off-the-land techniques, and why visibility + device-bound identity may be the only sane control plane going forward.
You’ll learn:
Why “delegated auth” becomes the new breach primitive
How indirect prompt injection can persist across an agent loop
What “treat the agent as a user” gets right—and what it misses
Why hardware attestation (TPM/TEE) changes detection and logging strategy
How to think about local agents, plugins, and “willful malware execution” risk
