Johann Rehberger, Red Team Director, speaks at [un]prompted 2026 on: Your Agent Works for Me Now.

Agentic AI used in personal assistants, developer tools, and enterprise platforms can be infected with promptware, engineered prompts that act like malware.
This talk demonstrates attacks and exploit chains, including delayed tool invocation and intent activation tricks that bypass existing mitigations. Attacks enable persistence, lateral movement across agentic systems, promptware-powered C2, and data exfiltration.
Several of the exploit demos have not been publicly disclosed before, including attacks against Gemini, Copilot and others.
Many of these issues are not edge cases or unknown problems. Even where simple fixes exist, new and more powerful AI systems keep reintroducing known vulnerability classes while increasing scale and blast radius at the same time. By shipping agents with insecure defaults, responsibility is pushed onto end users.
