Case · DiggingBeagle record
USENIX Security 2026 research showed that subtle pixel modulation can induce controllable electromagnetic emissions on digital video cables while keeping the screen visually unchanged to observers.
Peer-reviewed laboratory covert-channel research. It demonstrates a physical output path, not autonomous AI escape or a documented real-world intrusion.

A containment design that restricts networking but leaves software broad control over display output should treat the display subsystem and its cables as part of the physical communications boundary, while keeping TrojPix's reported throughput and range specific to the tested hardware and receiver conditions.

Citation guidanceWhy this archive exists
DiggingBeagle is a non profit research project documenting AI security incidents, agent failures, vulnerabilities and AI-assisted operations. A case keeps its claims beside the sources that support, contest or limit them. Later updates stay visible, so a reader can see when the account changed.
We publish case reconstructions, dated reporting and analysis across records. Each has a different evidentiary role. About the project and our methodology explain how the work is reviewed.
