Why it matters

Morris II demonstrates that connected GenAI applications can be abused for zero-click, self-propagating prompt-injection attacks, a class of agentic-AI threat defenders should understand before such systems become ubiquitous.

A Zyber YouTube video explains Morris II, a controlled research demonstration by Stav Cohen, Ron Bitton, and Ben Nassi showing how self-replicating adversarial prompts can create a worm-like chain reaction across connected generative-AI applications such as AI-powered email assistants. The video frames it as a security experiment revealing a possible future risk, not an active outbreak, and points to the arXiv paper and IBM overview as sources.
