Step-Zero Attack: Agent Safety Before Observability
Researchers demonstrate Step-Zero attacks where coding agents suffer harm during initial processing of archives or network responses before content reaches the model context. The evaluation spans multiple harnesses and models.
why this severityDemonstrated attack by researchers with no known real-world exploitation.
