Research auditing 33,000 trajectories from eleven open-weight AI agents shows that low attack success rates in indirect prompt injection (IPI) may mask vulnerabilities. Current benchmarks treat failed attacks as defenses, potentially overlooking subtle hijacking of tool calls.

AI-assisted summary based on the listed source.
Tool-using agents read untrusted external content, which exposes them to indirect prompt injection (IPI), where hidden instructions hijack the agent's tool calls. Benchmarks measure IPI security by the attack success rate (ASR), which treats every failed attack as a successful defense. To test this assumption, we...
Understanding the true security posture of tool-using AI agents is critical as they interact with untrusted external content. This insight urges a reevaluation of how IPI defenses are measured to better protect AI systems from hidden manipulation.
Security-conscious readers may want to review the source and watch for practical exposure or mitigation details.
VQV organizes public signals from inspectable sources. It does not independently verify the underlying report.
Signal Strength reflects source quality, relevance, freshness and evidence. Public Interest helps organize discovery; it is not proof of truth.
VQV surfaced this signal because it is recent, relevant to AI Security, connected to arXiv.
