 STAC (Sequential Tool Attack Chaining) is a multi-turn attack framework targeting tool-enabled LLM agents, where sequences of individually benign tool calls combine to produce harmful operations that only become apparent at the final step. With 483 systematically generated attack cases and an average attack success rate exceeding 90%, STAC reveals a fundamental security blind spot in current agent architectures: per-call safety checks cannot detect threats that emerge from the cumulative effect of tool sequences. STAC (Sequential Tool Attack Chaining) is a multi-turn attack framework targeting tool-enabled LLM agents, where sequences of individually benign tool calls combine to produce harmful operations that only become apparent at the final step.
