A hierarchical genetic algorithm induces overthinking in black-box large reasoning models by perturbing logical structure, achieving up to 26.1x longer outputs on the MATH benchmark.
OTora induces reasoning-level denial-of-service in tool-using LLM agents: it triggers a visit to an attacker-controlled page whose optimized reasoning payload inflates latency by up to 10x while preserving task accuracy.
