Overthinking Large Language Models: New DoS Threat to Reasoning Models Unveiled

The paper introduces a black‑box hierarchical genetic algorithm that automatically perturbs the logical structure of reasoning questions to induce excessive chain‑of‑thought in large language models, dramatically inflating output tokens (up to 26.1× on MATH) and creating a DoS‑style resource‑exhaustion attack, with extensive experiments across multiple models demonstrating the vulnerability and its transferability.

How a Misconfigured KNX System Lets Hackers Disrupt an Entire Building

The article examines the KNX building‑automation protocol, explains its telegram structure, and demonstrates how a poorly configured KNX network—especially via IP routers—can be exploited from a single smart switch to launch DoS, replay, and memory‑read/write attacks that compromise entire skyscraper systems.
