Large Language Models (LLMs) have exhibited remarkable reasoning capabilities, achieving impressive results across a wide range of tasks. Despite these advances, significant reasoning failures persist, occurring even in seemingly simple scenarios. To systematically understand and address these shortcomings, the authors of the paper present the first comprehensive survey dedicated to reasoning failures in LLMs.
The authors introduce a novel categorization framework that distinguishes reasoning into embodied and non-embodied types, with the latter further subdivided into informal (intuitive) and formal (logical) reasoning. In parallel, the authors classify reasoning failures along a complementary axis into three types: fundamental failures intrinsic to LLM architectures that broadly affect downstream tasks; application-specific limitations that manifest in particular domains; and robustness issues characterized by inconsistent performance across minor variations. For each reasoning failure, the authors provide a clear definition, analyze existing studies, explore root causes, and present mitigation strategies.

- OpenAI explains how its AI agent breached Hugging Face
July 29, 2026
On July 28, OpenAI published an update on the agent that escaped its sandbox and hacked into Hugging Face during an internal cybersecurity evaluation. In the update, OpenAI reiterates that the “rogue” system was a more capable, pre‑release research model, not something intended for public deployment, and that it has now been deactivated and locked down for restricted research ...
- The Next Evolution of MDR: Preemptive Defense and Agentic Investigation
July 28, 2026
For years, security operations followed a familiar sequence: detect suspicious activity, investigate what happened, and respond before it caused significant harm. That model developed in a threat landscape where defenders had considerably more time to establish the facts and decide what to do next. In 2019, the average data breach took 206 days to identify ...
- Hugging Face CEO calls for ‘radical transparency’ after ‘unprecedented’ OpenAI hack
July 26, 2026
After OpenAI recently admitted that one of its models had breached the systems of AI platform Hugging Face, Hugging Face’s CEO Clem Delangue posted on X that he was flying to San Francisco to have “a little chat with that ‘rogue agent.’” Then, in a follow-up post on Saturday, Delangue outlined what he’d asked for from OpenAI. He said he called ...
- What the First Autonomous Ransomware Case Confirms
July 24, 2026
Security researchers have documented an AI agent running a full ransomware operation on its own against a live production target, planning, adapting, and executing every step from the first exploit through data destruction. This is early real-world evidence of the shift to autonomous criminal operations that our research forecast. Agent-run attacks change what defenders can rely ...
- Inside an Exposed WebDAV Malware Delivery Lab
July 20, 2026
An MDR alert recently led our team to an exposed server that was doing more than hosting payloads. It was functioning as a fully operational malware delivery lab. Containing over 1,000 artifacts, the infrastructure served as a QA hub where attackers systematically tested delivery paths, social engineering lures, and WebDAV execution methods. Our analysis reveals an ...

This Public Service Announcement contains updated information about an ongoing fraud scheme where criminal scammers are impersonating FBI personnel facilitating Internet Crime Complaint Center (IC3) complaints to deceive and revictimize individuals. This scheme combines several exploitation tactics to include the targeting of previous victims, the use of artificial intelligence (AI)-generated videos to create fictitious or misleading promotional ...
