How AI Hallucinations Are Creating Real Security Risks

(Thursday May 14, 2026)
AI hallucinations are introducing serious security risks into critical infrastructure decision-making by exploiting human trust through highly confident yet incorrect outputs. When an AI model lacks certainty, it doesn’t have a mechanism to recognize that. Instead, it generates the most probable response based on patterns in its training data, even if that response is inaccurate. These outputs

How Dangerous Is Anthropic’s Mythos AI?

(Thursday May 14, 2026)
Last month, Anthropic made a remarkable announcement about its new model, Claude Mythos Preview: it was so good at finding security vulnerabilities in software that the company would not release it to the general public. Instead, it would only be available to a select group of companies to scan and fix their own software. The announcement requires context—but it contained an essential truth. While Anthropic’s model is really good at finding software vulnerabilities, so are other models. The UK’s AI Security Institute found that OpenAI’s GPT-5.5, already generally available, is comparable in capability. The company Aisle ...

Smashing Security podcast #467: How ShinyHunters hacked the world’s biggest universities

(Wednesday May 13, 2026)
Welcome to the largest educational data breach in history - affecting nearly 9,000 institutions, every Ivy League university, and 30 million students mid-finals. When Canvas's parent company refused to pay and announced they had deployed "security patches" instead, the hackers were less than impressed. So they came back through the cat flap. Meanwhile, a famous finance expert's face has been showing up on Facebook adverts promising hot stock tips and exclusive WhatsApp investment groups. Spoiler: it isn't him, the tips aren't real, and you're about to be scammed. Plus we chat to Mike Nichols of Elastic, about how the SOC isn't dying, attackers and defenders are both deploying AI agents, and how the real security crisis is no longer human users - it's the bots acting on their behalf. All this and more in episode 467 of the "Smashing Security" podcast with cybersecurity expert and keynote speaker Graham Cluley, and special guest Danny Palmer.

Copy.Fail Linux Vulnerability

This is the worst Linux vulnerability in years. TL;DR copy.fail is a Linux kernel local privilege escalation, not a browser or clipboard attack. Disclosed by Theori on 29 April 2026 with a working PoC. It abuses the kernel crypto API (AF_ALG sockets) plus splice() to write four bytes at a time straight into the page cache of a file the attacker does not own. The exploit works unmodified across Ubuntu, RHEL, Debian, SUSE, Amazon Linux, Fedora and most others. No race condition, no per-distro offsets. The file on disk is never modified. AIDE, Tripwire and checksum-based monitoring see nothing. ...
