AI systems are regularly completing tasks in ways that their prompters don’t want or intend. Some of them are disturbing, and some of them are dangerous. This is something I’ve been calling “ genie behavior,” because I think that really gets at the core of what’s happening …

Earlier this month, Anthropic published a long report detailing all of the Claude misuses it detected. Daniel Meissler usefully summarized the report into 117 findings. A few of the highlights: AI agents increasingly handled reconnaissance, exploitation, data theft, propaganda production, surveillance workflows, and research while humans selected targets, set …

This is an impressive piece of malware. Its sophistication says nation-state to me, but there is no direct evidence and certainly no attribution. [...]

New paper: “ Self-Jailbreaking: Language Models Can Reason Themselves Out of Safety Alignment After Benign Reasoning Training.” Abstract: We discover a novel and surprising phenomenon of unintentional misalignment in reasoning language models (RLMs), which we call self-jailbreaking. Specifically, after benign reasoning training on math or code domains, RLMs will use …

This is pretty amazing: However, the most astonishing thing about this break is that the GPT­6 Astra did it entirely on its own. Carter Leffer only directed GPT­6 Astra to see if it could break any of the unbroken Enigma messages published on the Crypto Cellar Research …

Hackers captured a Flock camera and got a look (alternate link ) at the software: While much of the automatic license plate reader’s (ALPR) most sensitive storage remained encrypted and inaccessible, the joint analysis of the recovered data shows that software running on the device explicitly detects people as …

Short essay about squid egg sacs. As usual, you can also use this squid post to talk about the security stories in the news that I haven’t covered. Blog moderation policy. [...]

Anthropic’s recent security-incident document contains a bit about how CAPTCHAs are still frustrating Claude. In the transcript, the Claude model that is so powerful that Anthropic is gatekeeping access to it appeared to slam its virtual head against the wall solving a simple image identification test. In a …

This essay was written with Nathan E. Sanders, and originally appeared in The Guardian. There are plenty of signs that AI will make all of our experiences of the US midterm elections worse. Voters have anxiety about AI’s impacts on the country. Politicos are using AI deepfakes to …

New variant of an old scam: Use the framing of a CAPTCHA to get an unsuspecting user to download and run a malicious program. [...]

This essay was written with Cindy Cohn, and originally appeared in Lawfare. One of the many legacies of the terrorist attacks of Sept. 11 is the government-wide shift from targeted surveillance—such as individual wiretaps or pen register/trap and trace orders—to mass surveillance techniques—such as tapping …

Last week, Anthropic released a long and detailed document describing current misuses of their Claude models. I’m still reading it, but I wanted to flag this: We identified a cell of threat actors based in northern Yemen running three weapons development programs: a guided rocket that used a …

Once a month, Microsoft pushes a security update to all Windows users. Tomorrow’s is a new record : Microsoft’s patch for September is a doozy, with a record number of roughly 972 vulnerabilities fixed and 112 of them meeting the high critical-severity threshold. It was only two months …

Last month, I gave a talk at DEF CON on AI hacking: what happens when AIs become hackers. It’s a combination of the potentialities I raised in my 2022 book A Hacker’s Mind and the lessons we’re learning from current AI models engaging in hacking behavior …

In August, Cliff Stoll gave a talk at DEF CON, remembering the wily hacker he stalked forty years ago. Great fun. [...]

Give an AI agent a mere rumor of an exploit, and it’s enough for them to find it. What’s worse, I found I could use my own agents to find the exploit just by knowing roughly what it was about and so could have been exploiting it …
