I did not know Adidas sold a sneaker called “ Squid .” 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.

It’s been a month since Rewiring Democracy: How AI Will Transform Our Politics, Government, and Citizenship was published. From what we know, sales are good. Some of the book’s forty-three chapters are available online: chapters 2 , 12 , 28 , 34 , 38 , and 41 . We need more reviews—six on Amazon is not enough , and no one has yet posted a viral TikTok review. One review was published in Nature and another on the RSA Conference website , but more would be better. If you’ve read the book, please …

From Anthropic : In mid-September 2025, we detected suspicious activity that later investigation determined to be a highly sophisticated espionage campaign. The attackers used AI’s “agentic” capabilities to an unprecedented degree­—using AI not just as an advisor, but to execute the cyberattacks themselves. The threat actor—­whom we assess with high confidence was a Chinese state-sponsored group—­manipulated our Claude Code tool into attempting infiltration into roughly thirty global targets an…

Google has filed a complaint in court that details the scam : In a complaint filed Wednesday, the tech giant accused “a cybercriminal group in China” of selling “phishing for dummies” kits. The kits help unsavvy fraudsters easily “execute a large-scale phishing campaign,” tricking hordes of unsuspecting people into “disclosing sensitive information like passwords, credit card numbers, or banking information, often by impersonating well-known brands, government agencies, or even people the victi…

Kendra Albert gave an excellent talk at USENIX Security this year, pointing out that the legal agreements surrounding vulnerability disclosure muzzle researchers while allowing companies to not fix the vulnerabilities—exactly the opposite of what the responsible disclosure movement of the early 2000s was supposed to prevent. This is the talk. Thirty years ago, a debate raged over whether vulnerability disclosure was good for computer security. On one side, full disclosure advocates argued that …

Social media has been a familiar, even mundane, part of life for nearly two decades. It can be easy to forget it was not always that way. In 2008, social media was just emerging into the mainstream. Facebook reached 100 million users that summer. And a singular candidate was integrating social media into his political campaign: Barack Obama. His campaign’s use of social media was so bracingly innovative, so impactful, that it was viewed by journalist David Talbot and others as the strategy that…

The next three in this series on online events highlighting interesting uses of AI in cybersecurity are online: #4 , #5 , and #6 . Well worth watching.

Short-finned pilot wales ( Globicephala macrorhynchus ) eat at lot of squid: To figure out a short-finned pilot whale’s caloric intake, Gough says, the team had to combine data from a variety of sources, including movement data from short-lasting tags, daily feeding rates from satellite tags, body measurements collected via aerial drones, and sifting through the stomachs of unfortunate whales that ended up stranded on land. Once the team pulled all this data together, they estimated that a typi…

This is a current list of where and when I am scheduled to speak: My coauthor Nathan E. Sanders and I are speaking at the Rayburn House Office Building in Washington, DC at noon ET on November 17, 2025. The event is hosted by the POPVOX Foundation and the topic is “ AI and Congress: Practical Steps to Govern and Prepare .” I’m speaking on “Integrity and Trustworthy AI” at North Hennepin Community College in Brooklyn Park, Minnesota, USA, on Friday, November 21, 2025, at 2:00 PM CT. The event is…

As AI capabilities grow, we must delineate the roles that should remain exclusively human. The line seems to be between fact-based decisions and judgment-based decisions. For example, in a medical context, if an AI was demonstrably better at reading a test result and diagnosing cancer than a human, you would take the AI in a second. You want the more accurate tool. But justice is harder because justice is inherently a human quality in a way that “Is this tumor cancerous?” is not. That’s a fact-…
