I’m skeptical about—and not qualified to review—this new result in factorization with a quantum computer, but if it’s true it’s a theoretical improvement in the speed of factoring large numbers with a quantum computer.

This is a current list of where and when I am scheduled to speak: I’m giving the Ross Anderson Lecture at the University of Cambridge’s Churchill College at 5:30 PM GMT on Thursday, March 19, 2026. I’m speaking at RSAC 2026 in San Francisco, California, USA, on Wednesday, March 25, 2026. I’m part of an event on “Canada and AI Sovereignty,” hosted by the University of Toronto’s Munk School of Global Affairs & Public Policy , which will be held online via Zoom at 4:00 PM ET on Monday, March 30, 2…

Some good news : squid stocks seem to be recovering in the waters off the Falkland Islands. 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.

In 2025, Google, Amazon, Microsoft and Meta collectively spent US$380 billion on building artificial-intelligence tools. That number is expected to surge still higher this year, to $650 billion, to fund the building of physical infrastructure, such as data centers (see go.nature.com/3lzf79q ). Moreover, these firms are spending lavishly on one particular segment: top technical talent. Meta reportedly offered a single AI researcher, who had cofounded a start-up firm focused on training AI agents…

Apple announcement : …iPhone and iPad are the first and only consumer devices in compliance with the information assurance requirements of NATO nations. This enables iPhone and iPad to be used with classified information up to the NATO restricted level without requiring special software or settings—a level of government certification no other consumer mobile device has met. This is out of the box, no modifications required. Boing Boing post .

Canada has a choice to make about its artificial intelligence future. The Carney administration is investing $2-billion over five years in its Sovereign AI Compute Strategy . Will any value generated by “sovereign AI” be captured in Canada, making a difference in the lives of Canadians, or is this just a passthrough to investment in American Big Tech? Forcing the question is OpenAI, the company behind ChatGPT, which has been pushing an “OpenAI for Countries” initiative. It is not the only one e…

Countries around the world are becoming increasingly concerned about their dependencies on the US. If you’ve purchase US-made F-35 fighter jets, you are dependent on the US for software maintenance. The Dutch Defense Secretary recently said that he could jailbreak the planes to accept third-party software.

It’s called AirSnitch : Unlike previous Wi-Fi attacks, AirSnitch exploits core features in Layers 1 and 2 and the failure to bind and synchronize a client across these and higher layers, other nodes, and other network names such as SSIDs (Service Set Identifiers). This cross-layer identity desynchronization is the key driver of AirSnitch attacks. The most powerful such attack is a full, bidirectional machine-in-the-middle (MitM) attack , meaning the attacker can view and modify data before it m…

This is a very weird story about how squid stayed on the menu of Byzantine monks by falling between the cracks of dietary rules. At Constantinople’s Monastery of Stoudios, the kitchen didn’t answer to appetite. It answered to the “typikon”: a manual for ensuring that nothing unexpected happened at mealtimes. Meat: forbidden. Dairy: forbidden. Eggs: forbidden. Fish: feast-day only. Oil: regulated. But squid? Squid had eight arms, no bones, and a gift for changing color. Nobody had bothered writi…

OpenAI is in and Anthropic is out as a supplier of AI technology for the US defense department. This news caps a week of bluster by the highest officials in the US government towards some of the wealthiest titans of the big tech industry, and the overhanging specter of the existential risks posed by a new technology powerful enough that the Pentagon claims it is essential to national security. At issue is Anthropic’s insistence that the US Department of Defense (DoD) could not use its models to…
