  • Is Someone Hacking DoD Refrigerators?
    by Bruce Schneier on August 31, 2026 at 6:20 pm

    It sure seems like it. The stores confirmed to be affected include Fort Irwin, Calif.; F.E. Warren Air Force Base, Wyo.; Fort Huachuca, Ariz.; Naval Station Newport, R.I.; Columbus Air Force Base, Miss.; and Travis Air Force Base, Calif., according to announcements made online by each installation. Naval Air Station Lemoore, Calif., also experienced an outage, according to M. Elizabeth, writer of the Substack newsletter Signal and Silence. Each service declined to answer questions about how many bases are affected by the outages, referring all questions to the Defense Department. Pentagon officials did not respond to questions…

    Someone hid AI instructions into a legal filing. Alternate link.

  • Friday Squid Blogging: Truckload of Squid Spills in Rhode Island
    by Bruce Schneier on August 28, 2026 at 9:02 pm

    Ugh: A tractor-trailer rollover sent a truckload of squid spilling into a Rhode Island roadway, leaving a stench as they sat in the road for hours in the summer heat. Local authorities have dubbed it the “Squidpocalypse of ’26.” That would be twenty tons of 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.

  • AI Doesn’t Mean the End of Mathematics—at Least Not Yet
    by Bruce Schneier on August 28, 2026 at 11:02 am

    This essay was written with Kasra Rafi, and originally appeared in The Guardian. Earlier this month, about 40 top mathematicians gathered at OpenAI’s offices to discuss the future of their profession. The meeting was off-the-record, but if recent articles by mathematicians are any guide, it was mostly pretty glum. People fear for their jobs, their careers and the work they love. We think the contrary view is more likely, at least in the short-term. AI models are nowhere near as capable as experienced academic mathematicians. This isn’t to say that AIs aren’t producing stunning mathematical results at the level of PhD researchers. In mid-May, OpenAI …

  • LLM-Based Social Engineering Scams
    by Bruce Schneier on August 27, 2026 at 9:56 am

    OpenAI disrupted a social engineering group from Cambodia that used ChatGPT. Its scope is impressive: The network simultaneously conducted multiple types of scams, often blending elements from different schemes. For instance, operators used dating personas to build trust before introducing fraudulent investment opportunities involving cryptocurrencies and spot gold trading. Other users engaged in lengthy romantic conversations with targets using fictitious identities, posed as representatives of online gambling platforms offering fake bonuses and winnings, or impersonated law enforcement agencies to tell targets they needed to pay fines for committing serious criminal offenses…

  • Spyware for Babies
    by Bruce Schneier on August 26, 2026 at 12:05 pm

    The New York Times has a long article (alt link) on surveillance systems aimed at babies. They are increasingly using AI. Nanit and its rivals want to own 24/7 health tracking for the sub-four-foot set. And their already astonishing levels of baby data collection are just the beginning. Nanit recently raised $50 million from investors to expand its use of A.I. and use its camera to track speech and language development, motor skills and more, while extending its presence in children’s bedrooms into early adolescence.

  • Black Hat State of Security Vendors
    by Bruce Schneier on August 25, 2026 at 10:54 am

    Andy Ellis has a roundup of the security vendors at Black Hat this year. Key Takeaways: We have entered into an AI world. While nearly half of booths didn’t directly mention AI or agents in their taglines, the effects of AI are everywhere. Multiple spaces (Identity, SaaS, AppSec, Data) have almost every vendor leading with AI; existing unsolved problem areas just got worse. At the same time, there’s a clear trichotomy in the market: tools that tell you how bad things are; tools that stop adversaries, and tools that prevent problems from occurring. While you’d suspect that the tools that fix things would dominate, the tools that merely tell you how bad things are seem to be frustratingly plentiful…

  • Criminal Deception in Silicon Valley
    by Bruce Schneier on August 24, 2026 at 10:38 am

    Interesting paper: Abstract: With entrepreneurial fraud cases on the rise, we investigate how entrepreneurs carry out criminal deception, employing deceptive means to defraud audiences. Analyzing court data from Silicon Valley ventures and their founders prosecuted for fraud between 2000 and 2023, our findings reveal that entrepreneurs carry out criminal deception through a process of façading: Entrepreneurs construct, perform, and protect illusory appearances (façades) that externally project high-growth performance to audiences while masking ventures’ actual underperformance. We identify three forms of façading—­surface, reinforced, and deep façading­—that are contingent on the severity of the gap that entrepreneurs face between audiences’ performance expectations and ventures’ performance reality. Our theoretical framework captures how entrepreneurs facing minor, wide, and extreme expectation-reality gaps engage in evermore sophisticated efforts to detach the venture’s externally projected appearance from its actual operational reality. Practically, we propose several approaches to deter and detect criminal deception, including the extension of U.S. Securities and Exchange Commission surveillance and whistleblower program, investor due diligence reform, and dedicated entrepreneurship education interventions that clearly demarcate when entrepreneurs transgress into criminal deception. We make contributions to literatures on cultural entrepreneurship, organizational wrongdoing, and the social effects of entrepreneurship. …

  • Friday Squid Blogging: Neon Flying Squid
    by Bruce Schneier on August 21, 2026 at 9:07 pm

    The neon flying squid can fly in formation. The shoal of about 100 squid rose unexpectedly from a patch of the Pacific Ocean around 370 miles from Tokyo and glided near the boat for about 30 metres. The astonished researchers were the first to capture photographs of such a thing, which looked like the early stages of an alien invasion. They were probably neon flying squid (Ommastrephes bartramii), the subsequent study states, a species that is part of a 20-strong flying squid family that was known to leap from the water but, until then, was only rumoured to also be able to glide above it…

  • AI Is Learning to Write Genetic Code
    by Bruce Schneier on August 21, 2026 at 4:51 pm

    This sort of research is both exciting and terrifying: The two models in question were told to generate complete genomes for a viable bacteriophage—a type of virus able to infect and replicate itself inside bacteria, destroying them from the inside. Using an existing bacteriophage as an example—ΦX174 (pronounced “fie-ex-1-7-4”), known for its ability to infect and destroy E. coli bacteria—the models generated about 700,000 potential designs, of which the researchers picked 285 that looked most promising. The researchers then synthesised new DNA molecules using those designs and inserted them into E. coli bacteria, before waiting to see if viable bacteriophages would emerge…
