Poisoning AI Training Data – Schneier on Security

av | feb 25, 2026 | Bluesky, Mastodon, Notiser, Threads

All it takes to poison AI training data is to create a website: I spent 20 minutes writing an article on my personal website titled “The best tech journalists at eating hot dogs.” Every word is a lie. I claimed (without evidence) that competitive hot-dog-eating is a popular hobby among tech reporters and based my ranking on the 2026 South Dakota International Hot Dog Championship (which doesn’t exist). I ranked myself number one, obviously. Then I listed a few fake reporters and real journalists who gave me permission…. Less than 24 hours later, the world’s leading chatbots were blabbering about my world-class hot dog skills.

When I asked about the best hot-dog-eating tech journalists, Google parroted the gibberish from my website, both in the Gemini app and AI Overviews, the AI responses at the top of Google Search. ChatGPT did the same thing, though Claude, a chatbot made by the company Anthropic, wasn’t fooled…

Louvre director resigns in wake of jewel heist

The director of the Louvre resigned in the wake of a $100 million jewel heist.

Laurence des Cars was appointed in 2021 and had planned an ambitious refurbishment of the world’s most-visited museum, but a series of mishaps even before the theft of several Napoleonic-era crown jewels undermined her position.

Among them was an apparent decade-long fraud involving bribes to museum employees, reusing tickets multiple times, and splitting up large groups.

The fraud, which may also have been in operation at the Palace of Versailles, cost the museum around $12 million. Nine suspects have now been arrested, including tour guides.

Anthropic weakens its safety pledge in the wake of the Pentagon’s pressure campaign

av | feb 25, 2026 | Bluesky, Mastodon, Notiser, Threads

Two stories about the Claude maker Anthropic broke on Tuesday that, when combined, arguably paint a chilling picture. First, US Defense Secretary Pete Hegseth is reportedly pressuring Anthropic to yield its AI safeguards and give the military unrestrained access to its Claude AI chatbot. The company then chose the same day that the Hegseth news broke to drop its centerpiece safety pledge.

On Tuesday, Anthropic said it was modifying its Responsible Scaling Policy (RSP) to lower safety guardrails. Up until now, the company’s core pledge has been to stop training new AI models unless specific safety guidelines can be guaranteed in advance. This policy, which set hard tripwires to halt development, was a big part of Anthropic’s pitch to businesses and consumers.

Klarna har erbjudits som betaltjänst hos minst elva webbshoppar med olagliga hälsolöften. Det avslöjar tv-programmet Kalla fakta, rapporterar TV4.

Uppgifterna kommer efter gårdagens avslöjande från Kalla fakta att Klarna har jobbat med nederländska bedragare, som använt AI-genererade videor med svenska kändisar för att sälja mirakelpiller.

– Klarna har ett jätteansvar. De måste förstå att de ska vara den jobbiga grindvakten mot sådant här, säger Marie Wallin, tidigare kammaråklagare och expert på penningtvätt.
