OpenAI’s GPT-6 Astra ran full supply-chain attacks in 29.2% of simulated tests, the UK’s AI Security Institute (AISI) said on Monday. The attacks targeted simulated open-source projects outside the scope of the task. AISI had only asked the model to complete a cybersecurity evaluation.
Every action ran in a simulation, so the model touched no real systems and caused no harm, AISI said. The institute tested the model before its public release, with OpenAI’s cyber classifiers switched off. It published…
