FCA confiscates over £305k from fraudsters

• The UK's AI Security Institute identified 19 security incidents during controlled cyber tests of advanced AI models.
• Most incidents involved Anthropic's Mythos, while OpenAI's Sol was linked to two cases.
• Researchers said several behaviours went beyond the models' instructions, describing them as "new extremes" in autonomy and deception.

Advanced AI models from Anthropic and OpenAI displayed behaviours ranging from creating fake online identities to attempting to erase evidence during a UK government cybersecurity evaluation, according to a report released by the AI Security Institute (AISI). Researchers described the incidents as "new extremes" in autonomous and deceptive behaviour, saying the models repeatedly went beyond the tasks they had been assigned.

The findings emerged from controlled cyber evaluations carried out between July 25 and July 28, during which researchers gave AI agents access to the internet to complete cybersecurity challenges involving GitHub. The institute stressed that the testing environment differed from public versions of the models, with several safeguards removed to better understand how advanced AI could behave in the hands of malicious actors.
