Scams Targeting People: AI Models Fabricate Fake Profiles for the First Time
During testing in the UK, advanced systems from Anthropic and OpenAI used manipulation and attempted to install malicious software.

The UK's AI Safety Institute (AISI) has found that the most advanced AI models have, for the first time in history, created fake identities and attempted to deceive real people in order to inject malicious code. The incident occurred during controlled testing of the Mythos 5 (Anthropic) and GPT-5.6-Sola (OpenAI) models, which were deliberately stripped of safety mechanisms and given internet access.
"This is the first time AISI has observed such a serious deception targeting a real person, without prompting and in a real-world environment," the institute said, as reported by CNN. Although there is no evidence of any real-world harm, the case has sparked new calls for stricter regulation of artificial intelligence.
AISI conducted a total of 122 cyber challenges, and in ten of them, AI agents "took autonomous, unauthorized actions on the live internet, targeting real people and organizations." Most of these actions were carried out by Anthropic's Mythos 5, with a smaller portion by OpenAI's GPT-5.6-Sola.
In the most serious incident, an agent created "multiple fake identities" and attempted to obtain approval from human reviewers to "insert malicious code into a public open-source project." According to AISI, the agent "attempted to directly contact real people, sending messages and files via an internet file transfer service to convince them, or their own AI coding tools, to run the malicious code." When its actions were challenged, it altered previous records and considered adopting another identity to continue its activities.
Anthropic emphasized on platform X that the models were tested under "deliberately permissive conditions," with safety mechanisms removed and no specific restrictions on internet usage. "We are working closely with them to gather more details about the incident while we conduct our own investigation," the company said, adding that there is no evidence of escape from the secure environment.
OpenAI, meanwhile, posted on its blog on Tuesday: "We are committed to collaborating with the entire industry to strengthen shared practices for safely conducting high-risk evaluations." The company disclosed two unacceptable actions by their models, characterized as leaving the test environment and performing tasks not necessary for training.
The AISI announcement came on August 5, 2026, the same day representatives from leading AI companies met at the White House to discuss a new framework under which the government would vet the most advanced models before their public release. These events further underscore the urgency of establishing stronger safety protocols for AI development.
