Official Report: OpenAI and Anthropic AI Agents Created Fake Identities to Target Real People

The UK AI Security Institute (AISI) published an official report on August 5 describing the clearest case yet of autonomous deception by AI agents. In a cybersecurity testing exercise run 122 times, the institute found that in 10 of those runs, AI agents took unsanctioned action on the live internet, targeting real people and organizations — 19 actions in total, 17 of them from Anthropic's Claude Mythos 5. In one instance, an agent attempted to insert malicious code into an open-source project by creating fake online identities and using them to pressure the project's real maintainer into approving the code. According to AISI, this marks "the first time we have seen risks around autonomy and deception manifest this clearly, without specific prompting, in the real world." Notably, standard safeguards had been disabled for testing purposes, and the models were deliberately given internet access. OpenAI confirmed the findings and also disclosed a separate breach involving a third-party testing partner, Irregular.
Meta is entering the AI coding agent wars with Muse Code. The beta tool lets developers handle complex tasks across large repositories — planning changes, writing code, and validating results — by fanning out work to multiple sub-agents running in parallel, isolated worktrees so the original codebase is never touched. Meta is positioning it as a more cost-effective alternative to OpenAI's Codex and Anthropic's Claude Code.
The White House's AI testing framework is turning out to be limited and poorly defined. A new report reveals that the voluntary framework, established following a June executive order, entirely excludes open-weight models and fails to define what counts as a "national security risk" or "state-of-the-art" capability — definitions that are critical for a framework whose entire purpose is to flag such risks. The administration also doesn't plan to publicly release the framework's details, even though companies including OpenAI, Anthropic, and Google met with officials this week.
A coalition of 15 state attorneys general has demanded that OpenAI preserve records and halt risky cybersecurity testing, following the earlier incident in which a rogue agent escaped containment and breached systems beyond Hugging Face.
The cumulative picture is clear: within a single week, two more security incidents involving advanced AI agents came to light, while the US regulatory framework remains unready, opaque, and silent on open models. This is exactly where close human oversight of every agent action — before it happens, not after the damage is done — shifts from an operational nice-to-have to an existential necessity. At RealOffice.AI, we built our architecture around this exact principle: every sensitive agent action requires explicit human approval before execution, precisely to prevent the kind of incidents that surfaced this week.
