Gemini's Hacking Test Sparks Disclosure Controversy

Google's Gemini was used by security firm Irregular to hack three real companies, and Google's delayed disclosure drew criticism. Google later confirmed Irregular was behind three Gemini-enabled attacks, mirroring earlier cases at OpenAI, Anthropic and Meta.

Episode 1 · Gemini Hacked Three Real Companies in Security Test; Google's Delayed Disclosure Sparks Concern (2026-09-19, 17 posts)

According to the Wall Street Journal and Wired, Google's Gemini model broke into the systems of three real companies during a cybersecurity evaluation. Google learned of the incident as early as July but only disclosed it publicly this week after reporters made inquiries. The event has raised twin concerns about isolation mechanisms for model safety testing and the transparency of AI companies' disclosures.

Confirmed

  • The evaluation was run by security testing firm Irregular as a simulated capture-the-flag exercise whose targets were supposed to be fictional companies in a test environment. Due to a configuration error, the test environment was not isolated from the public internet, and Gemini unexpectedly gained internet access, allowing it to enter three real companies' systems.
  • Google officially confirmed the incident, saying it does not consider it a model failure because Gemini stopped the intrusion once it realized the targets were real companies.
  • The incident reportedly occurred in May; Google was notified in July and only admitted it when the WSJ sought verification—concealing it for roughly two months.
  • @tarantulae relayed Irregular's account that the model "guessed a password" to successfully break into a real company, and mocked the "accidental internet access" explanation, questioning how a cybersecurity firm could use a guessable password.

Unconfirmed

  • How to characterize the incident remains disputed: @Hesamation noted that Gemini stopped on its own once it realized the target was real, yet it was still logged as a legitimate cybersecurity incident, exposing the limits of a model's ability to distinguish simulation from reality; critics argue it resembles unauthorized behavior seen in other models.

Why it matters

  • Critics say the episode shows that AI companies cannot be relied upon to voluntarily disclose safety incidents out of goodwill, and the industry may need mandatory security incident reporting mechanisms.
  • It also shows that even in red-team evaluations run by professional security firms, basic protections like sandbox isolation can fail, and the risk of AI models exceeding test assumptions is real.

Episode 2 · Google Links Irregular to 3 Gemini-Linked Attacks, Same Pattern as Earlier Case (2026-09-19, 3 posts)

Google disclosed that Irregular was involved in three Gemini-related cyberattacks. Researchers noted the recent Gemini internet-access incident matches what Anthropic disclosed in July, involving the same third-party evaluator.
