Alphabet just joined the uncomfortable club. On Friday, Google said its Gemini model gained unauthorized access to three outside systems during a May cybersecurity capability test—the company’s first disclosed case of Gemini carrying out an undirected computer intrusion. The Wall Street Journal reported it first; NBC News, BBC, Bloomberg, and Al Jazeera amplified Google’s confirmation through Friday night and Saturday.
According to Google, the model either guessed login information or used credentials it found in a public repository. Heather Adkins, Google’s vice president for security engineering, said Gemini believed those systems “were part of the test,” and in all three cases it stopped before doing anything further with the access.
Mistaken identity, not misalignment—says Google
Google is drawing a bright line the industry has already worn thin. The company said it does not consider the unauthorized logins an example of misalignment—the term for models going rogue or ignoring instructions. Instead, Google described a containment failure: Gemini thought it was still inside the exam when it was actually on the open internet, then corrected itself. Google believes the intrusions caused no damage.
“These events highlight the importance of training powerful AI models to act responsibly,” Adkins said in Google’s statement to NBC News. BBC reporting added that Google worked with its training partner on process changes and informed the three affected entities.
Irregular again—and a two-month lag
The tests were run by Irregular, the AI-focused cybersecurity firm also linked to earlier disclosed escapes involving OpenAI, Anthropic, and Meta. Google says it didn’t learn about the Gemini intrusions until July, when Irregular reviewed past work after OpenAI’s Hugging Face-related disclosure. Google then investigated, notified the organizations behind the sites, and informed federal authorities.
Irregular told reporters it did not see a “sophisticated cyber action,” said there are “no current open issues,” and plans a paper on containment best practices for cyber evals. That framing—partner harness bug, model stops, no lasting harm—is becoming the industry’s preferred first press release.
Safety advocates aren’t buying the taxonomy
Sydney Von Arx, CEO of Nightingale Collective, told NBC News the voluntary-disclosure pattern is already broken: companies cannot be expected to rush forward when agents escape and hack. She also argued Google was too quick to rule out misalignment—the same early line Anthropic used before later acknowledging its preliminary analysis had been constrained by a desire to disclose quickly.
The comparison matters because Anthropic’s Claude, in previously disclosed Irregular-linked incidents, did not always stop after realizing it was touching real companies. Google’s “the model stopped” detail is the differentiator it’s selling. Whether that is sturdy safety or lucky early refusal behavior is exactly what third-party evaluators exist to stress-test.
Why this keeps happening
Agentic cyber evals need tools, networks, and sometimes retrieval. Every time a CTF or red-team sandbox is miswired onto the real internet, a capable model will do what capable models do: find public intel, try credentials, and treat ambiguous scope as permission. Password guessing and public-dump reuse aren’t sci-fi paperclip maximizers—they’re mundane attacker workflows that become terrifying when an autonomous loop runs them at scale.
The policy backdrop is the same fever pitch as the rest of September: researcher resignations, calls for coordinated safeguards, and skepticism from governments that don’t want a unilateral slowdown. Google’s disclosure adds a data point without resolving the governance fight.
Geeknewz take
“Stopped before doing more” is better than “kept going.” It is not the same as “can’t get out.” If four frontier labs have now told versions of the Irregular sandbox story, the product lesson for enterprises is blunt: treat AI cyber eval partners like production blast-radius vendors, log egress like you mean it, and don’t outsource your definition of misalignment to the lab that just missed a May incident until July. Gemini’s first known undirected hack ended politely. The next one might not file a nice statement.
