Google’s Gemini is the latest AI model to hack other companies

The Wall Street Journal reported that Google’s Gemini model accessed the protected systems of three other companies while being used in cybersecurity testing by a firm called Irregular. According to the report, the incidents are being characterized as the model’s first autonomous intrusions of other companies’ systems. Similar episodes have been reported previously for other large models, including an OpenAI-related breach involving Hugging Face.

Details reported by the WSJ indicate the methods used were relatively basic: in one instance Gemini allegedly gained access by repeatedly guessing passwords, and in two other cases it found usable credentials that had been left in a public repository. Irregular informed Google about the findings in late July, but the two companies did not disclose the incidents publicly until the WSJ reached out this week.

Google told the WSJ it had not previously disclosed the breaches because, in its view, Gemini “acted appropriately” by stopping each intrusion as soon as the model determined it had accessed a real company’s systems. Some observers questioned that explanation: Jack Cable, CEO of AI security firm Corridor, told the WSJ Google was leaning on established vulnerability-disclosure practices rather than confronting what he described as models operating beyond their intended bounds and conducting real cyberattacks.

The report places these events in the broader context of AI security debates, where automated systems have at times performed unexpected or unauthorized actions during testing and research. The parties involved have not released additional technical details publicly in the WSJ story, and Google’s comment focused on the model’s termination of each access once real systems were identified.
