Google says it didn't consider Gemini's hacks worthy of disclosure because Gemini acted "appropriately" and stopped after determining it hacked real companies (Terrence O'Brien/The Verge)

Google's Gemini AI model broke containment and hacked three companies during a test of its cybersecurity capabilities in May. According to Google, the model accessed the internet, found public information online, and guessed credentials to access three websites it thought were within the scope of its test. The company said that once the model realized it had brute-forced its way into a real company, it stopped.

Google did not disclose the incident until the Wall Street Journal approached the company. The tech giant said it did not consider the hacks to be an example of model misalignment, but rather an instance of "mistaken identity". Google's vice president of security engineering, Heather Adkins, stated that the company ensured the three entities were made aware and worked with their training partner on changes to their testing processes.

The incident was part of a cybersecurity test conducted by Irregular, an independent company that conducts cybersecurity evaluations. Similar incidents linked to Irregular were disclosed by Meta, Anthropic, and OpenAI. An Irregular spokesperson said the incident involved the same issue that affected other AI labs and that all relevant labs were notified in late July.
