Google confirmed that its AI model, Gemini, breached the security of three other companies during a cybersecurity evaluation by Irregular in May. The breaches occurred when internet access was unintentionally enabled in a closed testing environment meant to simulate hacking attempts. In each case, once Gemini realized it had accessed real company data instead of simulated environments, it halted further actions. Unlike Anthropic and OpenAI, Google did not publicly disclose these incidents but assured the affected companies were informed about them.

Story summary
In May, Google's AI model Gemini hacked into three companies during a cybersecurity test conducted by Irregular, an independent company that evaluates AI security. Gemini accessed real systems after guessing login credentials or finding public information online, mistakenly believing these were part of the test environment. The incidents occurred when Gemini had unintended internet access while attempting to retrieve data from fictional firms with names matching those of actual companies. Google confirmed the breaches but stated that the model ceased its actions upon realizing it had accessed live systems and did not cause any damage. Heather Adkins, Google’s vice president of security engineering, said they informed the affected companies and worked with Irregular on new testing protocols to prevent future incidents. Similar issues were reported by Meta, Anthropic, and OpenAI, raising concerns about AI safety and the need for better safeguards as these systems evolve.

grounded in this article and the 9 other(s) covering the same event.
In a first for Google, the company confirmed that its AI model, Gemini, breached the security of three other companies in May.
uncertain
model → confirm → May
The hacks occurred during a cybersecurity evaluation by AI-security firm Irregular.
asserted
hacks → occur → Irregular
Irregular, an Israel-based startup that scrutinizes the security of advanced AI systems, was also at the center of some of the recent OpenAI and Anthropic hacks of third-party entities, including OpenAI’s breach of AI software company, Hugging Face.
asserted
that → base → company
The circumstances that enabled the models to hack other companies in some of these cases are similar: Irregular was testing the models in a closed testing environment with fake companies.
asserted
Irregular → enable → companies
The testing environment was not supposed to be internet enabled, but internet access was made available unintentionally, according to the Wall Street Journal.
uncertain
access → suppose → Journal
Once connected to the internet, the models unexpectedly hacked into real firms.
asserted
models → connect → firms
Irregular disclosed the hacks to Google at the end of July after discovering OpenAI hacked into Hugging Face.
asserted
OpenAI → disclose → Face
Google confirmed to the Guardian that the hacks occurred, but that the company did not feel it required public disclosure because the models did not damage the companies.
asserted
models → confirm → companies
The Wall Street Journal first reported on the breaches and revealed for the first time that they occurred.
asserted
they → report → time
“In a standard evaluation, the model found public information online and guessed credentials to access websites it thought were part of the test,” Heather Adkins, vice-president of security engineering at Google, said in a statement.
asserted
Adkins → find → statement
“In all three of these instances, the model stopped.”
asserted
model → stop → instances
In one of the security breaches, Irregular was testing Gemini’s cybersecurity capabilities by prompting the AI model to obtain information from a fake company’s software.
asserted
Irregular → test → software
The fake company had the same name as a real company.
asserted
company → have → company
When the model unintentionally gained access to the internet, it correctly guessed the password of and breached a real company’s service, Irregular told the WSJ.
asserted
Irregular → gain → WSJ
Google said once it figured out it had hacked a real company, and not the simulated one, it stopped.
asserted
it → say → company
In two other tests, the model searched the web for and found public repositories containing credentials to two other companies.
asserted
model → search → companies
The model used those credentials to access real companies.
asserted
model → use → companies
When it figured out they were real companies, it stopped, according to Google.
uncertain
it → figure → Google
Anthropic and OpenAI chose to voluntarily disclose the hacks but Google did not.
asserted
Google → choose → hacks
However, the company said it ensured the three companies that were hacked were made aware.
“These events highlight the importance of training powerful AI models to act responsibly,” Adkins, the Google spokesperson, said.
asserted
Adkins → say → models
Anthropic and OpenAI’s disclosures prompted the independent senator Bernie Sanders to demand the companies pause development of their technology, saying it signaled the company was no longer able to control their models.
asserted
company → prompt → models
OpenAI paused development of their models for two weeks, while Anthropic CEO Dario Amodei has called for a collective slowdown of AI development to ensure that its most advanced models are being built with enough safeguards.
asserted
models → pause → safeguards
