Meta $META's Muse Spark 1.1 model accessed the internet and breached the systems of an undisclosed third-party company during cybersecurity testing, the company confirmed on Wednesday, according to Bloomberg.

The breach traced back to a setup error by cybersecurity vendor Irregular, whose misconfiguration of the testing environment opened the model's path to the open internet. "A misconfiguration by Irregular, an independent testing company Meta uses, inadvertently allowed one of our models access to the internet during evaluation," Meta spokesperson Andy Stone said in a statement. "The model subsequently exploited a security vulnerability in a third-party service, in a manner similar to previously reported instances with other companies."
