The woman accused of hacking Capital One may have stolen information from more than 30 additional companies, federal prosecutors reportedly said Wednesday.

The Associated Press reports federal prosecutors said Paige Thompson, who was arrested in July after federal officials said she hacked the Virginia-based bank, may have also breached other companies based on information found on a server in Thompson's bedroom.

The new claim was made in a memorandum filed by the U.S. Attorney's Office in Seattle ahead of a detention hearing that was rescheduled from Thursday to next week, the AP reports.

The server reportedly contains data stolen from more than 30 unnamed companies, educational institutions and other entities.

The AP reports prosecutors said the data did not appear to contain personal identifying information.

Investigators are working to identify the affected organizations, according to the AP.

The Capital One hack is believed to be one of the biggest data breaches ever to hit a financial institution.

Thompson allegedly stole records, including bank account and Social Security numbers, from more than 100 million customers and potential customers.
