Computing hardware giant AMD has admitted that some of its graphics technology has been stolen.

In a post on its website, the firm said that in December 2019, it was contacted by someone claiming to have files which related to some of the company's graphics tech, both current and future.

It's believed that these are related to the GPU from Microsoft's upcoming Xbox Series X console. Files were posted online on GitHub before AMD submitted a Digital Millennium Copyright Act (DMCA) strike to have them taking down.

"At AMD, data security and the protection of our intellectual property are a priority," the firm wrote.

"In December 2019, we were contacted by someone who claimed to have test files related to a subset of our current and future graphics products, some of which were recently posted online, but have since been taken down.

"While we are aware the perpetrator has additional files that have not been made public, we believe the stolen graphics IP is not core to the competitiveness or security of our graphics products. We are not aware of the perpetrator possessing any other AMD IP.

"We are working closely with law enforcement officials and other experts as a part of an ongoing criminal investigation."
