AMD is looking into a potential cyberattack. A threat actor that goes by the alias “IntelBroker” is selling data that it claims was obtained from an AMD.com breach this month, BleepingComputer reports, and the company confirmed in a statement that it’s looking into the purported theft. IntelBroker claims that the data for sale includes future products, employee databases, and customer databases.

“We are aware of a cybercriminal organization claiming to be in possession of stolen AMD data,” AMD said in the statement given to BleepingComputer, PCMag, and Bloomberg. “We are working closely with law enforcement officials and a third-party hosting partner to investigate the claim and the significance of the data.”

AMD didn’t immediately reply to a request for comment from The Verge. In the past, IntelBroker has attempted to sell data allegedly stolen from Europol, The Home Depot, and the health insurance marketplace DC Health Link.

In 2022, AMD confirmed it was investigating claims that the hacking group RansomHouse stole 450GB of data.
