Advanced Micro Devices Inc. (AMD), the world’s second-largest maker of computer processors, is investigating claims that a cybercriminal group has stolen a trove of confidential company data in a recent hack.

The chipmaker released a statement saying "We are aware of a cybercriminal organisation claiming to be in possession of stolen AMD data. We are working closely with law enforcement officials and a third-party hosting partner to investigate the claim and the significance of the data."

The claims come from a hacker known as "Intelbroker" who posted on the "BreachForums" website, alleging they had breached AMD's systems in June 2024. According to the post, the stolen data includes future product details, customer databases, financial records, source code, employee information and other sensitive material.

Intelbroker has developed a notorious reputation for high-profile hacks, with past alleged targets including Europol, Facebook, Home Depot, and a major data breach at T-Mobile that US authorities attribute to them. The hacker is now selling the purported AMD data exclusively for the Monero cryptocurrency.

"The alleged breach also includes the complete database of AMD employees, which contains sensitive personal information such as user IDs, job functions, email addresses, employment status and business phone numbers," cybersecurity firm Hackread reported after viewing Intelbroker's post.

If confirmed, the implications would be significant for the semiconductor giant based, with leaked data including product roadmaps that could undermine AMD's competitive edge, while employee data exposure risks identity theft.

"We take data security incredibly seriously and are actively investigating," an AMD spokesperson told the BBC, neither confirming nor denying the breach directly. "Appropriate authorities have been notified."
