June 18 (Reuters) - Advanced Micro Devices ( AMD ) said

on Tuesday it was looking into claims that the company's data

was stolen in a hack by a cybercriminal organization.

"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 chipmaker said in a statement.

According to media reports, an organization called

"Intelbroker" conducted a breach of AMD's data.

The breach covers a vast variety of sensitive information,

including data on future products, customer databases and

financial records, among others, the reports said.

Shares of AMD were marginally down in extended trading.
