The Department of Homeland Security said it has no reason to question denials by U.S. technology companies of a report that Chinese spies had used a microchip to hack into American computer networks.
“At this time we have no reason to doubt the statements from the companies named in the story,” Tyler Houlton, press secretary for the Department of Homeland Security, said in an emailed statement late Saturday. The companies, including Amazon.com Inc. and Apple Inc., have denied that their systems were compromised.
