An Apple Inc. information security executive forcefully denied to Congress that any of its hardware was compromised in an alleged 2015 incident described in an Oct. 4 Bloomberg Businessweek report, according to an Oct. 7 report from Reuters.

Apple Vice President for Information Security George Stathakopoulos said in a letter to two congressional committees that the company had found no evidence of the type of attack alleged by the Bloomberg Businessweek report, which claimed Apple and other U.S. technology companies were impacted by a Super Micro Computer Inc. hardware breach in which Chinese spies planted extra chips on server motherboards during manufacturing. All the companies named in the Bloomberg article have denied such a hardware breach impacting their technology.

The Department of Homeland Security said in an Oct. 6 statement that it has "no reason to doubt the statements from the companies named in the story."
