Chinese spy chips didn't infiltrate Apple's technology, says CEO Tim Cook, and he wants Bloomberg to retract its story saying they did.

"There is no truth in their story about Apple," Cook told BuzzFeed News on Friday. "They need to do that right thing and retract it."

A report from Bloomberg Businessweek earlier this month said Chinese spy chips were allegedly used to gather intellectual property and trade secrets from the iPhone maker and Amazon Web Services, an Amazon subsidiary that provides cloud computing services. The chips were found in servers assembled by a Chinese company called Super Micro, according to the report, and could have been subject to a secret US government investigation that began in 2015.

Apple immediately denied the report and even told Congress that it was never hacked.
