This week, a Bloomberg report claimed Chinese spies infiltrated 30 U.S. companies and inserted microchips into their servers. Now, several of those companies are vehemently denying Bloomberg’s report, including Apple, which released a blog post refuting the claims.

Here’s Apple’s response, in part:

On this we can be very clear: Apple has never found malicious chips, ‘hardware manipulations’ or vulnerabilities purposely planted in any server. Apple never had any contact with the FBI or any other agency about such an incident. We are not aware of any investigation by the FBI, nor are our contacts in law enforcement.

Bloomberg’s report claims microchips not much bigger than a grain of rice were surreptitiously inserted into U.S.-designed servers, capable of siphoning data and letting in new code. Although Apple denies ever finding these chips, Bloomberg’s report claims otherwise, saying companies such as Apple and Amazon quietly removed compromised servers.

“As a matter of practice, before servers are put into production at Apple they are inspected for security vulnerabilities and we update all firmware and software with the latest protections,” Apple said.

Apple’s response goes on to say the company is disappointed by Bloomberg’s reporting, saying the website “might be wrong or misinformed” and possibly confusing their story with a previously-reported 2016 incident, where Apple found an infected drive on a single Super Micro server in one of its labs.

“That one-time event was determined to be accidental and not a targeted attack against Apple,” Apple said.
