Two days ago, Bloomberg released a new issue of Businessweek, with one subject being Chinese spy chips in iCloud servers. Apple strongly refutes this report.
We reported the news last Thursday, and it now seems Apple has given a strong statement against Bloomberg's Businessweek:
The October 8, 2018 issue of Bloomberg Businessweek incorrectly reports that Apple found “malicious chips” in servers on its network in 2015. As Apple has repeatedly explained to Bloomberg reporters and editors over the past 12 months, there is no truth to these claims.
Another part of the statement:
We are deeply disappointed that in their dealings with us, Bloomberg’s reporters have not been open to the possibility that they or their sources might be wrong or misinformed. Our best guess is that they are confusing their story with a previously-reported 2016 incident in which we discovered an infected driver on a single Super Micro server in one of our labs. That one-time event was determined to be accidental and not a targeted attack against Apple.
