Apple has issued strong denials of the report, stating: "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."

According to the report, the problem was discovered in 2015 and confirmed by independent security investigators hired by the cloud providers. A follow-up investigation involving several government agencies was conducted, as well. No consumer data was stolen as part of the alleged campaign, according to the report.
