Earlier this week, Bloomberg revealed that Chinese spy chips have been hidden secretly on its server Apple and Amazon, while the two companies strongly denied the existence of such an incident. These servers were manufactured by Supermicro.
One more recent one reference says some of these servers are also infected by malware. Both Apple and Facebook have confirmed this fact. However, this attack has nothing to do with the alleged spy chips.
Facebook says it found the infected server 2015 and that malware was present in a "limited number of hardware" that was only used "for trial purposes limited to our laboratories".
Facebook claims that the malware attack did not affect users. However, the situation does not look very good, for a company that is facing strong criticism after data breach which hit 50 millions of people.
Apple, on the other hand, denies having been hit by spy microchip, but has recognized the discovery of malware on a single 2016 server. In the official response given by the company, he mentioned malware as the reason why Supermicro is no longer its supplier.
According to Bloomberg, a Supermicro online portal that facilitated software updates, it was violated by Chinese 2015 attackers. After that, the firmware was modified for network cards that contained the malicious code.
Even though both companies claimed the attack was very small, the fact that Chinese hackers managed to compromise US security is quite important.
