Apple and Amazon have strenuously denied Bloomberg’s claims of a sophisticated hardware exploit against servers belonging to them and numerous other entities, including U.S. law enforcement  

Chinese, Apple and chips

Put in very simple terms, the claim is that malicious chips were found inside servers used in data centers belonging to the tech firms.

These chips (it’s claimed) worked to exfiltrate data from those servers, which were themselves sourced from server manufacturer Super Micro. That company’s server products are/were also used by Amazon, the U.S. government, and 30 other organizations. The chips were allegedly put in place by employees bribed by Chinese government agents.

If that’s true, this constitutes a severe security incident. The reporters claim to have a number of witnesses to these events, though all parties strenuously deny the allegations.
