Bloomberg had reported that Chinese spy chips were allegedly used to gather intellectual property and trade secrets from Apple and Amazon. The chips were reportedly assembled in China for San Jose, California-based Super Micro, and could have been subject to a secret US government investigation that started in 2015.

Super Micro has denied these allegations. The company didn't immediately respond to a request for comment.
