The UK’s top national cybersecurity agency GCHQ told Reuters on Friday that it didn’t see any reason to question the validity of Apple and Amazon’s denials that their servers were compromised following a meteoric report from Bloomberg on Thursday. The report claimed that Chinese spies were able to place microchips in the companies’ servers, allegedly giving the Chinese government backdoor access to some of the largest cloud platforms in the world.

The GCHQ, which is the UK’s equivalent to the US National Security Agency (NSA), didn’t call for an investigation into the claims, but it requested that anyone with information about the alleged attack reach out. In its response to Reuters, the GCHQ said, “We are aware of the media reports but at this stage have no reason to doubt the detailed assessments made by AWS and Apple,” said the National Cyber Security Centre, a unit of GCHQ.
