UK spymasters and US Homeland Security officials have supported Western tech companies' denials that Chinese agents were able to smuggle hidden surveillance chips into Super Micro servers.

Mainstream media megastructure Bloomberg reported last week that Beijing's military intelligence pressured or bribed a Chinese manufacturing subcontractor of US-based Super Micro to include a small secret spy chip in the server maker's motherboards. The supposedly grain-of-rice-sized chips were inserted to give China a backdoor into the computers, allowing data to be silently altered or stolen from afar by the Chinese government, Bloomberg's numerous sources claimed.
