A major U.S. telecommunications company discovered manipulated hardware from Super Micro Computer Inc. in its network and removed it in August, fresh evidence of tampering in China of critical technology components bound for the U.S., according to a security expert working for the telecom company. The security expert, Yossi Appleboum, provided ... evidence of the discovery following the publication of an investigative report in Bloomberg Businessweek that detailed how China's intelligence services had ordered subcontractors to plant malicious chips in Supermicro server motherboards over a two-year period ending in 2015. [Appleboum's company] was hired to scan several large data centers belonging to the telecommunications company. Unusual communications from a Supermicro server and a subsequent physical inspection revealed an implant built into the server's Ethernet connector. The executive said he has seen similar manipulations of different vendors' computer hardware made by contractors in China, not just products from Supermicro. "Supermicro is a victim - so is everyone else," he said. There are countless points in the supply chain in China where manipulations can be introduced, and deducing them can in many cases be impossible. The manipulation of the Ethernet connector appeared to be similar to a method also used by the U.S. National Security Agency, details of which were leaked in 2013.
