A major U.S. telecommunications company discovered manipulated hardware from Super Micro Computer in its network and removed it in August, fresh evidence of tampering in China of critical technology components bound for the U.S., Bloomberg reported Tuesday. From the report: The security expert, Yossi Appleboum, provided documents, analysis and other 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 previously worked in the technology unit of the Israeli Army Intelligence Corps and is now co-chief executive officer of Sepio Systems in Gaithersburg, Maryland. His firm specializes in hardware security and was hired to scan several large data centers belonging to the telecommunications company. Bloomberg is not identifying the company due to Appleboum’s nondisclosure agreement with the client. Unusual communications from a Supermicro server and a subsequent physical inspection revealed an implant built into the server’s Ethernet connector, a component that’s used to attach network cables to the computer, Appleboum said.
