Five days after Bloomberg stunned the world with still-unconfirmed allegations that Chinese spies embedded data-sniffing chips in hardware used by Apple, Amazon, and dozens of other companies, the news organization is doubling down. Bloomberg is now reporting that a different factory-seeded manipulation from the previously described one was discovered in August inside the network of a major US telecommunications company. Bloomberg declined to name the company, citing a non-disclosure agreement between the company and the security firm it had hired to scan several of its large data centers.

Tuesday’s report cites documents, analysis, and other evidence provided by Yossi Appleboum, who is co-CEO of a hardware security firm called Sepio Systems. Bloomberg said that, while Sepio was scanning servers belonging to the unnamed telecom, the firm detected unusual communications from a server designed by Supermicro. Supermicro, according to last week’s Bloomberg report, is the hardware manufacturer whose motherboards were modified in the factory to include a tiny microchip that caused attached servers to come under the control of a previously unreported division of China’s People’s Liberation Army. Supermicro told Bloomberg it had no knowledge of the implant, marking the second time the hardware maker has denied knowing anything about the reported manipulations.
