US authorities are investigating Chinese Bitcoin mining hardware giant Bitmain over potential national security risks tied to alleged remote capabilities, according to Bloomberg.
The leading Bitcoin mining application-specific integrated circuit (ASIC) manufacturer, Bitmain, which is based in China, is reportedly under investigation in the US over national security concerns.
According to a Friday Bloomberg report, an unspecified US official and six other anonymous people familiar with the matter said that Bitmain’s hardware is at the center of a federal investigation known as “Operation Red Sunset.” The investigation, led by the US Department of Homeland Security, reportedly seeks to determine whether the ASICs could be remotely controlled for spying or to sabotage the US power grid.
US authorities previously investigated Bitmain-linked Chinese chip designer Xiamen Sophgo over an alleged business relationship with US-sanctioned company Huawei in October 2024. This was followed by the US Customs and Border Protection Agency halting the delivery of thousands of Bitmain ASICs the following month. Authorities only began releasing the hardware in March this year.
