US probes Chinese bitcoin-mining machine giant Bitmain over national security concerns: Bloomberg
The US Department of Homeland Security reportedly investigated Bitmain over concerns its bitcoin mining equipment could pose national security risks.Summary
Bitmain, the major Chinese manufacturer of bitcoin mining equipment, has reportedly been the subject of a months-long, undisclosed investigation by the Department of Homeland Security, dubbed "Operation Red Sunset." The probe aimed to assess whether the company's machines could be remotely manipulated for spying or used to compromise the U.S. power grid, following earlier concerns raised after Chinese-owned mining facilities were found near critical U.S. infrastructure. The investigation reportedly included inspecting chips and firmware on machines stopped at U.S. ports and examined potential tariff violations, running parallel to policy discussions within the National Security Council. Bitmain has denied these claims, calling reports of remote control capabilities "unequivocally false" and stating it complies with all U.S. laws. The probe's current status is unclear, and it has gained attention amid the expansion of Donald Trump's sons into the bitcoin mining sector using Bitmain hardware.
