The U.S. government has launched an investigation into potential security vulnerabilities in Bitmain’s mining hardware, raising concerns about the ability of Chinese-owned operations to disrupt critical infrastructure. The Department of Homeland Security (DHS) is reportedly examining whether Bitmain’s equipment could be remotely accessed from China, posing a national security threat. The investigation, dubbed Operation Red Sunset, focuses on determining if specific weaknesses in Bitmain’s hardware could allow for the disruption of the U.S. power grid or other critical systems. Officials have examined seized mining machines and conducted policy discussions, including those initiated under both the Trump and Biden administrations. The probe is particularly relevant as Chinese-owned Bitcoin mines are increasingly being located near sensitive facilities like military bases and data centers.
