A secret investigation conducted by the US Department of Homeland Security (DHS) has placed Bitmain, the world's largest Bitcoin mining maker, at the center of national security debates. Dubbed "Operation Red Sunset," the investigation was launched to investigate whether mining machines manufactured by the China-based company could be used for espionage activities or remotely manipulated to sabotage the US power grid. According to Bloomberg, the investigation was launched months ago and progressed with the coordination of various federal agencies.
Bitmain is one of the most influential players in the crypto mining industry; many large-scale farms operating in the US also have the company's devices. Security concerns were sparked last year by an investigation by the New York Times. The newspaper revealed that some Bitcoin mining facilities linked to Chinese investors were operating next to a Microsoft data center supporting the Pentagon and near a nuclear missile base in Wyoming. A significant portion of these facilities were reportedly powered by Bitmain machines.
China concerns are mounting
A report released in July by the US Senate Intelligence Committee also alleged that Bitmain devices could be manipulated from China and contained "disturbing security vulnerabilities." These allegations further fueled a growing political debate in Washington.
According to Bloomberg, teams under "Operation Red Sunset" examined the chips and firmware of Bitmain devices intercepted at US ports. The investigation also ran parallel to interim meetings of the White House National Security Council. Some of the investigations also covered violations of customs duties and import regulations. However, officials have declined to comment on the findings so far.
Bitmain has vehemently denied all allegations. In a statement to Bloomberg, the company stated that it fully complies with US law and called the claim that the devices can be remotely controlled "absolutely false." The company also stated that the occasional stoppage of products at ports is a standard Federal Communications Commission inspection and that there is nothing unusual about it. Bitmain also denied allegations in the Senate report alleging ties to the Chinese government.
As the investigation resurfaces in Washington, the Trump family's growing influence in the crypto mining industry has further fueled the debate. According to SEC filings, the American Bitcoin initiative, run by Donald Trump's sons in partnership with Hut 8, purchased 16,000 mining devices from Bitmain in August for $314 million. A company spokesperson stated that all devices underwent rigorous security testing and found no vulnerabilities that could allow remote access.
Trump has also denied allegations that the federal investigations are politically motivated. However, there are already rumors that increased scrutiny of Chinese-based technology companies in the US will continue, further impacting the Bitcoin mining industry.
Meanwhile, the future of the "Operation Red Sunset" investigation remains uncertain. The DHS maintains its policy of not commenting on open files, and Bitmain continues to maintain that the allegations are baseless.
