The National Computer Virus Emergency Response Center has released a report detailing a significant hack on the LuBian mining pool in December 2020, resulting in the theft of approximately 127,000 Bitcoin, now valued at over $15 billion. The report attributes the breach to a vulnerability in the private key generation algorithm, which contained a pseudo-random number flaw exploited by hackers to gain control through brute force. Blockchain analysis indicates that the stolen funds are closely linked to Bitcoin addresses recently seized by the U.S. Department of Justice in October, suggesting they may be the same assets. This connection highlights ongoing efforts to trace and recover stolen cryptocurrency assets.
