ChainCatcher news, according to market news, a technical report updated by the research team on August 4 reveals the truth behind the incident in December 2020, where approximately 120,000 bitcoins (valued at about $3.7 billion at the time, now about $15 billion) were suddenly transferred.The research found that the wallets associated with this batch of bitcoins were generated by the Chinese mining pool Lubian.com, and their private keys were not truly random but generated by a flawed pseudo-random number generator (PRNG), making the private keys computable. The report indicates that U.S. law enforcement recently obtained the relevant private keys, not through hacking or breaching systems, but by confirming that there were systemic vulnerabilities in the wallet generation mechanism.
