The case of 120,000 missing Bitcoins in 2020 revealed: stolen due to "pseudo-random private keys"

Huoxun Finance reported on October 16th that a technical report updated on August 4th by the MilkSad research team revealed the truth behind the sudden transfer of approximately 120,000 Bitcoins (valued at approximately $3.7 billion at the time, and now approximately $15 billion) in December 2020. The research revealed that the wallets associated with these Bitcoins were generated by the Chinese mining pool Lubian.com. Their private keys were not truly random, but rather generated by a flawed pseudo-random number generator (PRNG), making them predictable. The report notes that US law enforcement recently obtained access to the relevant private keys, not through cracking or hacking, but rather by identifying systemic vulnerabilities in the wallet generation mechanism.
