Arkham: LuBian mining pool lost 127,000 BTC in 2020, but hackers still control it and become the world's 13th largest BTC holder
Odaily Planet Daily reported that according to Arkham, LuBian, a mining pool that was once ranked among the top ten in the world, suffered a major security incident in December 2020. A total of 127,426 BTC were stolen, which was worth about US$3.5 billion at the time. At the current price of the currency, it has reached US$14.5 billion, making it the largest Bitcoin theft in history. In May 2020, LuBian controlled nearly 6% of the Bitcoin network's hash rate, wielding significant industry influence. The attack occurred on December 28, 2020. The attackers, suspected of exploiting a vulnerability in the private key generation algorithm, successfully stole over 90% of the Bitcoin holdings through brute force. The following day, December 29, the hackers transferred a further portion of the BTC, totaling $6 million. Even more unusual, LuBian attempted to plead with the hacker via an on-chain OP_RETURN message, requesting the return of the stolen assets. Officials sent 1,516 transactions with this message, consuming a total of 1.4 BTC, further confirming that the incident was not a fake. Currently, LuBian still holds 11,886 BTC (approximately $1.35 billion), and the hacker's last on-chain activity was an address consolidation in July 2024. As of the disclosure date, the hacker still controls the stolen BTC, but his identity remains unknown. His holdings rank him as the 13th largest BTC holder in the world, even surpassing the Mt. Gox hacker's address.
