Shocking! The biggest theft in history? The Chinese Mining Pool LuBian was robbed, with stolen assets exceeding Mt.Gox.

Recently, blockchain analysis firm Arkham Intelligence revealed that the Chinese Mining Pool LuBian suffered a major hack in December 2020, losing over 90% of its BTC. Worse still, by the end of that month, its Omni layer address was hacked again, resulting in the theft of approximately $6 million in BTC and USDT.

It is reported that the total amount stolen reached 127,426 BTC, which was approximately 3.5 billion dollars at the time of the price, while at the current price estimate, the loss has even reached as high as 14.5 billion dollars, making it one of the largest cryptocurrency thefts in history.

Despite the fact that the LuBian Mining Pool once accounted for 6% of the global Bitcoin hash rate, ranking in the top ten, this catastrophic attack seems to be the real reason for its mysterious shutdown in early 2021, rather than the publicly stated regulatory pressures. Notably, this theft lasted for over four years without being detected, and neither LuBian nor the hackers have publicly acknowledged the matter.

Arkham analysis believes that the theft originated from the weak private key generation mechanism of the Mining Pool, making it vulnerable to brute force attacks. After the incident, LuBian attempted to recover the funds by sending over 1500 small transactions with attached requests for a refund, but the hacker has remained unresponsive.

In the end, LuBian only has 11,886 BTC (approximately $1.35 billion), while the remaining stolen BTC is still in the hands of the hacker. The hacker's last operation was the merging of wallets in July 2024, and now they are the 13th largest holder of Bitcoin tracked by Arkham, even surpassing the hackers of the Mt. Gox theft.

Turning attention to the broader field of crypto security, cybersecurity company Certik reported that in July alone, the reported losses from vulnerabilities and scams amounted to approximately $153 million, of which exchange losses were $86.6 million and code vulnerabilities accounted for $55.4 million.

According to the Hacken report, DeFi losses amounted to $3.1 billion in the first half of 2025, marking the "worst quarter since early 2023." The report also pointed out that the surge in social engineering and AI attacks is the main reason for the dramatic increase in losses, with the losses in just the first half already surpassing the total losses for the entire year of 2024.

In summary, from the theft of Mining Pools to frequent attacks on DeFi, the security challenges in the crypto space are relentless. As investors, the alarm bells for security must always ring!
