$14.5 Billion Bitcoin Heist: How LuBian Lost 127,426 BTC in the Largest Crypto Theft in History

| $14.5 Billion Bitcoin Heist |
In a revelation that has sent shockwaves across the crypto world, blockchain analytics firm Arkham Intelligence has uncovered the largest known Bitcoin theft to date. The Chinese-based mining pool LuBian lost a staggering 127,426 BTC in a 2020 hack — a sum now valued at over $14.5 billion.
Timeline of the Incident
According to Arkham, the breach occurred on December 28, 2020. The attacker managed to siphon off more than 90% of LuBian’s total Bitcoin holdings before the company could react. LuBian only managed to transfer 11,886 BTC to its backup wallets. The incident went largely unreported at the time, with both the victims and the attackers remaining silent—until now.
The Scale and Mystery Behind the Breach
At the time of the hack, LuBian ranked among the top six largest Bitcoin mining pools, branding itself as "the safest high-yield pool in the world." Just months later, in February 2021, the pool abruptly shut down operations. Many speculated the closure was due to government crackdowns or a pivot to a private operation, but Arkham’s recent findings point to the massive theft as the true cause.
How Was the Hack Possible?
Arkham’s investigation revealed that LuBian used a flawed private key generation algorithm—one vulnerable to brute-force attacks. This critical security lapse appears to have been the attack vector that allowed the hacker to drain such a significant amount of funds.
In an unusual attempt to communicate, LuBian embedded over 1,500 messages into the Bitcoin blockchain's OP_RETURN field, spending 1.4 BTC in the process. One message read:
“To the white hat hacker who is saving our assets. Contact us to discuss a return and your reward.”
No response was ever received. The stolen bitcoins remain untouched on the blockchain to this day, leading some analysts to speculate that the hacker has either been apprehended or is avoiding detection by not moving the funds.
Comparison to Other Major Crypto Thefts
To understand the scale of this breach, it’s worth noting that the previous record-holder—the Bybit exchange hack—resulted in a loss of just $1.5 billion. The LuBian attack has set a new benchmark for crypto-related breaches, eclipsing even the most high-profile incidents in the industry’s history.
Key Takeaways for Crypto Security
Arkham Intelligence emphasizes that this event underscores the critical need for robust cybersecurity in the cryptocurrency sector. Their key recommendations include:
- Using secure random number generators when creating private keys.
- Implementing multi-layered wallet protection and cold storage solutions.
- Conducting regular audits and penetration tests to identify vulnerabilities early.

Final Thoughts
The LuBian theft serves as a stark reminder of the evolving risks in the blockchain ecosystem. As the value of cryptocurrencies continues to surge, so does the incentive for malicious actors. For companies and individual investors alike, vigilance, transparency, and advanced security protocols are no longer optional—they are essential.
