Lubian attack: The Bitcoin robbery of $ 14.5 billion that was not detected for years
In a revelation that has sent shock waves through the global cryptocurrency community, the Blockchain Arkham intelligence platform has discovered one of the main and hidden digital asset thefts of history. Nicknamed the “lubian attack”, the incident focuses on the theft of 127,426 bitcoins of an important Chinese Bitcoin mining group in December 2020. At the time of theft, the Bitcoin stolen was worth approximately $ 3.5 billion. Fast progress until 2025, and the value of the assets committed now exceeds the amazing $ 14.5 billion.

What makes this case especially extraordinary is not only the size of the stolen quantity, but also the fact that the violation remained hidden for almost four years. Neither the mining group nor the hacker revealed the attack, which allowed it not to be informed until Arkham’s recent investigation brought to light the crime.
Timeline of a historical robbery
According to Arkham’s detailed timeline, the attack began on December 28, 2020. That day, cybercriminals were successfully infiltrated in the storage infrastructure of the mining group, obtaining control of 90% of their Bitcoins holdings. Only one day later, on December 29, the computer pirates attack again, this time aimed at a wallet that operates in the Bitcoin omni layer. Additional $ 6 million in BTC and USDT were diverted in this second wave.
Then, on December 31, 2020, the mining group began emergency actions to protect what was left. A total of 11,886 digital assets moved to safer wallets as part of their recovery plan. Today, that remaining amount is worth more than $ 1.35 billion.
A quiet answer: secret messages to hacker
In a highly unusual movement, the affected mining group chose not to reveal the violation of the public or regulatory bodies. Instead, they took a quiet and desperate approach, communicating directly with the attacker. The records show that between 2021 and 2024, the group sent a total of 1,516 messages op_return to wallets that support the stolen bitcoin.
These messages in the chain requested the return of the stolen funds, an act that cost approximately 1.4 BTC to execute. The content of the messages has not been published in its entirety, but the intention was clear: a direct attraction to the Hacker consciousness.
This decision to remain silent and communicate covert with the attacker has caused controversy. Critics argue that such behavior undermines confidence in the cryptocurrency ecosystem and highlights an obvious lack of transparency in the management of security incidents.
Attack anatomy: defective key generation
Arkham’s analysis identifies a critical vulnerability in the private key generation protocol used by the mining group. Specifically, the group was based on a weak algorithm that produced easily predictable private keys. This opened the door for a brute force attack, a method in which hackers try thousands or millions of combinations to guess the correct key.
When this weak security architecture exploded, computer pirates obtained full access to wallets and their contents. Arkham’s findings illustrate that even large -scale professional mining operations are not immune to fundamental security carelessness.
“Lubian’s attack is a marked reminder that operational security must be a priority,” said an Arkham spokesman. “Even the largest industry players are vulnerable if they do not implement robust cryptographic practices.”
The consequences: Who contains the stolen bitcoin?
As of July 2024, stolen funds have not moved or liquidated. On the other hand, the Hacker consolidated holdings in a series of new wallets, that Blockchain analysts remain under nearby surveillance.
Arkham reports that the wallets now associated with Lubian’s attacker collectively make the individual or the group the largest owner of Bitcoin worldwide. This unprecedented classification has further promoted interest in the case, since many wonder if the agencies of the law or international agencies will try to recover stolen assets.
Despite the amazing value of theft, there have been no arrests, and no formal investigation has been published before the Arkham report.
A warning story for the cryptographic sector
Lubian’s attack has already begun to remodel conversations about security in digital asset space. Experts say that the incident highlights the urgent need for more rigorous cybersecurity standards throughout the industry, especially between pools and mining exchanges.
“It is not enough to be fast or profitable in this space,” said Maya Linton, cybersecurity researcher in Cryptoshield. “If you are not sure, you are a goal. And you may not even know that it has been beaten until years later.”
Industry leaders now ask for mandatory security audits, real -time threat detection systems and public transparency when infractions occur. There is also increasing pressure on regulators to implement more strict compliance rules to prevent such incidents from occurring in the future.
Why does it matter: a turning point in the history of Bitcoin
While the previous high profile hacks, such as the rape of Mount Gox in 2014 or the Bybit attack, reached the headlines and caused radical changes, Lubian’s attack may be the most significant theft in Bitcoin’s history. Not only exceeds all previous records in terms of monetary value, but also raises serious concerns about the way cyber attacks are handled, or are not handled, by the main players in the cryptographic world.
“This is a attention call,” said Jackson Wu, a blockchain security analyst based in Singapore. “Not only for miners, but for each institution that has digital assets. If one of the world’s largest mining pools can be compromised and remain silent for four years, we have a serious problem of responsibility.”
Looking to the future: What comes next?
The discovery of Lubian’s attack has opened the door to new investigations. There are questions about who was behind the attack, why the mining group remained silent and if the law enforcement agencies will now intervene that the violation has been publicly exposed.
For now, Arkham’s findings are a historical investigation, one that not only illuminates a dark chapter in the history of Bitcoin, but also serves as a powerful reminder of the importance of surveillance, transparency and innovation in the world of fast -movement digital finances.
