Blockchain’s analysis firm, Arkham Intelligence, said the North Korean Lázaro group was behind the Hack of $ 1.46 billion bybit, which identified the detective of the Zachxbt chain.
In a previous publication on the social media platform X, Arkham offered a reward of 50,000 Arkm tokens for anyone who could identify the attackers for Friday’s trick. Later, the platform said that Zachxbt presented a “definitive evidence” that the attackers were the group of North Korean computer pirates.
“Its presentation included a detailed analysis of the test transactions and connected wallets used before the exploit, as well as multiple forensic graphics and time analysis,” said the publication.

The trick that shook the cryptography market and saw that most prices fell was called “the largest cryptographic robbery of all time, by some margin”, by Tom Robinson, co -founder and scientific chief of elliptical. “The next largest encryption theft would be the stolen of $ 611 million from Poly Network in 2021. In fact, it can even be the largest robbery of all time.”
Blockchain’s data provider, Nansen, told Coindesk that the attackers first withdrew almost $ 1.5 billion in exchange funds to a main wallet and then distributed them to several wallets. “Initially, the stolen funds were transferred to a primary wallet, which later distributed them in more than 40 wallets,” said Nansen. “The attackers made all Steth, CMETH and Methamphetamine to ETH before systematically transferring ETH in increases of $ 27 million to more than 10 additional wallets,” Nansen said.
The attack seemed to have been caused by something called “blind signature”, where an intelligent contract transaction is approved without the integral knowledge of its content. “This attack vector is quickly becoming the favorite form of cyber attack used by advanced threat actors, including North Korea. It is the same type of attack that was used in the violation of the radiant capital and the Wazirx incident “said the Blockchain CEO, gone, gone from Blockoid. Ben Natan.
“The problem is that even with the best key management solutions, today most of the signature process delegates to the software interfaces that interact with DAPPS. This creates a critical vulnerability: it opens the door to the malicious manipulation of the malicious manipulation of the Signature process, which is exactly what happened in this attack, “he said.
The CEO of Bybit, Ben Zhou, previously wrote in X that a hacker “took control of the specific eth eth wallet and transferred the entire ETH in the cold wallet to this unidentified address.” He also confirmed that the exchange “is solvent even if this hack loss does not recover.”
