Bybit, one of the leading cryptocurrency exchanges, has fallen victim to a massive security breach, resulting in the theft of $1.5 billion in digital assets. This unprecedented cyberattack marks the largest crypto heist in history, raising concerns over the security of digital asset platforms worldwide.
Bybit’s cold wallet, an offline storage system that is intended to enhance security, was compromised by the attack. The stolen funds, which were predominantly in ether, were promptly transmitted across multiple wallets and dispersed through a variety of platforms.
“Please rest assured that all other cold wallets are secure,” Ben Zhou, CEO of Bybit, posted on X. “All withdrawals are NORMAL.”
Bybit ETH multisig cold wallet just made a transfer to our warm wallet about 1 hr ago. It appears that this specific transaction was musked, all the signers saw the musked UI which showed the correct address and the URL was from @safe . However the signing message was to change…

The stolen crypto was tracked as it was transferred to numerous accounts and promptly offloaded by blockchain analysis firms, such as Arkham Intelligence and Elliptic. In Elliptic’s opinion, the breach significantly transcends previous thefts in the segment. This encompasses the $611 million that was plundered from Poly Network in 2021 and the $570 million that was siphoned from Binance in 2022.
The attack was subsequently associated with North Korea’s Lazarus Group, a state-sponsored cyber collective that is infamous for siphoning billions of dollars from the cryptocurrency industry, according to analysts at Elliptic. The organization is recognized for its use of sophisticated laundering techniques to conceal the movement of funds, which are frequently employed to finance North Korea’s regime by exploiting security vulnerabilities.
“We’ve labelled the thief’s addresses in our software, to help to prevent these funds from being cashed-out through any other exchanges,” said Tom Robinson, chief scientist at Elliptic.
The compromise promptly resulted in a surge in withdrawals from Bybit, as users were concerned about the possibility of insolvency. Zhou stated that the outflows had reached a state of equilibrium. He announced that Bybit had obtained a bridge loan from undisclosed partners to cover any unrecoverable losses and maintain operations in order to reassure customers.
The Lazarus Group has a history of targeting crypto platforms dating back to 2017, when the group infiltrated four South Korean exchanges and seized $200 million worth of bitcoin. Industry experts caution that large-scale thefts continue to pose a fundamental risk as law enforcement agencies and crypto monitoring firms endeavor to locate the stolen assets.
“The more difficult we make it to benefit from crimes such as this, the less frequently they will take place,” Elliptic’s Robinson wrote in a post.
This incident underscores the urgent need for enhanced cybersecurity measures and stricter regulatory frameworks to safeguard digital assets against increasingly sophisticated threats.
