North Korean hackers are believed to be behind the largest cryptocurrency theft in history, targeting the Bybit exchange platform and making off with a staggering $1.5 billion. The cyber attack, which occurred on February 21, has sent shockwaves through the cryptocurrency world, raising concerns about security and the increasing sophistication of state-sponsored cybercrime. The Dubai-based Bybit platform, boasting over 40 million users, was the victim of a complex attack that compromised its Ethereum (ETH) assets. Chainysis, a company specializing in analyzing the activities of North Korean-affiliated computer hackers, reported the breach. The sheer scale of the theft dwarfs previous incidents, highlighting the growing threat posed by these actors.

Record-Breaking Theft Exceeds Previous North Korean Cybercrime

The $1.5 billion stolen from Bybit surpasses the total amount pilfered by North Korean agents throughout 2024. According to Chainysis, those agents stole over $1.34 billion in 47 separate attacks. This single incident underscores the escalating boldness and effectiveness of North Korean cybercriminals.

the method used in the Bybit attack suggests a high level of technical expertise and planning. According to TRM Labs, a crime detection platform focused on cryptocurrencies, The attackers committed one of the cold wallets (Cold Wallet) out of the bybit line in what was possibly an attack on the supply chain, an internal threat or a sophisticated commitment of private key. This indicates that the hackers may have exploited vulnerabilities in Bybit’s security infrastructure or gained unauthorized access through insider compromise.

Attribution to North Korea and the Lazarus Group

Both Chainysis and TRM Labs have concluded that North Korean hackers likely perpetrated the cyber attack, citing the tactics employed and the history of similar robberies carried out by these agents. The evidence points towards a coordinated effort by a well-resourced and experienced group.

Chainysis emphasized the strategic nature of the attack, stating, This attack highlights a common strategy used by the RPDC (acronym for the official name of the country, democratic Popular Republic of Korea): orchestrate social engineering attacks and use intricate money laundering methods in an attempt to move stolen funds without being detected. The report further noted, Bybit’s violated funds have also been consolidated in directions that contain funds from other known attacks linked to the RPDC, which provides more evidence that the actors in the nation-state are behind this last incident.

Bybit’s Response and Industry Impact

Following the attack, Bybit founder Ben Zhou attempted to reassure users, stating that only the Ethereum cold wallet was compromised and that other transactions remained secure. Zhou also asserted that the company was solvent and could cover the losses suffered by cyber attack.

Zhou further stated that Bybit had completely closed the ETH gap within three days of the incident. He also announced plans to launch something to help us and the industry to fight against computer pirates and to address the problems of recovery of funds, in the coming days, as posted on his social network X profile.

North Korea’s Cryptocurrency Crime and Weapons Programs

Analysts have long warned that North Korea uses cryptocurrencies to finance its weapons programs. Despite efforts by countries like South Korea and the United States to combat these activities, the volume and frequency of attacks aimed at stealing these assets have increased in recent years.

Arkham Intelligence, another research firm that analyzed the theft, has explicitly linked the cyber attack to the Lazarus Group, a notorious cybercriminal organization backed by the North Korean government. The investigator zachxbt conducted a detailed analysis of the transactions and found connections between the wallets used in the Bybit hacking and an earlier attack by Lazarus on the Phemex Singaporean platform.

The Notorious Lazarus Group

the Lazarus Group is considered the most prominent cybercriminal organization serving the North Korean regime. The group is subject to sanctions by governments, including the United States, for its role in generating revenue for North Korea to circumvent economic sanctions and finance its weapons growth.

The group gained notoriety for infiltrating Sony Pictures’ computer system in November 2014, causing important economic losses and data leaks in response to the movie ‘The interview,’ which North Korea considered offensive to its leader, kim Jong-un.

in recent years, Lazarus has been linked to multimillion-dollar cyber attacks on cryptocurrency platforms such as the South Korean Bithumb and Youbit, as well as the Japanese DMM Bitcoin.

This isn’t just a heist; its a sophisticated act of state-sponsored cyber warfare, showcasing the evolving tactics of North Korea’s Lazarus group and the urgent need for enhanced cybersecurity measures within the cryptocurrency industry.
