Summary
The 2025 Bybit hack is known as the largest cryptocurrency heist in history, resulting in a loss of approximately $1.5 billion worth of Ether (ETH) and other ERC-20 tokens. The breach targeted Bybit’s cold wallet, an offline storage system designed to enhance security. Despite the rapid transfer of the stolen assets across multiple wallets and their liquidation through various platforms, Bybit collaborated with industry experts, including Chainalysis, to trace and freeze over $40 million of the stolen funds. The hack, allegedly orchestrated by North Korea’s Lazarus Group, revealed the evolving tactics of state-sponsored cybercriminals and the inherent challenges faced by cryptocurrency exchanges.
The theft coincided with ETHDenver, an annual Ethereum ecosystem conference, and led to increased volatility in the crypto market. This incident, coupled with internal controversies in the Ethereum community, negatively affected market sentiment. In the aftermath of the hack, over half of the stolen ETH, totaling over $605 million, was laundered through a complex process involving multiple intermediary addresses, token swaps, and cross-chain movements. As of February 28, 2025, the laundering of these stolen funds is still ongoing.
The Bybit hack has highlighted the international nature of the crypto market and the vulnerability of investors to severe losses. It has also underscored the importance of crypto insurance in protecting exchanges, businesses, and investors from financial losses due to hacks, fraud, or operational failures. Bybit, the Federal Bureau of Investigation (FBI), and cybercrime investigation firm Elliptic have been actively involved in tracking the stolen funds, with the FBI naming this specific North Korean malicious cyber activity as “TraderTraitor”.
The incident has served as a stark reminder of the complex challenges faced by cryptocurrency exchanges, including robust security measures and diverse regulatory landscapes. As the digital asset industry continues to evolve, the Bybit experience underscores the necessity for continuous innovation, stringent security protocols, and proactive regulatory compliance.
Background Information
Bybit, a leading cryptocurrency exchange established in 2018 by CEO Ben Zhou, has been making headlines for its unprecedented security breach. The organization is based in Dubai, United Arab Emirates, and offers a wide range of services such as cryptocurrency trading, passive income products, and an NFT marketplace, among others. On February 21, 2025, Bybit experienced a significant security breach, leading to a loss of nearly $1.5 billion worth of ether (ETH) – the largest digital heist in the history of cryptocurrency. The stolen assets were primarily ether, but also included other ERC-20 tokens. The stolen funds were rapidly transferred across multiple wallets and liquidated through various platforms. This incident led to heightened volatility in the crypto market and posed broader risks to investors.
In response, Bybit has been actively collaborating with industry experts, including Chainalysis, to trace the stolen assets. The firm managed to freeze more than $40 million in stolen funds from Bybit and is working with public and private sector organizations to seize as much of the stolen assets as possible.
Detailed Account of the Bybit Hack
The Bybit hack is believed to have been orchestrated by North Korea’s Lazarus Group. This cybercriminal entity is known for exploiting security vulnerabilities and using intricate laundering methods to hide the stolen funds, usually in support of North Korea’s regime. The initial intrusion into Bybit’s systems was carried out through social engineering, with the hackers gaining access to Bybit’s user interface by executing phishing attacks against the cold wallet signers.
Upon discovery of the attack, crypto tracking firms quickly tagged the compromised addresses as “Hacked” or “Stolen Funds” and began to monitor the movement of the stolen assets. Nonetheless, the immediate aftermath of the hack saw a rush of withdrawals from Bybit as users feared potential insolvency.
Laundering of Stolen ETH
The stolen funds were rapidly distributed across 50 different wallets, each holding roughly 10,000 ETH. However, according to a SWIFT study, cybercriminals often believe that physical methods of money laundering, such as the use of money mules, offer better obfuscation than modern methods like cryptocurrency. Despite these traditional views, over $605 million worth of Ether (ETH), or more than 54% of the total stolen funds, were laundered as of February 28, 2025.
Investigation into the Bybit Hack
Minutes after the theft, a team of researchers from Elliptic, a cybercrime investigation firm, collaborated with Bybit and other investigators to track the stolen funds and prevent any potential benefits for the North Korean regime. Further investigation revealed that the hackers preferred physical methods of money laundering to modern methods like cryptocurrencies.
The Federal Bureau of Investigation (FBI) also intervened in the case, naming this specific North Korean malicious cyber activity as “TraderTraitor.” The FBI issued a PSA to indicate North Korea’s responsibility for the theft of $1.5 billion in virtual assets from Bybit, which occurred on or about February 21, 2025.
Impact and Repercussions of the Bybit Hack
Market Response
The cryptocurrency market reacted strongly to the news of the Bybit hack. Joseph Edwards, head of research at Enigma Securities, suggested that the market’s initial resilience might be followed by a more pronounced reaction further down the line. He cited a contraction in risk that triggered a cascading sell-off within the crypto markets.
Regulatory Implications
The hack coincided with a series of policy changes in Washington that were anticipated to encourage millions of new investors to venture into the cryptocurrency industry.
The Role of Crypto Insurance
In the wake of the Bybit hack, the role of crypto insurance in protecting exchanges, businesses, and investors from financial losses due to hacks, fraud, or operational failures has gained renewed attention.
Efforts to Track and Recover the Stolen ETH
In the immediate aftermath of the Bybit hack, swift actions were taken to mitigate the fallout and recover the stolen funds. The CEO of Bybit, Ben Zhou, clarified that the company had secured a bridge loan covering 80% of the lost ETH. To prevent the North Korean regime, accused of being behind the attack, from benefiting from the stolen funds, the Elliptic team collaborated with Bybit, their customers, and fellow investigators to trace the stolen funds. The crypto arm of Chicago-based Jump Trading also took part in the recovery efforts. Despite the unprecedented scale of the hack, the financial loss for the exchange was minimized by Bybit’s capacity to cover the loss from its company treasury.
