In February 2025, the crypto world was shaken by an unprecedented attack on Bybit, resulting in the theft of approximately $1.5 billion in Ethereum. This incident became the largest crypto exchange hack in history, surpassing all previous cases of cyberattacks.


 

Timeline of Events

On February 21, 2025, Bybit representatives reported unauthorized access to one of their cold Ethereum wallets. Hackers managed to withdraw around 401,000 ETH, which at the time was worth approximately $1.5 billion. The incident immediately attracted global attention and sparked widespread discussions about the security of cryptocurrency platforms.
 

Hacker Methods and Investigation

The U.S. Federal Bureau of Investigation (FBI) has launched an investigation and is exploring the possible involvement of international hacker groups. Preliminary findings indicate that the attackers used a method known as "TraderTraitor," which enables rapid conversion of stolen assets into Bitcoin and other cryptocurrencies. The funds were then distributed across multiple blockchain addresses to facilitate laundering and eventual conversion into fiat currency.
 

Bybit’s Response and Impact on Users

Bybit CEO Ben Zhou confirmed the breach and assured users that all other wallets and customer funds remained secure. The exchange took immediate steps to fully compensate affected users, securing interim loans from partners and covering approximately 80% of the losses. However, the news of the hack caused panic among users, leading to a massive withdrawal of funds and a sharp drop in Bitcoin’s price.
 

Efforts to Recover the Stolen Funds

Bybit is actively cooperating with international law enforcement agencies and cybersecurity firms to track and recover the stolen funds. The exchange has also announced a $140 million reward for information leading to the capture of the hackers and the return of the stolen assets. Additionally, Bybit has strengthened its security measures to prevent similar incidents in the future.
 

Impact on the Cryptocurrency Market

The Bybit hack significantly affected the cryptocurrency market. Following the announcement of the attack, Bitcoin’s value plummeted, causing a broader decline in the market’s capitalization. Investors rushed to withdraw funds from exchanges, fearing for the safety of their assets. This incident highlighted the urgent need for enhanced security measures on cryptocurrency platforms and reinforced the importance of building user trust in the industry.
 

Possible Motives Behind the Attack

The investigation is considering multiple theories, including the possibility of a targeted attack by a highly skilled hacker group. Experts suggest that the stolen funds could be used for various purposes, including laundering and financing unknown entities.
 

Key Takeaways and Industry Recommendations

The Bybit incident serves as a critical reminder to the entire cryptocurrency industry about the necessity of continuously improving security measures. Exchanges and other platforms must prioritize system protection, conduct regular security audits, and train staff to prevent future breaches. Users, in turn, should remain vigilant and implement additional security measures, such as two-factor authentication, to safeguard their funds.
