The 8 largest security breaches that occurred in cryptocurrency exchanges and networks, leading to billions of dollars in losses, have been compiled chronologically. Ranging from Bybit to Mt. Gox, these attacks highlight the historical security risks of the sector.
Security breaches during the development of the cryptocurrency market have caused major financial losses for investors and platforms. 8 major attacks occurring on platforms such as Bybit, Ronin Network, Poly Network, BNB Chain, Coincheck, FTX, Mt. Gox, and Bitget stand out as the most critical events in the sector's cybersecurity record.
One of the largest losses in the sector occurred on the Bybit platform in February 2025. In the attack attributed to the Lazarus Group by the FBI, 401,000 ETH worth 1.46 billion dollars were stolen. This was followed by the Ronin Network attack with a 625 million dollar loss in March 2022 and the Poly Network attack, where 611 million dollars in assets were targeted in August 2021. In the Poly Network incident, a large portion of the stolen assets was later returned.
In October 2022, 586 million dollars in assets were put at risk on the BNB Chain, while a portion was recovered by being frozen. In January 2018, 523 million NEM tokens worth 530 million dollars were stolen from the Coincheck exchange. In November 2022, assets worth 477 million dollars were transferred from the FTX exchange without authorization.
Historically, between 2011 and 2014, Bitcoin worth 450-500 million dollars disappeared from the Mt. Gox exchange. Finally, in September 2026, it was reported that assets between 350-388 million dollars were affected on the Bitget platform.
