Digital Asset Platform BigONE Experiences $27M Robbery by Hackers
BigONE, a popular cryptocurrency exchange based in Seychelles, announced a significant security breach on July 16, 2025. The breach resulted in the theft of approximately $27 million worth of cryptocurrencies from the exchange's hot wallets.
According to the exchange, the stolen cryptocurrencies include 120 BTC, 350 ETH, 1,800 SOL, and 8.54 million USDT. Smaller amounts of DOGE, SHIB, and CELR were also taken. The theft was spread across multiple blockchains, including unspecified ones.
The security breach was attributed to a supply chain attack by blockchain security firm SlowMist. Unlike traditional cyberattacks, a supply chain attack targets the third-party suppliers or vendors that support a system or application. In this case, hackers infiltrated and altered BigONE's operating systems without stealing private keys.
BigONE has confirmed the theft of the listed cryptocurrencies and assured its users that the security of their private keys was not affected by the breach. The exchange has not yet disclosed the specific identity of the attackers.
This incident serves as a reminder for all cryptocurrency exchanges to strengthen their security measures against such sophisticated attacks. It is crucial for the industry to learn from such incidents and work towards creating a more secure environment for users.
As more and more value is being stored and traded on cryptocurrency platforms, the risk of cyberattacks is bound to increase. Exchanges must prioritise security to protect their users' assets and maintain trust in the system.
The BigONE security breach is currently under investigation, and updates will be provided as more information becomes available. In the meantime, users are advised to enable two-factor authentication, use strong passwords, and keep their assets diversified across multiple wallets to minimise the impact of such incidents.
