BigONE Exchange Hacked: $27 Million Lost

On July 16, Seychelles-based crypto exchange BigONE reported that it had lost over $27 million due to a security breach targeting its hot wallet. The exchange detected unusual activity in the early hours and confirmed it was a third-party attack. According to BigONE's official statement, the attack resulted in the loss of 120 BTC, 350 ETH, 1,800 SOL, and approximately 8.54 million USDT across multiple networks, affecting several cryptocurrencies, including DOGE, SHIB, and CELR. Blockchain security firm SlowMist reported that the supply chain of the exchange had been compromised. They noted that the attack altered account and risk management server operations, allowing the attacker to withdraw funds. Importantly, SlowMist assured that the private keys remained secure. BigONE corroborated this by stating that all private keys are safe and that they have identified the attack vector to prevent any future incursions. The exchange is collaborating with SlowMist to trace the hacker and the stolen funds. In response to the incident, BigONE announced it would absorb all losses incurred and has activated internal security measures to stabilize liquidity. Users can expect the resumption of deposit and trading services shortly.
