BigONE Becomes Latest Target in Ongoing Exchange Hacks
According to an official statement, the incident occurred in the early hours of July 16. After detecting unusual activity, BigONE’s technical team confirmed a third-party attack targeting the exchange’s hot wallet infrastructure. The attacker managed to breach the production environment and alter the logic of servers responsible for account and risk management.
BigONE emphasized that no private keys were compromised. However, manipulation of the internal system allowed the attacker to withdraw a wide range of assets illegally.
On-chain data reveals the attacker stole:
-
121 BTC,
-
350 ETH,
-
9.69 billion SHIB,
-
538,000 DOGE,
along with other assets like USDT and UNI.
This incident follows closely on the heels of the $100 million hack of Iran-based exchange Nobitex last month, highlighting the persistent cyber threats facing the crypto industry.
BigONE Vows Full Compensation, Enhances Security
Immediately after the breach, BigONE suspended deposits and withdrawals and assured users that all private keys remain secure and that the attack vector has been neutralized. The exchange has committed to fully compensating affected users.
BigONE is now working with blockchain security firm SlowMist to track the hacker’s addresses and monitor the movement of stolen funds. In many past high-profile exchange hacks, attackers have gone silent before eventually cashing out, as seen in the recent Coinbase breach where the hacker purchased 4,800 ETH after two months of inactivity.
The exchange announced that deposit and trading services would resume within hours, with withdrawals reactivated once additional security measures are implemented.
Despite the crypto market’s growing maturity, major platforms like Bybit, Coinbase, and now BigONE continue to fall victim to sophisticated cyberattacks — proving that security remains the Achilles’ heel of the digital asset ecosystem.
