Cryptocurrency exchange BigONE suffered a cyberattack resulting in the theft of various digital assets valued at $27 million. The platform assured users that private keys and user data were unaffected, and any losses would be reimbursed from available reserves. The attack targeted the platform's hot wallet, and the attack method was identified and contained. BigONE partnered with security firm SlowMist to track the stolen funds. Despite the attack, deposit and trading services were fully restored quickly. Blockchain observatory Lookochain reported that the hackers had already engaged in money laundering, exchanging the stolen assets for 120 Bitcoin, 1272 Ether, 2,625 Solana, and 23.3 million Tron.
