At approximately 1:21 pm UTC, a known CoinEx hot wallet transferred around 4,947 Ether (ETH), worth $7.9 million at the time, to an Ethereum account. The receiving account had no prior history before this transaction.
Immediately after this transaction, the CoinEx hot wallet began transferring large amounts of tokens to the same address. Approximately 408,741 Dai (DAI) stablecoin, 2.7 million Graph (GRT) tokens, 29,158 Uniswap (UNI) tokens and many other tokens were transferred from the wallet.
Blockchain security firm PeckShield reported the outflow as “suspicious.” CryptoQuant head of research Julio Moreno also claimed that the behavior of the CoinEx wallet was “strange," as Ether reserves “are now basically zero ETH."
At 5:25 pm UTC, CoinEx confirmed on Twitter that the platform had experienced suspicious withdrawals. “[O]ur Risk Control System detected anomalous withdrawals from several hot wallet addresses used to store CoinEx’s exchange assets," the exchange said, adding that a “special investigative team” had been appointed to determine what happened.
The team also claimed that the withdrawn crypto is a small part of the exchange’s total reserves and that users “will receive 100% compensation for any loss due to this breach."Urgent Notice: Security Incident on CoinEx - Immediate Actions Underway
