The hacking incident drew the attention of different crypto companies, including blockchain security platforms.A [report](https://www.binance.com/en/feed/post/1138163) shows that various [ blockchain](https://techreport.com/crypto-news/bridge-between-shibarium-blockchain-and-ethereum-goes-live-for-testing/) security firms have tagged the illegal withdrawals “suspicious”.[Slow Mist](https://twitter.com/congnguyrn/status/1701822495006044626), one of the blockchain security firms, reported that CoinEx lost crypto assets equivalent to $53.96 million.

Again, data from [Etherscan](https://etherscan.io/address/0x8bf8cd7F001D0584F98F53a3d82eD0bA498cC3dE) shows that one of CoinEx’s recognized hot wallets recorded a transfer of 4,947 ETH worth $7.9 million when the transfer occurred.However, the recipient’s wallet had no history of previous transactions, implying it was a new address possibly created for the hacking purpose.
It also recorded that within a short time after the ETH transfer, the CoinEx hot wallet transferred several tokens to that address.The subsequent tokens transferred include 2.7 million Graph (GRT) tokens, 29,158 Uniswap, and 408,741 DAI.Rumors that CoinEx exchange was hacked.At least from an On-chain perspective we’re seeing weird behavior of its ETH reserves.
