Blockchain security company Bit Jungle said in a statement that the hacking of Poloniex exchange may be due to a very professional APT attack, which led to the theft of hot wallet private keys or malicious use of the withdrawal interface. Currently, it is monitored that assets such as BTC and XRP have not been further transferred, but the ERC-20 tokens and TRC-20 tokens stolen from the ETH chain and TRON chain are being converted into ETH and TRX main chain coins by hackers through platforms such as Uniswap and Sushiswap, and are very likely to continue to be transferred and hidden through cross-chain bridges and mixed currency protocols.
