SlowMist Yusin: The longer and more people use mnemonic phrases/private keys online, the easier they are to leak and the harder they are to trace

SlowMist founder Yu Jian stated that a user's four sets of mnemonic phrases were leaked, and the funds in the four corresponding wallet addresses were stolen. From the on-chain operation methods, after the hacker's address received the funds, they were all converted to ETH and then laundered through FixedFloat. A reminder to everyone: the longer mnemonic phrases/private keys are used online and the more people they are distributed to for joint use, the more likely they are to be leaked, and the more difficult it becomes to investigate the cause of the leak.
