Slow Mist Cosine: The longer the mnemonic/private key is used online and shared by more people, the easier it is to leak and difficult to investigate

BlockBeats News: On May 31st, Cosine, the founder of SlowMist, stated that four sets of mnemonic words were leaked by a certain user, and the funds in four corresponding wallet addresses were stolen. From the perspective of on chain operations, the hacker's address received the funds, exchanged them all for ETH, and then laundered them through FixeFloat. A reminder to everyone, the longer the mnemonic/private key is used online and distributed to more people for shared use, the more likely it is to be leaked, and the more difficult it is to investigate the cause of the leak.
