Slow fog cosine: The longer the mnemonic/private key is used online and the more people share it, the easier it is to leak and harder to trace

ChainCatcher news, Slow Mist founder Yu Xian tweeted that a user's four sets of mnemonic phrases were leaked, corresponding to four wallet addresses where funds 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. The longer mnemonic phrases/private keys are exposed to the internet and the more people they are distributed to for shared use, the more likely they are to be leaked, and the more difficult it becomes to investigate the reasons for the leak.
