According to CoinMeta, SlowMist Cosine has detected that Chainflip is attempting to block North Korean hackers from laundering money, but the response speed of AML / KYT lags behind the speed of money laundering. The laundering gang splits funds in large quantities through automated methods and transfers them across chains via various bridges. If the funds are intercepted or returned by risk control, they immediately attempt the next laundering route, ultimately converting them into BTC and using Coinjoin to obscure the source of the funds. This money laundering operation continues to evolve.
