In total, only according to known data, cryptocurrency funds stolen from the Atomic wallets of the victims were laundered through the above services (in various combinations) with a total value of more than 100 million USD (the real figures may be much higher).
These services are currently not in active contact and refrain from any comments. In addition, some swap services (in particular, SimpleSwap) operate using the liquidity of top exchanges (primarily Binance and Huobi) and are not marked as separate entities in blockchain analyzers, which also makes it difficult to track the movement of stolen funds. In fact, using such swap services, the stolen funds pass through the exchange's "hot wallet" and are fully laundered when they leave the exchange.
It should be noted that anonymous swap services are now more and more often used by fraudsters in practice (not only in cases related to the Atomic wallet hack
), as they allow to launder "dirty" funds without using AML and KYC. And the regulation of this segment of the crypto-market is still at an embryonic level.3.
The current situation with hacking could have been caused by the insufficient level of security in the construction of wallet architecture. From open sources it became known that copies of the private keys of Atomic wallet users' wallets could be transferred to the Atomic wallet company's server. Also, the Atomic Wallet company's server may have hosted wallet recovery phrases that were not sufficiently random, which could also have led to the theft.
