The hacker who attacked the KuCoin exchange transferred 425 bitcoins to the mixer for laundering

The hacker who attacked the KuCoin cryptocurrency exchange in September is actively moving and trying to launder bitcoins. This is the conclusion reached by Elliptic analysts.

Elliptic lead researcher Tom Robinson told the Block that they noticed the movement of stolen funds earlier this week. "The thief has now started moving the stolen bitcoins. The process continues, but out of 1,008 stolen bitcoins, 425 BTC was sent to The chipmixer service mixer. It started on Monday morning, " he said.

ChipMixer provides tools for obfuscating bitcoin transactions in order to hide the source of the cryptocurrency's origin. It allows users to make deposits in bitcoin and receive so-called "chips" that can be split and mixed before withdrawal.

As noted by the analyst Ergo, ChipMixer is unlikely to help an attacker hide traces of asset movement, given the amount that it has, and the amount of assets of other users in the service. In other words, the hacker risks continuing to mix bitcoins with their own, so outgoing transfers from the service will be easy to link with incoming ones. Ergo assumes that at least one of the mixing stages was not represented by a single third-party user.

KuCoin was attacked on September 26, losing over $200 million. Subsequently, some of these funds were returned to the exchange or blocked by projects.
