The AudiA6 crypto laundering takedown.

On June 10, an operation led by Europol shut down AudiA6, a service that washed about 336 million euros in crypto for ransomware crews between 2022 and 2025. Two administrators were arrested and more than 30 servers seized.

A laundering service takes coins tied to a crime, moves them through many wallets, pools them with unrelated funds, and returns them "clean" within an hour for a 3 to 10 percent cut. The point is to hide the link between the stolen coins and the wallet that finally cashes out. Picture running stolen cash through dozens of tills to blur where it came from.

A public ledger records every hop and keeps it forever. Analytics firms can still cluster the addresses and follow the money, which is how a pipeline tied to more than 15 ransomware cases was mapped and seized.

Mixing raises the cost of tracing, it does not erase the trail.
