Overview
- Operation Olympia ran November 24–28 in Zurich, led by Swiss and German police with support from Europol and Eurojust, and resulted in the seizure of three servers and the cryptomixer.io domain now displaying a law-enforcement banner.
- Europol describes Cryptomixer as a hybrid service on the clear web and dark web that pooled and redistributed deposits to block on‑chain traceability for ransomware groups, darknet markets and fraud networks.
- Since launching in 2016, the mixer processed roughly €1.3 billion in Bitcoin, marking it as a major laundering hub targeted for disruption.
- Europol’s Joint Cybercrime Action Taskforce provided on‑site forensic support, and authorities say the seized materials will feed follow‑on investigations by agencies including Germany’s BKA and Frankfurt prosecutors and Zurich authorities.
- Cybercrime experts expect only short‑term disruption as criminal laundering shifts to other mixers, cross‑chain bridges or high‑risk exchanges.
