Swiss and German authorities, backed by Europol, seized the cryptomixer.io domain, three servers and roughly €25 million in Bitcoin in a coordinated takedown. Investigators say the forensic haul of more than 12 TB of data will support follow‑on probes into ransomware, darknet markets and money‑laundering networks.

Swiss and German law enforcement, supported by Europol, executed a coordinated operation that seized the cryptomixer.io domain, three physical servers, over 12 terabytes of forensic data and about €25 million worth of Bitcoin. Authorities described the disruption as a major blow to one of the largest bitcoin‑mixing services used to obfuscate illicit proceeds from ransomware, darknet markets and other criminal activity. Seized logs, transaction records and server images are being analyzed for traces that can link mixed outputs back to criminal wallets and to intermediaries who facilitated laundering. Officials emphasized that the technical and financial evidence collected will feed follow‑on investigations across jurisdictions, enabling asset tracing, victim restitution efforts and potential prosecutions. Europol assistance reportedly helped coordinate evidence preservation and cross‑border legal processes. Investigators warned that while the takedown disrupts ongoing services, the underlying demand for mixing persists and additional investigative work will be required to dismantle associated criminal networks and identify operators and frequent users.
