Operation Olympia pulls Swiss servers offline and scoops up 12TB of data in latest crime infrastructure crackdown

Law enforcement agencies in Germany and Switzerland have shut down cryptocurrency laundering platform Cryptomixer in Europe's latest pushback against cybercrime infrastructure.

The Europol-led Operation Olympia took place over November 24-28 and saw authorities seize three Swiss servers and the cryptomixer.io domain.

In doing so, officials also swiped 12 terabytes of data and more than €25 million ($29 million) in Bitcoin.
