Europol's European Cybercrime Centre coordinated the operation out of its headquarters in The Hague, targeting the so-called Ramnit botnet, a network of computers infected with malware. "We worked together to shut down the command and control servers for the network in various countries across the European Union," Paul Gillen, head of operations at the cybercrime centre, told Reuters.
