The data leak and negotiation sites for the Ragnar Locker ransomware group went offline Thursday after an international law enforcement operation seized its infrastructure.

Law enforcement agencies participating in the crackdown include the FBI, as well as authorities in France, Germany, Italy, Spain and the Netherlands, backed by Europol’s European Cybercrime Center as well as the EU Agency for Criminal Justice Cooperation.

Europol confirmed the takedown to Bleeping Computer – which first reported on Ragnar Locker being disrupted – and said it planned to formally announce the disruption on Friday, after unspecified additional efforts have concluded.
