Ransomware network Hive, which has had around 1,500 victims in more than 80 countries, has been hit in a months-long disruption campaign, the U.S. Department of Justice (DOJ) and the European Union Agency for Law Enforcement Cooperation (Europol) revealed. A total of 13 nations participated in the operation, including EU member states, the U.K. and Canada.

Hive has been identified as a major cybersecurity threat as the ransomware has been used by affiliated actors to compromise and encrypt data and computer systems of government facilities, oil multinationals, IT and telecom companies in the EU and U.S., Europol said. Hospitals, schools, financial firms, and critical infrastructure have been targeted, the DOJ noted.
