The US Department of Justice has spent months infiltrating and disrupting the Hive ransomware group, the agency announced on Thursday. The DOJ says Hive has targeted over 1,500 victims in more than 80 countries, extorting hundreds of millions of dollars in ransom payments.

Working with German and Netherlands law enforcement, the FBI seized Hive’s servers and websites, allegedly slowing the group’s ability to attack and extort new victims. It first infiltrated Hive’s network in July 2022, providing over 300 decryption keys to Hive’s current victims and more than 1,000 keys to previous victims — preventing over $130 million in ransom payments. The agency hasn’t announced any arrests. However, it’s still investigating the group, according toNBC News.
