The FBI shared indicators of compromise (IOCs) associated with the Hive ransomware, which they believe “likely operates as an affiliate-based ransomware.” While Hive uses multiple methods to comprise victims’ networks, the FBI highlighted “phishing emails with malicious attachments.” Once a victim’s network is compromised Hive provides “two to six days” for payment of the ransom by the victim. If the ransom is not paid, Hive leaks their victim’s data to their Tor website, HiveLeaks.

Because Hive uses legitimate applications to further their compromise of a victim’s network, “the FBI recommends removing any application not deemed necessary for day-to-day operations.”
