Hive Ransomware

Hive Ransomware is a ransomware operation attributed to eCrime (RaaS), active since 2021. Ransomware-as-a-Service disrupted by FBI infiltration. Key capabilities include: Rust-based encryptor, FBI infiltrated, $130M saved, Jan 2023 takedown.

Overview & Operations

Ransomware-as-a-Service disrupted by FBI infiltration. The group has been active since 2021 and operates as part of the broader ransomware-as-a-service ecosystem. Notable technical characteristics include: Rust-based encryptor, FBI infiltrated, $130M saved, Jan 2023 takedown.

Ransomware Threat

Hive Ransomware employs double extortion tactics — encrypting victim data while simultaneously exfiltrating sensitive information for leverage. Organizations that refuse to pay face public data exposure on the group's leak site.

Operator: eCrime (RaaS)
Active since: 2021
Tooling: Rust-based encryptor, FBI infiltrated, $130M saved, Jan 2023 takedown
Extortion model: Double extortion (encryption + data leak)

Tactics, Techniques & Procedures

Hive operators typically gain initial access through phishing, exploiting public-facing applications (VPN, RDP, Exchange), or purchasing access from initial access brokers (IABs). Post-compromise, they deploy Cobalt Strike or similar C2 frameworks for lateral movement before deploying the ransomware payload.

Initial access: Phishing, vulnerability exploitation, RDP brute force, IAB purchases T1566.001 T1190
Execution: PowerShell, WMI, PsExec for payload deployment T1059.001
Persistence: Scheduled tasks, service creation, registry modifications T1053.005
Defense evasion: Security tool tampering, Safe Mode exploitation, BYOVD T1562.001
Lateral movement: RDP, SMB, WMI, admin shares T1021.002
Exfiltration: Custom exfiltration tools, cloud storage, Rclone T1567
Impact: File encryption with custom encryptor T1486

Detection & Defense

Backup strategy: Maintain offline, immutable backups with tested restoration procedures
Network segmentation: Limit lateral movement paths between critical systems
EDR deployment: Behavioral detection for ransomware indicators (mass file modification, shadow copy deletion)
MFA enforcement: Protect RDP, VPN, and admin portals with phishing-resistant MFA
Patch management: Prioritize VPN, Exchange, and remote access vulnerabilities
Threat intelligence: Monitor for Hive IOCs and dark web activity
