Overview

LockBit is arguably one of the most prolific and devastating Ransomware-as-a-Service (RaaS) operations in history. Targeting enterprises, critical infrastructure, and government entities worldwide, the LockBit cartel popularized the 'double extortion' tactic, where data is stolen before being encrypted.

What is LockBit?
Operating since 2019, the group has gone through several iterations, most notably LockBit 2.0 (Red) and LockBit 3.0 (Black). In early 2024, international law enforcement agencies (Operation Cronos) seized significant portions of LockBit's infrastructure, though affiliate groups continue to use leaked builders to launch attacks.

Infection Vectors & Threat Hunting
LockBit affiliates gain initial access via compromised RDP credentials, phishing, or exploiting unpatched vulnerabilities (e.g., in VPN appliances). Once inside, they move laterally using tools like Cobalt Strike and BloodHound. The ransomware itself is incredibly fast, utilizing multithreading and partial file encryption. Threat hunters must focus on the *pre-ransomware* behavior: look for unauthorized usage of PsExec, unexpected RDP sessions, and massive outbound data transfers to cloud storage (using tools like Rclone).

Containment & Response Steps

Ordered checklist for responders. Adapt to your environment and engage professional support for active incidents.

  1. Disconnect the affected network from the internet immediately to halt data exfiltration.
  2. Do NOT power off infected machines immediately, as memory analysis may yield decryption keys or crucial forensic artifacts.

What to Avoid

Common mistakes during response to this family that can destroy evidence, spread the infection, or worsen recovery.

  1. Do not pay the ransom, as it does not guarantee data recovery and funds criminal enterprises.
