How to Remove LockBit Black (LockBit 3.0) Ransomware Virus and Restore .LOCKBIT Files?

Introduction: Understanding LockBit Black

LockBit Black, also known as LockBit 3.0, represents the evolution of the infamous LockBit ransomware family. First emerging in mid-2022, this version integrated new evasion techniques, a bug bounty program for affiliates, and an advanced encryption scheme. LockBit has since become one of the most widespread ransomware-as-a-service (RaaS) platforms, impacting critical infrastructure, healthcare providers, government agencies, and private enterprises.

Unlike early ransomware groups, LockBit Black combines stealth, speed, and business-like organization. Its operators not only encrypt files but also exfiltrate sensitive data to pressure victims into payment—a hallmark of the double extortion model.

When LockBit strikes, immediate actions can determine the success of recovery.

  1. Disconnect Affected Devices
    Isolate compromised machines from the network to prevent lateral movement.
  2. Preserve All Evidence
    Keep ransom notes, encrypted files, logs, and network traffic. Do not attempt DIY cleaning.
  3. Avoid Reboots
    Restarting may trigger additional encryption payloads.
  4. Seek Professional Help
    Avoid unverified tools or shady forums. Contact ransomware experts immediately.

Options for Recovering LockBit-Encrypted Data

Free Recovery Approaches

1. Avast’s Legacy Decryptor

For early LockBit versions, Avast released a decryptor exploiting weak key generation. However, it does not work for LockBit Black, which uses upgraded ChaCha20 + RSA encryption.

2. Backup Restoration

If secure offline or immutable backups exist, recovery can be performed by wiping affected systems and restoring clean images. Backup integrity must be validated before use.

3. VM Snapshots

In VMware ESXi or Proxmox environments, reverting to pre-infection snapshots can restore systems quickly—if snapshots were not deleted by attackers.

4. Open-Source Brute Force Attempts

Some researchers have attempted brute-force decryption of LockBit keys using GPU clusters. However, the computational demand makes this infeasible for most victims.


Paid Recovery Approaches

1. Paying the Ransom

Victims sometimes pay LockBit operators through TOR portals. While attackers typically provide decryptors after payment, risks include corrupted files, incomplete recovery, and embedded malware. Legal and ethical concerns also apply.

2. Third-Party Negotiation

Professional negotiators sometimes engage with attackers to reduce ransom costs and validate decryptors. While effective, this is expensive and time-consuming.

3. Our LockBit Black Decryptor (Recommended)

Our decryptor bypasses the need for negotiations or ransom payments by leveraging cryptographic analysis and AI-based blockchain verification. Available for Windows, Linux, and ESXi, it ensures accurate decryption with detailed audit logs.

Intrusion Methods: How LockBit Black Gains Access

VPN and RDP Exploitation

A favorite attack vector involves scanning for exposed Remote Desktop Protocol (RDP) and VPN appliances. Weak credentials, credential stuffing attacks, and unpatched endpoints provide easy entry. Organizations with inadequate monitoring of remote access are particularly vulnerable.

Exploited Vulnerabilities

LockBit Black affiliates aggressively target unpatched devices. Notable exploited flaws include:

  • Cisco ASA vulnerabilities (CVE series) that provide network entry.
  • Fortinet SSL VPN flaws that expose authentication bypass opportunities.

Phishing Campaigns

Sophisticated phishing campaigns distribute weaponized attachments or lure employees into entering credentials on fake login portals. These stolen credentials are then used for lateral movement and privilege escalation.

  • Remote Tools: AnyDesk and Ngrok provide ongoing remote control, bypassing firewalls.

Lateral Movement and Privilege Escalation

Once inside, LockBit affiliates move laterally to maximize reach. Tactics include:

  • Deploying PsExec for executing payloads across networked machines.
  • Leveraging stolen domain admin credentials harvested with Mimikatz.
  • Querying Active Directory using AdFind to identify high-value accounts and servers.

Encryption Workflow

LockBit Black uses a hybrid encryption model:

  • ChaCha20 for rapid file encryption.
  • RSA-2048 to secure encryption keys.

The ransomware also executes:

vssadmin delete shadows /all /quiet

This removes shadow copies and backup points, preventing easy recovery.

Files are renamed with the .lockbit extension, and ransom notes are left in each directory, directing victims to negotiation portals on the darknet.


Exfiltration and Double Extortion

Data theft is a cornerstone of LockBit Black’s strategy. Stolen data is uploaded to attacker-controlled servers and cloud services. If ransom demands are not met, the data is leaked on LockBit’s darknet site. This tactic ensures even organizations with backups face severe pressure to pay.


Affiliates and the Ransomware-as-a-Service Model

LockBit Black operates under a RaaS model, where affiliates rent the ransomware and share ransom profits with core developers. This structure fuels rapid spread, as affiliates bring diverse expertise:

  • Some specialize in initial access (via phishing or exploits).
  • Others focus on network penetration and privilege escalation.
  • Core developers maintain the malware, payment infrastructure, and leak sites.

Unique to LockBit Black was the introduction of a bug bounty program in 2022, offering payments to anyone discovering flaws in the ransomware code—a sign of its corporate-like evolution.
