What is LockBit Ransomware?

LockBit, active since 2019, is a highly efficient ransomware known for its rapid file encryption. It often targets businesses through phishing emails, exploit kits, or vulnerabilities in remote desktop protocols (RDP). LockBit Ransomware v4.0 continues to use these methods.

Key Features of LockBit Ransomware v4.0

1. Automated Encryption

LockBit v4.0 encrypts files automatically, making it difficult to stop once it infiltrates a network.

Attackers steal data before encryption and threaten to release it if the ransom isn’t paid. The double extortion tactic of LockBit Ransomware v4.0 is particularly concerning.

3. Ransom Note

A file named LockBit_readme.txt provides instructions for paying the ransom.

4. Affiliate Program

5. Targeted Attacks

It focuses on high-value sectors like healthcare, finance, and government. LockBit Ransomware v4.0 specifically targets these high-value sectors.

6. Evasion Techniques

LockBit disables antivirus software, deletes backups, and hides its activities to avoid detection.

Prevention and Mitigation Strategies
