BackLock Ransomware (.backlock)

BackLock is a newly discovered ransomware strain that encrypts files on infected systems and demands payment for decryption. It appends a unique victim ID followed by the “.backlock” extension to encrypted files and drops a ransom note named “README.TXT” in affected directories.

---

Threat Overview

BackLock operates by encrypting a wide range of file types, rendering them inaccessible without a decryption key. The ransomware’s ransom note instructs victims on how to contact the attackers and warns against using third-party decryption tools, claiming that such actions may lead to permanent data loss.

In-Depth Analysis

How Did I Get Infected?

BackLock ransomware is typically distributed through deceptive means, including:

• Phishing Emails: Emails that appear legitimate but contain malicious attachments or links.
• Drive-by Downloads: Unintentional downloads from compromised or malicious websites.
• Bundled Software: Installation of pirated software or fake updates that include hidden malware.

Simply opening an infected file or clicking on a malicious link can initiate the ransomware’s execution.

What Does It Do?

Upon execution, BackLock:

1. Encrypts Files: Targets various file types, appending a unique victim ID and “.backlock” extension.
2. Drops Ransom Note: Creates “README.TXT” files containing instructions for payment and warnings against third-party tools.
3. Demands Ransom: Instructs victims to pay for a decryption key, often in cryptocurrency.

The ransomware may also attempt to delete shadow copies and backups to prevent data recovery.

Should You Be Worried?

Yes. BackLock poses a significant threat due to its encryption capabilities and the potential for permanent data loss. Victims without reliable backups may find it impossible to recover their files without paying the ransom, which is not recommended.
