Vulcan Ransomware: A Threat Analysis and Removal Guide

What is Vulcan Ransomware?

Vulcan is a ransomware variant designed to encrypt files on a victim’s device, rendering them inaccessible without a decryption key. Discovered through samples uploaded to VirusTotal, this malware poses a significant threat by encrypting files, renaming them with random strings, and appending the “.vulcan” extension. For instance, “1.jpg” becomes “7d9b9cc3ed944b141fc5151f9ff94ae2.vulcan,” while “2.png” changes to “3f919d4b5aec9d7fc4f1e9b41c5c3.vulcan.”

Victims of Vulcan ransomware are presented with a ransom note demanding 100€ in Bitcoin within 24 hours. The note threatens irreversible data loss and system unbootability if the payment is not made. Contact instructions include sending proof of payment to an email address (kawsexpress@yahoo.com) to receive a recovery tool.

How Does Vulcan Ransomware Spread?

Ransomware like Vulcan spreads through:

1. Malicious Email Attachments: Files containing macros or executable scripts.
2. Pirated Software and Cracking Tools: These often conceal ransomware within their installation files.
3. Infected Websites: Torrent platforms, malicious ads, and third-party downloaders.
4. Exploiting Vulnerabilities: Cybercriminals target unpatched software vulnerabilities.
5. Infected USB Drives: Physical distribution of ransomware through hardware devices.

Symptoms of Vulcan Ransomware Infection

• Files renamed with random strings and “.vulcan” extension.
• Inability to open previously accessible files.
• A ransom demand displayed in a pop-up window.
• Potential system instability or unbootable state.

Why Paying the Ransom is Not Recommended

Paying cybercriminals is a risky proposition. There is no guarantee they will provide the decryption tool or that the tool will work. Furthermore, paying encourages criminal activity. Instead, focus on removing the malware and attempting recovery through alternative means.
