Dark Intel Ransomware: Detection, Removal, and Prevention

Introduction to Dark Intel Ransomware

Dark Intel is a ransomware strain recently identified during the analysis of malicious file samples uploaded to various threat intelligence platforms. Like other ransomware types, Dark Intel encrypts files on an infected device, appends the “.encrypted” extension to filenames, and demands a ransom payment in Bitcoin to restore access to the files. This ransomware leaves a ransom note named “Ezz.txt” with instructions for payment.

An example of how Dark Intel renames files:

• 1.jpg becomes 1.jpg.encrypted
• 2.png becomes 2.png.encrypted

The ransom note further states that failure to pay within 48 hours will result in the permanent deletion of the encrypted files, leaving the victim’s data irreversibly lost. Unlike many other ransomware types, Dark Intel does not include any contact information in its ransom note, making negotiation with the attacker impossible.

Overview of Dark Intel Ransom Note

The ransom note provided by Dark Intel contains alarming threats to the victim:

• It claims the attacker can erase all files with a single command.
• Victims are instructed to pay 0.000010 BTC to a specified Bitcoin wallet address.
• The note emphasizes urgency, warning that failure to pay within 48 hours will lead to permanent data destruction.

Bitcoin Address for Payment:

This lack of contact details and the minimal ransom amount suggests the threat actor may aim for quick and widespread infections rather than large individual payouts.

Technical Details

File Encryption

Dark Intel encrypts files using a robust encryption algorithm, rendering them inaccessible without a decryption key held by the attacker. The malware appends the ".encrypted" extension to every encrypted file.

Symptoms of Infection

• Previously accessible files now have the ".encrypted" extension.
• Victims cannot open or use encrypted files.
• The desktop wallpaper is changed to a ransom message.
• A text file named "Ezz.txt" appears, detailing the ransom demands.

Detection Names by Antivirus Vendors

Dark Intel has been identified under various detection names:

• Avast: Win32:RansomX-gen [Ransom]
• DrWeb: Trojan.Encoder.34437
• ESET-NOD32: A Variant Of MSIL/Filecoder.Chaos.A
• Kaspersky: HEUR:Trojan-Ransom.MSIL.Agent.gen
• Microsoft: Ransom:MSIL/FileCoder.AD!MTB

Distribution Methods

Dark Intel ransomware is primarily distributed through:

• Infected email attachments (macros-enabled documents)
• Torrent websites
• Malicious advertisements
• Compromised websites

It may also spread via software vulnerabilities, pirated software, and infected USB drives.

Damage and Consequences

• Data Loss: Files are encrypted and cannot be recovered without a decryption key or a reliable backup.
• Further Malware Infection: Dark Intel can serve as a delivery mechanism for additional malware, such as password-stealing trojans.
• Ransom Payment Risks: Paying the ransom does not guarantee file recovery and may encourage further cybercrime activities.

Removing Dark Intel Ransomware

Step 1: Isolate the Infected Device

• Disconnect the infected device from the internet to prevent further data encryption and stop the ransomware from communicating with its command-and-control server.
• Disable shared drives and network connections to prevent the infection from spreading to other devices.

Step 2: Boot into Safe Mode

1. Restart your computer and press the appropriate key (e.g., F8, F12, or ESC) to access the boot menu.
2. Select Safe Mode with Networking from the options.

Step 3: Use SpyHunter to Remove Ransomware

SpyHunter is an advanced malware removal tool designed to detect and eliminate ransomware threats like Dark Intel.

1. Download SpyHunter: Transfer the installer to the infected computer using a USB drive or external storage device.
2. Install and Run SpyHunter
   • Install SpyHunter on the infected system.
   • Perform a full system scan to identify and remove the Dark Intel ransomware.
3. Remove Detected Threats
   • Review the scan results and select all identified threats, including Dark Intel, for removal.
   • Follow the on-screen instructions to eliminate the malware completely.

Step 4: Restore Files

If you have backups:

• Restore your data from offline backups or a secure cloud service.

If you lack backups:

• Search online for third-party decryption tools that may be available for this ransomware strain.

Preventing Ransomware Infections

Backup Your Data

Regularly back up your files to an external storage device or a secure cloud service. Ensure backups are disconnected from the internet and the local network after each use.

Keep Software Updated

Regularly update your operating system and all installed applications to patch vulnerabilities that cybercriminals may exploit.

Use Reliable Antivirus Software

Install a reputable antivirus program and keep it updated. Enable real-time protection to block malicious files and websites.

Practice Safe Browsing

• Avoid downloading software from unofficial websites, P2P networks, and third-party downloaders.
• Do not open email attachments or click on links from unknown senders.

Disable Macros in Office Files

Cybercriminals often deliver ransomware via macros-enabled Office documents. Disable macros by default to minimize the risk of infection.

Be Cautious with Removable Media

Scan all USB drives and external storage devices with antivirus software before connecting them to your computer.

Conclusion

Dark Intel ransomware is a serious threat that encrypts victims' files and demands a Bitcoin ransom for decryption. Immediate action, such as isolating the infected device and removing the malware using SpyHunter, is crucial to minimizing damage. By implementing preventive measures like regular backups, software updates, and safe browsing practices, users can protect themselves from future ransomware attacks.
