VXUG Ransomware: A Comprehensive Guide on Removal and Prevention

Ransomware is a type of malicious software, or malware, designed to extort money from its victims by encrypting their files and rendering their devices useless until a ransom is paid. This form of malware has become increasingly sophisticated over recent years, and one of the more recent threats is VXUG Ransomware. This dangerous malware variant targets individuals and organizations alike, often leaving lasting damage even after removal. In this article, we will examine the specific workings of VXUG Ransomware, its behavior on infected systems, the symptoms that indicate its presence, and a comprehensive guide to its removal and prevention.

What is VXUG Ransomware?

VXUG is a new strain of ransomware known for its severe impact on systems and encrypted files. A variant of the CryLock ransomware family, it encrypts a wide range of file types on an infected device, leaving them inaccessible and demanding payment from the victim to decrypt their data. Belonging to a larger family of ransomware threats, VXUG is particularly harmful as it utilizes strong encryption algorithms to lock down files, making unauthorized decryption nearly impossible.

Installation and Actions Upon Infection
VXUG Ransomware typically infiltrates a system through phishing emails, malicious attachments, or software vulnerabilities. Once executed on a device, it performs a series of actions:

1. File Scanning and Encryption: The ransomware begins by scanning the system for target files, including documents, images, videos, databases, and more. Using a strong encryption algorithm, it encrypts these files, adding a new extension to each one, appending an email address, a number, and a victim's ID to filenames. For instance, a file originally named “report.docx” would appear as “report.docx[staff@vx-underground.org][1].[F27195A8-B7BFB093]” after encryption.
2. File Renaming: In some cases, VXUG may also rename files alongside adding the new extension, making identification difficult and causing further disruption for users.
3. System Alteration: VXUG may modify system settings, disable antivirus tools, and adjust registry settings to ensure persistence and make removal more difficult.
4. Ransom Note: After encryption, VXUG Ransomware typically drops a ransom note in the form of a text file on the desktop or in affected folders. The note contains instructions on how to pay the ransom, often in cryptocurrency, along with threats to delete or permanently lock files if payment is not made within a specified time.

Consequences of Infection
The consequences of VXUG Ransomware can be devastating. The malware effectively renders all important files inaccessible, causing loss of data and potentially halting business operations for companies. In some cases, even if the ransom is paid, decryption may not be guaranteed, further complicating recovery efforts.

Understanding the VXUG Ransom Note

The VXUG ransom note typically contains the following elements:

1. Ransom Demand: The note clearly states the amount of ransom required for file decryption, often in cryptocurrency (e.g., Bitcoin) to maintain anonymity.
2. Payment Instructions: Detailed instructions are provided on how to purchase and transfer cryptocurrency to the attacker’s wallet address.
3. Deadline for Payment: The attackers often impose a deadline to create urgency, threatening to delete the decryption key or increase the ransom amount after a specific timeframe.
4. Contact Information: Attackers sometimes provide an email address or a link to a secure chat where victims can communicate with them to get additional instructions.

ENCRYPTED BY VXUG

What happened?
All your documents, databases, backups, and other critical files were encrypted by vx-underground. 
Our software used the AES cryptographic algorithm (you can find related information in Wikipedia).

It happened because of security problems on your server, and you cannot use any of these files anymore. The only way to recover your data is to buy a decryption key from us.

To do this, please send your unique ID to the contacts below.
E-mail: staff@vx-underground.org
Unique ID: [F27195A8-B7BFB093]
Right after payment, we will send you a specific decoding software that will decrypt all of your files. If you have not received the response within 24 hours, please contact us on twitter @vxunderground.
During a short period, you can buy a decryption key with a 50% discount
4 days 23:48:49
The price depends on how soon you will contact us.All your files will be deleted permanently in: 6 days 23:48:49
Attention! 
! Do not try to recover files yourself. this process can damage your data and recovery will become impossible. 
! Do not waste time trying to find the solution on the Internet. The longer you wait, the higher will become the decryption key price. 
! Do not contact any intermediaries. They will buy the key from us and sell it to you at a higher price. 
What guarantees do you have?
 
Before payment, we can decrypt three files for free. The total file size should be less than 5MB (before archiving), and the files should not contain any important information (databases, backups, large tables, etc.)

Symptoms of VXUG Ransomware Infection

Detecting ransomware early can be critical. Below are some common symptoms indicating a VXUG infection:

• File Extensions Change: Files display a new extension (e.g., ".vxug") and become unreadable.
• System Performance Issues: The computer may slow down significantly as the ransomware runs encryption processes in the background.
• Appearance of Ransom Note: The presence of a ransom note file (usually in .txt format) on the desktop or in multiple folders.
• Disabled Security Software: Your antivirus or other security tools may stop functioning as VXUG attempts to disable them.

Detection Names for VXUG Ransomware

Different antivirus software may identify VXUG Ransomware under various names. Some examples include:

• Win32:VXUG
• Trojan.VXUG.Gen
• Ransom.VXUG.A
• VXUG.Crypt

Similar Threats to VXUG Ransomware

While VXUG is a serious threat, other ransomware types exhibit similar behavior and risks. Some related ransomware families include:

• STOP/DJVU Ransomware: Known for extensive encryption and numerous variants.
• Maze Ransomware: Notorious for data exfiltration and public leaks.
• LockBit Ransomware: Focuses on high-impact encryption and fast spreading.

Comprehensive VXUG Ransomware Removal Guide

Removing VXUG Ransomware is a multi-step process. Here’s a step-by-step guide to help you clean your system:

1. Disconnect from the Internet: Isolate the infected device to prevent the ransomware from spreading or communicating with remote servers.
2. Restart in Safe Mode: Restart your computer and press F8 (or your system-specific key) to enter Safe Mode. This will prevent certain ransomware components from running, making removal easier.
3. Scan with an Anti-Malware Tool (SpyHunter): Download and run SpyHunter to perform a full system scan. SpyHunter is a powerful anti-malware tool that can detect and remove ransomware and other malicious software.
4. Delete Infected Files: SpyHunter will identify the infected files. Use the tool’s built-in functionality to delete them.
5. Restore Files from Backup: If you have a recent backup, restore your files after the ransomware has been removed. Avoid paying the ransom, as payment doesn’t guarantee the attacker will decrypt your files.

Preventing VXUG Ransomware and Other Ransomware Infections

Preventing ransomware infections requires vigilance and proactive security measures. Here are some key steps to consider:

• Use Antivirus and Anti-Malware Software: Always use a reputable tool, like SpyHunter, to protect against ransomware and other malware. Regular scans help catch threats before they cause damage.
• Avoid Suspicious Links and Attachments: Phishing emails are a common ransomware delivery method. Be cautious when clicking links or opening attachments in unsolicited emails.
• Keep Software Updated: Regularly update your operating system, antivirus, and other software to protect against vulnerabilities that ransomware might exploit.
• Backup Important Data: Regularly backup files to an external drive or cloud storage. In case of a ransomware attack, backups ensure you can recover your data without paying the ransom.

Conclusion

VXUG Ransomware is a dangerous malware threat with severe consequences for both individuals and organizations. Taking preventative measures, such as using trusted anti-malware tools like SpyHunter and maintaining secure backups, can protect you from falling victim to this type of attack. By following the removal steps outlined in this guide, you can effectively rid your system of VXUG Ransomware and safeguard your data from future threats.
