YGVB Virus (.ygvb FILE) Ransomware – Fix & Decrypt Data

The Ygvb virus family is a ransomware-type infection. It encrypts your files using a strong encryption method, making it impossible to decrypt them.

Ygvb uses a unique key for each victim, with one exception:

Offline keys are used when the victim needs to access data without an internet connection. In this case, the offline key is the same for everyone. This means that if someone else gets infected by the virus, then he or she could use the same offline key to decrypt the files.

There are several universal methods for decrypting encrypted.ygvb file, which will be demonstrated here. It is vital to understand the entire instruction manual carefully. Don’t skip any steps. Each step is very important and must complete by you.

Ygvb virus?

DJVU/STOP ransomware is a specific kind that encrypts personal files. It was first discovered and analyzed by Michael Gillespie.

Ygvb virus is an example of a Trojan horse. It is a malicious program designed to do harm without your permission. Once installed, this malware creates a special message file “_readme.txt” and adds it to all folders that contain the modified files.

_readme.txt (STOP/DJVU Ransomware) – The scary alert demanding users to pay the ransom to decrypt the encoded data contains these frustrating warnings
_readme.txt (STOP/DJVU Ransomware) – The scary alert demanding users to pay the ransom to decrypt the encoded data contains these frustrating warnings

Ygvb ransomware appears as a set of processes performing different tasks on a victim’s computer. One of the earliest processes being launched is win-update, a tricky process that shows a fake Windows Update prompt during the attack. The ransomware also runs another process (usually called by four random characters), which scans the system for target files, encrypts them, and then deletes Volume Shadow Copied from the system.

A common mistake made by users who try to use System Restore is that they assume that restoring an earlier version of Windows will get rid of the virus. This is wrong because the malware changes the Windows Hosts file. When you try to access a website that was previously blocked, you’ll see a warning message saying that your connection was interrupted.

Ransomware attacks often try to block access to certain types of websites. This may be done to make sure victims do not get any useful information about an attack or to trick them into paying money. In this case, the attacker has saved two encrypted files on the infected computer. The first file contains the victim’s public encryption key, while the second one contains the victim’s personal identification number.

After all this modification, the malware still continues to work. It drops AZORULT password-stealing Trojan on compromised systems. It has a long list of capabilities, such us: steal passwords, recording keystrokes, taking screenshots, etc.

  • Stealing Steam, Telegram, Skype login/password;
  • Stealing cryptocurrency wallets.
  • Download malware to the computer and run it.
  • Stealing browser cookies, saved passwords, browsing history, and more.
  • Viewing and manipulating files on the victim’s computer.
  • Allowing the hackers to perform other tasks on the victim’s computer remotely.

You can recover the encrypted files with the help of a strong encryption algorithm such as AES-256. But the decryption key must be known in order to recover the original data.

Ygvb works in offline mode. You can’t get access to the AES key because it is stored on a remote machine owned by the criminals.

The message by the ransomware states the following information:

ATTENTION!

Don't worry, you can return all your files!

Do not pay for Ygvb!

_readme.txt file indicates that the computer owners should contact the Ygvb representative within 72 hours starting from when the files were encrypted. On condition of contacting them within 72 hours, users are granted a 50% rebate. However, stay away from contacting them!

I definitely recommend that you do not contact and do not pay these scams. It is one of the best working solutions to recover lost data – just use the available backups or use the Decrypter tool.

Ransomware attacks often use weak encryption keys. As long as the attacker doesn’t know the correct key, he won’t be able to decrypt your files. You should always back up your important files to an external hard drive or online storage service.

How To Remove Ygvb Virus?

In addition to encoding a victim’s files, the Ygvb infection has also started to install the Azorult Spyware on computers to steal account credentials, cryptocurrency wallets, desktop files,

1. Download Removal Tool

You can download GridinSoft Anti-Malware by clicking the button below:

2. Run the setup file

3. Once installed, Anti-Malware will automatically run.

4. Gridinsoft Anti-malware will automatically start scanning for Ygvb viruses. You should check the status frequently during this time.

5. Click on “Clean Now”

When the scan is complete, you will see the list of infections GridinSoft AntiMalware has detected. To remove them, click the “Erase Now” button in the right corner

How To Decrypt .ygvb Files?

You can download the free decryption tool here: Decryptor for STOP Djvu.

1. Download and run the decryption tool.

As soon as you accept the license terms, the main decryptor user interface comes up:

decryption tool

2. Select folders for decryption.

Based on the default settings, decryptor will automatically populate available locations in order to decrypt the currently available drives (connected ones).

Decryptor suggests several options considering the specific type of malware. The currently available options are listed in the Options tab. You may activate or deactivate them here.

3. Click on the “Decrypt” button.

As soon as you add all the desired locations to decrypt into the list, click the Decrypt button in order to initiate decryption. Note that the Main Screen may turn you to a Status View, letting you know of your active process and the decrypted statistics of your data.

The Emsisoft Decryptor might display different messages after a failed attempt to restore your ygvb files:

  • Error: Unable to decrypt file with ID: [your ID]

There is no corresponding decryption key in the Emsisoft decryptor’s database.

  • No key for New Variant online ID: [your ID]
Notice: this ID appears to be an online ID, decryption is impossible

Your original files were encrypted with an online key. So no one else has the same encryption/decryption key pair. Recovery of ygvb files without paying the criminals is impossible. 

  • Result: No key for new variant offline ID: [example ID]
This ID appears to be an offline ID. Decryption may be possible in the future.

An offline key was used, but you can’t restore the files (the offline decryption key isn’t available yet). But, receiving this message is good news for you, because it might be possible to restore your ygvb files in the future. 
It can take a few weeks or months until the decryption key gets found and uploaded to the decryptor.

  • Remote name could not be resolved

It’s an indication of a DNS issue on your PC. Our first recommendation is to reset your HOSTS file back to default.

How to Restore .ygvb Files?

In some cases, Ygvb ransomware is not doom for your files…

Ygvb ransomware encryption method uses byte-by-byte encryption. This means that every single bit of information about the file is encrypted. In addition, the file is saved as a copy. So, if you delete a file, it won’t be gone forever. You can still recover it later.
