What is Gash virus/ransomware?

Gash ransomware is a malicious software that belongs to the STOP/DJVU ransomware family, which is known for its widespread distribution and high volume of attacks. Gash ransomware targets Microsoft Windows operating systems and encrypts files on the victim’s computer, demanding a ransom payment in exchange for a decryption key to restore access to the encrypted files.

Gash ransomware is typically distributed through various social engineering tactics, such as disguising the malicious software as freeware, cracks, activators, and key generators. Once the ransomware is executed, it creates a folder in the Windows system directory where it places a copy of itself and changes some Windows settings so that it starts up every time the computer is restarted or turned on.

The malware then collects information about the victim’s computer and tries to establish a connection with its command server (C&C). If the connection is established, the virus sends information about the infected computer to the server and receives the encryption key (the so-called ‘online key’) and additional commands and malware that must be executed on the victim’s computer. If the virus cannot establish a connection with its command server, then it uses a fixed key (the so-called ‘offline key’).

Gash ransomware uses a strong encryption algorithm to encrypt files on the victim’s computer and adds the ‘.Gash’ extension to the end of the file name to mark all encrypted files. The ransomware skips files located in the Windows system directories, files with the extension .ini, .bat, .dll, .lnk, .sys, and files with the name ‘_readme.txt’.

In every directory where there is at least one encrypted file, the virus places a file named ‘_readme.txt’. This file contains a message from the Gash authors, which says that all files on the computer are encrypted and the only way to decrypt them is to purchase a key and a decryptor from the authors of Gash virus.

The ransom demanded by the attackers is $980, but if the victim pays the ransom within 72 hours, then the amount is halved to $490. Gash authors offer victims the opportunity to verify that encrypted files can be decrypted by sending them a small file. However, a single decrypted file cannot guarantee that after paying the ransom, the criminals will provide the victim with a working key and decryptor.

Below is the message left by the Gash ransomware attackers on victims’ computers:

How to remove Gash virus (ransomware)

To successfully decrypt or recover .Gash files, it is essential to eliminate Gash ransomware and its autostart entries. Failing to do so may result in the ransomware re-encrypting the restored files. Stopping the ransomware is a straightforward process and can be accomplished through various methods. One way is to perform a complete system scan using malware removal tools that can detect and remove ransomware infections for free. To make the process more convenient, consider reading this entire guide and saving it on your smartphone or printing it out. This way, you will have easy access to all the necessary steps.

Scanning your computer for malware is crucial since security researchers have discovered that Gash ransomware may install spyware alongside it. Spyware poses a significant security risk as it can steal sensitive information like passwords, login credentials, and contact details from the user.

How to decrypt .Gash files

If your files have the ‘.Gash’ extension, it means they have been encrypted and you can’t open them just by renaming them. To access their contents, you need a decryptor. Luckily, there is a free Gash File Decrypt Tool that can do this for you. Instructions on how to download and use the tool are included below.

To decrypt .Gash files, use Gash File Decrypt Tool

• Download Gash File Decrypt Tool from the following link.
  STOP Djvu decryptor
• Scroll down to ‘New Djvu ransomware’ section.
• Click the download link and save the ‘decrypt_STOPDjvu.exe’ file to your desktop.
• Run decrypt_STOPDjvu.exe, read the license terms and instructions.
• On the ‘Decryptor’ tab, using the ‘Add a folder’ button, add the directory or disk where the encrypted files are located.
• Click the ‘Decrypt’ button.

The Gash File Decrypt Tool is a free tool that can be used to decrypt .Gash files for free, but it can only decrypt files that were encrypted with an offline key. If the files were encrypted with an online key, the free decryptor will not work. However, there are other methods available to recover encrypted files in such cases, which are explained below.

Steps to determine the type of key used for file encryption

To decrypt files encrypted by Gash File Decrypt Tool, it is important to know which key was used during encryption. You can find out the type of key used through two methods. Both methods are effective, but the second method is considered to be more accurate and therefore recommended.

Identifying the Type of Key Using the ‘_readme.txt’ File

• Open the ‘_readme.txt’ file, which is the ransom demand message created by the Dazx ransomware.
• Scroll down to the end of the file.
• Look for a line of text that says ‘Your personal ID’.
• Below this line, you should see a string of characters. This is your personal ID, which is unique to your computer and is used to generate the decryption key.

Identifying the Type of Key Using the ‘_readme.txt’ File

• Open the C drive on your computer.
• Open the ‘SystemID’ directory.
• Look for the ‘PersonalID.txt’ file and open it.
• This file contains a list of ‘Personal IDs’ that match the keys that the ransomware used to encrypt files.

The ‘Personal ID’ is not the key itself, but rather an identification that is associated with the key used for encrypting files. If the ID ends with ‘t1’, then the files were encrypted with an offline key. Conversely, if the ID does not end with ‘t1’, the Gash virus used an online key to encrypt the files. If it is difficult for you to determine which key was used, you can seek assistance by submitting a request in the comment section below.

Gash File Decrypt Tool : “No key for New Variant online ID”

If, when you try to decrypt .Gash files, Gash File Decrypt Tool reports:

No key for New Variant online ID: *
Notice: this ID appears to be an online ID, decryption is impossible

It means that your files are encrypted with an ‘online key’ and their decryption is impossible, since only the vari authors have the key necessary for decryption. In this case, you need to use alternative methods listed below to restore the contents of encrypted files.

Gash File Decrypt Tool : “No key for New Variant offline ID”

If, during decryption of .Gash files, Gash File Decrypt Tool reports:

No key for New Variant offline ID: *t1
Notice: this ID appears be an offline ID, decryption MAY be possible in the future.

It means the following: your files are encrypted with an ‘offline key’, but the key itself has not yet been obtained by security researchers, in this case, you need to be patient and wait a while, in addition, you can also use alternative ways for recovering encrypted data.

If for some reason you were unable to decrypt the encrypted files, then We recommend to follow the news on our Facebook or YouTube channels. So you ‘ll know right away that it ‘s possible to decrypt .Gash files.
