This file encryption virus, also dubbed as GG Ransomware by malware research experts, aims to encode the files on the computers it infects and add the .GG file extension to them. Then, the virus may drop a so-called ransom note which has clear demands that the victim must pay a hefty ransom fee to get the encrypted files back. In case you have become a victim of this ransomware infection, recommendations are to read the following article thoroughly.
|Short Description||The ransomware encrypts files with encryption algorithm and asks a ransom for decryption.|
|Symptoms||Files are encrypted with a .GG file extension added to them and become inaccessible. A ransom note with instructions for paying the ransom may show as a file.|
|Distribution Method||Spam Emails, Email Attachments, File Sharing Networks.|
|Detection Tool|| See If Your System Has Been Affected by GG Virus |

.GG File Virus – How Does It Infect
For the infection process of this ransomware, there may be several scenarios, via which it may be situated on a computer.
One scenario is if the virus has infected a given computer by using malicious attachments to e-mails. These malicious attachments are usually posing as legitimate documents with malicious macros or executable files, pretending to be legitimate documents. They are usually in an archive, so that they pass through any security check from e-mail providers.

Another scenario of infection also includes a very particular infection method – via fake installers, game patches or cracks. These may either be uploaded on shady torrent websites or other forms of websites which may only seem legitimate. This is why, great caution should be taken when looking for a patch to activate your unlicensed program, and it is recommended to buy it instead.
GG Ransomware – More Information
Once a malicious attachment containing the .GG file virus has been opened, the infection takes place. Initially the infected file may connect to a C2 server. From there, the payload of GG ransomware may be downloaded on the user’s computer. The payload has been reported to contain a GGransomware.exe file, but It may also have other types of support files. These files usually exist In important Windows directories under different names, like the ones on the image below:
After the files have been dropped, the GG ransomware infection may heavily modify the Windows registry editor, adding multiple registry values with custom data in them. This is done to change different settings on computers that have been compromised and allow for encryption to take place uninterruptedly. The usually targeted registry sub-keys are the following:
After this, the virus may also take advantage of the vssadmin and bcedit commands to target the shadow volume copies on the infected computer. They may be deleted by inserting a script that activates the commands in Windows Command Prompt without the user noticing:
GG Ransomware’s Encryption Explained
This particular ransomware virus may use one or more encryption procedure to alter the data of important files on the computers it infects. What is typical for most encryption algorithms, like the one used in .GG ransomware is that bytes of the file are replaced with symbols from the cipher being used. The stronger the cipher, the more difficult for the file to be unlocked and in the same time, more unstable, meaning it could become corrupt if it is not coded properly.
For the encryption process, GG ransomware virus targets the widely used file types, which are documents, text files, databases, photos, music, images and multiple other types of files. Amongst the files which may be encrypted if your computer was infected by these virus are the following:

After the encryption process has completed, the files become no longer able to be opened and carry the .GG file extension after their name:
The .GG file extension may be related to an abbreviation in gaming (good game, suggesting there is no recovery) or may be completely unrelated to the virus and randomly made. Whatever the case may be, security researchers strongly advise against paying any form of ransom to the cyber-criminals behind the GG ransomware infection.
Remove GG Ransomware and Get Back .GG Files
Before any removal is conducted, it is always preferable to backup the files, no matter whether they are encrypted or not. Then, for the removal itself, we recommend using the instructions below, to help you isolate this virus and remove the virus files and registry objects yourself. However, if you lack the experience and want a faster solution, experts always recommend using a specific anti-malware software for such types of threats. It will not only swiftly detect and remove all files associated with GG ransomware on your computer, but will also ensure that you will stay protected in the future as well.
