GruxEr Ransomware – Decrypt Encrypted Files for Free

This article aims to help you remove the Gruxer ransomware infection and restore the AES encrypted files by this ransomware virus.

A ransomware infection going by the name GruxEr has been reported to encrypt the files on the computers it infects and then demand a ransom of $250 in BitCoin from the victims to get the files back. The virus has been detected at the beginning of May 2017 and it has been reported to wreak havoc ever since. It drops a ransom note which asks victims not to shut down their computer or else the files will be permanently lost. In case your computer has been infected by the GruxEr ransomware threat, you should read the following article thoroughly to learn how to remove it from your computer and restore files encrypted by this infection. Be advised to attempt anything suggested in this article and it’s instructions solely at your own risk!

GruxEr Ransomware – How Does It Spread

The distribution of GruxEr ransomware has been reported to be conducted in multiple different methods. The primary methods of those is via spreading a Trojan-type of executable via fake updates, game patches, key generators or other online file sharing services. The executable of GruxEr ransomware has been detected to be the following:

As soon as the malicious executable of GruxEr ransomware has been opened, the virus drops multiple files on the victim’s computer, predominantly located in %Temp% directory. The files are reported to have the following name:

  • GRUXER.EXE
  • TEARS.EXE
  • WORM.EXE

One of the files hints of a possible method of spreading the GruxEr ransomware via a worm infection, which is particularly dangerous. The main reason for this is that worms unlike other malware may spread automatically from a computer to computer via open ports of the network or automatically generated requests.

GruxEr Ransomware – In Depth Analysis

Believed to use the HiddenTear source code for file encryption, called Tears, the virus initially begins to block the screen of the user’s computer using the GRUXER.EXE module. The blocked screen has the following ransom note:

Your documents, photos, databases and other important files have been encrypted with the strongest encryption known to man. And is secured with a unique key, generated for this computer. The private decryption key is stored on a secret Internet server and nobody can decrypt your files until you pay to obtain your key.
You must pay $250 in Bitcoin to the bitcoin address below.If you do not have Bitcoin visit the site Localbitcoins and purchase $250 USD worth of bitcoin. Within 2 minutes of recieveing your payment, an automated bot will send your computer your personal decryption key.
You have 72 hours to submit the payment. If you do not send the money within the provided time, all your files will be permanently crypted and no one will ever be able to recover them.

After this, the GruxEr virus encrypts the files on the compromised computer and it’s final phase is to keep spreading by a .JPG infection worm, via the WORM.EXE module. This infector looks for JPG files and rewrites the beginning of those files using PNG file architecture.

GruxEr Ransomware – Encryption Process

The process of encrypting files is performed via the TEARS.EXE module. When it is activated, it begins to apply the AES encryption algorithm which generates a decryption key afterwards. The files that the virus may target are believed to be the following types:

→ “PNG .PSD .PSPIMAGE .TGA .THM .TIF .TIFF .YUV .AI .EPS .PS .SVG .INDD .PCT .PDF .XLR .XLS .XLSX .ACCDB .DB .DBF .MDB .PDB .SQL .APK .APP .BAT .CGI .COM .EXE .GADGET .JAR .PIF .WSF .DEM .GAM .NES .ROM .SAV CAD Files .DWG .DXF GIS Files .GPX .KML .KMZ .ASP .ASPX .CER .CFM .CSR .CSS .HTM .HTML .JS .JSP .PHP .RSS .XHTML.

After it encrypts the files on the compromised computers, the virus may add the following text in their strings:

“Files has been encrypted with hidden tear
Send me some bitcoins or kebab
And I also hate night clubs desserts, being drunk.”

Fortunately files encrypted by this ransomware virus may be decryptable, since it is part of the hidden tear ransomware viruses. But first, it is very important to remove the files that are malicious from your computer and the registry objects as well as other settings. To do this, we advise you to follow the instructions underneath.

Remove GruxEr Ransomware

Before begging to remove GruxEr from your computer, we strongly suggest that you extract the encrypted files. However, the ransomware appends a lockscreen via the GRUXER.EXE module. And what is worse is that the virus warns you that the files will be permanently lost if your computer is shut down. This is believed to be a scareware message, but we strongly advise not to rely on this information.

The best course of action is to turn off your computer by force, by cutting the power to it, whether it is via the power source or battery (laptop). Then, we advise following the below-mentioned steps:

1. Download a live operating system on your computer which boots from a flash drive. Make sure the live OS is Windows and has what is known as AntiWinLocker which unlocks folders of Windows if you boot from a live OS and bypasses user accounts. One of those live Windows OS’s is called Windows 7 LiveCD [Xemom1]. You can find it on many torrent sites.

2. Install the live OS on a flash drive via software, such as Rufus. If you are having difficulty using rufus, you can follow the instructions on our forum. Use a safe PC, not the one you just turned off.

3. The final step is to follow these instructions in order to boot your computer without risk. This can happen if you remove it’s hard drive and attach it to another safe PC so that you can access the encrypted files and copy them to the Safe PC.

We prefer to give you the “hands-on approach” because it is less complicated and can bypass any Windows login screens, etc. But for this to work, you will need the following tools:

A crossed screwdriver, preferably with changeable tips. For smaller screws.
cross-screwdriver-sensorstechforum
A SATA cable or SATA to USB external drive converter box. Usually, costs around 10$ to 20$.
external-drive-disconnected-sensorstechforum
A USB-to-USB cable, male on both sides. (Usually, it is included in a SATA to USB External drive maker kit)

Now it is time to get down to business. Before beginning, bear in mind that even if you have a desktop PC, the instructions do not differ much, because the same principles are applied. We have decided to perform those instructions for laptops because they are most widely spread amongst other PCs.

Step 1: Remove the battery from your laptop and unscrew the screws from it to remove the hard drive, like the pictures below display:

sensorstechforum-laptop-remove-bolts-sensorstechforum

hard-drive-removal-sensorstechforum-768x432

Step 2: Make sure to extract the module with SATA conversion board and port and insert the SATA drive into it.

external-drive-disconnected2-sensorstechforum

Step 3: Connect the drive to your computer. It should display as a “Removable Disk” or “Local Drive” with a drive letter other than your original drives. (ex. G:, E:, F:)

drive-sensorstechforum-unmounted

Step 4: Copy your files. Now all that is left for you is to access your files, depending on where they are located. If your drive has two partitions, you will see this as two removable drives connected to your computer. In case you keep all your important files in only one partition, and cannot find them on the primary drive, you should go to the following location to access your profile:

DriveLetter:\Users\{Username}\

There you should be able to see all of your profile’s folders:

important-folders-windows-sensorstechforum

After having done this, we advise you to copy the files onto an external drive or better – write them on a disk so that they are safe and unmodifiable by any malware or crashes that may occur on your computer.

IMPORTANT! MAKE SURE THAT THE SAFE PC IS OFFLINE AND HAS ACTIVE ANTIVIRUS PROTECTION, BECAUSE THE VIRUS HAS WORM SPREADING CAPABILITY! COPY ONLY THE IMPORTANT FILES!

Then, you can boot your computer into Safe Mode and safely remove the virus files, by following the instructions down below. Malware researchers strongly advise to remove the Lockscreen first, by locating the string ScreenSaver:

HKCU\Control Panel\Desktop

To open the Windows registry editor, first boot in Safe Mode:

GruxEr-FAQ

What is GruxEr Ransomware?

GruxEr is a ransomware infection - the malicious software that enters your computer silently and blocks either access to the computer itself or encrypt your files. 

Many ransomware viruses use sophisticated encryption algorithms to make your files inaccessible. The goal of ransomware infections is to demand that you pay a ransom payment to get access to your files back.

What Does GruxEr Ransomware Do?

Ransomware in general is a malicious software that is designed to block access to your computer or files until a ransom is paid.

Ransomware viruses can also damage your system, corrupt data and delete files, resulting in the permanent loss of important files.

How Does GruxEr Infect?

Via several ways.GruxEr Ransomware infects computers by being sent via phishing emails, containing virus attachment. This attachment is usually masked as an important document, like an invoice, bank document or even a plane ticket and it looks very convincing to users.

Another way you may become a victim of GruxEr is if you download a fake installer, crack or patch from a low reputation website or if you click on a virus link. Many users report getting a ransomware infection by downloading torrents.

How to Open .GruxEr files?

You can't without a decryptor. At this point, the .GruxEr files are encrypted. You can only open them once they are decrypted using a specific decryption key for the particular algorithm.

What to Do If a Decryptor Does Not Work?

Do not panic, and backup the files. If a decryptor did not decrypt your .GruxEr files successfully, then do not despair, because this virus is still new.

Can I Restore ".GruxEr" Files?

Yes, sometimes files can be restored. We have suggested several file recovery methods that could work if you want to restore .GruxEr files. 

These methods are in no way 100% guaranteed that you will be able to get your files back. But if you have a backup, your chances of success are much greater.

How To Get Rid of GruxEr Virus?

The safest way and the most efficient one for the removal of this ransomware infection is the use a professional anti-malware program.

It will scan for and locate GruxEr ransomware and then remove it without causing any additional harm to your important .GruxEr files.
