☝️ Reig is a DJVU family of ransomware-type infections. This virus encrypts your files (video, photos, documents). The encrypted files can be tracked by specific “.reig” extension. So, you can’t obtain access to them at all.

In this guide I will try to help you remove Reig ransomware for free. Also I will show you decrypt and restore encrypted files.

Reig virus?

Reig can be identify as a STOP/DJVU ransomware.

Reig

🤔 Reig virus is ransomware that originates from the DJVU/STOP family. Its primary purpose is to encrypt files that are important for you. After that ransomware virus asks its victims for a ransom fee ($490 – $980) in BitCoin.

A ransomware is a specific kind of malware that encrypted your documents and then forces you to pay for them. Djvu/STOP ransomware family was first revealed and discovered by virus analyst Michael Gillespie.

Reig virus is similar to other the same DJVU family: Ribd, Cadq, Ygkz. This virus encrypt all common file types and adds its own “.reig” extension into all files. For instance, the file “1.jpg”, will be amended into “1.jpg.reig“, “2.jpg” to “2.jpg.reig” and so on. As soon as the encryption is successfully accomplished, virus generates a special text file “_readme.txt” and adds it into all folders that contain the modified files.

It is better to prevent, than repair and repent!

This text asking payment is for get files back via decryption key:

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

The cryptography algorithm used by DJVU/STOP virus is AES-256. So, if your documents got encrypted with an online decryption key, which is totally distinct. The sad reality is that it is impossible to decrypt the files without the unique key.

If Reig worked in online mode, you can’t gain access to the AES-256 key. It is stored on a remote server owned by the criminals who distribute the Reig infection.

For receiving decryption key the payment should be $980. To obtain the payment details, the victims are encouraged by the message to contact the frauds by email (helpteam@mail.ch).

The message by the ransomware states the following information:

ATTENTION!

Do not pay for Reig!

Please, try to use the available backups, or Decrypter tool

_readme.txt file also indicates that the computer owners must get in touch with the Reig representatives during 72 hours starting from the moment files were encrypted. On the condition of getting in touch within 72 hours, users will be granted a 50% rebate. Thus extortioner will minimize the ransom amount down to $490). However, stay away from paying the ransom!

I definitely advise that you do not contact these crooks and do not pay. The one of the most real working solution to recover the lost data – just using the available backups, or use Decrypter tool.

The peculiarity of all such viruses applies a similar set of actions to generate the unique decryption key to recover the ciphered data.

Thus, unless the ransomware is still under the stage of development or possesses some hard-to-track flaws, manually recovering the ciphered data is a thing you can’t perform. The only solution to prevent the loss of your valuable data is to make backups of your crucial files regularly.

Note that even if you do maintain such backups regularly, they ought to be put into a specific location without loitering, not being connected to your main workstation.

For instance, you may keep the backup on the USB flash drive or some alternative external hard drive storage. Optionally, you may refer to the help of online (cloud) information storage.

Needless to mention, when you maintain your backup data on your common device, it may be similarly ciphered as well as other data.

For this reason, locating the backup on your main PC is surely not a wise idea.

How I was infected?

Ransomware has a various methods to built into your system. But it doesn’t really matter what method was used in your case.

Reig attack following a successful phishing attempt.

Nevertheless, these are the common leaks through which it may be injected into your PC:

hidden installation along with other apps, especially the utilities that work as freeware or shareware;
dubious link in spam emails leading to the virus installer
online free hosting resources;
using illegal peer-to-peer (P2P) resources for downloading pirated software.

There were cases when the Reig virus was disguised as some legitimate tool, for example, in the messages demanding to initiate some unwanted software or browser updates. This is typically the way how some online frauds aim to force you into installing ransomware manually, by actually making you directly participate in this process.

Surely, the bogus update alert will not indicate that you will actually inject the ransomware. This installation will be concealed under some alert mentioning that allegedly you should update Adobe Flash Player or some other dubious program whatsoever.

Of course, the cracked apps represent the damage too. Using P2P is both illegal and may result in the injection of serious malware, including the Reig ransomware.

To sum up, what can you do to avoid the Reig ransomware injection into your device? Even though there is no 100% guarantee to prevent your PC from getting damaged, there are certain tips I want to give you to prevent the Reig penetration. You must be cautious while installing free software today.

Make sure you always read what the installers offer in addition to the main free program. Stay away from opening dubious email attachments. Do not open files from the unknown addressees. Of course, you must always update your current security program.

The malware does not speak openly about itself. It will not be mentioned in the list of your available programs. However, it will be masked under some malicious process running regularly in the background, starting from launching your computer.

How To Remove Reig Virus?

In addition to encode a victim’s files, the Reig infection has also started to install the Azorult Spyware on computer to steal account credentials, cryptocurrency wallets, desktop files, and more.³

How To Decrypt .reig Files?

Restore solution for big “.reig files“

Try removing .reig extension on a few BIG files and opening them. Either the Reig virus read and did not encrypt the file, or it bugged and did not add the filemarker. If your files are very large (2GB+), the latter is most likely. Please, let me know in comments if that will work for you.

The newest extensions released around the end of August 2019 after the criminals made changes. This includes Cosd, Plam, Pola, etc.

As a result of the changes made by the criminals, STOPDecrypter is no longer supported. It has been removed and replaced with the Emsisoft Decryptor for STOP Djvu Ransomware developed by Emsisoft and Michael Gillespie.

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

Download and run decryption tool.

Start downloading the decryption tool.

Make sure to launch the decryption utility as an administrator. You need to agree with the license terms that will come up. For this purpose, click on the “Yes” button:

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

Select folders for decryption.

Based on the default settings, the decryptor will automatically populate the available locations to decrypt the currently available drives (the connected ones), including the network drives. Extra (optional) locations can be selected with the help of the “Add” button.

Decryptors normally suggest several options considering the specific malware family. The current possible options are presented in the Options tab and can be activated or deactivated there. You may locate a detailed list of the currently active Options below.

Click on the “Decrypt” button.

As soon as yo add all the desired locations for decryption into the list, click on the “Decrypt” button in order to initiate the decryption procedure.

Note that the main screen may turn you to a status view, letting you know of the active process and the decryption statistics of your data:

The decryptor will notify you as soon as the decryption procedure is completed. If you need the report for your personal papers, you can save it by choosing the “Save log” button. Note that it is also possible to copy it directly to your clipboard and to paste it into emails or messages here if you need to do so.

The Emsisoft Decryptor might display different messages after a failed attempt to restore your reig 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 reig 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.

ransomware used an offline key, but files could not be restored (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 reig files in the future. 🙂
It can take a few weeks or months until the decryption key gets found and uploaded to the decryptor. Please follow updates regarding the decryptable DJVU versions here.

✓ 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 .reig Files?

In some case Reig ransomware is not doom for your files…

Reig ransomware encryption mechanism feature is next: it encrypts every file byte-by-byte, then saves a file copy, deleting (and not overriding!) the original file. Hence, the physical disk’s file location information is lost, but the original file is not deleted from the physical disk. The cell, or the sector where this file was stored, can still contain this file, but it is not listed by the file system and can be overwritten by data that has been loaded to this disk after the deletion. Hence, it is possible to recover your files using special software.

I recently had my pc infected by the Reig virus. It managed to bypass 2 Antivirus software and 2 malware fighters. Anyway, after realizing it was an online algorithm, it is impossible to retrieve my encrypted files. I also had my backup drive plugged in at the time of the virus, and this was also infected .. or so I thought. Every folder within my backup drive had been infected and was encrypted. However, despite losing some important files, I retrieved almost 80% of my 2TB storage. When I started going through the folders, I noticed the readme.txt ransom note in every folder. I opened some of the folders and found that all files that were not in a subfolder within that folder had been encrypted. However, I found a flaw and glimmer of hope when I went into the subfolders in other folders and found that these files had not been encrypted. Every folder within my c and d drives, including subfolders, had been encrypted, but this was not the case with the backup drive. Having subfolders created within a folder has saved 80% of my data. As I said, I believe this to be only a small loophole on a backup drive. I’ve since found a further 10 % of my data on another hard drive on a different pc. So my advice is if you use a backup drive, create subfolders. I was lucky, I guess. But I was also unlucky that the virus hit as I transferred some files from my back up. Hopefully, this can help some other people in my situation.Jamie Newland

Some pointers for recovery repair of Reig files (true for all STOP/DJVU variants):

I have seen Reig variants fail to encrypt deeper nested folders, so that you can check that. You may find those are not encrypted.

This ransomware saves encrypted data to a new file, deletes the original. So there’s a slight chance part of that deleted file can be recovered using file recovery software. It’s an unlikely application can restore the folder structure, so a free tool like PhotoRec may be as good as any.

This ransomware only partially encrypts (about first 150 KB), so depending on file size and type of data, the not encrypted part may be recoverable.

Recovering your files with PhotoRec

PhotoRec is an open-source program, which is created for file recovery from damaged disks or for file recovery in case if they are deleted. However, as time has gone by, this program can recover the files of 400 different extensions. Hence, it can be used for data recovery after the ransomware attack

At first, you need to download this app. It is 100% free, but the developer states that there is no guarantee that your files will be recovered. PhotoRec is distributed in a pack with other utility of the same developer – TestDisk. The downloaded archive will have the TestDisk name, but don’t worry. PhotoRec files are right inside.

To open PhotoRec, you need to find and open “qphotorec_win.exe” file. No installation is required – this program has all the files it need inside of the archive, hence, you can fit it on your USB drive, and try to help your friend/parents/anyone who was been attacked by DJVU/STOP ransomware.

After the launch, you will see the screen showing you the full list of your disk spaces. However, this information is likely useless because the required menu is placed a bit higher. Click this bar, then choose the disk which was attacked by ransomware.

After choosing the disk, you need to choose the destination folder for the recovered files. This menu is located at the lower part of the PhotoRec window. The best desicion is to export them on USB drive or any other type of removable disk.

Then, you need to specify the file formats. This option is located at the bottom, too. As it was mentioned, PhotoRec can recover files of about 400 different formats.

Finally, you can start files recovery by pressing the “Search” button. You will see the screen where the results of the scan and recovery are shown.

Frequently Asked Questions

🤔 How can I open “.reig” files?

No way. These files are modified by ransomware. The contents of .reig files are not available until they are decrypted.

🤔 Reig files contain important information. How can I decrypt them urgently?

If your data remained in the .reig files very valuable, you most likely made a backup copy.
If not, then you can try to restore them through the system function – Restore Point.
All other methods will require patience.

🤔 You have advised using GridinSoft Anti-Malware to remove Reig. Does this mean that the program will delete my encrypted files?

Of course not. Your encrypted files do not pose a threat to the computer. What happened has already happened.

You need GridinSoft Anti-Malware to remove active system infections. The virus that encrypted your files is most likely still active and periodically runs a test for the ability to encrypt even more files. Also, these viruses install keyloggers and backdoors for further malicious actions (for example, theft of passwords, credit cards) often.

🤔 Reig virus has blocked the infected PC: I can’t get the activation code.

In this situation, you need to prepare the memory stick with a pre-installed Trojan Killer.

🤔 Decryptor did not decrypt all my files, or not all of them were decrypted. What should I do?

Have patience. You are infected with the new version of STOP/DJVU ransomware, and decryption keys have not yet been released. Follow the news on our website.

We will keep you posted on when new Reig keys or new decryption programs appear.

🤔 What can I do right now?

The Reig ransomware encrypts only the first 150KB of files. So MP3 files are rather large. Some media players (Winamp, for example) may be able to play the files, but – the first 3-5 seconds (the encrypted portion) will be missing.

You can try to find a copy of an original file that was encrypted:

Files you downloaded from the Internet that were encrypted, and you can download again to get the original.
Pictures that you shared with family and friends that they can send back to you.
Photos that you uploaded on social media or cloud services like Carbonite, OneDrive, iDrive, Google Drive, etc.)
Attachments in emails you sent or received and saved.
Files on an older computer, flash drive, external drive, camera memory card, or iPhone where you transferred data to the infected computer.

Also, you can contact the following government fraud and scam sites to report this attack:

In the United States: On Guard Online;
In Canada: Canadian Anti-Fraud Centre;
In the United Kingdom: Action Fraud;
In Australia: SCAMwatch;
In New Zealand: Consumer Affairs Scams;
