Rigd Virus (. Rigd File) Ransomware

The Rigd virus is a STOP/DJVU family of ransomware-type infections. This virus encrypts your files (video, photos, documents) that can be tracked by a specific “.rigd” extension. It uses a strong encryption method, which makes it impossible to calculate the key in any way.

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

• If Rigd cannot establish a connection to its command and control server (C&C Server) before starting the encryption process, it uses the offline key. This key is the same for all victims, making it possible to decrypt files encrypted during a ransomware attack.

I have gathered a complete collection of all possible solutions, tips, and practices in neutralizing the Rigd virus and decrypting files. In some cases, it is easy to recover your files. And sometimes it is just impossible.

There are several universal methods for recovering encrypted .rigd files, which will be demonstrated below. It is vital to read the entire instruction manual carefully and make sure to understand it all. Do not skip any steps. Each of these steps is very important and must be completed by you.

Rigd virus?

The Rigd ransomware is a kind of malware that encrypts your documents and then forces you to pay to restore them. Note that Djvu/STOP ransomware family was first revealed and analyzed by virus analyst Michael Gillespie.

Rigd virus is basically similar to other representatives of DJVU ransomware like: Koom, Wiot, Wiot. This virus encrypt all popular file types and adds its own “.rigd” extension into all files. For instance, the file “1.jpg”, will be changed into “1.jpg.rigd“. As soon as the encryption is successfully accomplished, virus drops a specific text file “_readme.txt” and puts it into all folders that contain the modified files.

The image below gives a clear vision of how the files with the “.rigd” extension look like:

This message asking payment is for restore files via decryption key:

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

If Rigd worked in online mode, you can’t gain access to the AES-256 key. It is stored on a distant server owned by the frauds who promote the Rigd ransomware.

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 e-mail ().

The message by the ransomware states the following information:

ATTENTION!

Don't worry. You can return all your files!

All your files like photos, databases, documents, and others are encrypted with the strongest encryption and unique key.
The only method of recovering files is to purchase a decrypt tool and unique key for you.
This software will decrypt all your encrypted files.

What guarantees do you have?

You can send one of your encrypted files from your PC, and we decrypt it for free.
But we can decrypt only one file for free. The file must not contain valuable information.

Do not pay for Rigd!

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

I definitely recommend that you do not contact these frauds 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 apply a similar set of actions for generating 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 losing your valuable data is to make backups of your crucial files regularly.

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

For instance, the backup may be kept 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 computer is surely not a good idea.
