Pola Virus (. Pola File) Ransomware — ✅Remove & Decrypt Files

Pola virus?

Pola

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

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

Pola virus is similar to other the same DJVU family: Qlkm, Wbxd, Coos. This virus encrypt all popular file types and adds its particular “.pola” extension into all files. For instance, the file “1.jpg”, will be changed into “1.jpg.pola“, “2.jpg” to “2.jpg.jpg.pola“. As soon as the encryption is successfully accomplished, Pola generates a specific text file “_readme.txt” and drop it into all folders that contain the modified files.

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

This text asking payment is for restore files 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 ransomware family is AES-256. So, if your files got encrypted with an online decryption key, which is totally unique. The sad reality is that it is impossible to decrypt the files without the unique key.

In case if Pola worked in online mode, it is impossible for you to gain access to the AES-256 key. It is stored on a remote server owned by the frauds who promote the Pola virus.

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 ().

The message by the Pola ransomware states the following information:

Do not pay for Pola!

_readme.txt file also indicates that the computer owners must get in touch with the Pola representatives during 72 hours starting from the moment of files where 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). 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 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 with 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 regularly make backups of your crucial files.

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, 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 wise idea.
