Ytbn Virus (. Ytbn File) Ransomware — Remove & Decrypt Data

Ytbn virus?

The Ytbn ransomware is a specific kind of threat that encrypted your files and then forces you to pay for them. Note that Djvu/STOP ransomware family was first revealed and discovered by virus analyst Michael Gillespie.

Ytbn virus is similar to other DJVU ransomware like: FDCZ, Ekvf, Enfp. This virus encrypt all common file types and adds its particular “.ytbn” extension into all files. For example, the file “1.jpg”, will be changed into “1.jpg.ytbn“. As soon as the encryption is accomplished, virus generates a specific message 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 “.ytbn” extension look like:

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

The cryptography algorithm used by DJVU/STOP virus is AES-256. So, if your files 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.

In case if Ytbn worked in online mode, it is impossible for you to gain access to the AES-256 key. It is stored on a distant server owned by the frauds who distibute the Ytbn 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 ().

The message by the ransomware states the following information:

Do not pay for Ytbn!

_readme.txt file also indicates that the computer owners must get in touch with the Ytbn 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). Yet, stay away from paying the ransom!

I strongly recommend 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 PC is surely not a good idea.
