Ytbn ransomware adds its own “.ytbn” to all the encrypted data. For instance, the file “price_list.xls”, once crypted by Ytbn, will be entitled as “price_list.xls.ytbn”. As soon as the encryption is accomplished, Ytbn puts its own special text document (_readme.txt) into all the folders that keep the encrypted files.
The message stated by text file requesting the random os very comparable to the notices given by other ransomware hazards coming from the DJVU family. The caution generally shows that the information has been secured and the only solution to get access to it is to use an unique standalone key. Regretfully, this declaration is absolutely real.

“Don’t worry, you can return all your files!”, from text file message:
One more peculiarity of the Ytbn ransomware is that the users are unable to get access to the key. The decrypting key is hosted on a special server under the complete control by the crooks who have released the Ytbn virus into the internet. In order to get the key and bring back the essential information, the users are informed to connect with the frauds by means of email or by telegram and to pay the ransom in the quantity of $980.
The message likewise says that individuals need to get in touch with the Ytbn authors within 72 hours upon the minute of the information encryption. The alert suggests that by doing so individuals will acquire a 50% discount rate, therefore, the ransom amount drops down to $490.
