Ybtn – General Info

Ybtn is a harmful software application functioning as common ransomware. Michael Gillespie, the popular virus researcher, very first found this new name in the DJVU ransomware family.

Ybtn was developed for the sole purpose to encrypt all popular file types. Realistically, as quickly as the encryption is effectively achieved, the users are unable to get access to them. Ybtn virus includes its own “.ybtn” to all the encrypted data. For example, the file “price_list.xls”, when crypted by Ybtn, will be entitled as “price_list.xls.ybtn”. As soon as the file encryption is achieved, Ybtn puts its own distinct text file (_readme.txt) into all the folders that keep the encrypted files.

The alert specified by text file requesting the random os very similar to the alerts offered by other ransomware threats coming from the DJVU family. The warning basically indicates that the data has been encrypted and the only option to get access to it is to use a distinct standalone key. Regretfully, this statement is definitely true.

The approach to secure the files utilized by Ybtn is not completely researched. However, there is no doubt that each computer system owner may be released a special decryption key, which is definitely unique. It is extremely difficult to recuperate the information without the suitable type in location.

“Don’t worry, you can return all your files!”, from text file message:

One more peculiarity of the Ybtn infection is that the users are not able to get access to the key. The decrypting key is hosted on an unique server under the total control by the scoundrels who have actually released the Ybtn infection into the world wide web. In order to get the key and bring back the important information, the users are informed to connect with the frauds via e-mail or by telegram and to pay the ransom in the amount of $980.

The message also says that the people ought to contact the Ybtn authors within 72 hours upon the minute of the data encryption. The alert indicates that by doing so the people will get a 50% discount rate, therefore, the ransom quantity falls to $490.

No matter what the amount of the ransom is, we strongly encourage that you do not pay the ransom. There is no warranty that these online criminals will keep their promises, so they might not care at all what the victims feel about the encryption, even when the amount of the ransom is received into their accounts.

Likewise, we urge you not to call the frauds as they advise. Do not move cash into their wallets. There are no applications that might split the Ybtn ransomware or restore the information at no cost. For that reason, the only right choice is to restore the information from possible backups (if available).
