Byya Virus Removal Guide (+Decrypt .byya files)

Byya Virus Ransomware

Byya is a harmful software application working as common ransomware. Michael Gillespie, the popular malware researcher, very first discovered this new name in the DJVU ransomware family.

Byya was created for the sole function to encrypt all popular file types. Logically, as soon as the encryption is successfully accomplished, the users are not able to get access to them. Byya ransomware includes its own “.byya” to all the encrypted files. For example, the file “price_list.xls”, when modified by Byya, will be entitled as “price_list.xls.byya”. When the file encryption is achieved, Byya puts its own unique text document (_readme.txt) into all the folders that save the encrypted files.

The message specified by document asking for the random os very comparable to the notices given by other ransomware risks belonging to the DJVU family. The caution basically indicates that the information has been encrypted and the only option to get access to it is to use a special standalone key. Regretfully, this declaration is definitely real.

The approach to encrypt the files used by Byya is not totally looked into. However, there is no doubt that each computer system owner might be issued a special decryption key, which is definitely special. It is extremely hard to recuperate the information without the suitable type in place.

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

One more peculiarity of the Byya virus is that the users are unable to get access to the key. The decrypting key is hosted on an unique server under the total control by the scoundrels who have launched the Byya virus into the web. In order to acquire the key and restore the important information, the users are informed to contact the frauds through e-mail or by telegram and to pay the ransom in the amount of $980.

The message also says that the people must call the Byya authors within 72 hours upon the moment of the information file encryption. The alert shows that by doing so the people will acquire a 50% discount rate, therefore, the ransom amount falls to $490.

No matter what the quantity of the ransom is, we highly encourage that you do not pay the ransom. There is no warranty that these online scoundrels will keep their pledges, so they may not care at all what the victims feel about the file encryption, even when the quantity of the ransom is gotten into their accounts. For this reason, paying ransom often does not result in a successful recovery. So, the users might just lose their money for absolutely nothing.

Similarly, we prompt you not to contact the frauds as they advise. Do not move money into their wallets. There are no applications that could split the Byya ransomware or bring back the data for free. Therefore, the only right choice is to restore the information from possible backups (if readily available).
