Jycx Virus – Details

Jycx is a destructive software application functioning as common ransomware. Michael Gillespie, the widely known virus researcher, first found this new name in the DJVU ransomware family.

Jycx was created for the sole purpose to encrypt all popular file types. Realistically, as soon as the encryption is effectively achieved, the users are unable to get access to them. Jycx virus adds its own “.jycx” to all the encrypted files. For instance, the file “price_list.xls”, as soon as modified by Jycx, will be titled as “price_list.xls.jycx”. When the file encryption is accomplished, Jycx puts its own unique text document (_readme.txt) into all the folders that keep the encrypted files.

The message mentioned by _readme.txt requesting for the random os really comparable to the alerts provided by other ransomware threats coming from the DJVU family. The caution generally shows that the files have been secured and the only solution to get access to it is to use a special standalone key. Regretfully, this statement is definitely real.

The approach to encrypt the files utilized by Jycx is not entirely researched. Nevertheless, there is no doubt that each computer system owner might be issued an unique decryption key, which is absolutely special. It is very difficult to recover the data without the appropriate key in location.

“Don’t worry, you can return all your files!”, from _readme.txt message:

Don't worry, you can return all your files! virus

One more peculiarity of the Jycx infection 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 criminals who have actually launched the Jycx ransomware into the web. In order to acquire the key and bring back the crucial data, the users are told to connect with the scams through email or by telegram and to pay the ransom in the quantity of $980.

The message likewise states that the people must get in touch with the Jycx authors within 72 hours upon the minute of the data encryption. The alert indicates that by doing so individuals will get a 50% discount rate, for that reason, the ransom amount falls to $490.

No matter what the quantity of the ransom is, we strongly encourage that you do not pay the ransom. There is no assurance that these online scoundrels will keep their promises, so they may not care at all what the victims feel about the file encryption, even when the quantity of the ransom is received into their accounts. For this reason, paying ransom frequently does not result in an effective healing. So, the users may simply lose their money for absolutely nothing.

Likewise, we advise you not to contact the frauds as they instruct. Do not transfer loan into their wallets. There are no applications that might split the Jycx virus or restore the information for free. For that reason, the only appropriate choice is to bring back the information from possible backups (if offered).
