Utjg – Ransomware

Utjg is a malicious software working as common ransomware. Michael Gillespie, the well-known malware researcher, first found this new name in the DJVU ransomware family.

Utjg was created for the sole function to encrypt all popular file types. Rationally, as soon as the file encryption is effectively achieved, the users are unable to get access to them. Utjg virus adds its own “.utjg” to all the encrypted data. For instance, the file “price_list.xls”, as soon as modified by Utjg, will be titled as “price_list.xls.utjg”. As soon as the encryption is achieved, Utjg puts its own distinct text file (_readme.txt) into all the folders that keep the encrypted files.

The alert stated by text file requesting the random os really similar to the notices given by other ransomware hazards belonging to the DJVU family. The warning essentially indicates that the files have been encrypted and the only solution to get access to it is to use an unique standalone key. Regretfully, this declaration is definitely true.

The technique to secure the files utilized by Utjg is not totally researched. However, there is no doubt that each computer system owner may be issued a special decryption key, which is definitely unique. It is exceptionally tough to recover the data without the proper key in location.

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

message from Utjg virus

One more peculiarity of the Utjg virus is that the users are not able to get access to the key. The decrypting key is hosted on a special server under the total control by the scoundrels who have actually launched the Utjg infection into the web. In order to get the key and bring back the crucial information, the users are informed to get in touch with the frauds by means of email or by telegram and to pay the ransom in the quantity of $980.

The message also says that the people must get in touch with the Utjg authors within 72 hours upon the minute of the information file encryption. The alert indicates that by doing so individuals will get a 50% discount, for that reason, the ransom quantity drops down to $490.

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

Likewise, we urge you not to call the frauds as they advise. Do not move loan into their wallets. There are no applications that could crack the Utjg virus or restore the data for free. Therefore, the only appropriate decision is to bring back the data from possible backups (if readily available).
