Repg Virus Ransomware

Repg is a harmful software functioning as common ransomware. Michael Gillespie, the well-known malware researcher, very first discovered this new name in the DJVU ransomware family.

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

The message specified by document asking for the random os extremely similar to the notifications provided by other ransomware hazards belonging to the DJVU family. The warning basically 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 declaration is absolutely true.

The method to secure the files used by Repg is not completely looked into. However, there is no doubt that each computer owner may be provided a special decryption key, which is absolutely unique. It is exceptionally difficult to recuperate the data without the proper type 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 Repg ransomware is that the users are not able to get access to the key. The decrypting key is hosted on a special server under the complete control by the scoundrels who have actually released the Repg virus into the web. In order to obtain the key and bring back the crucial information, the users are told to contact the frauds via e-mail or by telegram and to pay the ransom in the quantity of $980.

The message likewise says that the people should call the Repg authors within 72 hours upon the minute of the data file encryption. The alert suggests that by doing so individuals will get a 50% discount, therefore, the ransom quantity drops down to $490.

No matter what the amount of the ransom is, we strongly advise that you do not pay the ransom. There is no guarantee that these online crooks will keep their pledges, so they may not care at all what the victims feel about the encryption, even when the quantity of the ransom is gotten into their accounts. Thus, paying ransom often does not lead to an effective healing. So, the users might just lose their money for nothing.

Similarly, we advise you not to get in touch with the frauds as they instruct. Do not transfer cash into their wallets. There are no applications that could split the Repg virus or restore the information at no charge. Therefore, the only appropriate decision is to restore the data from possible backups (if readily available).
