Rezm Virus Removal Guide (+Decrypt .rezm files)

Rezm Virus Ransomware

Rezm is a harmful software application working as typical ransomware. Michael Gillespie, the popular virus researcher, first found this new name in the DJVU ransomware family.

Rezm was developed for the sole purpose to encrypt all popular file types. Logically, as quickly as the encryption is effectively accomplished, the users are not able to get access to them. Rezm ransomware includes its own “.rezm” to all the encrypted files. For instance, the file “price_list.xls”, once modified by Rezm, will be titled as “price_list.xls.rezm”. As soon as the encryption is accomplished, Rezm puts its own unique text document (_readme.txt) into all the folders that store the encrypted files.

The message specified by document requesting the random os really comparable to the notifications offered by other ransomware hazards belonging to the DJVU family. The warning essentially shows that the information has 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 approach to encrypt the files utilized by Rezm is not totally researched. However, there is no doubt that each computer owner may be released a special decryption key, which is absolutely unique. It is exceptionally difficult to recover the information without the suitable type in place.

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

message from Rezm virus

One more peculiarity of the Rezm infection is that the users are unable to get access to the key. The decrypting key is hosted on an unique server under the complete control by the crooks who have actually released the Rezm infection into the world wide web. In order to obtain the key and bring back the crucial data, the users are informed to get in touch with the frauds via email or by telegram and to pay the ransom in the quantity of $980.

The message likewise states that individuals must contact the Rezm authors within 72 hours upon the moment of the information file encryption. The alert shows that by doing so the people 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 crooks will keep their promises, so they may not care at all what the victims feel about the encryption, even when the amount of the ransom is received into their accounts. Thus, paying ransom typically does not result in a successful recovery. So, the users might simply lose their money for nothing.

Likewise, we advise you not to contact the frauds as they instruct. Do not move loan into their wallets. There are no applications that could split the Rezm virus or bring back the data for free. For that reason, the only proper decision is to bring back the data from possible backups (if available).
