Repp was developed for the sole function to encrypt all popular file types. Logically, as soon as the encryption is effectively accomplished, the users are not able to get access to them. Repp virus includes its own “.repp” to all the encrypted data. For instance, the file “price_list.xls”, when crypted by Repp, will be titled as “price_list.xls.repp”. As soon as the file encryption is accomplished, Repp puts its own special text document (_readme.txt) into all the folders that keep the encrypted files.

The alert stated by document requesting the random os very comparable to the notifications provided by other ransomware risks belonging to the DJVU family. The warning basically shows that the information has been secured and the only service to get access to it is to use a special standalone key. Regretfully, this statement is absolutely true.

The decrypting key is hosted on an unique server under the total control by the criminals who have launched the Repp virus into the world wide web. In order to obtain the key and bring back the important data, the users are told to get in touch with the frauds by means of e-mail or by telegram and to pay the ransom in the amount of $980.
