An infection with the Repp ransomware virus leads to serious issues that affect the overall system security. The most unpleasant consequence is the encryption of valuable files. This removal guide shows illustrated instructions on how to get rid of Repp virus infection.


Repp Ransomware Removal

According to information shared by security researchers, the so-called Repp virus is a ransomware that is based on the code of one of the biggest ransomware families called STOP/Djvu. Numerous strains of this ransomware family have appeared on the malware scene since the original variant was released in the wild.

Like its predecessors, the Repp virus is designed to corrupt essential system settings with the goal to pass through several attack stages. As a consequence, the ransomware leaves all important files encrypted and renamed with the .repp extension. Then it extorts a ransom fee for the decryption of encrypted personal files. The extortion is realized via ransom message. This message can be found in the text file _readme.txt

In the beginning, the ransomware corrupts system settings that will help it to evade detection and hide malicious files. Beware that when an infection with Repp ransomware occurs, some major registry keys like RUN and RUNONCE are contaminated. The reason is that their functionalities can enable it to launch malicious files every time the infected system is started. The end of the attack takes place when a ransom message pop-ups on the screen to extort a ransom fee from victims.

Repp Virus – More About the Infection Process

As you have just understood Repp virus is called to a data locker ransomware that belongs to one of the biggest ransomware families STOP/Djvu. The name of this strain is a derivative of the malicious extension .Repp it appends to files it encrypts. The same goes with the names of its recently discovered pedecesors Npsg virus, Btos virus, Zobm virus and Reha virus.

Techniques like spam emails, email attachments, hacked web pages, and corrupted freeware installers are likely to be utilized for the spread of Repp ransomware virus. Since malspam propagation technique enables hackers to spread their malicious code on a large scale it is considered to be the main one. Malwpam technique (massive email spam campaigns that try to deliver malicious code) has its traits. So how to recognize an email that endangers the overall security of your PC and data stored on its drives? First: Does the email have an attached file of common type or a link presented as a button, an image, a plain URL or another clickable form? If the answer is positive then avoid interacting with these elements. If you believe that you should view the content then scan the file / link with online malware scanners like VirusTotal. The results will provide information about the security level of the content.

Among the most popular Windows file types that are used by malware are executable files, documents and other Microsoft Office files, application files, script files, PDFs, temporary files and other.

.repp File Extension

All initial malicious changes performed by the ransomware enable it to reach the encryption stage. During this stage, the ransomware launches a built-in cipher module to corrupt personal files. Specific folders are scanned for commonly used types of files as they are likely to store valuable user data. Every time a target file is detected, its code is transformed via a strong cipher algorithm. As a result of encryption, corrupted files receive the malicious extension .repp

Unfortunately, encrypted files remain inaccessible after encryption. The malicious file extension .Repp may appear at the end of document, music, project, database, image, video, backup, archive, and audio files.

In fact, the end goal of Repp ransomware is to blackmail its victims into paying a ransom fee to hackers who stand behind the attacks. A ransom note file called _readme.txt informs that the decryption of corrupted files can be realized after a payment of $490 – $980 ransom fee. The full content of this file can be seen below:

      Hello Achille,

      If you are unsure whether or not a certain registry value is related to the virus we recommend that you don’t edit and/or delete it. You can certainly try and see if this resolves any issues however we do recommend that you backup your system before doing so.
