.GMAN Files Virus – How to Remove It and Restore Data

!README_GMAN!.rtf GMAN files virus ransom note sensorstechforum

This is an article that provides specific details on .GMAN files virus as well as a detailed guide with removal steps and alternative data recovery approaches.

The so-called .GMAN crypto virus is a recently discovered strain of Matrix ransomware. As a typical data locker ransomware, this crypto virus could compromise your computer system in order to encrypt valuable files and extort a ransom from you. Once it corrupts target files it marks them with the specific .GMAN. Seeing this extension appended to the names of your files means that you won’t be able to access the data they store before you apply an efficient solution that will restore them. Beware that even a successful ransom payment does not guarantee the decryption of your files. So we advise you to consider the removal of this nasty threat and try to restore files with the help of alternative methods.

.GMAN Files Virus – Distribution

The infection code of .GMAN files virus could be spread is via malspam campaigns. In fact, email campaigns are among the most common spread techniques used by ransomware authors. Here you could see some of the traits that could help you to recognize such emails and prevent your system from being affected by malicious code:

  • A presented link that lands on web page compromised by hackers. Such page could be set to download and execute the ransomware payload directly on the computer of each user who got tricked into visiting it.
  • A file attachment of familiar file type such as document (.doc, .PDF, .docx, .xlsx, etc.) archive (.rar, .zip, .7z, etc.) or other. Corrupted files could be masked as legitimate ones and in order to trick you into running the malicious code embedded in them they may be set to open after you perform several steps.

Other methods like malicious exploit kits, fake updates notifications and infected installers of third-party programs may be also used to trick you into running the infection code and plague your system.

.GMAN Files Virus – Overview

The so-called .GMAN files virus has been identified to belong to Matrix ransomware family.

An infection with this strain of Matric ransomware is triggered by a payload file that contains code that triggers predefined commands. Once it is started on the system the ransomware becomes able to initiate a sequence of malicious actions that plague essential system components and lead the attack to its end.

One of the main activities performed in the beginning is the creation of additional malicious files that support further compromises. What its associated files aim to do is to contaminate major system components and their settings. What’s more some of them could be configured to manipulate legitimate system processes that will enable the ransomware to prevent being detected by active security tools.

Soon after the ransomware completes system and data modifications it drops a ransom note file called !README_GMAN!.rtf in one or several folders. The text presented by this message reveals you the presence of the ransomware and blackmails you into paying hackers certain ransom for a decryption solution.

.GMAN Files Virus – Encryption Process

Being a strain of Matric ransomware family .GMAN crypto virus applies a combination of sophisticated cipher algorithms during the encryption process. During this process the ransomware transforms the original code of target files in order to restrict the access to stored data. Unfortunately, an infection with this crypto virus could lead to the corruption of valuable files including but not limiting to your:

  • Audio files
  • Video files
  • Document files
  • Image files
  • Backup files
  • Banking credentials, etc

Upon encryption, all corrupted files have the extension .GMAN appended to their original names. During encryption process, the ransomware generates a decryption key that is supposedly able to recover encrypted files to their original state. However, you should not believe hackers as they could only trick you into paying them a ransom for a broken decryption key that won’t work for your .GMAN files.

Remove .GMAN Files Virus and Restore Data

Below you could find how a step-by-step removal guide that may be helpful in attempting to remove this .GMAN files virus. The manual removal approach demands practice in recognizing traits of malware files. Beware that ransomware is a threat with highly complex code that plagues not only your files but your whole system. So it should be secured properly before it could be used regularly again.
