.GMPF Files Virus How to Remove It

This article explains the issues that occur in case of infection with .GMPF files virus and provides a complete guide on how to remove malicious files and how to potentially recover files encrypted by this ransomware.

.GMPF files virus corrupts valuable data stored on the devices it compromises in order to generate revenue for its owners. As identified by the security researcher Michael Gillespie, this crypto virus belongs to the Matrix ransomware family which was first spotted back in December 2016. An infection with this threat leads to restricted access to important files and heavy system modifications. Encrypted files are renamed with a long sequence of extensions that ends with .GMPF. At this point, the amount of demanded ransom is not stated.

Threat Summary

Name.GMPF Files Virus

.GMPF Files Virus – Distribution

Several common methods could be employed for .GMPF files virus distribution. One of them is the widely used malspam. Hackers use various deceptive email elements to trick users into downloading the ransomware payload. Among the most common ones are spoofed email sender as well as email address, a misleading text message that provokes sense of urgency, file attachment of familiar types such as ZIP or RAR, and URLs that land on corrupted web pages set to cause drive-by download attack.

File attachments are preferred as once opened on the machine, they trigger the ransomware and enable it to corrupt target data. As we mentioned they may come in different file formats – documents (with malicious macros), PDFs (with malicious JavaScript code), archived files in ZIP or RAR format, and other frequently used types of data.

Another technique for .GMPF ransomware distribution is through various websites for software downloads. Different P2P networks like BitTorrent could be also used to deliver the ransomware payload on computer systems. Some iterations of the so-called

Facebook virus could be spreading this .GMPF Matrix strain as well.

.GMPF Files Virus – Overview

A ransomware named after the specific extension it uses to mark encrypted files – .GMPF has been spotted in the wild. As identified by security researchers, it is another strain of

Matrix ransomware family. Some of its recently detected predecessors are associated with the extensions .THDA, .NOBAD, and .GMAN.

Like previous versions .GMPF files virus aims to reach data encryption stage when it can utilize a built-in encryption module and corrupts all your important files. This is possible only after the ransomware plagues some essential system settings, processes and components. To do this the payload file of .GMPF crypto virus may be configured to connect to its command and control server where some additional infection files could be downloaded from.

After it establishes all needed malicious files on the system, .GMPF starts to execute them in a predefined order that leads the attack to its end. Harmful files could affect some legitimate system processes whose functionalities serve for the utilization of some harmful changes. Once the ransomware implements its changes on system settings it could continue with the next stage of the attack which is data corruption. Have in mind that as long as .GMPF is running on your system you cannot use the infected PC in a normal way. Only by deleting all malicious files and objects you could use it in a secure manner again.

Yet another event that occurs during the infection process is the display of an associated ransom note that informs you about the presence of .GMPF, its impact and its owners’ demands. As in the common case, hackers are likely to demand a ransom in Bitcoins for file decryption. However, they could skip sending you a working decryption solution even after a ransom payment. That’s why we advise you to avoid their instructions and try to fix your system and data with the help of alternative and secure approaches.

.GMPF Files Virus – Encryption Process

This strain of Martix ransomware is believed to use a combination of two sophisticated cipher algorithms – AES-128 + RSA-2048 to corrupt target files. So during the encryption process, the ransomware changes the original code of predefined types of files with the help of these two algorithms in order to make them completely inaccessible.

It is likely that all of the following types of files will be corrupted by .GMPF crypto virus after it runs its built-in encryption module:

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

Following encryption corrupted files remain inaccessible until an efficient data recovery solution is put into use. They could be all recognized by the distinctive string of extensions appended to their original names:

  • [GetMyPass@qq.com].{user ID – random letters and numbers}.GMPF

The unique decryption key which is generated during the encryption process is soon transferred to hackers’ controlled server so that you cannot access it without contacting them.

Remove .GMPF 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 .GMPF 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.

The automatic approach enables you to check the infected system for ransomware files and remove them with a few clicks after the scan. Reliable anti-malware program is also one of the best ways to protect the PC from ransomware. Additional security layer that will prevent you from ransomware attacks is

anti-ransomware tool.

If you want to understand how to fix .GMPF files without paying the ransom make sure to read carefully all the details mentioned in the step “Restore files” from the guide below. Beware that before recovery process you should back up all encrypted files to an external drive in order to prevent their irreversible loss.

    Hello NguyenPham,

    Unfortunately, at this point, there is no remedy for that ransomware family (Matrix). What we could advise you, however, is to transfer all your encrypted files to an external drive and keep them safe as malware researchers could make a decryption tool at some point. Meanwhile, have you tried any of the methods listed in step “4. Try to Restore files encrypted by .GMPF files virus” ?
