removal by Alice Woods - - | Type: Ransomware

GMPF ransomware is a virus that corrupts data stored on infected devices and demands ransom

GMPF ransomware

GMPF ransomware — cryptovirus that employs both AES and RSA encryption[1] algorithms to make users' data useless. Discovered in October 2018, this threat is the latest addition to Matrix ransomware family that was first spotted at the end of 2016. There is not much information discovered about GMPF ransomware yet, but it is known that the virus adds .GMPF file extension to encrypted data. Since this cyber threat focuses on getting money from affected users, immediately after locking victim's data, it develops a ransom note and places the file on every folder in the system containing encoded data. Based on previous versions, this ransom message should be placed in TXT or RTF file.

It is believed that GMPF ransomware virus, as the previous versions in the family, is using a sophisticated encryption method which is combined of AES-128 and RSA-2048 algorithms. During this process, the virus changes the original code of the file and makes data inaccessible with these two algorithms. The additional file marker is written in the following pattern: [].user ID – random letters and numbers.GMPF. The file extension is placed to indicate which ones are encoded.

Encrypted files become corrupted and inaccessible until decryption. However, we do not recommend paying the ransom for the alleged decryption cybercriminals state they can perform. It may lead to more severe damage or even permanent data or money loss.[2] Hackers may disappear after payment is done. 

The unique keys formed during the whole encryption process transferred to hackers' server and cannot be reached by anyone else. Since there is no official decryption tool developed by security specialists your only choice is to restore data or replace files from a backup.

At the time of writing, there is not much information about the particular variant and the ransom note or ransom amount. However, there is a tendency to form ransom messages in a similar pattern for each version in the family. GMPF ransomware ransom note might look similar:


All of important data on this computer was encrypted with strong RSA-2048 algorithm due to the violation of the federal laws of the United States of America! (Article 1, Section 8, Clause 8; Article 2010 of the Criminal Code of U.S.A provides for a deprivation of liberty for four to twelve years.)

Following violations were detected:
Your IP address was used to visit websites containing pornography, child pornography, zoophilia and child abuse!

To unlock your files you have to pay the penalty!

You have only 96 hours to recover your personal data! After this time your unique key will be deleted and files decryption will become impossible!
Each 12 hours the payment size will be automatically increased by 100$!
You must pay the payment through the Bitcoin Wallet.
To get your unique key and unlock files, you should send the following code:
to our agent emails:
Your will receive all necessary instructions!


The ransom note composed for particular GMPF ransomware might differ from any other version of crypto-demanding threats, but the primary purpose of this message is to inform the victim about the following steps and solutions for the whole attack. Also, often ransomware developers display instructions on payment methods to make the ransom payment easier. The ransom amount might also differ, but you shouldn't consider paying these hackers at all.

You need to remove GMPF ransomware from the system entirely and do not contact these cybercriminals. When your device is clean, you can then perform a file recovery using software or data backups. It is the safes way even though not all of your files can be restored. If you enter the external drive on the infected device ransomware encrypts additional data.

If you have no data that can replace encoded files you need to perform GMPF ransomware removal using anti-malware like Reimage Reimage Cleaner Intego and then use data recovery tools. Researchers[3] note that you should double-check before adding any new software or devices on the system. Scan the device fully and get rid of any possible threats. Check virus elimination tips down below.   GMPF ransomware virusGMPF ransomware is a cyber threat that focuses on data encryption. Using army-grade encryption algorithms GMPF ransomware locks your data and demands to pay.

Deceptive email elements used to trick people into downloading malware

Spam email techniques are the most commonly used to spread malware including ransomware. Hackers use malspam widely to distribute their malicious products all over the world. Misleading messages, familiar company names or types of documents, subject lines suggesting the urgency can trick people into believing everything. 

File attachments as commonly used MS Excel or Word files look legitimate enough to download them on the device without thinking. However, once opened these files trigger the virus payload and enable the malicious functionality of a file or load the direct ransomware payload on the system. File attachments may come in various formats:

  • PDF documents that include malicious JavaScript code;
  • archives in ZIP or RAR format;
  • documents filed with malicious macros. 

You can avoid this cyber infection if you scan files before downloading and opening them on your computer. Also, cleaning suspicious emails from the email box can be beneficial for the general security of your system. Additionally scanning the system with anti-malware ensures that there is no unwanted applications and malware on the PC.

Guide which is presented above is supposed to help you remove GMPF from your computer. To recover your encrypted files, we recommend using a detailed guide prepared by security experts.

If your files are encrypted by GMPF, you can use several methods to restore them:

Since GMPF ransomware encrypt your files you need to restore them using Data Recovery Pro

Data Recovery Pro can help with encrypted or accidentally deleted files. Try this method as an alternative for data backups

  • Download Data Recovery Pro;
  • Follow the steps of Data Recovery Setup and install the program on your computer;
  • Launch it and scan your computer for files encrypted by GMPF ransomware;
  • Restore them.

Use Windows Previous Versions feature as another method of file recovery

However, make sure that System Restore was enabled before

  • Find an encrypted file you need to restore and right-click on it;
  • Select “Properties” and go to “Previous versions” tab;
  • Here, check each of available copies of the file in “Folder versions”. You should select the version you want to recover and click “Restore”.

ShadowExplorer is yet another alternative for file restoring from a backup

If GMPF ransomware encrypted your files but left Shadow Volume Copies, you could use ShadowExplorer for the job of data recovery

  • Download Shadow Explorer (;
  • Follow a Shadow Explorer Setup Wizard and install this application on your computer;
  • Launch the program and go through the drop down menu on the top left corner to select the disk of your encrypted data. Check what folders are there;
  • Right-click on the folder you want to restore and select “Export”. You can also select where you want it to be stored.

Decryption tool is not available

Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from GMPF and other ransomwares, use a reputable anti-spyware, such as Reimage Reimage Cleaner Intego, SpyHunter 5Combo Cleaner or Malwarebytes

Access your website securely from any location

When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. It is a hassle when your website is protected from suspicious connections and unauthorized IP addresses.

The best solution for creating a tighter network could be a dedicated/fixed IP address. If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for server or network manager that need to monitor connections and activities. This is how you bypass some of the authentications factors and can remotely use your banking accounts without triggering suspicious with each login. 

VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world. It is better to clock the access to your website from different IP addresses. So you can keep the project safe and secure when you have the dedicated IP address VPN and protected access to the content management system.

Backup files for the later use, in case of the malware attack

Computer users can suffer various losses due to cyber infections or their own faulty doings. Software issues created by malware or direct data loss due to encryption can lead to problems with your device or permanent damage. When you have proper up-to-date backups, you can easily recover after such an incident and get back to work.

It is crucial to create updates to your backups after any changes on the device, so you can get back to the point you were working on when malware changes anything or issues with the device causes data or performance corruption. Rely on such behavior and make file backup your daily or weekly habit.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware occurs out of nowhere. Use Data Recovery Pro for the system restoring purpose.
