GMPF virus Removal Guide
What is GMPF ransomware?
GMPF ransomware is a virus that corrupts data stored on infected devices and demands ransom
GMPF ransomware is a cryptovirus that belongs to a notorious family of ransom-demanding threats.
GMPF ransomware — cryptovirus that employs both AES and RSA encryption 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.
[GetMyPass@qq.com].user ID (random letters and numbers).GMPF
|Encryption method||AES-128 + RSA-2048|
|Symptoms||Adds file marker to encoded files, makes data inaccessible and demands ransom in cryptocurrency|
|Distribution||Spam email attachments|
|Elimination||Use ReimageIntego for GMPF ransomware removal|
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: [GetMyPass@qq.com].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. 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 YOUR FILES HAVE BEEN ENCRYPTED!
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!
HURRY UP OR YOU WILL BE ARRESTED!!!
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 ReimageIntego and then use data recovery tools. Researchers 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 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:
- 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.

How to prevent from getting GMPF ransomware
Choose a proper web browser and improve your safety with a VPN tool
Online spying has got momentum in recent years and people are getting more and more interested in how to protect their privacy online. One of the basic means to add a layer of security – choose the most private and secure web browser. Although web browsers can't grant full privacy protection and security, some of them are much better at sandboxing, HTTPS upgrading, active content blocking, tracking blocking, phishing protection, and similar privacy-oriented features. However, if you want true anonymity, we suggest you employ a powerful Private Internet Access VPN – it can encrypt all the traffic that comes and goes out of your computer, preventing tracking completely.
Lost your files? Use data recovery software
While some files located on any computer are replaceable or useless, others can be extremely valuable. Family photos, work documents, school projects – these are types of files that we don't want to lose. Unfortunately, there are many ways how unexpected data loss can occur: power cuts, Blue Screen of Death errors, hardware failures, crypto-malware attack, or even accidental deletion.
To ensure that all the files remain intact, you should prepare regular data backups. You can choose cloud-based or physical copies you could restore from later in case of a disaster. If your backups were lost as well or you never bothered to prepare any, Data Recovery Pro can be your only hope to retrieve your invaluable files.
