This article will help you learn more about information about Bmtf ransomware and how to remove it step-by-step.
Bmtf Ransomware
Bmtf ransomware is a vicious malware that originates from the Dharma/CrySiS ransomware family. Once started on a computer operating system, the ransomware interferes with essential settings so that it can encode valuable personal files. By transforming the code of personal files, Bmtf cryptovirus restricts the access to data they store. To make them more recognizable, the ransomware appends a few malicious extensions to their names. The last extension is the .bmtf and actually this Dharma ransomware strain is named after it. At last, Bmtf creates two ransom messages – a lock screen image and a text file, to extort a ransom payment from victims.

More About the Distribution of Bmtf Ransomware and Its Impact
The distribution of threats like Bmtf ransomware is a process that happens via techniques like email spam campaigns, software cracks, fake software update notifications, freeware with compromised installers and malicious web links. All these techniques aim to mislead users that they will download/access trustworthy content. But instead by interacting with those elements, users will execute a malicious payload on their PC.
The moment the payload file of Bmtf virus loads on a computer system, a complex attack of a few stages begins. First, the ransomware creates additional malicious files and then it starts executing them in a predefined order. During this process, the threat implements lots of malicious changes that compromise essential system settings and eventually enable Bmtf to reach and encrypt personal files.
Analyses of the code of Bmtf ransomware reveal that the ransomware is configured to misue the functionalities of some registry keys by adding malicious values entries there. Affected keys may be Run and RunOnceas they are desinged to automatically load certain files and programs on the system. Their directories are:
→ HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce
When the ransomware reaches its main stage – data encryption, it utilizes a built-in cipher module. This module is set to transform parts of the original code of target files with the help of a strong cipher algorithm. Following these changes, you cannot access data stored by corrupted files and they are all marked with a few specific extensions including an ID number, an email address (dfgkbtprz@aol.com) and the .bmtf suffix.
All of the following types of files may be encrypted by the threat:
- Audio files
- Video files
- Document files
- Image files
- Backup files
- Banking credentials, etc
Just like its predecessors including NHLP, Prnds, the Bmtf ransomware aims to become perform malicious activities in the background of all currently running processes. That’s why its presence on the system is revealed after the last infection stage is done.
That’s why the Bmtf ransomware drops its ransom note files at the end of the attack. Once on the system, it executes these files to extort a ransom payment. The purpose of these messages is to trick you into transferring cryptocurrency money to hackers who stand behind Bmtf attacks. We know that data decryption is of paramount importance to you. However, beware that this action does not guarantee the recovery of .bmtf files so you should better avoid it. Here is what the Bmtf’s ransom message may be stating:
All your files have been encrypted!
All your files have been encrypted due to a security problem with your PC. If you want to restore them, write us to the e-mail dfgkbtprz@aol.com

Decryption of your files with the help of third parties may cause increased price (they add their fee to our) or you can become a victim of a scam.
Remove Bmtf Ransomware
The so-called Bmtf ransomware is a threat with a highly complex code that disrupts system security in order to encrypt personal files. Hence the infected system could be used in a secure manner again only after you remove all malicious files and objects created by the ransomware. The steps presented in the ransomware removal guide below will help you with the complete removal process. Beware that the manual ransomware removal is suitable for more experienced computer users. If you don’t feel comfortable with the manual steps navigate to the automatic part of the guide. It is also worth mentioning that personal data remains encrypted even after the complete removal of Bmtf ransomware. Its removal only prevents it from causing further encryptions and security issues.
Step 5 from our Bmtf ransomware removal guide presents alternative data recovery methods that may be efficient for the recovery of encrypted files. Beware that you should make copies of all encrypted files and save them on a flash drive for example before the beginning of the recovery process.
