The Kmbgdftfgdlf virus falls under the Xorist ransomware family. Malware of such sort encrypts all user’s data on the computer (photos, documents, excel tables, audio files, videos, etc) and adds its own extension to every file, creating the КАК РАСШИФРОВАТЬ ФАЙЛЫ.txt files in every directory which contains the encrypted files.
Kmbgdftfgdlf virus: what is known so far?
☝️ A scientifically accurate designation for the Kmbgdftfgdlf would be “a Xorist family ransomware malicious agent”.
Kmbgdftfgdlf will append its extra .kmbgdftfgdlf extension to the title of each encoded file. For example, a file named “photo.jpg” will be changed to “photo.jpg.kmbgdftfgdlf”. Likewise, the Excel table named “table.xlsx” will be changed to “table.xlsx.kmbgdftfgdlf”, and so forth.
In every folder containing the encoded files, a КАК РАСШИФРОВАТЬ ФАЙЛЫ.txt file will be created. It is a ransom money memo. Therein you can find information on the ways of contacting the racketeers and some other information. The ransom note usually contains instructions on how to purchase the decryption tool from the racketeers. That is it.

How did my machine catch Kmbgdftfgdlf ransomware?
There are many possible ways of ransomware infiltration.
There are currently three most popular ways for evil-doers to have ransomware planted in your digital environment. These are email spam, Trojan infiltration and peer file transfer.
If you open your inbox and see emails that look just like notifications from utility services providers, postal agencies like FedEx, Internet providers, and whatnot, but whose addresser is unknown to you, beware of opening those emails. They are very likely to have a harmful item attached to them. So it is even more dangerous to open any attachments that come with letters like these.
Another option for ransom hunters is a Trojan file scheme. A Trojan is a program that gets into your computer pretending to be something else. For example, you download an installer for some program you want or an update for some program. But what is unboxed reveals itself a harmful agent that compromises your data. Since the installation wizard can have any name and any icon, you’d better be sure that you can trust the resource of the files you’re downloading. The optimal way is to use the software companies’ official websites.
As for the peer-to-peer file transfer protocols like BitTorrent or eMule, the danger is that they are even more trust-based than the rest of the Web. You can never guess what you download until you get it. Our suggestion is that you use trustworthy websites. Also, it is a good idea to scan the directory containing the downloaded files with the antivirus as soon as the downloading is finished.
How to remove the Kmbgdftfgdlf virus?
It is crucial to inform you that besides encrypting your files, the Kmbgdftfgdlf virus will most likely deploy Vidar Stealer on your computer to get access to credentials to various accounts (including cryptocurrency wallets). The mentioned spyware can extract your credentials from your browser’s auto-filling cardfile.
Sometimes racketeers would unblock several of your files so you know that they really have the decryption program. Since Kmbgdftfgdlf virus is a relatively recent ransomware, anti-malware developers have not yet found a method to reverse its work. However, the decoding tools are frequently upgraded, so the effective countermeasure may soon be available.
Understandably, if the malefactors do the job of encrypting victim’s critical data, the hopeless person will probably fulfill their demands. However, paying a ransom gives no guarantee that you’re getting your blocked information back. It is still risky. After getting the money, the racketeers may deliver a wrong decryption key to the injured party. There were reports of ransomware developers simply disappearing after getting the ransom without even writing back.
The best safety measure against ransomware is to have a system restore point or the copies of your essential files in the cloud storage or at least on an external drive. Of course, that might be not enough. Your most important thing could be that one you were working on when it all went down. Nevertheless, it is something. It is also wise to scan your drives with the antivirus program after the system is rolled back.
Kmbgdftfgdlf is not the only ransomware of its kind, since there are other specimens of ransomware out there that act in the same manner. Examples of those are Nifr, Niwm, Boty, and some others. The two main differences between them and the Kmbgdftfgdlf are the ransom amount and the method of encryption. The rest is almost identical: files become encrypted, their extensions changed, ransom notes are created in every directory containing encoded files.
Some fortunate users were able to decode the arrested files with the help of the free software provided by anti-ransomware experts. Sometimes the racketeers accidentally send the decoding key to the victims in the ransom readme. Such an epic fail allows the user to restore the files. But obviously, one should never expect such a chance. Make no mistake, ransomware is a criminals’ technology to pull the money out of their victims.
How сan I avert ransomware infiltration?
Kmbgdftfgdlf ransomware doesn’t have a endless power, neither does any similar malware.
You can armour your PC from ransomware injection within three easy steps:
- Ignore any letters from unknown mailers with unknown addresses, or with content that has likely no connection to something you are expecting (can you win in a lottery without even taking part in it?). If the email subject is more or less something you are expecting, scrutinize all elements of the suspicious letter with caution. A hoax letter will always have a mistake.
- Avoid using cracked or untrusted programs. Trojan viruses are often distributed as an element of cracked products, most likely as a “patch” which prevents the license check. Understandably, potentially dangerous programs are very hard to distinguish from reliable software, because trojans may also have the functionality you need. You can try to find information about this software product on the anti-malware message boards, but the best solution is not to use such programs at all.
