The Kopytzempereebet virus belongs with the ransomware type of malicious agent. Harmful software of this type encrypts all user’s data on the computer (images, documents, excel sheets, audio files, videos, etc) and adds its specific extension to every file, leaving the #Decrypt_files#.txt files in each directory which contains the encrypted files.
What is known about the Kopytzempereebet virus?
☝️ A strictly correct designation for the Kopytzempereebet is “a ransomware-type malicious agent”.
Kopytzempereebet will append its own .KOPYTZEMPEREEBET extension to the title of each encrypted file. For instance, an image named “photo.jpg” will be renamed to “photo.jpg.KOPYTZEMPEREEBET”. In the same manner, the Excel table named “table.xlsx” will become “table.xlsx.KOPYTZEMPEREEBET”, and so on.
In each folder that contains the encoded files, a #Decrypt_files#.txt text file will be created. It is a ransom money memo. Therein you can find information about the ways of contacting the racketeers and some other remarks. The ransom note most probably contains instructions on how to purchase the decryption tool from the Kopytzempereebet developers. That is how they do it.

How did my machine catch Kopytzempereebet ransomware?
There is a huge number of possible ways of ransomware infiltration.
There are currently three most exploited ways for evil-doers to have ransomware working in your digital environment. These are email spam, Trojan injection and peer-to-peer networks.
If you access your mailbox and see emails that look just like notifications from utility services companies, delivery agencies like FedEx, Internet providers, and whatnot, but whose sender is strange to you, be wary of opening those letters. They are most likely to have a viral item attached to them. Thus it is even riskier to download any attachments that come with letters like these.
Another thing the hackers might try is a Trojan virus scheme1. A Trojan is an object that gets into your PC disguised as something else. For instance, you download an installer of some program you want or an update for some software. However, what is unboxed reveals itself a harmful agent that encodes your data. As the update wizard can have any title 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 developers’ official websites.
As for the peer file transfer protocols like torrent trackers or eMule, the threat is that they are even more trust-based than the rest of the Internet. You can never know what you download until you get it. So you’d better be using trustworthy resources. Also, it is reasonable to scan the folder containing the downloaded items with the antivirus as soon as the downloading is finished.
How do I get rid of the Kopytzempereebet virus?
It is important to inform you that besides encrypting your files, the Kopytzempereebet virus will most likely deploy the Azorult Spyware on your computer to get access to credentials to various accounts (including cryptocurrency wallets). That spyware2 can extract your credentials from your browser’s auto-filling cardfile.
Often racketeers would decode several of your files to prove that they indeed have the decryption tool. As Kopytzempereebet virus is a relatively recent ransomware, anti-malware designers have not yet found a way to reverse its work. Nevertheless, the decoding instruments are constantly updated, so the solution may soon be available.
Of course, if the criminals succeed in encoding someone’s essential files, the hopeless person will probably fulfill their demands. Despite that, paying a ransom gives no guarantee that you’re getting your blocked information back. It is still risky. After receiving the ransom, the racketeers may deliver a wrong decryption code to the victim. There were reports about ransomware developers simply disappearing after getting the ransom without even writing back.
The best safety measure against ransomware is to have aan OS restore point or the copies of your critical files in the cloud disk or at least on an external disk. Surely, that might be not enough. Your most crucial thing could be that one you were working upon when it all went down. Nevertheless, it is something. It is also reasonable to scan your drives with the antivirus program after the OS is rolled back.
Kopytzempereebet is not the only ransomware of its kind, since there are other specimens of ransomware out there that act in the same manner. For instance, Ccew, Qqmt, Vveo, and some others. The two basic differences between them and the Kopytzempereebet are the ransom amount and the method of encryption. The rest is almost identical: files become encrypted, their extensions changed, ransom notes emerge in each folder containing encoded files.
Some fortunate people were able to decrypt the blocked files with the help of the free tools provided by anti-ransomware developers. Sometimes the hackers accidentally send the decoding key to the victims in the ransom readme. Such an epic fail allows the user to restore the files. But of course, one should never expect such a chance. Remember, ransomware is a bandits’ technology to lay their hands on the money of their victims.
How сan I avert ransomware infection?
Kopytzempereebet ransomware has no endless power, so as any similar malware.
You can protect yourself from its attack in several easy steps:
- Ignore any letters from unknown senders with strange addresses, or with content that has likely no connection to something you are waiting for (how can you win in a money prize draw without participating in it?). In case the email subject is more or less something you are waiting for, scrutinize all elements of the questionable email carefully. A fake email will surely contain a mistake.
- Avoid using cracked or unknown software. Trojan viruses are often spreaded as an element of cracked software, most likely as a “patch” preventing the license check. Understandably, untrusted programs are very hard to tell from trustworthy software, as trojans sometimes have the functionality you seek. Try searching for information on this software product on the anti-malware forums, but the optimal solution is not to use such programs at all.
- And finally, to be sure about the safety of the objects you downloaded, use GridinSoft Anti-Malware. This software will be a perfect defense for your PC.

Frequently Asked Questions
🤔 How can I open “.KOPYTZEMPEREEBET” files?Can I somehow access “.KOPYTZEMPEREEBET” files?
Negative. That is why ransomware is so frustrating. Until you decode the “.KOPYTZEMPEREEBET” files you will not be able to access them.
🤔 I really need to decrypt those “.KOPYTZEMPEREEBET” files ASAP. How can I do that?
If the “.KOPYTZEMPEREEBET” files contain some really important information, then you probably have them backed up. Otherwise, you might try to employ System Restore. The only question is whether you have saved any Restore Points that would be helpful now. The rest of the methods require patience.
🤔 You have advised using GridinSoft Anti-Malware to get rid of the Kopytzempereebet virus. Does it mean that all my files, currently encrypted, will be removed too?
Of course not. Unlike the ransomware program itself, the encrypted files do not jeopardize your system.
GridinSoft Anti-Malware only deals with actual threats. The malware that has infected your PC is most likely still active and it scans your system periodically to arrest any new files you might create on your computer after the initial attack. As it has been said above, the Kopytzempereebet virus comes with the company. It installs backdoors and keyloggers that can steal your account credentials and provide malefactors with easy access to your PC in the future.
🤔 What actions should I take if the Kopytzempereebet virus has blocked my computer and I can’t get the activation code.
If that happened, you need to have a flash memory card with a pre-installed Trojan Killer. Use Safe Mode to perform the cleaning. You see, the ransomware runs automatically as the system launches and encodes any new files created or brought into your machine. To block this function – use Safe Mode, which allows only the vital applications to run automatically. Consider reading our manual on running Windows in Safe Mode.
