Kampret is the name of a ransomware cryptovirus. The extension .lockednikampret will get appended to each encrypted file. AES is believed to be the encryption algorithm which is used, as the ransomware is suggested to be a variant from the HiddenTear/EDA2 project. The Kampret cryptovirus will create a ransom note in a text file. Keep on reading and see how you could try to potentially recover some of your files.

Kampret Ransomware – Infection Spread
Kampret ransomware could spread its infection in multiple ways. A payload file which initiates the malicious script for the ransomware in question is seen before on the Internet. Your computer machine will get encrypted by the cryptovirus if its malicious script gets executed. You can preview one such payload dropper, uploaded to the VirusTotal service by malware researchers, from below here:
Kampret ransomware might also be spreading its payload file on social media sites and file-sharing networks. Freeware that is spread on the Internet can be presented as helpful but could also hide the malicious script for this cryptovirus. Refrain from opening files after you have downloaded them, especially if they are coming from suspicious places like emails or links of unknown origin. Instead, you should scan the files with a security tool and check their size and signatures for anything that seems out of place. Read the Tips for preventing ransomware from the forum section to see how to avoid infection.
Kampret Ransomware – Detailed Description
Kampret ransomware is also a cryptovirus. The etymology of its name is interesting. Kampret is an Indonesian word that literally translates to “bat” but is also used in that language as a curse word. Nonetheless, the ransomware could have a version named “Kampretos” as well. The extension .lockednikampret will get appended to all files that become locked after the encryption process is finished.
The web address https://whereyougoiaminhere.tk/aomh/ associated with the ransomware and is seen in the following image:
Inside that site now are only sitting a couple of document files.
Kampret ransomware could make entries in the Windows Registry to achieve some form of persistence, and even launch and repress processes inside the Windows Operating System. Some of these entries are designed in a way that will start the virus automatically with every launch of Windows.
The ransom note will be placed inside a file after the encryption process is complete. The file with the ransom note is named READ_ME.txt file. Inside it there will be instructions for paying the ransom. Here is how the note may possibly look like:
The note will read something along the lines of the following:
Your files has been encrypted by Krampet
Pay 0.5BTC to my bitcoin address [REDACTED] And send the proof to my email kampretos@protonmail.com
The ransomware is reported to be a HiddenTear variant by the malware researcher Karsten Hahn. You can read more about the HiddenTear/EDA2 open-source project from the corresponding article in the blog.
Inside the note of Kampret ransomware there is the kampretos@protonmail.com e-mail address provided for contacting the cybercriminals. The encrypted e-mail service ProtonMail is used, which makes it near impossible for tracking down the criminals. The ransom sum that is demanded is 0.5 Bitcoin, which currently is equivalent to 607 US dollars. However, you should NOT under any circumstances pay those crooks, neither should you try contacting them. Your files may not get restored, and nobody could guarantee that. Furthermore, giving money to these criminals will likely motivate them to do crime, such as the creation of ransomware viruses.
Kampret Ransomware – Encryption Process
Kampret ransomware is a HiddenTear variant as mentioned before, and therefore it will most probably seek to encrypt files that have the following extensions:
→.txt, .doc, .docx, .xls, .xlsx, .pdf, .pps, .ppt, .pptx, .odt, .gif, .jpg, .png, .db, .csv, .sql, .mdb.sln.php, .asp, .aspx, .html, .xml, .psd, .frm, .myd, .myi, .dbf, .mp3, .mp4, .avi, .mov, .mpg, .rm, .wmv, .m4a, .mpa, .wav, .sav, .gam, .log, .ged, .msg, .myo, .tax, .ynab, .ifx, .ofx, .qfx, .qif, .qdf, .tax2013, .tax2014, .tax2015, .box, .ncf, .nsf, .ntf, .lwp
Every one of the files that gets encrypted will receive the same extension appended to them, and that is the .lockednikampret extension. The encryption which is utilized by the ransomware is believed to be AES as that is the encryption algorithm typically used by HiddenTear variants.
The Kampret cryptovirus might be set to erase the Shadow Copies from the Windows operating system by using the following command:
→vssadmin.exe delete shadows /all /Quiet
If the command above is indeed executed, it will make decryption efforts harder, if you try to use that specific method. Keep on reading and check out what ways you can try to potentially restore some of your files.
Remove Kampret Ransomware and Restore .lockednikampret Files
If your computer got infected with the Kampret ransomware virus, you should have a bit of experience in removing malware. You should get rid of this ransomware as quickly as possible before it can have the chance to spread further and infect other computers. You should remove the ransomware and follow the step-by-step instructions guide provided below.
- Step 1
- Step 2
- Step 3
- Step 4
- Step 5
Step 1: Scan for Kampret with SpyHunter Anti-Malware Tool
Ransomware Automatic Removal - Video Guide
Step 2: Uninstall Kampret and related malware from Windows
Here is a method in few easy steps that should be able to uninstall most programs. No matter if you are using Windows 10, 8, 7, Vista or XP, those steps will get the job done. Dragging the program or its folder to the recycle bin can be a very bad decision. If you do that, bits and pieces of the program are left behind, and that can lead to unstable work of your PC, errors with the file type associations and other unpleasant activities. The proper way to get a program off your computer is to Uninstall it. To do that:
Follow the instructions above and you will successfully delete most unwanted and malicious programs.
Step 3: Clean any registries, created by Kampret on your computer.
The usually targeted registries of Windows machines are the following:
- 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
You can access them by opening the Windows registry editor and deleting any values, created by Kampret there. This can happen by following the steps underneath:
Tip: To find a virus-created value, you can right-click on it and click "Modify" to see which file it is set to run. If this is the virus file location, remove the value.
Before starting "Step 4", please boot back into Normal mode, in case you are currently in Safe Mode.
This will enable you to install and use SpyHunter 5 successfully.
Step 4: Boot Your PC In Safe Mode to isolate and remove Kampret
Step 5: Try to Restore Files Encrypted by Kampret.
Method 1: Use STOP Decrypter by Emsisoft.
Not all variants of this ransomware can be decrypted for free, but we have added the decryptor used by researchers that is often updated with the variants which become eventually decrypted. You can try and decrypt your files using the instructions below, but if they do not work, then unfortunately your variant of the ransomware virus is not decryptable.
Follow the instructions below to use the Emsisoft decrypter and decrypt your files for free. You can download the Emsisoft decryption tool linked here and then follow the steps provided below:
1 Right-click on the decrypter and click on Run as Administrator as shown below:
2. Agree with the license terms:
3. Click on "Add Folder" and then add the folders where you want files decrypted as shown underneath:
4. Click on "Decrypt" and wait for your files to be decoded.
Note: Credit for the decryptor goes to Emsisoft researchers who have made the breakthrough with this virus.
Method 2: Use data recovery software
Ransomware infections and Kampret aim to encrypt your files using an encryption algorithm which may be very difficult to decrypt. This is why we have suggested a data recovery method that may help you go around direct decryption and try to restore your files. Bear in mind that this method may not be 100% effective but may also help you a little or a lot in different situations.
Simply click on the link and on the website menus on the top, choose Data Recovery - Data Recovery Wizard for Windows or Mac (depending on your OS), and then download and run the tool.
