This article will answer the questions “What Is STOP Ransomware Decryptor?”, “What Is Encryption?” and “How to Use STOP Ransomware Decryptor?”.
What Is Encryption?
The process of changing information or data of an object, like a password or a file, is known as encryption. Encryption is commonly used to make information exchange secure, such as email or chat. In cybersecurity, encryption is closely associated with file encrypting viruses, also referred to as ransomware crypto-viruses, like in the case of STOP Ransomware. These malicious software infect a computer and use encryption on vital files to demand money in exchange for unlocking them, usually in BitCoin. Note that encryption is achieved by using an encryption algorithm.
What Are Encrypted Files?
An encrypted file is a file that has been encoded using an encryption algorithm and a secret key, so that it can only be decoded using the same secret key. It is used to protect the contents of the file against unauthorized access or modification. Encrypted files are commonly used for secure data storage and transmission.
How to Use STOP Ransomware Decryptor
STOP ransomware is the type of malware, with the main idea behind it, to get users to pay a ransom in BitCoin to get their files back.
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:
Step 1) Right-click on the decrypter and click on Run as Administrator as shown below:
Step 2) Agree with the license terms:
Step 3) Click on “Add Folder” and then add the folders where you want files decrypted as shown underneath:
Step 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.
Emsisoft malware researchers have released a new decryption tool, which is able to decrypt ONLINE and OFFLINE keys for 148 variants of the STOP/DJVU ransomware out of 202+ available. The following extensions are supported by the decryption tool:
→ .gero, .hese, .seto, .peta, .moka, .meds, .kvag, .domn, .karl, .nesa, .noos, .kuub, .reco, .bora, .nols, .werd, .coot, .derp, .meka, .mosk, .peet, .mbed, .kodg, .zobm, .msop, .hets, .mkos, .nbes, .reha, .topi, .repp, .alka, .shadow, .djvu, .djvur, .djvuu, .udjvu, .uudjvu, .djvuq, .djvus, .djvur, .djvut, .pdff, .tro, .tfude, .tfudet, .tfudeq, .rumba, .adobe, .adobee, .blower, .promos, .promoz, .promorad, .promock, .promok, .promorad2, .kroput, .kroput1, .pulsar1, .kropun1, .charck, .klope, .kropun, .charcl, .doples, .luces, .luceq, .chech, .proden, .drume, .tronas, .trosak, .grovas, .grovat, .roland, .refols, .raldug, .etols, .guvara, .browec, .norvas, .moresa, .vorasto, .hrosas, .kiratos, .todarius, .hofos, .roldat, .dutan, .sarut, .fedasot, .berost, .forasom, .fordan, .codnat, .codnat1, .bufas, .dotmap, .radman, .ferosas, .rectot, .skymap, .mogera, .rezuc, .stone, .redmat, .lanset, .davda, .poret, .pidom, .pidon, .heroset, .boston, .muslat, .gerosan, .vesad, .horon, .neras, .truke, .dalle, .lotep, .nusar, .litar, .besub, .cezor, .lokas, .godes, .budak, .vusad, .herad, .berosuce, .gehad, .gusau, .madek, .darus, .tocue, .lapoi, .todar, .dodoc, .bopador, .novasof, .ntuseg, .ndarod, .access, .format, .nelasod, .mogranos, .cosakos, .nvetud, .lotej, .kovasoh, .prandel, .zatrov, .masok, .brusaf, .londec, .krusop, .mtogas, .nasoh, .nacro, .pedro, .nuksus, .vesrato, .masodas, .cetori, .stare, .carote, .gero, .hese, .seto, .peta, .moka, .kvag, .karl, .nesa, .noos, .kuub, .reco, .bora
If your variant is featured above, it should be 100% decryptable now.
STOP Ransomware – More Information
As reported by Michael Gillespie, the operators of STOP ransomware have altered its code in newer versions. These changes make the way the decrypter work impossible, starting with .coharos, .gero, and .hese. Apparently, the cybercriminals started to utilize proper asymmetrical encryption, meaning the offline keys will no longer be valid for decryption after the release of the final keys Gillespie extracted.
The researcher is now working towards closing this decrypter, and continuing work on a new decrypter that will work only for the old versions of STOP (up to .carote). The new decrypter will completely replace STOPDecrypter once it’s released, and will work in a different way, the researcher said.
This version of STOPDecrypter currently works for .nuksus, .cetori, .carote, and .stare files. It is designed to support specific offline IDs, so it may not be effective for all occasions of the various iterations of the ransomware.
Researchers have categorised STOP ransomware to be of several different variants.
- The variant with the uppercase extensions.
- The Puma variants of STOP.
- The Djvu STOP variants.
The uppercase file extension variants only include uppercase extensions and they are a bit outdated, while the Puma and Djvu variants are relatively new ones as the Djvu variants of STOP ransomware being the latest viruses to hit the world.
How to Decrypt Your Files Using older STOP Ransomware decryptor version (Advised Against)
To decrypt your files with the older STOPDecrypter, you can follow these old instructions, but researchers advise that you use the newer version provided above. Unfortunately since the decryption tool of STOP Ransomware has been discontinued, it is recommended that you try out the Emsisoft Decryption Steps written above
Step 1) Extract the decrypter somewhere:
Step 2) Run it as an administrator:
Step 3) Click on “Select Directory” and then select a folder, where your important files are encrypted.
Step 4) Click on Decrypt and be patient. The software will return how many files were decrypted:
Remove STOP Ransomware
Be sure to only remove STOP once your files are decrypted. If the files are not decrypted, you should wait until security researchers update the decryptor to work for your variant. Until then, we strongly recommend that you backup your encrypted files and NOT pay the ransomware. Also, you can try and get some of your files back by following the alternative recovery instructions underneath. They are no guarantee that you will get all your files back, but with their help, you could restore at least some of the files.
To remove STOP ransomware, you should follow the first two steps. If they do not work, then try to remove this virus automatically with an advanced anti-malware software. Such software is often the preffered removal method, since it aims to detect an delete all STOP files plus remove them.

Step 2: Uninstall STOP Ransomware 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 STOP Ransomware 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 STOP Ransomware 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 STOP Ransomware
Step 5: Try to Restore Files Encrypted by STOP Ransomware.

Hola compañero tengo el mismo problema, pudiste solucionarlo?
This is another garbage that says a world of things but doesn’t solve anything in the matter of decrypting files with the final extension after the infected file extension Example. script.json
Then it looks like this when infected— Script.json.qqjj
Everything on the computer is left with this at the end qqjj and it is not possible to open anything, txt, photos, videos, games everything it leaves everything unusable.
This article is a very detailed, informative guide about all the iterations of STOP/DJVU ransomware, including the decryptable versions and information about the decrypter itself. The article doesn’t mislead in any way and actually says what versions can be decrypted.
Hello. I’ve been attacked 2 days ago and unfortunately it succeeded. The encryption of my files is (i think online) and changed file extensions to .mppn. Is there any way to get my data back… Even part of it. Thanks anyway
