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.
