What Is STOP/DJVU Ransomware?
STOP/DJVU is the name of a virus that encrypts your files while appending an extension of the same name to each file. Files are locked with both AES and RSA 1024-bit military-grade encryption algorithms. The cryptovirus will encrypt your data and when finished, it will demand money as a ransom to allegedly get your files restored. Keep on reading through the article to see how you could try to potentially recover some of your files.
STOP Ransomware – Decrypter
There is a decrypter tool released for DJVU which requires .NET Framework 4.5.2 installed or a later version. The tool was initially released for the .puma, .pumax, .pumas versions of the cryptovirus. Michael Gillespie reguralrly updates it to support newly discovered verions like .format, .access, .ndarod, .bopador, .novasof, .dodoc, .todar and other. Keep in mind that the tool requires a pair of an original file and its encrypted version.
The decrypter is able to decrypt 148 variants of the ransom-demanding software 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

STOP/DJVU Ransomware – Ways of Distribution
The STOP/DJVU threat might spread its infection in various ways. A payload dropper which initiates the malicious script is being spread around the World Wide Web, and researchers have gotten their hands on a malware sample. If that file lands on your computer system and you somehow execute it – your computer system will become infected. Here is a list of some malicious files known to be used for the activation of this malicious software:
The virus might also distribute its payload file on social media and file-sharing services. Freeware that is found on the Web can be presented as helpful also be hiding the malicious script for the cryptovirus. Refrain from opening files right after you have downloaded them. You should first scan them with a security tool, while also checking their size and signatures for anything that seems out of the ordinary. You should read the tips for preventing ransomware found in the forum section.
In-Depth Overview of the Ransomware
Your files will get encrypted and the malicious code will display a window with instructions on your computer screen. The extortionists want you to pay a ransom for the alleged restoration of your files.
The malware could make entries in the Windows Registry to achieve persistence and could launch or repress processes in a Windows environment. Such entries are typically designed in a way to launch the virus automatically with each start of the Windows operating system.
After encryption the cryptovirus will place a ransom note message inside a file called “!!!YourDataRestore!!!.txt”. You can see its contents from the following screenshot given down here:
The ransom note states the following:
All your important files were encrypted on this PC.
All files with .STOP extension are encrypted.
Encryption was produced using unique private key RSA-1024 generated for this computer.
To decrypt your files, you need to obtain private key + decrypt software.
To retrieve the private key and decrypt software, you need to contact us by email firstname.lastname@example.org send us an email your !!!YourDataRestore!!!.txt file and wait for further instructions.
For you to be sure, that we can decrypt your files – you can send us a 1-3 any not very big encrypted files and we will send you back it in a original form FREE.
Price for decryption $600 if you contact us first 72 hours.
Your personal id:[Redacted]
E-mail address to contact us:
Reserve email address to contact us:
The following e-mail address is used to contact the cybercriminals:
The note states that your files are encrypted with further instructions. You are demanded to pay 600 US dollars in 3 days’ time, otherwise, the price will change. However, you should NOT under any circumstances pay any ransom. Your files may not get recovered, and nobody could give you a guarantee for that. Moreover, giving money to cybercriminals will most likely motivate them to create more crypto viruses or commit different criminal acts.
STOP/DJVU Ransomware – Encryption Process
What is known for the encryption process is that every file that gets encrypted will receive the .STOP extension. The encryption algorithms used to lock the files are AES and RSA 1024-bit.
The targeted extensions of files which are sought to get encrypted are currently unknown and if a list is discovered, it will be posted here as the article gets updated. The files used most by users and which are probably encrypted are from the following categories:
- Audio files
- Video files
- Document files
- Image files
- Backup files
- Banking credentials, etc
The cryptovirus could be set to erase all the Shadow Volume Copies from the Windows operating system with the help of the following command:
→vssadmin.exe delete shadows /all /Quiet
In case the above-stated command is executed that will make the encryption process more efficient. That is due to the fact that the command eliminates one of the prominent ways to restore your data. If your computer device was infected and your files are locked, read on through to find out how you could potentially restore your files back to normal.
