What is Jope file extension
.Jope file extension is a filename extension that is appended to the name of files affected by the latest version of STOP (djvu) ransomware. Ransomware is a malware that encrypts victims’ files and thus locks up the information contained in them. Ransomware developers demand a ransom in exchange for a decryptor and a key, which are necessary for decrypting the files. Fortunately there is a free decryptor. Jope File Decrypt Tool is a program that in some cases can help decrypt encrypted files. In addition to this program, there are several other ways to restore the contents of encrypted files.
What is Jope ransomware
Jope ransomware is new malware that is the 218th variant of STOP (DJVU) ransomware. Like other versions of this ransomware, it is distributed through key generators, cracked software, adware and torrents web-sites. Upon execution, Jope creates a folder in the Windows system directory and copies itself there. Then the virus changes some Windows OS settings so that it starts automatically every time the PC is turned on or restarted.
Jope ransomware collects information about the victim’s computer, after which it tries to establish a connection with its command-and-control server (C&C). If the connection has been established, the virus receives a key (so called ‘online key’) from the command server that will be used to encrypt files. In addition, Jope virus may receive additional commands and files that will be executed on the victim’s computer. If Jope ransomware could not connect to the command server, then it uses a fixed key, which the security researchers called ‘offline key’.
There is a significant difference between ‘online key’ and ‘offline key’. The online key is unique for each victim, that is, the key from one victim will not help decrypt the files of the other victim. The offline key is the same for all victims. Thus, it can be used to decrypt files regardless of where they were encrypted.
Having a key to encrypt files, Jope virus proceeds directly to the process of encrypting files. It encrypts file-by-file, so that all files of the victim will be encrypted. It doesn’t matter where the files are located, on the internal drive, flash drive, external media, cloud storage, all of them can be encrypted. There is a small exception, the virus does not encrypt files located in the Windows system directories, files with the extension from the list ‘.lnk, .bat, ini, .sys, .dll’ and files with the name ‘_readme.txt’. Thus, almost all of the victim’s data will be encrypted, including documents, pictures, databases, archives and other types of files, such as:
.fos, .dwg, .xll, .xls, .mcmeta, .wn, .ws, .epk, .z, .d3dbsp, .ptx, .vcf, .x3d, .dba, .sid, .sidd, .xlsm, .slm, .js, .wri, .vdf, .1st, .wpb, .x3f, .wpl, .wpe, .accdb, .p12, .bay, .wmo, .sum, .qic, .jpeg, .wpd, .rw2, .bkf, .vpp_pc, .mpqge, .tax, .hvpl, .mddata, .bik, .lrf, .dmp, .xdb, .wgz, .xld, .vpk, .menu, .dazip, .ppt, .ai, .litemod, .p7b, .sr2, .odt, .wdb, .wp7, .zabw, .xmind, .fsh, .zdc, .wpd, .m4a, .wpg, .wma, .dxg, .bc7, .xdl, .pem, .sis, .jpg, .xxx, .crw, .wb2, .wdp, .css, .esm, .bar, .cdr, .zw, .m2, .xyw, .zdb, .svg, .mrwref, .arw, .wmd, .nrw, .xpm, .ztmp, .big, .mlx, .7z, .xbplate, .zip, .wmf, .mov, .raf, .iwd, .sie, .bkp, .mp4, .0, .docx, .ltx, .syncdb, .psd, .vfs0, .xls, .wot, .x3f, .forge, .rwl, .ysp, .pst, wallet, .doc, .wps, .py, .vtf, .wbmp, .itdb, .mef, .x, .xyp, .ibank, .sidn, .xf, .3dm, .y, .pak, .wbz, .wsc, .xy3, .wpw, .pptx, .tor, .yal, .txt, .asset, .indd, .xlsx, .t12, .ntl, .kdc, .w3x, .bsa, .xml, .icxs, .pdd, .xlk, .xlsb, .m3u, .wotreplay, .odb, .ybk, .db0, .sav, .rofl, .xx, .png, .blob, .wmv, .orf, .pef, .wps, .kdb, .ff, .wmv, .sql, .wp4, .wma, .xlsx, .dcr, .odm, .rar, .ncf, .wav, .xmmap, .apk, .layout, .psk, .crt, .hkx, .srf, .arch00, .erf, .p7c, .mdbackup, .wp6, .gho, .wbd, .sb, .wire, .z3d
Each file that has been encrypted by Jope virus will be renamed. It will append the extension ‘.jope’ at the end of the name of the affected file. Thus, a file named ‘image.jpg’, after it is encrypted, will receive the name ‘image.jpg.jope’. To encrypt as many files as possible in the minimum time, the virus does not encrypt the entire file, but only its initial part in the amount of 154 kb. Jope virus encrypts files sequentially, when all files in the directory are encrypted, it places a new file in it. This file is called ‘_readme.txt’ and its contents are shown below.
This file is a ransom note that is a message from Jope creators. In this message, the criminals report that the victim’s files are encrypted and there is only one way to decrypt them – buy the key and the decryptor from them. Attackers set the price for the key and decryptor at $980. If the victim pays the ransom within 72 hours, then Jope authors agree to make a discount of half the ransom, that is, reduce the size of the ransom to $490. Criminals offer to decrypt one file for free. To do this, the victim needs to send this file to one of the email addresses listed in the ransom demand message. But successful decryption of one file does not guarantee the possibility of decryption of files even after payment of the ransom.

How to decrypt .jope files
To decrypt .jope files, you need to use a unique key and decryptor. Security researchers confirm that it is impossible to access the contents of encrypted files without decryption. Renaming the affected files, changing their extension cannot help the victim, the files will still remain encrypted. Fortunately, there is a free Jope File Decrypt Tool called STOP Djvu decryptor. In some cases, it can help decrypt .jope files.
To decrypt .jope files, use Jope File Decrypt Tool
- Download Jope File Decrypt Tool from the following link.
STOP Djvu decryptor
- Scroll down to ‘New Djvu ransomware’ section.
- Click the download link and save the decrypt_STOPDjvu.exe file to your desktop.
- Run decrypt_STOPDjvu.exe, read the license terms and instructions.
- On the ‘Decryptor’ tab, using the ‘Add a folder’ button, add the directory or disk where the encrypted files are located.
- Click the ‘Decrypt’ button.
As we have said several times, this decryptor can decrypt files only in some cases, when the files were encrypted with an ‘offline key’. If the files were encrypted with an ‘online key’, then they cannot be decrypted. The reason for this is that the decryption key is in the hands of criminals and this key can not be determined. But even in this case, there is a chance to restore the contents of encrypted files, we will talk about this in section “How to restore .jope files” of this article.
How to find out which key was used to encrypt files
Since Jope Decrypt Tool only decrypts files encrypted with the offline key, each Jope’s victim needs to find out which key was used to encrypt the files. Determining the type of key used is not difficult. Below we give two ways. Use any of them.
Find out the type of key using ‘_readme.txt’ file
- Open the ransom demand message (‘_readme.txt’ file).
- Scroll down to the end of the file.
- There you will see a line with the text ‘Your personal ID’.
- Below is a line of characters that starts with ‘0218’ – this is your personal id.
Find out the type of key using ‘PersonalID.txt’ file
- Open disk C.
- Open directory ‘SystemID’.
- Open file named ‘PersonalID.txt’. This file lists ‘Personal ID’s that match the keys that the virus used to encrypt files.
The ‘Personal ID’ is not a key, it is an identifier related to a key that was used to encrypt files. If the ID ends with ‘t1’, then the files are encrypted with an offline key. If the ID does not end with ‘t1’, Jope virus used an online key. If you could not figure out how to determine which key was used to encrypt files, then we can help. Just write a request here or in the comments below.
Jope Decrypt Tool : No key for New Variant offline ID
If during decryption of .jope files the decryptor reports No key for New Variant offline ID, then this means the following: your files are encrypted with an ‘offline key’, but the key itself has not yet been found by security researchers, in this case, you need to be patient and wait a while, in addition, you can also use alternative ways for recovering encrypted data. It is impossible to say exactly when the ‘offline key’ will be determined. Sometimes it takes several days, sometimes more. We recommend that you try to decrypt .jope files from time to time. You can also use alternative ways listed below for recovering encrypted data.
Jope Decrypt Tool : No key for New Variant online ID
If, when you try to decrypt .jope files, the decryptor reports No key for New Variant online ID, then this means that your files are encrypted with an ‘online key’ and their decryption is impossible, since only the Jope authors have the key necessary for decryption. In this case, you need to use alternative methods listed below to restore the contents of encrypted files.
How to restore .jope files
If Jope Decrypt Tool did not help you, or your files are encrypted using an online key, then there is no need to panic! There are several other alternative methods that may allow you to restore the contents of encrypted files. Once again, remember to be sure to scan your computer for ransomware and malware using free malware removal tools. You must be sure that Jope ransomware is completely removed.
Use shadow copies to restore .jope files
First of all, try to recover .jope files from Shadow Volume Copies, which are automatically created by Windows OS. In order to recover photos, documents and music encrypted by Jope ransomware from Shadow Volume Copies you can use a tool called ShadowExplorer. We recommend using this free utility because it is small in size, has a simple interface and does not require installation on a computer. Unfortunately, ransomware often removes all Shadow copies. Therefore, if Shadow Explorer cannot help you, then immediately proceed to the second method, which is given below.
Visit the following page to download the latest version of ShadowExplorer for Windows. Save it on your Desktop.
