What is Foqe file extension
.Foqe file extension is an extension that is used by a new variant of STOP ransomware. The ‘Foqe’ variant is very similar in its characteristics to other variants of this ransomware. It also encrypts files, and then renames them, giving them a new filename consisting of their old and ‘.foqe’ appended at the end. Criminals demand a ransom for a key-decryptor pair, which is necessary to unlock encrypted data. Fortunately, there is a free decryptor. It allows everyone to decrypt files that have been affected with any version of STOP (Djvu) ransomware, including ‘Foqe’ variant. Scroll down to find out more about the decryptor, where to download it and how to use it to decrypt .foqe files.
What is Foqe ransomware
Foqe ransomware is the 256th version of STOP (Djvu) ransomware. The behavior of this variant and the methods of its distribution are similar to other variants of STOP (Djvu). As before, the cybercriminals use adware, crack, activators and torrents web-sites to spread this ransomware. Upon execution, Foqe virus encrypts all files on the victim’s computer. This means that files on all drives connected to the computer will be encrypted. Files located on external devices, such as files on a flash drive and cloud storage, can also be encrypted.
Each file is encrypted using a strong encryption algorithm and a long key. The key that the virus uses can be of two types: online key and offline key. The security researchers found that if Foqe virus could establish a connection to its command-and-control (C&C) server before encrypting the files, then the key obtained from it is used, this key is called ‘online key’. Such a key is unique for each infection, which means that the key for decrypting files from one victim is not suitable for decrypting files from another victim. If Foqe could not establish a connection with the C&C server, then it uses an encryption key, which is the same for all cases of infection. This type of key is called ‘offline key’.
The authors of Foqe virus created it so that it encrypts as many files as possible. Therefore, the virus does not encrypt the entire file, but only its initial part, in the amount of 154kb. Thanks to this, the contents of some types of files (for example, zip archives) can be restored by simply returning the old filename to them, that is, removing the extension ‘.foqe’. In the process of encryption, the virus skips files, that is, leaves them in their original state if:
- files are located in the Windows system directories
- files have the extension .bat, .sys, .dll, .lnk, .ini
- files are named ‘_readme.txt’
All other files will be encrypted. That is, the contents of the following common file types can be encrypted:
.db0, .docm, .wb2, .dazip, .yal, .xxx, .mdbackup, .sid, .sidn, .indd, .x, .xf, .css, .kdb, .bsa, .pkpass, .dba, .apk, .cfr, .py, .2bp, .wps, .mef, .layout, .kdc, .zip, .ncf, .raf, .upk, .3fr, .docx, .t12, .qic, .rwl, .dbf, .wpb, .wp, .cdr, .wav, .xdl, .vfs0, .bay, .jpeg, .odc, .hkx, .wsd, .wpl, .svg, .zw, .xlsm, .7z, .wbz, .t13, .wma, .odm, .cas, .rgss3a, .ltx, .wgz, .bc7, .doc, .pfx, .hvpl, .wmf, .bik, .cr2, .wpe, .orf, .wn, .map, .litemod, .der, .wbd, .rar, .dxg, .sb, .p7c, .xlsx, wallet, .r3d, .ntl, .ibank, .mpqge, .menu, .wbc, .eps, .lbf, .xar, .arw, .vtf, .epk, .vdf, .cer, .wri, .crw, .x3f, .wps, .xll, .wmv, .avi, .iwi, .wpt, .dwg, .mcmeta, .dcr, .srw, .ws, .ptx, .dmp, .re4, .pdf, .xmind, .lvl, .erf, .wp6, .zif, .z3d, .odb, .fos, .das, .xwp, .sql, .sidd, .z, .1, .webdoc, .wm, .wpd, .wbk, .hplg, .mdf, .xls, .js, .fpk, .wp4, .pptm, .wdp, .sis, .xbplate, .sav, .wp7, .xml, .pak, .mddata, .tax, .xy3, .sie, .mdb, .pef, .arch00, .ztmp, .1st, .bkf, .0, .icxs, .wmv, .rb, .jpg, .mp4, .wma, .ysp, .xbdoc, .txt, .bc6, .blob, .wp5, .bkp, .xyw, .rw2, .wmo, .xlk, .gdb, .dng, .png, .xlsb, .rofl, .mrwref, .wot, .zi, .wmd, .x3f, .slm, .asset, .wotreplay, .srf, .xls, .xx, .webp, .mov, .xyp, .xpm, .3ds, .vpk, .p7b, .p12, .hkdb, .gho, .xdb, .qdf, .sr2, .pdd, .d3dbsp, .lrf, .wpa
After Foqe virus encrypts the file, it renames this file. Thus, each encrypted file gets a new filename. For example, the file ‘image.jpg’, after it is encrypted, will be renamed to ‘image.jpg.foqe’. In all directories where there is at least one encrypted file, the virus drops a file with the name ‘_readme.txt’. A sample of the contents of this file is shown in the figure below.
Criminals use this file to demand ransom from victims of Foqe virus. The message said that the victim’s files were encrypted with a strong algorithm and a key. The authors of the virus demand a ransom in exchange for a key and a decryptor. The ransom is $490 and must be paid within 72 hours. If the victim does not pay it during this time, the ransom increases to $980. Attackers offer to decrypt one file for free, but this file should be small in size and not contain any important information. Of course, decryption of one file cannot guarantee that after paying the ransom the victim will be able to recover files affected with the virus.

|Foqe File Decrypt Tool
Security researchers confirm that Foqe virus does indeed encrypt files, and also that a decryptor and a key are required to decrypt them. Fortunately for all victims of this virus, as well as other variants of STOP (Djvu) ransomware, EmsiSoft developed a free decryptor. Thus, it is possible to decrypt .foqe files. This decryptor has only one limitation, so far it can decrypt files that were encrypted with an offline key. If the victim’s files were encrypted with an online key, then they cannot be decrypted. But even in this case, not everything is lost. Each Foqe victim has a chance to restore some or all of the encrypted files to their original state using alternative methods, which are described below.
How to remove Foqe ransomware virus; Recover, Decrypt .foqe files
If your files were encrypted with .foqe extension, then we recommend using the following steps. These steps will help you remove the ransomware and decrypt (restore) the encrypted files. Read the entire manual carefully. To make it easier for you to follow the instructions, we recommend that you print it or open it on your smartphone.

How to remove Foqe ransomware virus
You need to remove the Foqe ransomware virus and its autostart entries before proceeding to decrypt or restore encrypted files. This must be done since otherwise the ransomware may re-encrypt the restored files. You can stop the ransomware from working, as it is not difficult to do. Another option is to perform a full system scan using free malware removal tools capable of detecting and removing ransomware infection.
It is very important to scan the computer for malware, as security researchers found that spyware could be installed on the infected computer along with the Foqe ransomware. Spyware is a very dangerous security threat as it is designed to steal the user’s personal information such as passwords, logins, contact details, etc. If you have any difficulty removing the Foqe virus, then let us know in the comments, we will try to help you.
To remove Foqe ransomware, follow the steps below:
- Kill the Foqe ransomware process
- Disable the Foqe ransomware Start-Up
- Delete the Foqe ransomware Task
- Delete the Foqe ransomware File
- Scan computer for malware
Kill the Foqe ransomware process
Press CTRL, ALT, DEL keys together.
Click Task Manager. Select the “Processes” tab, look for something suspicious that is the Foqe ransomware then right-click it and select “End Task” or “End Process” option. If your Task Manager does not open or the Windows reports “Task manager has been disabled by your administrator”, then follow the guide: How to Fix Task manager has been disabled by your administrator.
It is not difficult to detect a process related to the Foqe ransomware. When looking for a malicious process, pay attention to the process icon and its name. Most often, this ransomware has a process name in the following format: 4-characters.tmp.exe or 4-characters.exe. For example: 7533.tmp.exe, A4b1.exe, CD15.tmp.exe, 19b2.exe. If you do not find a process with a similar name in the list of processes, then most likely the Foqe ransomware has finished working. But keep in mind, if you do not remove the ransomware autostart entries, as demonstrated below, and do not delete its file, then after a while it may start again, and if it finds unencrypted files, immediately encrypt them.
Disable the Foqe ransomware Start-Up
Select the “Start-Up” tab, look for something similar to the one shown in the example below, right click to it and select Disable.
Close Task Manager.
Delete the Foqe ransomware Task

How to decrypt .foqe files
Files with the extension ‘.foqe’ are encrypted files. In other words, the contents of these files are locked. Their contents cannot be read even if you rename files or change their extension. As we reported above, there is a free decryptor, which was created by Emsisoft. This decryptor allows everyone to decrypt .foqe files.
To decrypt .foqe files, use Foqe File Decrypt Tool
- Download Foqe 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.
Foqe File Decrypt Tool is a free software that is able to decrypt files encrypted with an offline key. Files encrypted with an online key cannot yet be decrypted. The online key is unique to each infected computer, and at the moment there is no way to obtain this key. Of course, the authors of Foqe virus own this key, but we do not think that paying a ransom is the right way to decrypt .foqe files. In the case when the files are encrypted with an online key, there is a chance to restore the encrypted files using alternative methods, which are described below.
How to find out which key was used to encrypt files
Since Foqe File Decrypt Tool only decrypts files encrypted with the offline key, each Foqe’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 ‘0233’ – 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’, Foqe ransomware 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.
Foqe File Decrypt Tool : “No key for New Variant online ID”
If, when you try to decrypt .foqe files, Foqe File Decrypt Tool reports:
No key for New Variant online ID: *
Notice: this ID appears to be an online ID, decryption is impossible
It means that your files are encrypted with an ‘online key’ and their decryption is impossible, since only the Foqe 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.
Foqe File Decrypt Tool : “No key for New Variant offline ID”
If, during decryption of .foqe files, Foqe File Decrypt Tool reports:
No key for New Variant offline ID: *t1
Notice: this ID appears be an offline ID, decryption MAY be possible in the future.
It means the following: your files are encrypted with an ‘offline key’, but the key itself has not yet been obtained 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.
If for some reason you were unable to decrypt the encrypted files, then We recommend to follow the news on our Facebook or YouTube channels. So you ‘ll know right away that it ‘s possible to decrypt .foqe files.
This video step-by-step guide will demonstrate How to use STOP Djvu decryptor to decrypt encrypted files.
How to restore .foqe files
If all your files are encrypted with an online key, or the Foqe File Decrypt Tool cannot decrypt the encrypted files, then you only have one thing left, use alternative methods to restore the contents of the encrypted files. There are several alternative methods that may allow you to restore the contents of encrypted files. However, if you have not tried the free decryptor, then try it first by following step 2 of this instruction, and then return here.
Alternative methods of file recovery do not use decryption, so there is no need for a key and decryptor. Before you begin, you must be 100% sure that the computer does not have active ransomware. Therefore, if you have not yet checked your computer for ransomware, do it right now, use free malware removal tools or return to step 1 above.
Restore .foqe files with ShadowExplorer
A free tool named ShadowExplorer is a simple solution to use the ‘Previous Versions’ feature of MS Windows 10 (8, 7 , Vista). You can recover your documents, photos, and music encrypted by Foqe ransomware from Shadow Copies for free. Unfortunately, this method does not always work due to the fact that the ransomware almost always deletes all Shadow copies.
