A ransomware called Darus file virus is another development of cybercriminals. The principle of its functioning and the method of distribution is the same as in the case of the Tocue, Gusau, Madek, the only difference is the .darus extension added to the documents, photos and music that are infected with it.
Getting to the user’s PC system, the Darus ransomware virus starts searching for files in all folders and recursively, and after their detection, encrypts each of them using complex ciphered combination that completely blocks them and leads to their dysfunction. This crypto virus is capable of blocking various files such as documents, photos, archives, drawings, video materials, database and web application-related files, as well as its destructive effects can be subjected to backups. Darus file virus encrypts almost of files, including common as:
.odm, .tax, .rtf, .vtf, .docm, .xar, .csv, .wpl, .pptx, .kdb, .mdbackup, .dwg, .p7b, .webp, .xxx, .js, .ysp, .zw, .3dm, .pfx, .wp, .3ds, .jpg, .y, .asset, .rwl, .yml, .gho, .pptm, .dbf, .itdb, .wp7, .sav, .lvl, .0, .pem, .x, .png, .itm, .sidn, .2bp, .fpk, .x3d, .ybk, .wav, .wpb, .py, .ltx, .pkpass, .wri, .odb, .avi, .vpk, .srf, .big, .layout, .1, .hvpl, .xlsx, .ptx, .x3f, .orf, .nrw, .wsh, .sr2, .bay, .wbc, .xlsm, .crt, .cfr, .sid, .mdb, .wgz, .p12, .wdp, .qic, .wbmp, .odt, .wps, .raf, .wdb, .rw2, .wm, .wsc, .ods, .yal, .xyp, .wma, .mrwref, .7z, .pdd, .odc, .kdc, .accdb, .t13, .wpe, .eps, .pst, .wpt, .zif, .bkf, .kf, .snx, .gdb, .wsd, .iwd, .raw, .xmmap, .rofl, .fsh, .sb, .jpe, .wot, .ff, .fos, .ibank, .dba, .svg, .wmf, .ai, .bik, .xwp, .mp4, .pef, .wpd, .rim, .dcr, .apk, .qdf, .xx, .mlx, .dxg, .hkdb, .dmp, .xlk, .x3f, .odp, .wps, .xmind, .litemod, .sum, .xf, .xls, .forge, .wpa, .desc, .css, .wmo, .xll, .vcf, .xld, .zdc, .xls, .wp4, .vfs0, .mpqge, .sidd, .wmv, .slm, .arw, .wbm, .psk, .r3d, .xbplate, .wcf, .cas, .xpm, .bc7, .t12, .hkx, .xdl, .wpg, .cr2, .cdr, .sie, .wb2, .wmv, .rgss3a, .zip, .xlgc, wallet, .bar, .cer, .xml, .zdb, .psd, .z3d, .1st, .map, .ws, .d3dbsp, .rb, .vdf, .doc, .pdf, .wpw, .dazip, .lrf, .wire, .txt, .xlsx, .bsa, .iwi, .flv, .ppt, .mcmeta, .upk, .wpd, .rar, .zi, .esm, .bkp, .wmd, .wbd, .jpeg, .icxs, .blob, .indd, .wma, .sis, .epk, .srw, .xlsm, .wp6, .docx, .z, .der, .xbdoc, .zip, .pak, .itl, .zabw, .xyw, .webdoc, .m4a, .sql, .wp5, .syncdb, .hplg, .dng
All locked files become useless and get the .darus extension and each directory containing the encrypted files contains a ransom instructions informing the user about the presence of ransomware virus in the computer and its destructive impact on the target files. The cyber criminals inform each user that he has the ability to recover encrypted files only paying a ransom. After transferring the specified amount to cyber criminals, the victim will receive a private key from them, which will allow to decrypt files affected by the Darus ransomware virus. If the money for the purchase of a key for decrypting files will be transferred to the cyber criminals within 72 hours, they are ready to give the victim a discount of 50%.

How to decrypt .darus files
To date, there is no other method to restore the encrypted files, but only to pay the money to cybercriminals. Developers of free Darus decryption utilities which can unlock these files are working on creating them, but the result is not yet, and it is not known when it will be.
Never pay the ransom! However, the victim who will pay the money to developers of the Darus crypto malware cannot be completely sure of obtaining a special code key, because he is dealing with unscrupulous and dishonest people who are ready to commit any immoral actions, including hiding after receiving the money from the victim, and not providing a decryption tool (key) to decrypt encrypted photos, documents and music.
Of course, it can not be considered that the only correct method out of the situation when your machine is affected with Darus ransomware, will be the payment of ransom, as this only leads to the prosperity of illegal actions of fraudsters. The smart thing to do is to try to recover the locked files from the backup or wait for the release of the Darus decryption tool to decrypt them. You can also try to unlock photos, documents and music using free programs listed below.
Darus decryption tool
With some variants of Darus ransomware, it is possible to decrypt encrypted files using free tools listed below.
Michael Gillespie (@) released the Tocue decryption tool named STOPDecrypter. It can decrypt .Darus files if they were locked by one of the known OFFLINE KEY’s retrieved by Michael Gillespie. Please check the twitter post for more info.
STOPDecrypter is a program that can be used for Darus files decryption. One of the biggest advantages of using STOPDecrypter is that is free and easy to use. Also, it constantly keeps updating its ‘OFFLINE KEYs’ DB. Let’s see how to install STOPDecrypter and decrypt .Darus files using this free tool.
- Installing the STOPDecrypter is simple. First you will need to download STOPDecrypter on your Windows Desktop from the following link.
- After the downloading process is done, close all applications and windows on your machine. Open a file location. Right-click on the icon that’s named STOPDecrypter.zip.
- Further, select ‘Extract all’ and follow the prompts.
- Once the extraction process is finished, run STOPDecrypter. Select Directory and press Decrypt button.
If STOPDecrypter does not help you to decrypt .Darus files, in some cases, you have a chance to restore your files, which were encrypted by ransomware. This is possible due to the use of the tools named ShadowExplorer and PhotoRec. An example of recovering encrypted files is given here.
