Cyber threat analysts discovered a new variant of the GandCrab ransomware which named GandCrab V3. Like the previous version of this ransomware, it appends .CRAB extension to encrypted file names. This post will provide you a brief summary of information related to this new ransomware, how to remove GandCrab V3 and how to restore all encrypted photos, documents and music for free.
The GandCrab V3 is a malware which created in order to encrypt files. It hijack a whole personal computer or its data and demand a ransom in order to unlock (decrypt) them. The creators of the GandCrab V3 virus have a strong financial motive to infect as many personal computers as possible. The files that will be encrypted include the following file extensions:
.qic, .wav, .csv, .m4a, .doc, .big, .sr2, .wire, .slm, .cas, .lvl, .bay, .psk, .fsh, .rofl, .ai, .css, .sis, .wp7, .eps, .menu, .mdbackup, .xbplate, .dba, .js, .xlsm, .vfs0, .ntl, .litemod, .xmind, .crt, .dmp, .lbf, .p12, .odt, .zip, .syncdb, .tax, .mdf, .xls, .xy3, .wpt, .wpd, .indd, .wbc, .pptx, .wma, .bsa, .sidd, .yal, .cer, .wma, .p7c, .docx, .wp4, .sav, .wb2, .snx, .hplg, .xpm, .xlgc, .dbf, .pfx, .txt, .0, .rim, .vdf, .ysp, .mrwref, .wsc, .xlsb, .wm, .jpe, .ppt, .ws, .xx, .xml, .wpe, .rtf, .crw, .wbm, .bar, .xlk, .xls, .hkx, .kdc, .xll, .dazip, .wmf, .docm, .zif, .vtf, .wotreplay, .mp4, .sb, .3fr, .w3x, .qdf, .7z, .odc, .x3d, .iwd, .dxg, .odb, .arw, .cdr, .raf, .ptx, .xlsx, .wmv, .der, .pst, .py, .jpeg, .sidn, .p7b, .xar, .map, .wbmp, .xmmap, .srf, .wmv, .blob, .wsd, .x3f, .lrf, .svg, .xyw, .rw2, .webp, .bkp, .icxs, .mef, .xwp, .re4, .erf, .accdb, .rb, .dwg, .nrw, .wdp, .avi, .r3d, .zabw, .pdd, .upk, .1st, .zip, .wmo, .pdf, .wpb, .bc6, .ybk, .epk, .wsh, .forge, .odp, .wpl, .vcf, .desc, .wpg, .sql, .mpqge, .png, .bkf, .y, .zdc, .m3u, .wps, .xyp, .x3f, .pak, .srw, .hvpl, .d3dbsp, .vpp_pc, .xf, .cr2, .ztmp, .wdb, .3dm, .zdb, .fos, .wp6, .pkpass, .dng, .mddata, .z, .esm, .mlx, .sie, .sid, .hkdb, .cfr, .pef, .2bp, .gho, .mdb, .iwi, .xld, .xdb, .wcf, .raw, .x, .asset, .zi, .wri, .yml, .pptm, .wgz, .xlsx, .m2, .3ds, .itdb, .flv, .tor, .xbdoc, .wmd, .wpd, .ods, .itl, .bik, .vpk, .xxx, .wot, .apk, .wbk, .mov, .psd, .ltx, wallet, .gdb, .wps, .ff, .layout, .odm, .xdl, .ibank, .t12, .1, .xlsm, .wpw, .rwl, .kf, .wpa, .sum
Once the encryption procedure is done, it will create a ransom note called “CRAB-DECRYPT.txt” offering decrypt all users files if a payment is made. You can see an one of the variants of the ransomnote below:
---= GANDCRAB V3 =---
All your files documents, photos, databases and other important files
are encrypted and have the extension: .CRAB
The only method of recovering files is to purchase a private key.
It is on our server and only we can recover your files.
The server with your key is in a closed network TOR. You can get
there by the following ways:
0. Download Tor browser - https://www.torproject.org/

2. Open Tor Browser
3. Open link in TOR browser: http://gandcrab2pie73et.onion/[id]
4. Follow the instructions on this page
On our page you will see instructions on payment
and get the opportunity to decrypt 1 file for free.
The ransomnote offers victim to contact GandCrab V3’s developers in order to decrypt all personal files. These persons will require to pay a ransom (usually demand for $300-1000 in Bitcoins). We do not recommend paying a ransom, as there is no guarantee that you will be able to decrypt your documents, photos and music. Especially since you have a chance to restore your documents, photos and music for free using free utilities like ShadowExplorer and PhotoRec.
Unfortunately, at this time, victims of the GandCrab V3 virus cannot decrypt encrypted personal files without the actual encryption key. But you can follow our tutorial below to search for and get rid of GandCrab V3 ransomware virus from your machine as well as restore encrypted photos, documents and music for free.

How to decrypt encrypted files
Currently there is no available method to decrypt CRAB files, but you have a chance to restore encrypted documents, photos and music for free. The virus repeatedly tells the victim that uses a hybrid AES + RSA encryption mode. What does it mean to decrypt the files is impossible without the private key. Use a “brute forcing” is also not a method because of the big length of the key. Therefore, unfortunately, the only payment to the developers of the GandCrab V3 ransomware entire amount requested – the only method to try to get the decryption key and decrypt all your files.
There is absolutely no guarantee that after pay a ransom to the creators of the GandCrab V3 virus, they will provide the necessary key to decrypt your files. In addition, you must understand that paying money to the cyber criminals, you are encouraging them to create a new ransomware.
