.NEMTY file extension is an extension that is appended to the file that is encrypted with the NEMTY ransomware including its latest version, which is called ‘NEMTY 2.5 REVENGE’. NEMTY virus is a malware that makes the contents of victim files inaccessible by encrypting them. Encrypted files cannot be unlocked by removing the new file extension. The only way to recover .NEMTY files is to decrypt them using the decryptor and a unique key. Fortunately, there is a free decryptor. It allows everyone to decrypt files that are encrypted by most versions of the ransomware. Scroll down to find out more about the decryptor, where to download it and how to use it to decrypt .NEMTY files.
NEMTY virus is really a nasty program. It infects a computer when a victim downloads or runs malware infected files. Criminals lure unwary users into downloading ransomware by hiding malicious code within freeware, cracked versions of paid software, key generators, and so on. Upon execution, an instance of ransomware is installed on victim’s computer.
Once installed on a computer, NEMTY encrypts victim’s files using a strong encryption algorithm and a long key. This key is unique for each infection, which means that the decryption from one victim is not suitable for decrypting files from another victim.
NEMTY tries to encrypt as many files as possible, therefore it encrypts files quickly. Even files located on external drives and cloud storage are not safe. If at the time of file encryption these disks are connected to the computer, then all data on them will also be encrypted. Of course, it does not encrypt Windows system files, as this will cause the computer to stop working. All other files on the victim’s computer will be encrypted. So files of the following types can be encrypted:
.wp5, .sis, .xdl, .docm, .pst, .vcf, .pkpass, .zip, .wpe, .orf, .ws, .2bp, .slm, .dxg, .wp, .svg, .xy3, .jpg, .vfs0, .vpk, .apk, .wdb, .wpd, .erf, .ibank, .asset, .xlsm, .lvl, .ltx, .wpd, .wma, .pptx, .xls, .epk, .wpw, .mlx, .wb2, .zw, .7z, .wmf, .odm, .hkdb, .fsh, .crw, .jpe, .fos, .bik, .vtf, .py, .xxx, .mdb, .wn, .wav, .mef, .xlsx, .js, .wpb, .xlsb, .pfx, .bkf, .wcf, .zdc, .bc6, .xpm, .itdb, .bsa, .t12, .eps, .p12, .cr2, .sql, .srf, .qic, .zip, .gdb, .0, .rtf, .ai, .xls, .cfr, .yal, .mcmeta, .crt, .arw, .wdp, .wsh, .dazip, .sum, .map, .wmv, .yml, .rw2, .jpeg, .p7c, .tax, .layout, .gho, .mp4, .zabw, .iwi, .ppt, .wire, .der, .forge, .ntl, .dwg, .xbplate, .litemod, .dng, .xlgc, .raw, .wpg, .xf, .png, .sav, .tor, .doc, .pdd, .bar, .kf, .sb, .cdr, .p7b, .esm, .snx, .xml, .odb, .zif, .wps, .x3f, .sid, .wbz, .bkp, .wbmp, .pdf, .rim, .icxs, .ncf, .y, .xmmap, .kdc, .xlsm, .sidd, wallet, .w3x, .ybk, .pef, .mdf, .webp, .cer, .db0, .ods, .1, .x3d, .bc7, .desc, .dbf, .bay, .dba, .indd, .odt, .hplg, .das, .fpk, .t13, .wgz, .xyp, .arch00, .odc, .ptx, .wot, .xlk, .wsd, .wmd, .iwd, .kdb, .flv, .wma, .pem, .r3d, .accdb, .itl, .mdbackup, .sidn, .wmo, .wp7, .3dm, .wbm, .mpqge, .pak, .rwl, .lrf
Each file that has been encrypted gets a new filename, which consists of its old filename and the extension ‘.NEMTY-[string of random characters]’ appended to the right. This literally means the following: if the file was called ‘price.xlsx’, then its encrypted version will be called ‘price.xlsx.NEMTY-DK1S8JQ’. NEMTY virus encrypts files in each directory on all drives on the computer. When all the files in the directory are encrypted, it drops a new file with the name ‘NEMTY_[string of random characters]-DECRYPT.txt’ in this directory. The following is the contents of such a file.
This file contains a ransom demand message from NEMTY authors. This ransom note says that all the files on the computer are encrypted and the only working way to decrypt them is to buy a decryptor and a key. Attackers offer the victim to open a page with the address nemty.top/public/pay.php, which contains information on how to decrypt files. Attackers demand a ransom, which must be paid by bitcoins. If the victim does not pay the ransom within 3 months, then the criminals threaten to remove the decryption key from their server and decryption of the victim’s files will be impossible. Criminals offer to decrypt one file for free. Of course, a successful decryption of a single file does not at all guarantee that paying a ransom is a way that will allow the victim to decrypt .NEMTY files.

NEMTY authors tell the truth, saying that the victim’s files are encrypted. Security researchers confirm this, as well as the fact that to decrypt files the victim needs to use the decryptor and the key. Fortunately, a free decryptor was created, which can be used to decrypt files encrypted by most versions of the ransomware. This means that .NEMTY files can be decrypted by this decryptor. If the decryptor does not help decrypt the files, there are several alternative methods, each of which gives a chance to recover encrypted files.
If your files were encrypted with NEMTY virus, we recommend using the following action plan, which will allow you to remove the ransomware and decrypt (restore) the encrypted files. Read carefully the entire instructions below, print it, or open it on your smartphone. This will allow you not to miss anything important.

Decrypt .NEMTY files
Files with extension .NEMTY are encrypted files that cannot be decrypted without a decryptor and a key. NEMTY authors demand a ransom for the key and the decryptor. Of course, no one can guarantee that after paying the ransom, the victim will be able to decrypt the encrypted files. Security experts do not recommend paying a ransom, as this pushes criminals to create a new ransomware.
Fortunately for all victims of NEMTY virus, there is a free decryptor. It allows each victim to decrypt files encrypted with NEMTY ransomware.
To decrypt .NEMTY files, use free NEMTY decryption tool
- Download NEMTY decryptor from the following link.
