If your photos, documents and music does not open normally, locked added at the end of their name then your personal computer is infected with a new Locked ransomware from a family of file-encrypting ransomware. Once opened, it have encrypted all personal files stored on a computer drives and attached network drives.
The Locked ransomware virus uses a strong encryption algorithm with 2048-bit key. When the virus encrypts a file, it will add the locked extension to each encrypted file. Once the ransomware infection finished enciphering of all documents, photos and music, it will drop a file named “readme.txt” with tutorial on how to decrypt all personal files.

The ransomnote encourages victim to contact Locked’s creators in order to decrypt all files. These persons will require to pay a ransom (usually demand for $300-1000 in Bitcoins). We don’t recommend paying a ransom, as there is no guarantee that you will be able to decrypt your personal files. Especially since you have a chance to restore your photos, documents and music for free using free tools such as ShadowExplorer and PhotoRec.
Therefore it’s very important to follow the guidance below as soon as possible. The step by step guidance will help you to get rid of Locked ransomware infection. What is more, the instructions below will help you restore encrypted personal files for free.
What is Locked virus
Locked is a variant of crypto viruses (malicious software that encrypt personal files and demand a ransom). It affects all current versions of Windows OS such as Windows XP, Windows Vista, Windows 7, Windows 8, Windows 10. This virus uses a strong encryption algorithm with 2048-bit key to eliminate the possibility of brute force a key which will allow to decrypt encrypted personal files.
When the ransomware infection infects a computer, it uses system directories to store own files. To run automatically whenever you turn on your machine, Locked ransomware virus creates a registry entry in Windows: sections HKCU \ Software \ Microsoft \ Windows \ CurrentVersion \ Run, HKCU \ Software \ Microsoft \ Windows \ CurrentVersion \ RunOnce, HKCU \ Software \ Microsoft \ Windows \ CurrentVersion \ Run, HKCU \ Software \ Microsoft \ Windows \ CurrentVersion \ RunOnce.
Immediately after the launch, the ransomware scans all available drives, including network and cloud storage, to determine which files will be encrypted. The virus uses the file name extension, as a way to define a group of files that will be subjected to encrypting. Encrypted almost all types of files, including common as:
.xx, .odc, .pst, .srf, .xlgc, .sql, .wmv, .wsc, .wp6, .zabw, .bsa, .css, .epk, .wotreplay, .dba, .ptx, .bc6, .hvpl, .xxx, .1st, .hplg, .wsd, .hkx, .arch00, .yml, .wps, .wpb, .rtf, .7z, .wmv, .qic, .cfr, .sis, .t13, .apk, .wmd, .wma, .forge, .vpk, .gho, .xyw, .zdb, .bik, .xlsx, .webp, .raf, .p7c, .crw, .pptm, .pef, .z, .xdl, .js, .wp4, .mcmeta, .ods, .itl, .m2, .xyp, .lrf, .asset, .cr2, .webdoc, .yal, .zdc, .wbd, .wn, .wpd, .ws, .pem, .d3dbsp, .upk, .xy3, .esm, .tor, .3dm, .ncf, .mdb, .sidd, wallet, .sr2, .gdb, .xmind, .mlx, .wpg, .wp7, .pak, .svg, .dxg, .xll, .xlsb, .mpqge, .zip, .wps, .wav, .vcf, .xbdoc, .zif, .jpe, .wire, .ztmp, .arw, .odt, .tax, .xls, .png, .rgss3a, .wm, .mp4, .wp, .syncdb, .1, .itm, .dbf, .itdb, .iwd, .sid, .vtf, .crt, .sum, .sie, .lvl, .rwl, .wmf, .db0, .fsh, .jpeg, .doc, .xar, .0, .sb, .dazip, .psd, .csv, .m3u, .ai, .wcf, .pkpass, .wot, .bkf, .menu, .mov, .bar, .wpe, .ltx, .wpa, .xlsm, .pptx, .cdr, .mdbackup, .layout, .accdb, .orf, .wbk, .wpl, .mdf, .xlk, .ybk, .xwp, .pfx, .bc7, .p7b, .kdc, .das, .odm, .dwg, .mddata, .wpt, .wri, .hkdb, .wpd, .der, .lbf, .ppt, .srw, .kf, .xpm, .snx, .zw, .eps, .erf, .cas, .iwi, .xld, .x3d, .bkp, .py, .odb, .zip, .r3d, .xml, .zi, .blob, .wbz, .ff, .nrw, .icxs, .map, .xdb, .dng, .w3x, .dmp, .wbm, .wgz, .xls, .psk, .raw, .y, .dcr, .rar, .pdf, .wdp, .fpk, .ibank, .indd, .vfs0, .pdd, .xf, .3fr, .rb, .xlsm, .rim, .re4, .kdb, .ysp, .m4a, .cer, .z3d, .txt, .ntl, .docx, .litemod, .vdf, .x3f, .xlsx, .fos, .x, .mef, .bay, .xmmap, .2bp, .flv, .sav, .desc, .wb2, .t12, .jpg, .wsh, .mrwref, .3ds, .odp, .rofl, .wma, .p12, .x3f, .docm, .slm, .wp5, .sidn, .rw2, .big, .xbplate, .wpw, .qdf, .wbmp, .wmo, .wbc, .vpp_pc, .wdb, .avi
Once a file is encrypted, its extension changed to locked. Next, the ransomware infection creates a file called “readme.txt”. This file contain guidance on how to decrypt all encrypted files.
The Locked virus actively uses scare tactics by giving the victim a brief description of the encryption algorithm and showing a ransomnote on the desktop. It is trying to force the user of the infected personal computer, do not hesitate to pay a ransom, in an attempt to recover their photos, documents and music.
How to decrypt .locked files
Currently there is no available method to decrypt .locked files, but you have a chance to recover encrypted files for free. The ransomware repeatedly tells the victim that uses RSA-2048 key (AES 256-bit encryption method). What does it mean to decrypt the files is impossible without the private key. Use a “brute forcing” is also not a way because of the big length of the key. Therefore, unfortunately, the only payment to the developers of the Locked ransomware entire amount requested – the only way to try to get the decryption key and decrypt all your files.
There is absolutely no guarantee that after pay a ransom to the authors of the Locked 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.
