Security specialists discovered a new variant of ransomware which named ‘Novasof file virus‘. It appends the .novasof file extension to encrypted file names. Here’s everything you need to know about this ransomware, how to remove ‘Novasof virus’ and how to restore (decrypt) encrypted personal files for free.
Novasof ransomware was made by scammers to lock various files on the user’s PC, using very strong hybrid encryption with a large key, that makes it impossible for the user to independently unlock the locked files that have received .novasof extension. Novasof can encrypt almost all types of files, including common as:
.iwi, .xlsm, .icxs, .sql, .mdb, .zi, .vpk, .layout, .dng, .xlgc, .pfx, .3dm, .sr2, wallet, .xlsx, .crw, .wbz, .ai, .wotreplay, .webdoc, .lvl, .webp, .ncf, .das, .pptx, .w3x, .odc, .yal, .t12, .sum, .apk, .docx, .syncdb, .xml, .xyp, .xlk, .odm, .xdb, .xlsb, .xlsm, .wp4, .wire, .zabw, .rw2, .vdf, .jpg, .qic, .odb, .x, .jpe, .zdc, .bik, .sidd, .bay, .xls, .mlx, .wp7, .lrf, .cr2, .xdl, .wsc, .sid, .pptm, .hplg, .wb2, .bsa, .kdb, .x3d, .wri, .zif, .sis, .png, .tax, .odp, .1, .mov, .wdp, .arw, .py, .ltx, .wp, .wgz, .mp4, .js, .qdf, .wn, .rgss3a, .xmmap, .2bp, .raf, .menu, .cfr, .arch00, .css, .pef, .yml, .dcr, .psk, .rofl, .sb, .7z, .p7b, .forge, .ff, .gho, .wm, .sav, .wpt, .t13, .vfs0, .epk, .p12, .cas, .mef, .hkx, .p7c, .fos, .zip, .wpl, .x3f, .pem, .xy3, .hvpl, .cdr, .fpk, .3ds, .xwp, .eps, .pak, .cer, .pdd, .ws, .wpe, .xbplate, .zdb, .dxg, .svg, .ppt, .m3u, .dba, .lbf, .wma, .rim, .z, .ybk, .vtf, .doc, .xpm, .rtf, .big, .crt, .blob, .accdb, .erf, .mpqge, .dbf, .y, .wbm, .ibank, .xls, .wbd, .xll, .vpp_pc, .kf, .rwl, .xx, .litemod, .upk, .wp5, .xar, .gdb, .bc6, .wpd, .jpeg, .docm, .raw, .wmv, .xyw, .xmind, .txt, .zw, .mdbackup, .wav, .kdc, .orf, .vcf, .mdf, .ysp, .der, .xbdoc, .m2, .wot, .wps, .z3d, .bkf, .rar, .csv, .mrwref, .dazip, .tor, .r3d, .ztmp, .desc, .d3dbsp, .wma, .wpa, .hkdb, .itl, .pst, .wpb, .indd, .ntl, .bkp, .xlsx, .dmp, .map, .iwd, .mcmeta, .wmv, .3fr, .wps, .xld, .wbmp, .wsh, .sidn, .wbk, .wbc, .wdb, .sie, .zip, .wmd, .snx, .srw, .xf, .wpd, .rb, .mddata, .nrw, .esm, .bc7, .ods, .wpw, .srf, .1st
Once on the PC, the Novasof virus completely encrypts the files so that the victim can not open them. In this case, the only option to restore the files is to pay a ransom to scammers who are Novasof developers and offer a key to decrypt all affected files. The developers of crypto virus have done everything possible to be sure that the user will immediately determine what exactly is affected with its crypto malware, as the locked files will have the .novasof extension. Also, online criminals leave a ransom note called ‘_readme.txt’ indicating the amount of money which user need to make to decrypt the files.
