Dodoc virus encrypts almost of files, including common as:
.webp, .vfs0, .forge, .odm, .xlsx, .bar, .bay, .der, .dba, .2bp, .wdp, .arch00, .wsh, .zdb, .xdl, .wpd, .xar, .wpw, .vcf, .das, .rtf, .x, .wb2, .y, .x3f, .pfx, .dng, .pptm, .3fr, .map, .erf, .psk, .wp, .tor, .desc, .7z, .pst, .odc, .raw, .dwg, .png, .xbplate, .jpg, .xlsm, .rim, .wmo, .kdc, .jpe, .m3u, .pdf, .wma, .crt, .vdf, .xls, .crw, .nrw, .wp6, .zabw, .xlgc, .z, .esm, .wpd, .hplg, .3ds, .mdf, .sidd, .qdf, .zif, .csv, .xmmap, .mpqge, .doc, .bkp, .xbdoc, .txt, .p7c, .m4a, .wbd, .docx, .rw2, .xls, .wmf, .slm, .itl, .snx, .xyw, .bsa, .pkpass, .wav, .rb, .zdc, .ltx, .jpeg, .ptx, wallet, .wbmp, .cdr, .big, .sr2, .xy3, .zi, .t12, .lbf, .gho, .rgss3a, .zip, .wp5, .ibank, .fpk, .p12, .srf, .ods, .iwd, .cfr, .fsh, .hvpl, .wotreplay, .icxs, .mrwref, .wdb, .w3x, .sis, .pem, .re4, .1st, .hkx, .wpg, .ntl, .accdb, .kdb, .cas, .wbz, .mov, .wn, .wsd, .mcmeta, .css, .odt, .cer, .sidn, .wbk, .sum, .mddata, .wma, .dazip, .wps, .wbc, .rofl, .vpk, .wpa, .pak, .d3dbsp, .webdoc, .ybk, .sid, .wm, .xx, .ws, .xlsx, .mef, .pptx, .menu, .bik, .yal, .apk, .avi, .wmv, .r3d, .itdb, .wpt, .svg, .wcf, .wpb, .wot, .gdb, .srw, .syncdb, .ztmp, .t13, .yml, .ysp, .ai, .mdbackup, .indd, .vpp_pc, .wmd, .wri, .qic, .kf, .pef, .litemod, .layout, .ppt, .asset, .bc6, .upk, .xmind, .rar, .1, .xml, .orf, .m2, .zip, .x3f, .flv, .bc7, .xll, .sql, .fos, .blob, .dxg, .dmp, .mdb, .odp, .wgz, .docm, .bkf, .db0, .0, .xxx, .raf, .p7b, .xlsb, .tax, .sav, .dbf, .wps, .mlx, .js, .xlk, .sie, .wbm, .itm, .pdd, .cr2, .lvl, .wp7, .wmv, .odb, .dcr, .xpm, .xwp, .lrf, .iwi, .eps, .arw, .psd, .xyp, .sb, .x3d, .wp4, .wpl, .z3d, .vtf, .xlsm, .wpe, .xf, .ff, .hkdb, .wire, .xdb, .mp4, .zw, .py
Files which are locked by Dodoc receive the .dodoc extension and become inaccessible to the victim. In the place where the photos, documents and music were locked by the Dodoc virus, a ransom note appears with instructions that there was a lock of archives, tables, video materials, photos and documents, or other files important to the victim. The ransom note also states that the victim must transfer money to scammers to obtain a special code key that he can use to decrypt the encrypted files that have received the .dodoc extension. If the victim has the opportunity to transfer money to purchase this key and/or decryption utility within 72 hours, he can pay only half of the specified amount.
