A ransomware named Mogranos file virus is another development of cyber criminals. The principle of its functioning and the method of distribution is the same as in the case of the Nelasod, Format, Access and so on, the only difference is the .mogranos extension appended to the photos, documents and music that are affected by it.
Mogranos ransomware was made by cybercriminals to encrypt various files on the user’s PC system using a complex encryption algorithm, which makes it impossible for the user to independently decrypt the affected files that have received .mogranos extension. Mogranos ransomware can encrypt almost all types of files, including common as:
.wbmp, .rtf, .dcr, .litemod, .x3f, .dng, .wmo, .ncf, .pptx, .xlsm, .big, .wmd, .zdb, .layout, .rb, .odp, .ltx, .wot, .cdr, .fsh, .rofl, .xyp, .sidd, .rgss3a, .bay, .bkp, .psk, .gdb, .wmv, .sidn, .wb2, .1st, .kdc, .txt, .esm, .psd, .x, .wsh, .xpm, .xmmap, .cer, .zif, .pkpass, .wp7, .p7c, .wpl, .pdf, .t13, .icxs, .zabw, .wm, .iwi, .wps, .x3f, .sie, .odm, .2bp, .crt, .pem, .r3d, .mddata, .odc, .xlk, .wire, .menu, .itm, .raw, .das, .wotreplay, .pfx, .wma, .epk, .xld, .accdb, .wma, .mdb, .1, .lbf, .nrw, .wsc, .iwd, .wbz, .tor, .wn, .eps, .js, .rar, .sis, .webdoc, .ods, .vtf, .indd, .xbdoc, .wri, .pst, .wsd, .wpt, .zip, .wpg, .xar, .wbc, .xlsx, .xll, .mrwref, .ppt, .mdf, .desc, .tax, .xdl, .py, .css, .dbf, .d3dbsp, .forge, .xxx, .yal, .hkdb, .m2, .xx, .pdd, .png, .vdf, .sr2, .cfr, .xdb, .orf, .ztmp, .dmp, .wcf, .0, .wgz, .blob, .apk, .slm, .dba, .rwl, .xml, .ntl, .ptx, .dxg, .z3d, .itl, .pef, .xls, .sb, .mp4, .wdp, .mcmeta, .zdc, .bik, .wmv, .y, .srf, .xls, .ai, .wdb, .xf, .syncdb, .wbm, .3dm, .bc7, .hkx, .vcf, .xwp, .arw, .doc, .wp6, .xlsb, .rim, .wbk, .der, .wpa, .docm, .gho, .hplg, .p7b, .xlgc, .webp, .zi, .cas, .ibank, .svg, .vpp_pc, .crw, .wpw, .bkf, .w3x, .xbplate, .wav, .mef, .xlsx, .m3u, .sav, .ff, .xmind, .lrf, .3fr, .wp4, .mov, .fos, .vpk, .pak, .srw, .mlx, .map, .3ds, .jpg, .fpk, .csv, .wpd, .snx
Mogranos virus overwrites most of the content of the original files with the encrypted data and appends the .mogranos extension to every encrypted file. The user who sees the files with .mogranos extension understands that they are locked and will remain so until he pays the attackers the required amount of money for obtaining a special key that will recover the files. Usually, the authors of the Mogranos leave a ransom message called ‘_readme.txt’ to users who have infected their computer with this ransomware, indicating the required amount of ransom.

How to decrypt .mogranos files
You can damage files affected with Mogranos ransomware virus, or make them useless forever if you try to find the private key on your own, which is almost impossible in view of its cryptographic complexity. It is very important to know and understand the level of importance of constantly backing up important files to various media, like an USB stick, so that in case of damage to your computer by malware you can always extract a copy of encrypted files.
Never pay the ransom! However, it should be noted that the transferred amount of money to attackers is not yet a guarantee that the victim will receive a code to unlock the affected photos, documents and music. Very often, after receiving the money, cybercriminals impose new requirements for the transfer of an even larger amount of money. It is impossible to predict unambiguously what will be the actions of scammers who designed the Mogranos crypto malware, but it is safe to say that these actions are immoral and illegal.
Of course, it can not be considered that the only correct way out of the situation when your PC is affected with Mogranos crypto malware, will be the payment of ransom, as this only leads to the prosperity of illegal actions of cyber criminals.
