What is Im Sorry
Im Sorry is a variant of crypto viruses (malware that encrypt personal files and demand a ransom). It affects all current versions of MS Windows OS such as Windows XP, Windows Vista, Windows 7, Windows 8, Windows 10. This ransomware infection uses a strong encryption algorithm with 2048-bit key to eliminate the possibility of brute force a key that will allow to decrypt encrypted files.
When the ransomware infects a computer, it uses system directories to store own files. To run automatically whenever you turn on your computer, Im Sorry 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 method to define a group of files that will be subjected to encrypting. Encrypted almost all types of files, including common as:
.wpa, .jpeg, .wp, .wmv, .zabw, .rim, .ntl, .wpd, .wcf, .rtf, .rar, .xmind, .big, .vfs0, .csv, .xbdoc, .wsh, .y, .wmo, .d3dbsp, .r3d, .avi, .xld, .0, .xyp, .kdb, .der, .wp7, .xlsm, .raf, .orf, .arch00, .txt, .bay, .odb, .wps, .wm, .wbz, .xlsx, .hvpl, .cdr, .wmd, .ztmp, .w3x, .mrwref, .snx, .ods, .docm, .iwd, .eps, .wbmp, .t13, .hplg, .rgss3a, .dxg, .accdb, .zif, .wav, .x3d, .gho, .wpd, .bc7, .xbplate, .pdf, .lbf, .desc, .sr2, .mov, .qic, .wp4, .kdc, .wot, .erf, .xll, .das, .fsh, .1st, .ncf, .epk, .syncdb, .map, .js, .wbk, .itm, .mpqge, .webp, .css, .odc, .gdb, .xdl, .rw2, .wri, .pptm, .asset, .xx, .dazip, .pptx, .svg, .bkp, .wp6, .menu, .bik, .py, .docx, .bar, .litemod, .xyw, .crw, .cr2, .xxx, .cas, .mlx, .xf, .xdb, .xml, .dmp, .zip, .mcmeta, .wp5, .cer, .jpe, .m4a, .ws, .sidd, .psd, .tor, .m3u, .zip, .ltx, .yml, .dwg, .raw, .iwi, .2bp, .odp, .ff, .xlk, .xwp, .zdb, .vdf, .vpk, .pdd, .wdb, .mdbackup, .sie, .ppt, .mddata, .arw, .xpm, .ibank, .wpl, .psk, .wn, .qdf, .bc6, .p7b, .fpk, .zdc, .doc, .wbm, .srf, .sav, .itl, .x, .dbf, .bsa, .sis, .xls, .3fr, .nrw, .jpg, .mp4, .sb, .sidn, .indd, .ai, .xlsb, .x3f, .yal, .odt, .wpg, .wbc, .db0, .dng, .sum, .sql, .ptx, .cfr, .dba, .mef, .pst, .wpe, .png, .sid, wallet, .t12, .hkdb, .xmmap, .wma, .dcr, .vpp_pc, .wotreplay, .lvl, .webdoc
