This article has been created to show you how to remove the .payforunlock file virus and restore AES encrypted files by CryptoGod (Information Security) ransomware.

The beginning of June 2017 has been characterized with many new ransomware viruses being released. One of those, dubbed CryptoGod or also known as Information Security ransomware encrypts the files on computers infected by it via the AES algorithm. The Information Security virus then adds the .payforunlock file extension and displays a ransom note with a deadline timer of 12 hours in which the victim must pay 0.03 BTC to get the files back. In case the deadline is not met, the virus increases the ransom to 0.05 BTC. In case your computer has been infected by the CryptoGod ransomware virus, we suggest you to read the following article.

Data Recovery ToolWindows Data Recovery by Stellar Phoenix Notice! This product scans your drive sectors to recover lost files and it may not recover 100% of the encrypted files, but only few of them, depending on the situation and whether or not you have reformatted your drive.

How is Information Security Ransomware Spread

In order to infect as many victims as it can, the Information Security virus may spread via multiple different methods:

  • As spammed e-mail messages that contain the infection file in the form of either attachment or malicious web links.
  • As fake updates by other malware that can have previously infected your computer.
  • As malicious files disguised as setups, key generators and license activators.

Information Security Virus – Analysis

As soon as the Information Security malware has already infected your computer, the virus drops a malicious file, named “Reciept {the date}.exe”. This executable may connect to third-party hosts and further drop more malicious files on the infected computer of the victim. The files may reside in the following Windows directories:

  • %AppData%
  • %Roaming%
  • %Local%
  • %LocalLow%

In addition to this activity the Information Security ransomware may also perform multiple other actions on the computers infected by it:

  • Delete the shadow volume copies via the vssadmin and bcedit administrative Windows commands.
  • Add registry value strings In the infected computer’s Registry Editor to run files automatically or change settings.
  • Drop it’s ransom note and automatically open it.

The ransom note of the Information Security ransomware has the following:

“Your Personal Files has been Encrypted and Locked
Your documents, photos, databases and other important files have been encrypted with strongest encryption and locked with unique key, generated for this computer.
Private decryption key is stored on a secret Internet server and nobody can decrypt your files until you pay and obtain the private key.
Caution: Removing of CryptoGod will not restore access ti your encrypted files.

Information Security Virus Encryption Process

The encryption process of this ransomware virus is conducted primarily via the AES encryption algorithm, also known as Advanced Encryption Algorithm. This cipher has several encryption modes, each of which aims to replace a portion or blocks of data from the original files to make those types of files no longer able to be opened. The files which Information Security ransomware targets for encryption are several hundred types of different documents, pictures, music, videos, etc. The primary file types which are targeted are the following:

→ .#vc, .$ac, ._vc, .00c, .07g, .07i, .08i, .09i, .09t, .10t, .11t, .123, .13t, .1pa, .1pe, .2011, .2012, .2013, .2014, .2015, .2016, .2017, .210, .3dm, .3ds, .3g2, .3gp, .3me, .3pe, .500, .7z, .aac, .aaf, .ab4, .ac2, .acc, .accd, .ach, .aci, .acm, .acr, .aep, .aepx, .aes, .aet, .afm, .ai, .aif, .amj, .as, .as3, .asc, .asf, .asm, .asp, .asx, .ati, .avi, .back, .bak, .bat, .bay, .bc8, .bc9, .bd2, .bd3, .bgt, .bk2, .bkf, .bmp, .bpf, .bpw, .brd, .brw, .btif, .bz2, .c, .cal, .cat, .cb, .cd, .cdf, .cdr, .cdt, .cdx, .cf8, .cf9, .cfdi, .cfp, .cgm, .cgn, .ch, .chg, .cht, .clas, .clk, .cmd, .cmx, .cnt, .cntk, .coa, .cpp, .cpt, .cpw, .cpx, .crt, .cs, .csl, .csr, .css, .csv, .cur, .cus, .d07, .dac,.dat, .db, .dbf, .dch, .dcr, .ddd, .dds, .defx, .der, .des, .dgc, .dif, .dip, .djv, .djvu, .dng, .doc, .docb, .docm, .docx, .dot, .dotm, .dotx, .drw, .ds4, .dsb, .dsf, .dtau, .dtd, .dtl, .dwg, .dxf, .dxi, .ebc, .ebd, .ebq, .ec8, .efs, .efsl, .efx, .emd, .eml, .emp, .ens, .ent, .epa, .epb, .eps, .eqb, .ert, .esk, .ess, .esv, .etq, .ets, .exp, .fa1, .fa2, .fca, .fcpa, .fcpr, .fcr, .fef, .ffd, .fim, .fla, .flac, .flv, .fmv, .fon, .fpx, .frm, .fx0, .fx1, .fxr, .fxw, .fyc, .gdb, .gem, .gfi, .gif, .gnc, .gpc, .gpg, .gsb, .gto, .gz, .h, .h10, .h11, .h12, .hbk, .hif, .hpp, .hsr, .html, .hts, .hwp, .i2b, .iban, .ibd, .ico, .idml, .iff, .iif, .img, .imp, .indb, .indd, .indl, .indt, .ini, .int?, .intu, .inv, .inx, .ipe, .ipg, .itf, .jar, .java, .jng, .jp2, .jpeg, .jpg, .js, .jsd, .jsda, .jsp, .kb7, .kd3, .kdc, .key, .kmo, .kmy, .lay, .lay6, .lcd, .ldc, .ldf, .ldr, .let, .lgb, .lhr, .lid, .lin, .lld, .lmr, .log, .lua, .lz, .m, .m10, .m11, .m12, .m14, .m15, .m16, .m3u, .m3u8, .m4a, .m4u, .m4v, .mac, .max, .mbsb, .md, .mda, .mdb, .mdf, .mef, .mem, .met, .meta, .mhtm, .mid, .mkv, .ml2, .ml9, .mlb, .mlc, .mmb, .mml, .mmw, .mn1, .mn2, .mn3, .mn4, .mn5, .mn6, .mn7, .mn8, .mn9, .mne, .mnp, .mny, .mone, .mov, .mp2, .mp3, .mp4, .mpa, .mpe, .mpeg, .mpg, .mql, .mrq, .ms11, .msg, .mwi, .mws, .mx0, .myd, .mye, .myi, .myox, .n43, .nap, .nd, .nef, .nl2, .nni, .npc, .nv, .nv2, .oab, .obi, .odb, .odc, .odg, .odm, .odp, .ods, .odt, .oet, .ofc, .ofx, .old, .omf, .op, .orf, .ost, .otg, .otp, .ots, .ott, .p08, .p12, .p7b, .p7c, .paq, .pas, .pat, .pcd, .pcif, .pct, .pcx, .pd6, .pdb, .pdd, .pdf, .pem, .per, .pfb, .pfd, .pfx, .pg, .php, .pic, .pl, .plb, .pls, .plt, .pma, .pmd, .png, .pns, .por, .pot, .potm, .potx, .pp4, .pp5, .ppam, .ppf, .ppj, .pps, .ppsm, .ppsx, .ppt, .pptx, .pr0, .pr1, .pr2, .pr3, .pr4, .pr5, .prel, .prf, .prn, .prpr, .ps, .psd, .psp, .pst, .ptb, .ptdb, .ptk, .ptx, .pvc, .pxa, .py, .q00, .q01, .q06, .q07, .q08, .q09, .q43, .q98, .qb1, .qb20, .qba, .qbb, .qbi, .qbk, .qbm, .qbmb, .qbmd, .qbo, .qbp, .qbr, .qbw, .qbx, .qby, .qbz, .qch, .qcow, .qdf, .qdfx, .qdt, .qel, .qem, .qfi, .qfx, .qif, .qix, .qme, .qml, .qmt, .qmtf, .qnx, .qob, .qpb, .qpd, .qpg, .qph, .qpi, .qsd, .qsm, .qss, .qst, .qtx, .quic, .quo, .qw5, .qwc, .qwmo, .qxf, .r3d, .ra, .raf, .rar, .raw, .rb, .rcs, .rda, .rdy, .reb, .rec, .resx, .rif, .rm, .rpf, .rsspptm, .rtf, .rtp, .rw2, .rwl, .rz, .s12, .s7z, .saf, .saj, .say, .sba, .sbc, .sbd, .sbf, .scd, .sch, .sct, .sdf, .sdy, .seam, .ses, .set, .shw, .sic, .skg, .sldm, .sldx, .slk, .slp, .sql, .sqli, .sr2, .srf, .ssg, .stc, .std, .sti, .stm, .str, .stw, .svg, .swf, .sxc, .sxd, .sxi, .sxm, .sxw, .t00, .t01, .t02, .t03, .t04, .t05, .t06, .t07, .t08, .t09, .t10, .t11, .t12, .t13, .t14, .t15, .t99, .ta1, .ta2, .ta4, .ta5, .ta6, .ta8, .ta9, .tar, .tax, .tax0, .tax1, .tax2, .tb2, .tbk, .tbp, .tdr, .text, .tfx, .tga, .tgz, .tif, .tiff, .tkr, .tlg, .tom, .tpl, .trm, .trn, .tt10, .tt11, .tt12, .tt13, .tt14, .tt15, .tt20, .ttf, .txf, .txt, .u08, .u10, .u11, .u12, .uop, .uot, .v30, .vb, .vbpf, .vbs, .vcf, .vdf, .vdi, .vmb, .vmdk, .vmx, .vnd, .vob, .vsd, .vyp, .vyr, .wac, .wav, .wb2, .wi, .wk1, .wk3, .wk4, .wks, .wma, .wmf, .wmv, .wpd, .wpg, .wps, .x3f, .xaa, .xcf, .xeq, .xhtm, .xla, .xlam, .xlc, .xlk, .xll, .xlm, .xlr, .xls, .xlsb, .xlsm, .xlsx, .xlt, .xltm, .xltx, .xlw, .xml, .xpm, .xqx, .yuv, .zdb, .ziparc, .zipx, .zix, .zka

After the encryption process of the Information Security ransomware virus is completed, the virus adds the .payforunlock file extension to the encrypted files. They may look like the following:
