Article created to help you remove the LLTP ransomware infection from your computer and restore files encrypted with the .LLTP file extension.
A ransomware virus, called LLTP ransomware has been reported to cause an immense amount of damage to the computers infected by it. The malware encrypts files on the computers using a combination of AES and RSA encryption ciphers which renders the files to no longer openable. And on top of this, LLTP also archives the files in a .RAR archive that is password-protected. The virus then changes the wallpaper and drops a ReadMe.txt file which has demands on how to pay a hefty ransom fee to get the encrypted files back. In case your computer was infected by the LLTP ransomware infection, we advise you to go through this article and learn how to cope with it.

.LLTP Virus – How Does It Infect
Created by LLTP Locker Team, the cyber-criminals behind this virus may have decided that they will spread it via e-mail spam messages that contain malicious attachments. Usually the e-mails contain deceptive messages in them that aim to trick the user into opening an archive with malicious attachment or click on a URL.
Similar to what appears to be it’s older variant, VenusLocker, the e-mails sent out may pretend that they are containing a receipt, account information or warnings of suspicious activity. In the archives, there may be multiple malicious files that are even legitimate documents which have malicious macros within them. These malicious macros may activate a script which causes the infection. This is why users are advised to take extreme caution and learn how to protect themselves against such e-mails. In order to better protect yourself, please read our related article:
.LLTP Virus – What Does It Do
After infecting users, this possibly re-written VenusLocker variant, begins to drop it’s malicious files on the compromised PC. The files are multiple executable and temp type of files with random names as well as the virus name:
- LLTP3.5.exe
- {random name}.tmp
- LLTP.exe
- {random name}.doc.exe
- {random name}.exe.tmp
- {random name}.exe
- ReadMe.txt
The ReadMe.txt file is dropped on the desktop of the user profile and it has the same content as the original VenusLocker virus, only with the LTTP brand name on it:

The .LTTP Locker Virus Encryption Process
Regarding the encryption of different types of files, this threat takes advantage of multiple different encryption algorithms:
- The Rivest Shamir-Adleman (RSA) cipher which generates unique public and private keys.
- The Advanced Encryption Standard.
Both of the encryption algorithms are used by the LTTP Locker ransomware to target the following file types:
.xls, .xlt, .xlm, .xlsx, .xlsm, .xltx, .xltm, xlsb, .xla, .xlam, .xll, .xlw, .txt, .ini, .php, .html, .css, .py, .c, .cpp, .cc, .h, .cs, .log, .pl, .java, .doc, .dot, .docx, .docm, .dotx, .dotm, .msg, .ppt, .pot, .pps, .pptx, .pptm, .potx, .potm, .ppam, .ppsx, .ppsm, .sldx, .sldm, .class, .jar, .csv, .xml, .dwg, .dxf, .asp, .rtf, .wpd, .docb, .wps .idx, .kwd, .lp2, .ltr, .man, .mbox, .msg, .nfo, .now, .odm, .oft, .pwi, .rng, .rtx, .run, .ssa, .text, .unx, .wbk, .wsh, .7z, .arc, .ari, .arj, .car, .cbr, .cbz, .gz, .gzig, .jgz, .pak, .pcv, .puz, .rev, .sdn, .sen, .sfs, .sfx, .sh, .shar, .bkf, .ade, .adpb, .dic, .cch, .ctt, .dal, .ddc, .ddcx, .dex, .dif, .dii, .itdb, .itl, .kmz, .lcd, .lcf, .mbx, .mdn, .clr, .dbx, .jc, .potm, .ppsm, .prc, .prt, .shw, .std, .ver, .wpl, .xlm, .yps, .1cd, .bck, .html, .bak, .odt, .pst, .log, .mpg, .mpeg, .odb, .wps, .xlk, .mdb, .dxg, .wpd, .wb2, .dbf, .ai, .3fr, .arw, .srf, .sr2, .bay, .shr, .sqx, .tbz2, .tg, .tlz, .vsi, .wad, .war, .xpi, .z02, .z04, .zap, .zipx, .zoo, .ipa, .isu, .jar, .js, .udf, .adr, .ap, .aro, .asa, .ascx, .ashx, .asmx, .odf, .odp, .ods, .pab, .pkb, .pkh, .pot, .potx, .pptm, .psa, .qdf, .qel, .rgn, .rrt, .rsw, .rte, .sdb, .sdc, .sds, .sql, .stt, .tcx, .thmx, .txd, .txf, .upoi, .vmt, .wks, .wmdb, .xl, .xlc, .xlr, .xlsb, .xltx, .ltm, .xlwx, .mcd, .cap, .cc, .cod, .cp, .cpp, .cs, .csi, .dcp, .dcu, .dev, .dob, .dox, .dpk, .dpl, .dpr, .dsk, .dat, .csv, .xml, .spv, .grle, .sv5, .game, .slot, .aaf, .aep, .aepx, .plb, .prel, .prproj, .eat, .ppj, .indl, .indt, .indb, .inx, .idml, .pmd, .xqx, .svg, .as3, .as, .dsp, .eql, .ex, .f90, .fla, .for, .fpp, .jav, .java, .lbi, .owl, .pl, .plc, .pli, .pm, .res, .rsrc, .so, .swd, .tpu, .tpx, .tu, .tur, .vc, .yab, .aip, .amxx, .ape, .api, .mxp, .oxt, .qpx, .qtr, .xla, .xlam, .xll, .xlv, .xpt, .cfg, .cwf, .dbb, .slt, .bp2, .bp3, .bpl, .asp, .indd, .asr, .qbb, .bml, .cer, .cms, .crt, .dap, .htm, .moz, .svr, .url, .wdgt, .abk, .bic, .big, .blp, .bsp, .cgf, .chk, .col, .cty, .dem, .elf, .ff, .gam, .grf, .h3m, .h4r, .iwd, .ldb, .lgp, .lvl, .map, .md3, .mdl, .nds, .pbp, .ppf, .pwf, .pxp, .sad, .sav, .scm, .scx, .sdt, .spr, .sud, .uax, .umx, .unr, .uop, .usa, .usx, .ut2, .ut3, .utc, .utx, .uvx, .uxx, .vmf, .vtf, .w3g, .asf, .pdf, .xls, .docx, .xlsx, .mp3, .waw, .jpg, .jpeg, .txt, .rtf, .doc, .rar, .zip, .psd, .tif, .wma, .gif, .bmp, .ppt, .pptx, .docm, .xlsm, .pps, .ppsx, .ppd, .eps, .png, .ace, .djvu, .tar, .cdr, .max, .wmv, .avi, .wav, .mp4, .pdd, .php, .aac, .ac3, .amf, .amr, .dwg, .dxf, .accdb, .mod, .tax2013, .tax2014, .oga, .ogg, .pbf, .ra, .raw, .saf, .val, .wave, .wow, .wpk, .3g2, .3gp, .3gp2, .3mm, .amx, .rpt, .avs, .bik, .dir, .divx, .dvx, .evo, .flv, .qtq, .tch, .rts, .rum, .rv, .scn, .srt, .stx, .svi, .swf, .trp, .vdo, .wm, .wmd, .wmmp, .wmx, .wvx, .xvid, .3d, .3d4, .3df8, .pbs, .adi, .ais, .amu, .arr, .bmc, .bmf, .cag, .cam, .dng, .ink, .ini, .jif, .jiff, .jpc, .jpf, .jpw, .mag, .mic, .mip, .msp, .nav, .ncd, .odc, .odi, .opf, .qif, .xwd, .abw, .act, .adt, .aim, .ans, .asc, .ase, .bdp, .bdr, .bib, .boc, .crd, .diz, .dot, .dotm, .dotx, .dvi, .dxe, .mlx, .err, .euc, .faq, .fdr, .fds, .gthr, .w3x, .wtd, .wtf, .ccd, .cd, .cso, .disk, .dmg, .dvd, .fcd, .flp, .img, .isz, .mdf, .mds, .nrg, .nri, .vcd, .vhd, .snp, .crw, .cr2, .dcr, .kdc, .erf, .mef, .mrw, .nef, .nrw, .orf, .raf, .rwl, .rw2, .r3d, .srw, .x3f, .der, .pem, .pfx, .p12, .p7b, .p7c, .jfif, .exif, .docb, .xlt, .xltm, .xlw, .ppam, .sldx, .sldm, .class, .db, .pdb, .ptx, .pef
The LTTP virus is very careful as to which types of files it encrypts. It is programmed to avoid any type of files in folders that may compromise the encryption process or the computer system’s health:
→ “Program Files, Program Files (x86), Windows, Python27, Python34, AliWangWang, Avira, wamp, Avira, 360, ATI, Google, Intel, Internet Explorer, Kaspersky Lab, Microsoft Bing Pinyin, Microsoft Chart Controls, Microsoft Games, Microsoft Office, Microsoft.NET, MicrosoftBAF, MSBuild, QQMailPlugin, Realtek, Skype, Reference Assemblies, Tencent, USB Camera2, WinRAR, Windows Sidebar, Windows Portable Devices, Windows Photo Viewer, Windows NT, Windows Media Player, Windows Mail, NVIDIA Corporation, Adobe, IObit, AVAST Software, CCleaner, AVG, Mozilla Firefox, VirtualDJ, TeamViewer, ICQ, java, Yahoo!”
After the encryption process by LTTP Locker has been completed, the files targeted by it are no longer openable. The virus also adds it’s distinctive .LTTP file extension to the encrypted files, making them look like the following:
In addition to simply encrypting the files, this ransomware infection also performs another menace. It puts all the encrypted files in a .RAR archive which it protects with a password, making decryption even more difficult.
