.Loptr File Virus Removal – Restore Files

This article will help you remove the .Loptr File Virus effectively. Follow the ransomware removal instructions provided at the end.

.Loptr File Virus is actually a new Locky ransomware variant that puts that extension to locked files. The new variant gets inside your computer system via spam e-mails with PDF attachments. Opening such an attachment loads a Microsoft Word document with a hidden macro command inside, that if you enable, the malware will infect your PC and encrypt your files. No real changes are present in the ransom note as you can see on the right of this paragraph. Continue to read and see if you can potentially restore your files.

.Loptr File Virus – Distribution Methods

.Loptr File Virus as a new iteration of Locky ransomware, also has new ways to distribute itself. The most prominent and widespread distribution way is quite complex. Although it requires social engineering to complete the attack, it is still effective. That method starts with the spread of the malware via spam e-mails. Such an e-mail will contain a 58 KB file that seems like a PDF document. You can see examples below:


Image Source: FireEye.com

Upon opening the PDF file, you will find out that there is a Microsoft Word document embedded inside, which looks like the following:

Clicking on “Enable Editing” and then on “Enable Content” will activate a hidden macro command and a PowerShell command, too. The PowerShell command will ping a Command&Control (C2) Server, and that server will download Locky’s malicious executable in an encrypted form so it can try to bypass Antivirus programs.

However, AV vendors have already taken precautions against the latest files that have been detected to be associated with the .Loptr File Virus threat as you can see from the images down here:

Before opening any file from the Internet, always perform a scan with a security program. You should read the ransomware preventing tips in our forum to educate yourself better about methods for fighting such malware threats.

.Loptr File Virus – Technical Information

The .Loptr File Virus is actually the latest variant of Locky ransomware. Dubbed after the extension .loptr that it places to encrypted files, this version of the nefarious cryptovirus has been discovered to spread not only with the help of its old malicious domains, but with many newly-set ones.

The Locky ransomware also makes entries in the Windows Registry to achieve a higher level of persistence. Registry entries of that caliber are typically designed to start the virus automatically with every launch of the Windows Operating System or even repress and tamper with processes.

The message with the ransom payment instructions appears to be unchanged and is stored in two files yet again – one in a .jpg, the other in a .html. Both have identical names that begin with loptr- and end with 4 symbols. You can preview the picture that is placed as your Desktop background below:

The ransom message reads the following:

=*~*I+_=

-+H=I-~I_-=+*$

-=~$*I_=.*

!!! IMPORTANT INFORMATION !!!!

All of your files are encrypted with RSA-2048 and AES-128 ciphers.

More information about the RSA and AES can be found here:

Decrypting of your files is only possible with the private key and decrypt program, which is on our secret server.

To receive your private key follow one of the links:

If all of this addresses are not available, follow these steps:

1. Download and install Tor Browser: https://www.torproject.org/downIoad/download-easy.html
2. After a successful installation, run the browser and wait for initialization.

3. Type in the address bar: g46mbrrzpfszonuk.onion

4. Follow the instructions on the site.

As clearly seen from the Tor payment page, the .Loptr file virus wants you to pay 0.5 Bitcoin, which equals to nearly 926 US dollars at the moment of writing this article. However, you should NOT under any circumstances pay anything to the cybercriminals. Nobody can guarantee that you will get your files restored upon payment, nor that you won’t get your PC infected again in the future. Furthermore, financially supporting cybercriminals could motivate them to keep doing crimes, such as the creation of ransomware viruses (as it has in the past with these malware developers).

.Loptr File Virus – Encryption Process

The .Loptr File Virus is dubbed like that by users, because it appends the .loptr extension to all encrypted files. As malware researchers have confirmed that it is indeed a new variant of the Locky Ransomware, it is most likely seeking to encrypt files with extensions such as its previous iterations, namely:

→.001, .002, .003, .004, .005, .006, .007, .008, .009, .010, .011, .123, .1cd, .3dm, .3ds, .3fr, .3g2, .3gp, .3pr, .602, .7z, .7zip, .ARC, .CSV, .DOC, .DOT, .MYD, .MYI, .NEF, .PAQ, .PPT, .RTF, .SQLITE3, .SQLITEDB, .XLS, .aac, .ab4, .accdb, .accde, .accdr, .accdt, .ach, .acr, .act, .adb, .adp, .ads, .aes, .agdl, .ai, .aiff, .ait, .al, .aoi, .apj, .apk, .arw, .asc, .asf, .asm, .asp, .aspx, .asset, .asx, .avi, .awg, .back, .backup, .backupdb, .bak, .bank, .bat, .bay, .bdb, .bgt, .bik, .bin, .bkp, .blend, .bmp, .bpw, .brd, .bsa, .cdf, .cdr, .cdr3, .cdr4, .cdr5, .cdr6, .cdrw, .cdx, .ce1, .ce2, .cer, .cfg, .cgm, .cib, .class, .cls, .cmd, .cmt, .config, .contact, .cpi, .cpp, .cr2, .craw, .crt, .crw, .cs, .csh, .csl, .csr, .css, .csv, .d3dbsp, .dac, .das, .dat, .db, .db3, .db_journal, .dbf, .dbx, .dc2, .dch, .dcr, .dcs, .ddd, .ddoc, .ddrw, .dds, .der, .des, .design, .dgc, .dif, .dip, .dit, .djv, .djvu, .dng, .doc, .docb, .docm, .docx, .dot, .dotm, .dotx, .drf, .drw, .dtd, .dwg, .dxb, .dxf, .dxg, .edb, .eml, .eps, .erbsql, .erf, .exf, .fdb, .ffd, .fff, .fh, .fhd, .fla, .flac, .flf, .flv, .flvv, .forge, .fpx, .frm, .fxg, .gif, .gpg, .gray, .grey, .groups, .gry, .gz, .hbk, .hdd, .hpp, .html, .hwp, .ibank, .ibd, .ibz, .idx, .iif, .iiq, .incpas, .indd, .iwi, .jar, .java, .jnt, .jpe, .jpeg, .jpg, .js, .kc2, .kdbx, .kdc, .key, .kpdx, .kwm, .laccdb, .lay, .lay6, .lbf, .ldf, .lit, .litemod, .litesql, .log, .ltx, .lua, .m2ts, .m3u, .m4a, .m4p, .m4u, .m4v, .mapimail, .max, .mbx, .md, .mdb, .mdc, .mdf, .mef, .mfw, .mid, .mkv, .mlb, .mml, .mmw, .mny, .moneywell, .mos, .mov, .mp3, .mp4, .mpeg, .mpg, .mrw, .ms11, .msg, .myd, .n64, .nd, .ndd, .ndf, .nef, .nk2, .nop, .nrw, .ns2, .ns3, .ns4, .nsd, .nsf, .nsg, .nsh, .nvram, .nwb, .nx2, .nxl, .nyf, .oab, .obj, .odb, .odc, .odf, .odg, .odm, .odp, .ods, .odt, .ogg, .oil, .onetoc2, .orf, .ost, .otg, .oth, .otp, .ots, .ott, .p12, .p7b, .p7c, .pab, .pages, .pas, .pat, .pcd, .pct, .pdb, .pdd, .pdf, .pef, .pem, .pfx, .php, .pif, .pl, .plc, .plus_muhd, .png, .pot, .potm, .potx, .ppam, .pps, .ppsm, .ppsx, .ppt, .pptm, .pptx, .prf, .ps, .psafe3, .psd, .pspimage, .pst, .ptx, .pwm, .py, .qba, .qbb, .qbm, .qbr, .qbw, .qbx, .qby, .qcow, .qcow2, .qed, .r3d, .raf, .rar, .rat, .raw, .rb, .rdb, .re4, .rm, .rtf, .rvt, .rw2, .rwl, .rwz, .s3db, .safe, .sas7bdat, .sav, .save, .say, .sch, .sd0, .sda, .sdf, .sh, .sldm, .sldx, .slk, .sql, .sqlite, .sqlite3, .sqlitedb, .sr2, .srf, .srt, .srw, .st4, .st5, .st6, .st7, .st8, .stc, .std, .sti, .stm, .stw, .stx, .svg, .swf, .sxc, .sxd, .sxg, .sxi, .sxm, .sxw, .tar, .tar.bz2, .tbk, .tex, .tga, .tgz, .thm, .tif, .tiff, .tlg, .txt, .uop, .uot, .upk, .vb, .vbox, .vbs, .vdi, .vhd, .vhdx, .vmdk, .vmsd, .vmx, .vmxf, .vob, .wab, .wad, .wallet, .wav, .wb2, .wk1, .wks, .wma, .wmv, .wpd, .wps, .x11, .x3f, .xis, .xla, .xlam, .xlc, .xlk, .xlm, .xlr, .xls, .xlsb, .xlsm, .xlsx, .xlt, .xltm, .xltx, .xlw, .xml, .ycbcra, .yuv, .zip

The encryption algorithm that is claimed to be used by Locky in all of its ransom notes is RSA-2048 with AES 128-bit ciphers.

The Locky cryptovirus is probably set to delete the Shadow Volume Copies from the Windows Operating System by executing the following command:

→vssadmin.exe delete shadows /all /Quiet

The command eliminates one of the prominent ways for file restoration on your computer system, thus making the encryption process even more viable.
