Update September 2017 The newest malware spam campaign revolving around the .Lukitus variant of the Locky virus is massive. Over 23 million users are reported to have received these e-mails and the victims are many. The campaign mainly spoofs the famous Google service “DropBox“. The email contents look like an official e-mail from DropBox and that is considered phishing. However, it appears that this is not the only type of e-mail that users have received. Beware as there are many variants. Below you can see more details about the DropBox e-mails, which seem to be currently the most spread.

You will receive an email message that uses the DropBox logo, a sender email address that looks like its sent from that service and it looks like in the following screenshot:

The email states the following:

Hi [your name here],

We just need to verify your email address before your sign up is complete!

Verify your email
Happy Dropboxing!

If you fall for it and click on the designated link, you will find yourself on another online page that looks like this:

If you click on the second link as well, then you get the .Lukitus variant of the Locky ransomware “dropped” on your PC and it will encrypt your files. Be wary of what you click on, and never trust emails that are from unknown entities or are received surprisingly at times you weren’t expect them. In the next section you will see what other ways exist for the virus to spread and more technical details about the ransomware as a whole.

.Lukitus File Virus – Distribution Methods

.Lukitus File Virus as a new version of Locky ransomware, is distributing itself via a massive e-mail spam campaign, which according to researchers has now reached over 1000 emails. At the time of writing of this article, there are not many reports of victims. However, the e-mail has one of the following two subjects:

  • PAYMENT
  • Emailing [random letters and numbers]

Such an e-mail will contain a .zip, .rar or .7z attachment – example: July-August2017.rar. When the attachment is opened, it will look like a normal document. That file has a JS trigger (and could contain a .jse file) and the said script will download the malware. You can see a sample with one such file on the VirusTotal service right here:

In the email, the attachment inside the .zip file will probably have one of the following extensions:

→.doc, .docx, .xls, .xlsx, .jpg, .tiff, .pdf, .jpg

So, that will make the file look like a document or a picture. Command&Control (C2) Server will be pinged, and that server will download Locky’s malicious executable in an encrypted form so it can try to bypass security software. The Necurs Botnet and the BlankSlate malware spam campaign have been reported to spread the e-mails with malicious attachment for Locky’s .lukitus variant.

Below you can see the domains spreading this variant of the ransomware:

List with some of the payload download sites

Notice! The above list with domains is for purely informational purposes and it is strongly advised against the opening of any of them, because they will download the virus onto your computer.

Here is the body text of most current e-mail spam campaigns:

Your message is ready to be sent with the following file or link

attachments:

Payment_201708-838

Note: To protect against computer viruses, e-mail programs may prevent

sending or receiving certain types of file attachments. Check your e-mail

security settings to determine how attachments are handled.

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 inform yourself better about methods for fighting such malware threats.

.Lukitus File Virus – Technical Information

The .lukitus File Virus is actually the newest variant of Locky ransomware. Dubbed after the extension .lukitus that it places to encrypted files, this version of the infamous cryptovirus has been discovered to spread not only with the help of its old malicious domains, but with some new 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. 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:
http://en.wildpedia.org/wiki/RSA_(cryptosystem)
http://en.wikipedia.org/wiki/Advanced_Encryption_Standard

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

As clearly seen from the Tor payment page, the .Lukitus file virus wants you to pay 0.5 Bitcoin, which equals to nearly 2060 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 can recover your data upon payment, or that you won’t get your computer infected once more in the future. Moreover, giving money to cybercriminals this way could be interpreted as supporting them financially, and could also motivate them to keep committing similar crimes, such as creating ransomware viruses. That is evidently true as new variants of Locky ransomware keep coming out.

.Lukitus File Virus – Encryption Process

The .lukitus File Virus is dubbed like that by victims, because it appends the .lukitus 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, and namely the following:

→.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. Encrypted files will be renamed with a logical sequence of numbers stemming from your ID number. For instance, such a file will look like G93562L1-K86Z-019J-47N5V911-87QP4TK6FHXM.lukitus.

The Locky cryptovirus has a highly probability 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. That makes the encryption process of the virus even more viable.
