.Asasin File Virus – Update November 2017
The .Asasin Locky Version has updated its domains that spread the payload these last couple of days. From November the newest domains are going to redirect you until eventually you land on the final payload page “ https://hobbystube(.)net/dkjshfg643” and execute the malware QTLoader which delivers Locky. Below, inside the accordion, you can preview the latest distribution domains for the cryptovirus:
All of the above domains and links, lead to Locky (.asasin).
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.
.Asasin File Virus – Distribution Techniques
The main variant of the .Asasin File Virus propagates itself via e-mail spam campaigns. The e-mail has a subject that reads “Document invoice_21637_sign_and_return.pdf is complete”. Inside there is a .7z or a .7zip attached file which is not properly added to the email and seen as a base64 code, so most people would see it as a text and won’t even know that it is an attachment. If the malware authors fix it, you will be able to see and open it, thus loading a VBS script in that way. The script will download the virus payload from a malicious domain. Your computer machine gets infected in a matter of seconds, getting your files encrypted. The text of the e-mail message should be the following if it loads correctly:
Hello,
This document has been signed and is now complete.
In the near future you can expect similar e-mails to appear.
Below you can see the new payload domains spreading this version of the ransomware:
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.
Refrain from opening any file from the Internet directly. You should always perform a scan with a security application first.

.Asasin File Virus – Technical Information
The .Asasin File Virus is the newest Locky ransomware variant. The extension .Asasin is placed to all encrypted files. This version of the notorious cryptovirus has been spreading through the Necurs Botnet.
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 have only minor changes, leaving the core of the ransom message intact for the most part and is stored inside two files called “asasin”. Those files are with a .bmp and a .htm extensions. You can preview the image that replaces your Desktop background from down below:
The ransom message reads the following:
!!! 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:

The TOR payment page shows above reveals that the .Asasin file virus demands 0.25 Bitcoin as payment, which equals to 1.200 US dollars at the moment of writing. However, you should NOT under any circumstances pay anything to these cybercriminals. Nobody can guarantee that you will recover your data upon paying, or that you won’t get your files infected again in the near future. Adding to that, giving money to cybercriminals could be interpreted as supporting them financially, and could also motivate them to keep creating more ransomware viruses. Apparently, the latter is true as new variants of Locky ransomware keep showing up.
.Asasin File Virus – Encryption Process
The .Asasin File Virus appends the .Asasin 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 versions:
→.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. A file will be renamed and receive the new extension and its name will be something like 42W8TZ2K-98PW-YG37-U2F2DS8V-KOA3A226UIX1.asasin. The length will always be the same, due to how the cryptovirus has been coded.
The Locky cryptovirus has a high probability to delete the Shadow Volume Copies from the Windows Operating System by executing the following command:
→vssadmin.exe delete shadows /all /Quiet
That command eliminates one of the proper ways for restoring your computer system along with its files to a previous state. If the command is run, the encryption process of the virus will become quite more effective.
