Security researchers strongly advise users to look for any .xtbl extensions on their files and in case they detect them to try and remove the threat. One way to do this is to follow the step-by-step instructions after this article and check the hotlinks for suggested methods for decrypting the encrypted files. Experts strongly advise against complying with the ransom demands of the cyber crooks.

Trojan.Ransomcrypt.T – How Did I Get Infected?

One way to become a victim of this malicious threat is by opening spam mail that may contain ‘Open this.’ type of infected files. Some spam mails may resemble reputable services such as the Windows 10 Upgrade e-mail and most users with little or no experience with spam mail may fall for it. Some emails have even fooled experienced users this is why email software with spam filters is always recommended.

Trojan.Ransomcrypt.T In Detail

Symantec researchers have established that the .T variant is more sophisticated than the main one. Once the malicious file has been executed on the user PC, the Trojan then creates these objects:

→Windir\csrss.exe
Temp\lock
Temp\state
UserProfile\Application Data\}randomname{.bmp

It also tampers with the registry editor, creating the following registry entries:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run\”Client Server Runtime Subsystem” = “%Windir%\csrss.exe”
It aims to make the file “csrss.exe” run on system startup.

After modifying several user settings, the trojan horse then opens up an active connection to these reported http locations:

→gxyvmhc55s4fss2q.onion/reg
gxyvmhc55s4fss2q.onion/prog
gxyvmhc55s4fss2q.onion/err
gxyvmhc55s4fss2q.onion/cmd
gxyvmhc55s4fss2q.onion/sys

After this is done, the trojan then begins scanning for files on external memory carries like removable drives and remote drives. It also scans fixed drives used by the PC. This trojan supports a huge database of file formats it encrypts:

→.3ds .3fr .3g2 .3gp .7z .accda .accdb .accdc .accde .accdt .accdw .adb .adp .ai .ai3 .ai4 .ai5 .ai6 .ai7 .ai8 .anim .arw .as .asa .asc .ascx .asm .asmx .asp .aspx .asr .asx .avi .avs .backup .bak .bay .bd .bin .bmp .bz2 .c .cdr .cer .cf .cfc .cfm .cfml .cfu .chm .cin .class .clx .config .cpp .cr2 .crt .crw .cs .css .csv .cub .dae .dat .db .dbf .dbx .dc3 .dcm .dcr .der .dib .dic .dif .divx .djvu .dng .doc .docm .docx .dot .dotm .dotx .dpx .dqy .dsn .dt .dtd .dwg .dwt .dx .dxf .edml .efd .elf .emf .emz .epf .eps .epsf .epsp .erf .exr .f4v .fido .flm .flv .frm .fxg .geo .gif .grs .gz .h .hdr .hpp .hta .htc .htm .html .icb .ics .iff .inc .indd .ini .iqy .j2c .j2k .java .jp2 .jpc .jpe .jpeg .jpf .jpg .jpx .js .jsf .json .jsp .kdc .kmz .kwm .lasso .lbi .lgf .lgp .log .m1v .m4a .m4v .max .md .mda .mdb .mde .mdf .mdw .mef .mft .mfw .mht .mhtml .mka .mkidx .mkv .mos .mov .mp3 .mp4 .mpeg .mpg .mpv .mrw .msg .mxl .myd .myi .nef .nrw .obj .odb .odc .odm .odp .ods .oft .one .onepkg .onetoc2 .opt .oqy .orf .p12 .p7b .p7c .pam .pbm .pct .pcx .pdd .pdf .pdp .pef .pem .pff .pfm .pfx .pgm .php .php3 .php4 .php5 .phtml .pict .pl .pls .pm .png .pnm .pot .potm .potx .ppa .ppam .ppm .pps .ppsm .ppt .pptm .pptx .prn .ps .psb .psd .pst .ptx .pub .pwm .pxr .py .qt .r3d .raf .rar .raw .rdf .rgbe .rle .rqy .rss .rtf .rw2 .rwl .safe .sct .sdpx .shtm .shtml .slk .sln .sql .sr2 .srf .srw .ssi .st .stm .svg .svgz .swf .tab .tar .tbb .tbi .tbk .tdi .tga .thmx .tif .tiff .tld .torrent .tpl .txt .u3d .udl .uxdc .vb .vbs .vcs .vda .vdr .vdw .vdx .vrp .vsd .vss .vst .vsw .vsx .vtm .vtml .vtx .wb2 .wav .wbm .wbmp .wim .wmf .wml .wmv .wpd .wps .x3f .xl .xla .xlam .xlk .xlm .xls .xlsb .xlsm .xlsx .xlt .xltm .xltx .xlw .xml .xps .xsd .xsf .xsl .xslt .xsn .xtp .xtp2 .xyze .xz .zip

After scanning this huge variety of files the trojan variant then encrypts them with a .xtbl extension. An encrypted file may look similar to this one:

→New Word Document.docx.xtbl

And Windows displays a notification message that the file is corrupt upon opening it.
After encrypting the files, this ransomware virus then leaves the following files in the folders of the encrypted files
The Trojan then drops the following file in each folder that has encrypted files like this example:

→C:\Users\[USERNAME]\Documents\Readme124816248912.txt

After doing so, the next step of the trojan is to change the desktop wallpaper to a picture containing demands that ask the user to open the readme text with the random number above for more information. The readme text contains the following message in Russian and English:

“ATTENTION! All the important files on your disks were encrypted. The details can be found in the README.txt files which you can locate on any of your disks.”
