This trojan is hosted on the website http://www.cad-portal.com/includes/[...].php and executes automatically when the user visits the website. This trojan downloads a another trojan onto the system. The downloaded trojan steals the user's internet banking information and is detected as Trojan-Spy.Banbra.RM.

Execution

Upon execution, the trojan creates the file:

  • %temp%\bloloolol86.txt

This text file contains the text 'olha'.The trojan then downloads and execute the binary files:

  • %windir%\system32\innit226.exe
  • %windir%\system32\msnmsgsr.exe

To distract the user from detecting any malicious activity, the trojan also download innocuous-looking files from:

  • http://www.paeksan.com/technote/001.jpg
  • http://www.paeksan.com/technote/002.jpg

The first JPEG file, 001.jpg, will be renamed tomsnmsgsr.exe;the second JPEG file, 002.jpg, will be renamed toinnit226.exe. Both are renamed using Windows command prompt and stored on %windir%\system32.
