Dropping Routine

This Trojan drops the following files:

  • %User Profile%\Local Settings\svchost.exe - detected as BKDR_BLADABIN.UK

(Note: %User Profile% is the current user's profile folder, which is usually C:\Documents and Settings\{user name} on Windows 2000, XP, and Server 2003, or C:\Users\{user name} on Windows Vista and 7.)

It executes the dropped file(s). As a result, malicious routines of the dropped files are exhibited on the affected system.

NOTES:

After performing its malicious routines, this Trojan replaces the original malicious .RTF file with a normal document file and opens it.
