Process activity
The Trojan creates the following process(es):
%original file name%.exe:1932
The Trojan injects its code into the following process(es):
csc.exe:344
Mutexes
The following mutexes were created/opened:
No objects were found.
File activity
The process %original file name%.exe:1932 makes changes in the file system.
The Trojan creates and/or writes to the following file(s):
%Documents and Settings%\%current user%\Application Data\KEWTpM.exe (70216 bytes)
%System%\drivers\etc\hosts (410 bytes)
%Documents and Settings%\%current user%\Application Data\KqJuyYy.exe (70216 bytes)
