Technical Details

Sadhound drops a text file in Windows Temp folder and opens it with Notepad. The text looks as follow:

There's no
 special reason
 for sending
 this to you,
 except that...
 I was feeling
 a little lonely,
 and when I asked myself
 what I seemed to be
     missing the most,
     the answer
     turned out to be
 I Miss You

F-Secure Anti-Virus detects Sadhound with the existing updates as a dropper.
