this technique is not new, and is quite commonly used to fool AV engines,
not just Sophos.
( and yes, Morphine works as well as commercial "executable packers")
If I recall, a certain trojan group ( now defunct ) used a simple string
change to change their standard releases to that of undetected versions they
sold ( for up to $300). I realy dont know why this is being reported here.
