Re: Analysis of "stacheldraht"

The source code for "stacheldraht" was published on Packet Storm this
week:
        http://packetstorm.securify.com/distributed

Below are the differences (which affect packet signatures and
some minimal strings in the binary images) between the code that I
analyzed and the current 4.0 release. (Hmm.  Jumping from 1.1 to 4.0
because of #define changes.  Sounds like random works for Microsoft or
Sun! ;)

I will be updating the default values in the "dds" (and "gag") scanners
as soon as possible to use these new defaults, and will add command
line options to "dds" to switch them.  (I didn't do this earlier due to
time constraints.)  Anyone who is doing packet level checks should be
aware of these changed defaults (and that they can easily be changed
further, so be aware of false negative results.)
