Subject: Microsoft WINS Vulnerability + OS/SP Scanner

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

While replicating, it's possible to guess the OS and SP, in addition
you have the heap base address.
Conclusion: all needed for a skilled hacker to intrude a vulnerable
computer, however a script kiddie wont be able to do something because
each wrong hacking attempts may corrupt the WINS database and so on ,
move where this is needed to overwrite. This is where the skilled
hacker will use the heap base address retrieved while scanning to
start a bruteforce attack , nor at best, to analyze how is moving the
heap :)
For example, the exploit that I have published (v0.3) is doing a small
part of 2k with the corresponding heap base , but you will have to
update it to catch some other heap positions.

I attach the win32 binary, follow class101.org and hat-squad.com if
you are seeking for the source or FreeBSD version, I think I will
share them soon.
