RE: CounterAttack

["Dolbow, Phil" <PDolbow () NetTexas com>]

Andy et al..

Being of military (Infantry) origin I am quite prone to want to take 
the offensive and fire back at a high rate of fire on a system that
is assaulting mine. I don't however do so as then I become one of the
bad guys, and in my opinion, step over the line.

I am interested though what the list members think about this. I would 
like to pose these questions:

If your network is PROBED by another system, where do you draw your line?

A) Log the data and otherwise do nothing.
B) Probe the other system.
C) Infiltrate the other system, but do no damage.
D) Shut the other system down.
E) Destroy the other system.
F) Destroy the other system and all others around it.

If your network is ATTACKED by another system, where do you draw your line?

A) Log the data and otherwise do nothing.
B) Probe the other system.
C) Infiltrate the other system, but do no damage.
D) Shut the other system down.
E) Destroy the other system.
F) Destroy the other system and all others around it.

Thanks for your feedback.

        NetBIOS Scans haven't necessarily increased.  I can't believe that
any port is more sought out than NetBIOS.  I see 139 and 445 more than any
other port, and it has been that way for more than 2 years.  But it isn't
without good reason....if you get probed for 139 or 445, probe back; 8 out
of 10 times it is open, and that system is infected with a worm.  Then hit
'em with a smbclient or Winfingerprint, get that password policy and
username/share list, find the weak password and welcome to their
network......or dcom.c, that works too.

when it strikes, it won't be silent.
