Re: Locate address spoofer?

[creining () packetfu org]

If you suspect a spoofer, one quick test to confirm/deny is to use the
utility despoof by Simple Nomad (http://razor.bindview.com/tools). You
can compare the TTL logged with a packet with the TTL you receive from
despoof.  If an attacker is spoofing a packet, the TTL in that packet
will not be the correct TTL of one created _at_ that address (unless
they are really paranoid and tweak the TTL).

Believe it or not routes do change, so this tool is best utilized asap.
