Windows 2003 and XP SP2 Vulnerable To LAND Attack
An anonymous reader writes "Dejan Levaja, a Serbian security engineer has discovered that nearly 8 years after the attack was first made public, WIndows 2003 and Windows XP SP2 are in fact vulnerable to the historic LAND attack." Granted, you need to have the firewall turned off for this work, but there's a whole lotta machines that don't have it turned on.
Not trying to be an M$ apologist, but who will really be vulnerable to this? Home (l)users will most likely have the firewall on (because it is on by default) and any sane IT dept. will have a hardware firewall guarding any internet facing windows boxen. If you haven't firewalled your boxen in this day and age, you pretty much get what you deserve.
