Posted by Soulskill on from the world-war-three-point-oh dept.

angry tapir writes "A botnet composed of about 50,000 infected computers has been waging a war against US government Web sites and causing headaches for businesses in the US and South Korea. The attack started Saturday, and security experts have credited it with knocking the Federal Trade Commission's (FTC's) web site offline for parts of Monday and Tuesday. Several other government Web sites have also been targeted, including the Department of Transportation."

    Each of these machines has and IP address which it advertises every time it makes an attack. That's right folks: The return IP address is part of the header. You can't route packets without this information.

    Not necessarily. For SYN flood the src address can be spoofed, since the attacker doesn't care if he gets the SYN-ACK.

    What the ISPs could do for this is to filter outbound traffic such that if the src IP is not on their network (i.e., is spoofed) the packet is dropped.
