New Denial-of-Service Attack Is a Killer

Posted by kdawson on from the fighting-a-resource-war-with-an-unfair-advantage dept.

ancientribe writes "Hacker RSnake blogs about a newly discovered and deadly denial-of-service attack that could well be the next big threat to the Internet as a whole. It goes after a broadband Internet connection and KOs machines on the other end such that they stay offline even after the attack is over. It spans various systems, too: the pair of Swedish researchers who found it have already contacted firewall, operating system, and Web-enabled device vendors whose products are vulnerable to this attack." Listen to the interview (MP3) — English starts a few minutes in — and you might find yourself convinced that we have a problem. The researchers claim that they have been able to take down every system with a TCP/IP stack that they have attempted; and they know of no fix or workaround.

      No, it's my fault. I linked to slashdot from slashdot, slashdotting slashdot. So slashdot's slashdotted.

      Sorry.

    Doesn't affect me. I haven't used DOS in YEARS. Some folks need to move up to Windows 3.1. That is where it is at.

      Uhh, you know that's still based on DOS right? You should update to Windows 95 like me to be safe.

      Nope, NT 3.1 circa '93. We were an early adopter on a currently top of the line Pentium (1)--50 MHz, I believe. Thing would BSOD if you more than looked at it funny.

    Ignore the story, there's very little chance that a single virus can take down all systems, especially if the user is not running Windows.

    I for instance have multiple rock solid software and hardware firewalls, and most ports blocked - I'd like to see it try taking dow

    Apparently, I should panic:

    cat: /proc/sys/net/ipv4/tcp_syncookies: No such file or directory
    # echo 0 > /proc/sys/net/ipv4/tcp_syncookies
    bash: /proc/sys/net/ipv4/tcp_syncookies: No such file or directory

    I CAN'T TURN IT OFF!

    $ gunzip -c /proc/config.gz | grep -i syn.*cook
    # CONFIG_SYN_COOKIES is not set
