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.

      Problem:
      The other thing Microsoft won't tell you is that if paramilitants do a home invasion, they can take your machine right out of the house and have access to all data and the entire network, for that matter.

      Solution: Install complex home alarm system, man traps, CCTV, and acquire armed guards, string up razor wire and dig tunnel system deep in the jungle.

      Ethic:
      I told microsoft that their computers were totally unprotected from physical theft by armed gangs of paramilitants and received no response. I am now sharing this with the community.

      Several jobs ago, the I did software development. The manager didn't like how every time I found a significant bug I added it to a test library that I kept and ran against every version of the code that I was about to put out to the group. His thought was "the odds of someone making the same mistake twice are non existent". One time he told me to put the code out before it was done the regression tests. Sure enough, crash and burn. And yes, my regression tests later caught the bug. Never again.

      As a further indication that I was right, I put an interface around the public interface of my libraries to validate all the parameters and actions. I noticed some people would make the same error so much that I even personalized some of the error messages. Like: "Your passing a string instead of an address John", and "Your reading from a closed object Kevin".

    It may be a little thing called a firewall. A firewall is a spyware-like little piece of software that constantly pings a special server called a firedoor so that spammers hackers, and their ilk know when your computer is available on the internet. Unfortuntely Microsoft refuses to release a patch for this thing but a piece of software called a backdoor can be used to prevent the firewall from doing its dirty work. Download one today!

    Blanket Attacks (like blaster, where every windows computer on the net with windows sharing on is hit about 6 times an hour) are usually only viable when the Default configuration is insecure.

    At least with SP2 there is some basic security in terms of the firewall being on by default.

  12. What is the LAND attack? by fizbin · · Score: 5, Informative
    Quoting from http://www.insecure.org/sploits/land.ip.DOS.html:
    i recently discovered a bug which freezes win95 boxes. here's how
    it works: send a spoofed packet with the SYN flag set from a host, on an open
    port (such as 113 or 139), setting as source the SAME host and port
    (ie: 10.0.0.1:139 to 10.0.0.1:139). this will cause the win95 machine to lock
    up.
    So it's a way to either remotely lock up or reboot a target machine. I would assume (not having, you know, tried it or anything) that this includes most windows-based webservers.

    A friend showed this to me a few days ago and I was unable to reproduce the attack over the LAN, both with my own code and some code of the original LAND found with google. Both were run from linux by opening a raw socket, filling in ip and tcp headers including checksums using the structs in ip.h and tcp.h, and sending with sendto(). In both cases ethereal would show the packet as recieved but the machine would operate normally.
