Taming Conficker, the Easy Way

Dan Kaminsky writes "We may not know what the Conficker authors have in store for us on April 1st, but I doubt many network administrators want to find out. Maybe they don't have to: I've been working with the Honeynet Project'sTillmann Werner and Felix Leder, who have been digging into Conficker's profile on the network. What we've found is pretty cool: Conficker actually changes what Windows looks like on the network, and this change can be detected remotely, anonymously, and very, very quickly. You can literally ask a server if it's infected with Conficker, and it will give you an honest answer. Tillmann and Felix have their own proof of concept scanner, and with the help of Securosis' Rich Mogull and the multivendor Conficker Working Group, enterprise-class scanners should already be out from Tenable (Nessus), McAfee/Foundstone, nmap, ncircle, and Qualys. We figured this out on Friday, and got code put together for Monday. It's been one heck of a weekend."

    If you have even half-assed antivirus in a corporate environment, you'll be able to log into the admin console, and see what machines are infected.
    You can also see when a machine was last in contact with the controller, so if a virus kills the A/V on a machine, it will stop contacting. Anything that's been over a week since contact automatically should be physically investigated.

    Of course, you could be using Norton Internet Security 2009 on your corporate machines, which doesn't have this capability. But if you are, you're an incompetent moron, and shouldn't be trusted with a Gameboy, forget a multi-computer corporate network.

  25. Re:But not in Germany or UK? by smallfries · · Score: 3, Funny

    Ok so you did read it. And I'll assume that you are aware of what you wrote the first time. And I'll assume that you read my response. The only possible logical conclusions are either a) you don't know the different between possession and distribution (thanks blueg3), or b) you are an idiot. I'm not as generous as blueg3, I think you lack the intellectual faculties to post on slashdot. It's a low bar, but by god you've hit it.

    I'm going to try though, and see if you could understand with a little coaching, and help with the big words. You claimed:

    But isn't possession of "hacker tools" such as nmap legally questionable in the UK and Germany?

    Quite straightforward. If we ignore the claim about Germany, which may be correct, you have explicitly claimed that possession of "hacker tools" can be dodgy under uk law. You've reinforced this claim with:

    So if you use nmap to clean your network, you may be open to criminal charges.

    Note, this is identical to the first claim - that possession of "hack tools" is legally iffy in the uk. As this this claim is wrong, and it's explained to be wrong in the links that you provided, I have pointed out to you:

    The prosecution have to show that you intended to use the tool to commit a crime - possession is not enough.

    Ok, you claimed possession is legally iffy. I've explained that it is not, according to your own sources. Now, here is where you failed the slashdot iq test:

    According to the linked article, if you distribute a "hacker tool" that somebody else then uses for an illegal purpose, you're on the hook under UK law.

    A completely different claim. So it doesn't back up your original claim - this is an interesting property of brand new claims that you would do well to memorise. As it is generally understood by a small partially retarded child that you can't win an argument by insisting that something completely irrelevant is true - I would beg you to seek the help of an older bigger child to read your posts before you submit them. And when necessary, to be the one responsible for battering you with the clue stick until you understand.
