DNS Attack Writer a Victim of His Own Creation

BobB writes "HD Moore has been owned. Moore, the creator of the popular Metasploit hacking toolkit, has become the victim of a computer attack. It happened on Tuesday morning, when Moore's company, BreakingPoint, had some of its Internet traffic redirected to a fake Google page that was being run by a scammer. According to Moore, the hacker was able to do this by launching what's known as a cache poisoning attack on a DNS server on AT&T's network that was serving the Austin, Texas, area. One of BreakingPoint's servers was forwarding DNS (Domain Name System) traffic to the AT&T server, so when it was compromised, so was HD Moore's company."

      As I understand it, this kind of attack would be noticeable when attempting to use a secure (HTTPS) web connection, because the browser should throw up a certificate error. Is this true?

      Yes, this is true. HTTPS connections require an SSL certificate which must be signed by a Certificate Authority (CA) that your browser trusts. Your browser ships with a database of CA certificates, and you can manually add your own if you want; any SSL cert signed by one of those CAs will be trusted, but any SSL cert signed by anybody else will display a warning message before allowing you to access the web site.

      Unfortunately, there are legitimate HTTPS sites out there using self-signed SSL certificates. Chances are, you've probably seen one at some point, and you went ahead and accepted it anyway, because you figured the company is legitimate and they just skimped on getting an SSL cert signed by a real CA. I know I have. If DNS cache poisoning (or other techniques) can get your browser to think it's talking to a particular host when it really isn't, AND you accept an invalid SSL certificate, you're screwed.

      Note that SSL serves two purposes: it encrypts data while it's being sent over the wire so nobody* can eavesdrop on the connection between your browser and the server, and it also provides authentication so you can be sure that your browser is really talking to the server it thinks it's talking to. Using a self-signed certificate (or a certificate signed by an untrusted CA) renders the second of these useless, but the data is still encrypted.

      * And of course when I said "nobody"... There is a way to intercept SSL connections, but it requires that you install a special CA cert in your browser, which will make your browser trust whoever is intercepting the SSL connections. This makes it possible to set up a caching proxy server that can inspect and cache data being sent over HTTPS. This is crazy stuff you shouldn't think about.

    First some background:

    Flamebait is a message posted to a public Internet discussion group, such as a forum, newsgroup or mailing list, with the intent of provoking an angry response (a "flame") or argument over a topic the troll often has no real interest in.

    An Internet troll, or simply troll in Internet slang, is someone who posts controversial and usually irrelevant or off-topic messages in an online community, such as an online discussion forum or chat room, with the intention of baiting other users into an emotional response[1] or to generally disrupt normal on-topic discussion

    Now what I was originally responding to was:

    If he was an online gamer he would've said this instead:

    "I got pwnd!?!?!!!! FAGS!!! YOU noOBS ALL SUCk!!!111"

    This poster was referring to what Mr. Moore might have said if enjoyed online gaming. Hardly offtopic since he is speculating about Mr. Moore's reaction to events that occured regarding his DNS exploit tool in a situation that could be likened to some sort of upset in online gaming.

    Now my response to this poster:

    Actually my favorite is "jew fucker shitcock".

    I mean seriously.. what does that even mean? If you are going to pwn somebody, or respond to getting pwned, you can at least be witty with your responses. Kids these days make Forest Gump look like Einstein.

    Now this hacker gets HIGH marks for what he did. Performing a DNS exploit on the very creator of a DNS exploit tool is actually very well played and Moore's response was pretty cool too. :)

    In my first line I offered an alternative to the posters hypothetical response for Mr. Moore. It is directly related to my own experience. I clearly indicate that I am not addressing him, and that the use of quotes is a pretty good indication of that. No reasonable person would assume that I intended an angry or emotional response from the poster, or to draw anger from any other posters or readers in this thread.

    Now flamebait is directly related to that poster, while trolling is related to the whole thread and the general audience. I cannot imagine that my alternate response could be construed as intentionally baiting anybody into angry passionate responses, nor was the content of my post offtopic. As of yet, I have not received any angry responses over what I written and the original poster wrote back with a Penny Arcade explanation of the phenomenon.

    I further went on to ask what it actually meant and gave commentary about the lack of sophistication in some of the "banter" going back and forth in online gaming today.

    I ended the post with my opinion of the hacker's exploit and Mr. Moore's response to the whole situation, which was one of amusement.

    Now while I wont be so narcissistic to proclaim my post worthy of attention from all or deserving of a +10, the troll and flamebait moderations actually do a disservice. I regularly meta-moderate and more often that not (80%+) I tend to overturn the troll and flamebait moderations. However, this is usually many months after (6+) after the post has occurred.
