Holiday E-Commerce DDoS Attack Hits EC2 Cloud 75

ARos writes "A holiday DDoS attack targeted a west-coast DNS provider, which is known for serving large-scale E-Commerce sites (including amazon.com and walmart.com). 'Neustar, which provides DNS services to high profile website addresses under the UltraDNS brand, said the flood of malicious traffic, just two days before Christmas, was directed at the company's facilities in San Jose and Palo Alto, and that the effects were mostly limited to California users.' CNet adds: 'In addition to the high-profile sites, dozens of smaller sites that rely upon Amazon for Web-hosting services were also taken down by the attack. Amazon's S3 and EC2 services were affected by the problems, according to Jeff Barr, Amazon's lead Web Evangelist, who retweeted a report to that effect without clarification and confirmed it in later tweets.'"

      Step 1. DOS existing DNS server
      Step 2. Make rogue DNS server active, which returns URL's for phishing organization's transparent proxy.

        What? Do you understand how DNS works? How the fuck would you get root and other recursive DNS servers to connect to your server instead of the real one by merely bringing the real dns servers down? If the attackers would be able to intercept DNS traffic, it wouldn't matter if the real servers we're down or not. But that's a little bit harder to pull off than some kiddie dossing.

      Ever heard of DNS cache poisoning? There really should be an investigation into this. One of the attack vectors is pretty simple - use a DDOS to slow down the response time of the real DNS servers of *.amazon.com, use a cache poisoning timing-based attack on some subset of DNS servers further down the chain (like for example at a medium-sized ISP) to replace the IP of Amazon servers with an IP of your specially prepared hijacking servers, a client goes to amazon.com, but get redirected to your server, you proxy their traffic (use a man-in-the-middle attack to defeat SSL or just use human-engineering for that) until they make a purchase and instead of proxing their credit-card info you just keep it for your self and transfer money to your accounts. Profit!

      Something like that could have taken place here, but you cann't know that until you analyse logs at Amazon and all the ISP DNS servers that could have beenaffected by this.

      Online gambling sites are constantly attacked by DDoS, because they have money, and their continued revenue relies on people being able to connect reliably to their servers. Thus, you can threaten to shut down a site or ask they pay $5000 or so to a

    One reason for DDoS attacks is to prove that you can shutdown a site.

    The site will pay for protection from future attacks. The offshore gambling sites have been "victims" of these attacks according to Steve Gibson.

    • by bartwol ( 117819 )

      But the only protection you can buy from them is their "commitment" to not attack again. That doesn't protect you from another attacker launching an attack, and if you're one who pays, then I'd say you've improved your chance of that.

      It seems that a technical defense is your only real defense, and "paid protection" is the resort of tomorrow's road kill.

            That's not a sentence. I have no idea what you want to convey.

            A "protection racket" is a form of extortion that has existed for thousands of years, if you include feudal states as large-scale "protection rackets."

            It may seem self-defeating to acquiesce to the extortion, but the costs are minimal compared to serious disruption of the business that a DDoS attack from a botnet.

              Thanks for explaining that.

              Do you think the traditional protection racket, as your chosen model, is sufficiently congruent to this case as to make a good argument for a website operator to pay a DoS attacker to not attack again?

              Let me re-phrase my question. Would YOU pay a [purported] DoS attacker to not attack again? (I need to differentiate here between that which you think a smart person such as yourself should do, as opposed to what you think is appropriate for the many stupid people such as myself.)

              • by grolaw ( 670747 )

                The past has shown that the off shore gambling sites have paid repeatedly - and they remain profitable. The protection racket is a parasite that loses when it kills its host.

                    Assuming that I ran an Amazon - a lawful business - I'd report the extortion and work with INTERPOL and the FBI to make the payment and keep my business alive and catch the botnet operator(s).

                    That would, undoubtedly, cost a lot of money.

                      The anonymity of these attackers makes any countermeasure expensive.
