DDoS attack against abuse.ch

The webserver which is hosting abuse.ch and ZeuS Tracker is currently under high system load due to a ongoing DDoS attack against the blog (abuse.ch). The DDoS has started yesterday 02:00 pm (UTC):


The origin seems to be the same as last time (see previous post “DDoS Angriff & Joe Job gegen abuse.ch (german)”). Fact is, that the bots are using the same user agents as during the attack last year:

  • FAST-WebCrawler/3.8 (atw-crawler at fast dot no; http://i.love.teh.cock/support/crawler.asp)
  • Mozilla/5.0 (Slurp/cat; vaginamook@inktomi.com; http://www.supercocklol.com/slurp.html
  • Mozilla/4.0 compatible ZyBorg/1.0 (wn.zyborg@looksmart.net; http://www.lolyousuck.com)
  • Googlebot/2.1 (+http://www.googlebawt.com/bot.html)
  • If we google the user agent above we will find some interesting information about the origin of the DDoS attack:

    “Let’s take a look at yet another bot originating from the Mother Russia. It’s called Illusion, and it has a nice and clear GUI tool for configuration that even an idiot (you could argue that only idiots use malware anyway) can use.”

    Currently it seems that the DDoS mitigation was successfull so that abuse.ch is now up and running again (but unfortunately with a high response time because the DDoS attack still goes on). Let’s see what happens in the next few hour/days.

    Stay tuned.
