Published 2016-11-09
Denial of service usually relies on a flood of data. Slow Loris takes a more elegant approach, and almost bores a server to death. Dr Mike Pound explains.

    Express explanation: Imagine sending 100 old grandmas to a convenience store, with all of them trying to tell a story from their childhood to the cashier so that no other customers can buy anything.

    This is now my favorite Denial of Service attack as well

    The first rule of coding: All user input is evil.

    All Mikes videos seem to be so simple to follow and his presentation makes you want to follow.... Where were you when I was at school?

    OMG! a computerphile that actually shows some code! Is it christmas or something?
  • Gooberslot
    It seems weird that he's using the Ubuntu machine for browsing and the Windows machine for serving.
  • NeatNit
    One of my favorite computerphile videos in recent memory!
    Will you cover how servers would defend against this technique?
  • Jelle Verest
    People calling themselves hackers because they did a DDoS attack, is like people calling themselves lock pickers for blowing up the safe.
  • I love these kinds of videos. My favorite one is when tom scott talked about the NTP attack method.
  • cheeeeez
    I’m really amazed by the depth of knowledge that Dr Pound has. He knows everything from SQL injection to DoS to image recognition to neural networks etc
  • Lewis B
    I could listen to Dr Pound explain things for hours. Such an interesting video! Thanks for the upload Computerphile :)

    I love the videos with Dr Pound, he's always so enthusiastic and speaks clearly.
  • Thomas Gourley
    I love Mike's videos explaining how to do these attacks! I would never do them (I don't want to go to jail :) ), but they are really interesting. Keep 'em coming!

    My God, this guy is so freaking amazing.
  • Dr. Mike Pound: writes 67 lines of codes and breakes a site
    Me: writes 5000 lines of codes and my program is still useless.

    I want Mike to explain RUDY as well! The most common DDoS attack methods would be awesome to hear more about. He explains it very nicely!
  • MMQuck
    it would make things so much easier if viruses actually had the .virus extension like at 0:45
  • Rem
    Wow that's such a clever attack.
  • Sebastian Suarez
    I love how excited he is about this DoS and explaining it. The explanation really helped with my studies for CEH! THanks!
