Hijacking Web 2.0 Sites with SSLstrip and Slowloris

When: Tue October 13, 2009 07:30 PM to 09:30 PM

Speaker: Sam Bowne

Location: O'Reilly Media

Many Websites mix secure and insecure content on the same page, like Facebook. This makes it possible to steal all the data entered on such a page easily, using Moxie Marlinspike’s SSLstrip tool. I will explain and demonstrate this attack.

Slowloris is a very new layer 7 denial-of-service attack created by RSnake that stops Apache web servers completely with very low bandwidth—one packet every 2 seconds. The Apache developers were notified of this vulnerability and decided it was unimportant and not worth patching. I will explain and demonstrate this attack, and discuss various ways to protect your Apache servers.

I will hand out complete instructions so that anyone can easily set up both these attacks on their own machines.

Sam Bowne has been teaching computer networking and security classes at CCSF since 2000. He has given talks at DEFCON and Toorcon on Ethical Hacking, and taught classes and seminars at many other schools and teaching conferences.

NBLUG Elections and “Where’d my Files Go? A guide to the Modern Ubuntu Distribution”

When: Tue November 11, 2008 07:30 PM to 09:00 PM

Speaker: Kyle Rankin

Location: O'Reilly Media

While you might not be able to tell at a cursory glance, a lot has changed behind the scenes on a modern Ubuntu system from what you might be used to if you have used Linux for years. For example, did you know Ubuntu is phasing out System V init? That you can’t loopback-mount the initrd? In this talk I would discuss the current changes Ubuntu is making to what we might consider the traditional Linux system. There’s a little something for everyone on the talk: For Linux newbies who are curious about what’s under the hood I will cover the traditional and modern boot process including how init works and follow up with a guide to where important files are in Ubuntu. For the experienced Linux user I’ll show you how (and why) things have changed and where you can look now when you want to, for instance, change the default runlevel on an Ubuntu system.
