Sam Bowne: Attacking Web users and servers with SSLstrip and Slowloris[1]

Please RSVP if you're planning to come (see further below).

For our 2010-05-18 BALUG meeting, we're excited to present:

Sam Bowne Instructor, City College San Francisco (CCSF)[2],
Computer Networking and Information Technology Department[3]

Many Websites mix secure and insecure content on the same page, like
Facebook[4].  This makes it possible to steal all the data entered on
such a page easily, using Moxie Marlinspike[5]'s SSLstrip tool.
Sam Bowne will explain and demonstrate this attack.

Slowloris is a very new layer 7[6] denial-of-service attack[7] created
by RSnake[8] 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.  Sam will explain and demonstrate this attack, and
discuss various ways to protect your Apache servers.

Sam will provide 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[9] and Toorcon[10] on
Ethical Hacking, and taught classes and seminars at many other schools
and teaching conferences.

He has a B.S. in Physics from Edinboro University of Pennsylvania[11]
and a Ph.D. in Physics from University of Illinois, Urbana-Champaign[12].
His Industry Certifications are: Certified Ethical Hacker,
Microsoft: MCP[13], MCDST[14], MCTS[15]: Vista; Network+, Security+,
Certified Fiber Optic Technician.

Well, don't worry we won't turn you away, but the RSVPs really help the
Four Seas Restaurant plan the meal and they help ensure that we'll be
able to eat upstairs in the private banquet room.
