Top Ten Web Hacking Techniques of 2009 (Official)

Every year the Web security community produces dozens of new hacking techniques documented in white papers, blog posts, magazine articles, mailing list emails, etc. Not to be confused with individual vulnerability instances brandishing CVE numbers, nor intrusions / incidents, but actual new methods of Web attack. Some techniques target websites, others Web browsers, and the rest somewhere in between. Historically much of this research would unfortunately end up in obscure corners of the Web and become long forgotten. Now it its fourth year the Top Ten Web Hacking Techniques list provides a centralized repository for this knowledge and recognize researchers contributing to the advancement of our industry. 2009 produced ~80 new attack techniques (see below).

The diversity, volume, and innovation of the research was impressive. Competition was as fierce as ever and the judges had their work cut out. Rich Mogull, Dinis Cruz, Chris Hoff, HD Moore, Billy Rios, Dan Kaminsky, Romain Gaucher, Steven Christey, Jeff Forristal, and Michal Zalewski were tasked with ranking the field based upon novelty, impact, and overall pervasiveness. For any researcher simply the act of creating something unique enough to appear on the list is itself an achievement. Today the polls are close, votes are in, and the top ten list has been finalized. Researchers making the cut can expect to receive praise amongst their peers and take their place amongst those from previous years (2006, 2007, 2008).

Top honors go to Alexander Sotirov, Marc Stevens, Jacob Appelbaum, Arjen Lenstra, David Molnar, Dag Arne Osvik, Benne de Weger for their work on “Creating a rogue CA certificate.” The judges were convinced by no small margin that this entry stood head and shoulders above the rest. The team will be awarded a free pass to attend the BlackHat USA Briefings 2010! (generously sponsored by Black Hat)

Congratulations to all!

Coming up at IT-Defense (Feb. 3 - 5) and RSA USA 2010 (Mar. 1 - 5) it will be my great honor to introduce each of the top ten during my “2010: A Web Hacking Odyssey” presentations. Each technique will be described in technical detail for how they work, what they can do, who they affect, and how best to defend against them. The opportunity provides a chance to get a closer look at the new attacks that could be used against us in the future.

wait, rogue cert is 2008! chirstmas 2008 at CCC and all the research was done in 2008! And moxie attack is real 2009 and is more useful, usable, people can repeat it and is a new bug. The rogue CA cert is well known md5 coliisions being abused

Nice Top Ten web hacks and the whole list of the hacks!

My congratulation to authors who made the Top Ten.

> Our Favorite XSS Filters and how to Attack them

For somebody they are favorite, for somebody they are not :-). But with no doubts all XSS Filters have holes which can be used to bypass them (and last issue with XSS Filter in IE8 is confirmation to it).

It's interesting note. Wait for what Jeremiah will say about it.

Your arguments is sufficient, but it was better to said it before Top Ten was selected. I heard about both rogue cert and Moxie's works (at the time that you mentioned).

Thanks a lot for links!

Jeremiah Grossman said...

@anonymous, Rouge Cert was "December 30, 2008", and the news really didn't break until into 2009. Either way it wasn't consider for our list before, so we included it... and for good reason obviously.

The bug wasn't found by Mr.Dalili, the original bug has been published here http://www.80sec.com/microsoft-internet-infomation-server-6-isapi-filename-analytic-vulnerabilitie.html few months ago
im sorry for your childish thoughts

cellbloggy said...

Hey.. very nice and useful information. did you mention about PHP injection??? check out my blog for some more hacking?????

El cajon condo said...

Thanks a lot.I have searched many sites.But i got the good idea from your site.Some links are very useful to know something about PHP.. :)
