SUMIT 2009 followup

This is a follow-up post to my short piece on SUMIT 09, the U-M IT security symposium.

The talk by Moxie Marlinspike was really, really good, and pretty scary. I found a copy of his presentation on the Black Hat site, and while you won't get his commentary by just looking through the deck, you'll definitely come to understand how weak many implementations of SSL are (were?), and how Moxie was able to exploit them. If you have traditionally felt pretty secure when using a web site via SSL, make heavy use of software with automated updates and downloads (like Mozilla), or think you can avoid problems by typing the URL into the address bar v. clicking links on web pages, this will make you reconsider your position.

I also started poking around his web site,, and highly recommend reading some of his stories. I've read all but a few, and most have been pretty interesting. Not at all techie stuff; just good reads.
