I’ve been in Vegas for what seems like forever attending Blackhat & Defcon. I’m completely worn out even though I’ve been going to bed sober and before midnight for the past two nights. Raging ’til four for a couple nights really does that to you.
Getting back to the point, it really looks like a lot of security folks love Python. There were a number of talks focusing on Python specifically and I didn’t notice any of them pointing out vulnerabilities in the language. In the talk on Offensive Python for Web Hackers, the presenters demonstrated a number of cool tools [Edit (August 2, 2010): like pywebfuzz] for testing web apps for vulnerabilities.
However, I’ve been unable to find one of the tools — pywebfuzz — on google code where the presenter said it would be. Rich Smith’s talk on Reversing Python Bytecode was pretty interesting. Basically, it looks like companies selling closed source software by distributing .pyc files and doing some obfuscation aren’t doing enough.
Other talks of note were Jackpotting ATMs and Marco Slaviero’s Lifting the Fog (of memcached). If you have a memcached server that is not firewalled, fix it ASAP. That was one of the scariest and most interesting briefings.
