Google releases Skipfish, an open-source web security scanner
It's Michel Zalewski's (known to his friends and those, like me, who fear him as "lcamtuf") code.<p>It's a command-line Unix tool. It builds with almost no exotic deps other than GNU IDN.<p>It's a pure-async wordlist-driven crawler/fuzzer. It is screaming fast on the network I'm testing it on. Because it's async, it's not bottlenecked on demand-threading for each request.<p>It generates pretty HTML reports. Well, pretty for a C program.<p>It's Apache licensed. There are things in here I'd probably steal, like the URL parser; it's much tighter than mine.<p>How useful is this going to be for YC-style apps? Meh? You should definitely run it on your QA instance. Make sure you give it a login cookie to run with. It will find things. But where it looks like Skipfish is <i>really</i> going to do some damage is on the enterprisey J2EE- and .NET-stack apps.
