More on Flash hacking

A quick follow-up to my previous post on testing Flash sites: Stefano Di Paola recently delivered a superbly comprehensive presentation on Flash application security during this year's OWASP conference in Milan. It goes into great detail on the ActionScript security model, how Flash applications are sandboxed, and a variety of client-side attack vectors. The resulting exploits include classic cross-site scripting issues, as well as a variation known as cross-site "flashing". Stefano also covers a few concepts for more advanced hacks, and plans to release testing tools and additional whitepapers soon. You can check out his web-log at Wisec.it.
