The bookmarklet uses JavaScript to add Flash players to any MP3 links on a web page in the exact same way the regular version of 1 Bit does. The difference is that these players are applied in your browser manually, allowing you to use 1 Bit wherever you like.
Yesterday, I received a post in the Pen-Test mailing list requesting for tips/resources on penetration testing of flash applications.  While there are some tools and white papers available, I could not find many authoritative resources which wraps the entire spectrum of flash security testing of RIA applications. So here is an endeavor to detail out the steps of testing.  I will keep this post only to outline the essential steps or points.  Please feel free to recommend additional inclusion of tools and techniques.  The idea is to come up with a comprehensive paper which can be used by pen-testers to test flash based Rich Internet Applications (RIA).
