    I've rewrote my Javascript fuzzer to include more options, this one allows you to choose events, html attributes and various quote options. If you have any suggestions or attributes/events you would like me to include then please leave a comment. The fuzzer also now has the branding of my site that I recently redesigned.

    Update...

    I've updated my fuzzer again, it now includes a load of new options including javascript execution from within style tags and randomisation of the javascript: call.

    Check it out here:- JS Fuzzer version 2
