Find which AS3 classes are included in a SWF

Question

I have been investigating swfmill and ran it against some of my AS3 SWFs, I get

<UnknownTag id="0x52">
    <data>...</data>
  </UnknownTag>

and

UnknownTag id="0x4C">
    <data>...</data>
  </UnknownTag>

These lines are most likely contain the data I am looking for, but the data is unreadable. Does anyone know of another way to find the included classes in a SWF, or know how to decipher the data in these tags? Any help would be greatly appreciated.

Answer 1

AFAIK swfmill predates AVM2, so I wouldn't expect much luck doing anything with code on an AVM2 swf using swfmill.

EDIT: Perhaps Sothink Swf Decompiler would be better suited to your needs?
