After reading through all the pages I decided I would dig a little (especially since I just ordered an Archos 101 IT and was interested)
Below is my first pass at getting some source, I'm sure it's not complete but I didn't have time to validate my results
Notes: Shows exploit method but not contents of su or ls
Notes: Contents of su?
I figured I would use a service like pastebin instead of pasting the >5000 lines of code
Update: Confirming what others have posted in this thread, ls is clearly obfuscated, will look at it more later
Obfuscating code (in this application) is typically used to hide malicious activity or to delay the manufacture from patching
