I already posted this on a xbox360/ps3 board but nobody answered there (my nick there for anybody who cares: Morgentaler )
So here we go:
I was just browsing through my game data folder to see how much space each item was using, and I accidentally clicked X as I passed over the Stuntman: Ignition game data.
Much to my surprise it actually tried to *execute* it as an application, even playing the chime and showing the PS3 logo. It did this both with a disc (GTA4) and without a disc in the drive. None of the other game data did this when selected.
After the chime and the logo the screen goes dark so I don't know what else it might be doing.
I should note my firmware: 2.35
Possible exploit? (If I'm far behind the curve on this one, forgive me)
