As I thought, this DNAS Certificate when you log in, confirms to the server it's a valid PS3, and IS editable. We could definitely "hot-edit" this packet if we can get a program for it. (Working on mine, but no progress really).
We could replace "*.*.*.dl.playstation.net" with 192.168.0.100 or another IP or server. Without disconnecting the PS3 from the server!
Instant win? I believe so.
This is by far the most obvious exploit no one seemed to catch.
Now that the proof is there (hopefully), this will work if we can edit it.
I.E, Create a server with SSL capabilites to use as a proxy for everyone's PS3, also bypassing firmware updates, etc.
The server will "change" the *.*.*.dl.playstation.net to anything we want.
I'm thinking a site should be made, where a user has a custom Control panel, and can edit the server of their choice. Allowing everyone to be able to redirect their ps3, to a file anywhere.
I'm thinking this would be a great idea for everyone.
Any ideas guys?
