PS Vita Release: PSID_Dumper
In the light of the recent Vitamin leak, developer Smoke decided to release PSID_Dumper, a simple proof of concept that reminds developers how they can, to some extent, protect some of their beta releases by preventing them from running outside of the beta tester’s console.
This technique was used at some point in the PSP scene to prevent leaks of upcoming custom firmwares and kernel exploits.
Of course, I have no doubt that TheFloW and other members of Team FreeK knew they could have done this for Vitamin too, but chose not to.
Nevertheless, you might find this release interesting if you want to play with it. The source ships with a sample on how one could “protect” their homebrew. Keep in mind that unless you obfuscate the code, it could be reasonably easy for some people to update the binary and replace it with their own PSID. This is not a silver bullet to avoid leaks.
