The person who hacked the original Xbox wrote a book on the topic, which they've since made free: https://bunniefoo.com/nostarch/HackingTheXbox_Free.pdf

TF are you on about? The xbox one of 2013(competitor of the PS4 who got hacked long before) had a ~46% market share in the US and ~35% globally. Hardly insignificant. And any Microsoft Product, even those with much lower market share, attracts significant attention from hackers since it's worth a lot in street-cred, plus the case of reusing cheap consoles as general PCs for compute since HW used to be subsidized. And of course for piracy, game preservation and homebrew reasons.

I again tap the sign of my previous comment, of uring people to stop jumping the gun to talk out of their ass, without knowing and considering the full context.
