“unhackable” is a bit sensationalized here. the Xbox One is actually a security success story not because it is impossible to hack, but because it’s a rare example of a console that wasn’t hacked in its service lifetime. at the risk of giving praise to Microsoft, the architecture is actually really neat and informed the security features of subsequent Windows releases, ie a hypervisor with sandboxed sub containers (this is why they required TPMs).
(also i’m not agreeing with requiring a TPM for general purpose machines; they make sense on a bespoke hardware platform like a game console)
i bet this hack is nuts, but the blue team deserves some level of kudos
