he Xbox 360 security system is designed around a hypervisor concept and you know how Unprivileged code interacts with the hypervisor syscalls
if you dont know what a syscall is it basically calling the system and telling it what to do
Now if we make a payload to patch the syscall
we can change what it does so by doing that we can change what the hypervisor does and allow us to write to areas were not suppose to get it
it not possible to directly overwrite even non priviledged code,
but we could trick it if we called the sycall with
anonhacker privlage code
Priviledged code: //might be possible to right to hypervisor
13D8: cmplwi %r0, 0x61
13DC: bge illegal_syscall
...
13F0: rldicr %r1, %r0, 2, 61
13F4: lwz %r4, syscall_table(%r1)
13F8: mtlr %r4
it might be possible
