Thanks for the mention! I helped with the collateral damage exploit (wrote the PE loader).
I didn't ask but Emma -- who wrote the kernel-mode exploit -- and I would probably agree that Collat is not really what we would consider a proper hack of the console since it didn't compromise HostOS. Neither of us really expected game plaintext to be accessible from SRA mode though.
And the plaintext stuff by the way was a great effort by some other folks running https://xboxoneresearch.github.io/
I think it was tuxuser, Torus, and Billy(?) who accomplished that. Hopefully not forgetting anyone critical.
