Probably all the available guides and 100% factual information we have about how Denuvo work and it's cracking:

And

Discord server of a person who cracked a Football Manager game which had denuvo (Sharing information on Denuvo)

And

EMPRESS usually adds protection that obfuscates the code of her cracks/bypasses, but on December 2019 (I believe while EMPRESS was still a part of CODEX) an unfinished (unstable) crack without the added protection got publicly leaked which lead to Denuvo fixing many of the exploits EMPRESS used in the newer version of Denuvo. Skilled people can use this to be able to look into how some of EMPRESS's code works.

And

Oh yea well also some partially leaked source code for VMProtect that is often used with Denuvo, but I'm sure that VMP is it's own can of worms that an entirely separate rentry can be made for.

This list will be redesigned and have mirrors and backups added to everything later (When I have the time and energy) and if I find anything more I'll add here as well. This rentry is basically W.I.P., but it's functional
(I also own rentry.co/fuckdenuvo , fkdenuvo, fuckdrm and fkdrm)
