In the perspective of digging deeper into the pubkey patch approach I would like to share few very useful information for those that intend to spend time on it.
Find attached the Generic pubkey replacer made by Tanker (win + linux). I tested the Win version on a couple of targets (v11.10 and v11.9.1) and it identifies the pubkey correctly (I double checked in the vendorcode struct in memory), however, I didn't manage to produce a working license, yet (work in progress as I may be missing something crucial in the generation).
Also I would like to recommend the follwing discussion which is quite informative IMHO:

What am missing: reverse the obsucation algorithm used to store the pubkey in the client binary (any help is appreciated: CrackZ may be have something to say about
) (note: not the one the scramble it in memory).
Anyone who would like to join the challenge is more than welcome of course. Feel free to test the Pubkey Replacer and feed back with success/unsuccess stories.
Enjoy !
