code intergrity check in retail 11.2+

[ostapus]

Anyone can give some info/hints on how code integrity check is done in 11.2+ ? In the past - it was done checking calc crc and cross check with the table. In 11.2 i can't find where or how it is done.
In the past - i could setup HW RW breakpoint somewhere in the code and upon triggering - could see where crc is done in wow code. In 11.2 - my HW breakpoint is not getting triggered. I suspect - the check is done in wow_loader, but can't figure out where/how to start digging in

Afaik they didnt changed it, probably it is decrypted in a new way from eidolon, well depends when you checked it the last time before 11.2

I had success using breakpoints and was able to get around the checks. Im fairly new to reversing retail so i cannot say what changed but the check is indeed in wow_loader.dll. It is obfuscated but looks to me like they dont use crc but another algo.
