I agree with @nightxyz. I have some questions about this task. Help me please find the answer: are 32-bit instructions used together with 64-bit ones?
I think there are (as minimum) 2 such instruction: inc edx (0x42) and inc esi (0x46) in function with checking password validation.
Provide please a link to materials on this topic.
junfer001 on 7:08 PM 10/28/2024: I only managed to figure out we need a pasword with 28 characters. still digging for more. i think after the length check, it goes into some hidden XOR code that compares if the pasword is correct. I am too noob to solve the XOR (its only my day 3 in reverse eng). Any tips?
junfer001 on 7:31 PM 10/28/2024: im preety sure the hiden function on 000000000040169B is crashing the program
