I am currently trying to crack a crackme.exe. Before the jump, it compares the following (0 == not registered):

cmp byte ptr ds:[eax+0x15FC], 0x0

If I normally load the .exe and try to go to the address which was eax + 0x15FC, it obviously won't find it. But if I let it run until it comes to the compare, it will find the address in the dump with a value of 0.

So now to my question: How am I able to break when the address gets used or something writes to it?

I already tried setting a Hardware Breakpoint to eax + 0x15FC which did not get triggered.

BTW my goal is to find the location where eax + 0x15FC gets set to 0.

Thanks in advance for the answers!
