ESETCrackme2015
Hi all!
I have a question about some data from this task. When I reversed this crackme, I found in the module that is injected data block that is not referenced. these blocks consist of printable characters. example: Code:

I tried hard this crackme, but I figure out that I need to study more to solve it. I passed by the first part, downloaded the second file and I couldn't understand how it was injected on memory and how to start get the the passwords.
Although many sites has a solution explained I'm not feel well to only copy it and don't understand inside all tasks. So, what do you thinks that I need focus on study to be able to understand and solve this crackme? My goal isn't only solve this, but feeling that I know what do and improve my skills with it. Thanks in advance guys! []'s |
