marci1175 on 2024-02-11 18:02: Im stuck at the code initalization, i dont get what its doing, my friends are telling me its a struct or a class. And *unknown_class = 4222019i64; could be a hash. Any help is appreciated!

sporta778 on 2024-02-11 18:58: later this is assembler, what about u talking, just u need think. just use debugger, here no hard thing , later. What about talking, what is class. Just using username, i think i can solve it

sporta778 on 2024-02-11 19:00: here just some manipulation with username

sporta778 on 2024-02-13 12:59: Just in debugger press f9 3 times, and u will located at EntryPoint of application.

Clyax on 2024-02-14 16:01: @marci1175 Find the main function, and locate the calculation of the password. As mentioned by @sporta778, its a username manipulation.

sporta778 on 2024-02-16 19:51: Mahesh, look like some social engineering?))

cnathansmith on 2024-02-29 20:28: @Mahesh download and read every book with "Reverse Engineering" in the title cover to cover and then be prepared to put in a lot of hours, research, and frustration working on it. It's very doable in most cases, it's just a lot more complicated.

Phaazes on 2024-04-03 19:38: I found the password generator and realized what it was doing. I had great frustration to find a good debugger where I could see registers value to find out the password ans what was wrong with my method. Otherwise very fun, I learned a lot!
