reversing

This crackme is less about actual reverse engineering and more on the programming side. You must have some decent knowledge of computer science and algorithms to solve this.

This is also another easy crackme. I don’t know why is it rated 4.0 in difficulty. It should be like 2 or less than that. All you have to do is read the assembly of the program or decompiled code (if available) and everything will be clear.

You can download the challenge binary from here. This is a keygen like crackme. Program asks you for a key that isn’t directly stored inside the program. You have to reverse the key checking algorithm to genreate key.

Hi folks! My exams ended recently and I started working on my skills again. I’ve been learning cryptography and binary exploitation for past few days but my reversing skills havent improved much since past year.

I’m always having problems solving a VM obfucscation challenge in any CTF. This time I plan to end this by solving a VM CrackMe. I got this from a team-mate ( h4x5p4c3 ), another helpful team-mate.

Background Story So, I started to gain interest in pwn challenges when I saw one of my team-mate (4n0nym4u5) solving a pwn challenge from pwnable.tw. I didn’t understand a bit but there was this urge in me trying to understand what he was doing.

“Arguing that you don’t care about the right to privacy because you have nothing to hide is no different than saying you don’t care about free speech because you have nothing to say.

In this post, I will write about how I solved my very first crackme. Tools you will need are : A Linux terminal This crackme Ghidra If you are on Windows you can use cygwin or some other emulator.
