For past few days I’ve been working on a personal program/binary analysis tool which I’m calling Katana. I’ve made a simple Elf file loader for now but for it to have more utilities while working, and for me to learn something more, I’ve started working on my own disassembler for Katana.

Writeup and solution files can be found here. For only writeup, go here.

One day, a Student came to his Master asked: Student : Why do I have to keep learning like this? We live at the bottom of these hills and you make me climb a different one everyday.

I’ve been struggling with reverse engineering rustlang binaries for a while in CTF challenges. So I’m starting a reverse engineering series where I reverse engineer several rustlang binariesa and try to understand how they actually work.

You can get the challenge binary from here. This is another awesome challenge from crackmes.one. The binary is able to run properly in specific builds of Windows 10.

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.
