[CTF Series #1] Write-up on the reverse engineering challenge.

To get the flag from the binary (ELF) file.

Topics Covered:
1. Radare2, x32/x64 dbg
2. Linux Command (objdump, awk, cut and grep)
3. Python Scripting

Here are the ideas on how to solve this challenge :D. Let’s perform static analysis on the binary file by using radare2 in linux machine (my favourite debugging tools).
