PicoCTF2018 – Reverse Engineering – reversing warmup 1

Objective:

Throughout your journey you will have to run many programs. Can you navigate to /problems/reversing-warmup-1_1_b416a2d0694c871d8728d8268d84ac5c on the shell server and run this program [1]  to retreive the flag?

Hints:

1) If you are searching online, it might be worth finding how to exeucte a program in command line.

Solution:

So this is a warmup so it is super simple

I just connected up to the shell, cd’d to the problem folder

pico-2018-shell:/problems/reversing-warmup-1_1_b416a2d0694c871d8728d8268d84ac5c$ ls

run

so there is program in there called run

. @pico-2018-shell:/problems/reversing-warmup-1_1_b416a2d0694c871d8728d8268d84ac5c$ ./run

picoCTF{welc0m3_t0_r3VeRs1nG}

there is the flag
