# Warm up### Category: Reverse### 27 Points### 283 Solves### Problem description:### Must-Have Pre-Workout Warm up Challenge.### Author: Chaocipher### Date: 5/2/2018### Thanks goes to ASIS for organizing the CTF.## StartI downloaded the file from the description. It’s just a 7z file nested inside another 7z file with one file inside: warmup{see screenshot at URL above}
## WarmupThis is just a .c file with a bit of code put into a single line to read.{see screenshot at URL above}
I tinkered with the code a bit, but I didn’t see anything wrong so I just tried to compile it. With enough effort I was able to get the correct GCC compile command with all the required imports. Here is the string I ended up with:#### gcc warmup.c -o warmup.exe -include stdint.h -include stdio.h -include math.h
From there I just ran the exe and waited for a couple minutes.{see screenshot at URL above}### ASIS{hi_all_w31c0m3_to_ASISCTF}
