PicoCTF — Collaborative Development, Commitment Issues, Specialer

Collaborative Development

Author: Jeffery John
Description
My team has been working very hard on new features for our flag printing program! I wonder how they’ll work together? You can download the challenge files here:

challenge.zip

At first, unzip the file using the command : unzip challenge.zip

We can see that there are a lot of commits :

Now, we’ll try to merge all the commits into the file and see what happens.

Merging all the commits gave us the flag : picoCTF{t3@mw0rk_m@k3s_th3_dr3@m_w0rk_2c91ca76}

Commitment Issues

Description
I accidentally wrote the flag down. Good thing I deleted it! You download the challenge files here:

challenge.zip

First, I unzipped the file using the command : unzip challenge.zip

We need to know basics of git to get this flag.
Simply re-intialize the git rep by using the command : git init
Then checkout to the Commit where the Flag was created and then when we is it the message, we are able to see the flag i.e. picoCTF{s@n1t1z3_ea83ff2a}

Specialer

Author: LT ‘syreal’ Jones, et al.
Description
Reception of Special has been cool to say the least. That’s why we made an exclusive version of Special, called Secure Comprehensive Interface for Affecting Linux Empirically Rad, or just ‘Specialer’. With Specialer, we really tried to remove the distractions from using a shell. Yes, we took out spell checker because of everybody’s complaining. But we think you will be excited about our new, reduced feature set for keeping you focused on what needs it the most. Please start an instance to test your very own copy of Specialer.

Additional details will be available after launching your challenge instance.

ssh -p 59025 ctf-player@saturn.picoctf.net. The password is 3f39b042

I tried to use different commands but only echo was working so I started to search a way to print the output of the files present in the directory.

The flag is : picoCTF{y0u_d0n7_4ppr3c1473_wh47_w3r3_d01ng_h3r3_811ae7e9}
