Rules

Capture The Flags (CTFs) are competitions that involve many aspects of cyber security: cryptography, steganography, web exploitation, reverse engineering, forensics, and others.

Teams are presented with a set of specific "questions" (i.e.; challenges) across a range of categories.

• The goal of each challenge is to recover a special string of text (letters, numbers, characters), called a flag.

• PECAN+ CTF Flags are in the format pecan{some_text_here}. The whole string, including pecan{ and }, needs to be submitted. Flags are not case sensitive, and they may or may not include pecan{} when you find them. When a flag is in a different format, this will be stated in the challenge description.

• Points clarified: Teams gain points for every solved challenge. Most challenges are worth a maximum of 500 points. Every time a Team solves a challenge, the value of that challenge decreases, down to a minimum of 100 points. This means the value of each challenge is set by how many Teams manage to solve it.

• Don't cheat! Compete ethically! Solve challenges ethically and within your Team only (i.e.; do not seek outside advice or help). You are, however, welcome to use whatever digital tools you have at your disposal.

• There is no limit on incorrect flag submissions. However, attacking the virtual machine and/or the scoring infrastructure is prohibited (i.e.; anything outside the .chals.ecusdf.org subdomain). This includes sending a lot of useless traffic through automated tools (e.g.; dirbuster).

Thanks for reading, here's your flag: pecan{i_play_by_the_rules} If you find a problem, please let us know via Discord so that we can fix it and improve the PECAN+ CTF experience for everyone.
