What is CTF?
CTF (Capture The Flag) is a cybersecurity competition that challenges participants to solve a
variety of tasks ranging from finding coordinates based on a photo to hacking your way into a
server to steal data.
LIT CTF is a Jeopardy style contest: we provide a list of challenges that award points to teams that
solve them. There are several categories of CTF challenges:
- Cryptography (crypto): Decrypt mysterious messages with both classical and modern algorithms.
- Pwn: Exploit a binary by causing buffer overflow and memory leaks, i.e. manipulating undefined behaviors to bypass their normal functionality
- Reverse Engineering (rev): Reverse Engineer files and binaries to find corresponding flag
- Web: Exploit a website to obtain the flag.
- Miscellaneous (misc): Everything else, including forensics, extracting the flag from various file formats (e.g. images, audio)
