A curated archive of Capture The Flag (CTF) competition challenges organized by event and year, with links to writeups and CTFtime event pages. It covers many well-known CTFs such as 0CTF, spanning multiple years of challenge files.

Use cases

• practice ctf challenges from past competitions
• find writeups for old ctf events
• download pwn and reverse engineering challenge binaries
• prepare for a capture the flag competition
• study past ctf cryptography and web challenges
• build a local ctf practice environment

When to choose

• you want historical CTF challenge files for practice or research
• you need writeup links for specific CTF events and years
• you are training a team or learning security skills through CTFs

When to avoid

• you need a CTF hosting platform to run your own event
• you want guided tutorials rather than raw challenge archives
• you need a vulnerability scanner or offensive security tool
