What is a CTF?

- Capture the Flag is a hacking competition within a controlled, safe environment. CTFs typically are made up of individual challenges that, when solved, reveal a secret key or "flag" that can be submitted to score points. They can be offensive, defensive, or both. Most CTFs last a day or two in length, however it us not unheard of for there to be long-term CTFs.

How do I get good at CTFs?

- By practicing. These links have some good resources on practice CTFs. I'd also recommend some googling and finding old write ups and some continuous CTFs that go on.

Will we be competing in CTFs this year?

- Yes. See the calendar for specific dates. The two we'll be doing this semester are CSAW and hack.lu
