There are two different schools of thought:

1) It’s OK to do just about anything to win a CTF, including installing malware on the organisers computers months before the actual event so you’ll have an easy time stealing the flags.

2) It’s not ok to try and win the CTF with a solution the authors did not intend.

Recently the #2 crowd has been winning because the hacking scene has turned corporate and boring. People started to partake in CTFs in the hopes of landing a job(!)

CTFs are indeed ruined for those people, I personally don’t mind.

For the people in group #1 LLMs change little. Attacking the challenges directly was always a last resort.
