We HypeBoy topped Plaid CTF 2024! 👑 @_Reinose_en @justlikebono @munsiwoo @real_as3617 @mhibio_ptw @howdays1 @stanzz @soo_sudo @n1net4il @1nteger_c @c2w2m2 @pr0cf51 @cmy981224 @csapp3e ironore15 G0RiYa Thanks to the great support from dakuo & hellsonic

@lolzareverser @ShuntIsReal @rajxnull @offsectraining @jinmo123 @c2w2m2 Yes, getting a job is very important, but it's not everything. Why do CTF? In the past, I did ctf just for fun. nowadays, it's for personal growth.

@lolzareverser @ShuntIsReal @rajxnull @offsectraining @jinmo123 @c2w2m2 Is getting a job is everything? To correct one thing, I did not complete the BoB program. I started CTF in my early teens. It's far from thinking about having a job. Many hackers around me aren't doing CTF just because of money or jobs.

@soo_sudo @ShuntIsReal @rajxnull @offsectraining @jinmo123 @c2w2m2 Great, thats why Korea players are ahead in CTF and have the best players because your companies require ctf/bounty/CVE , here in middle-east OSCP is widely required. congrats for building the strognest capabilities by the BoB (best of the best) program.

@lolzareverser @ShuntIsReal @rajxnull @offsectraining @jinmo123 @c2w2m2 So I never really resonated with the idea that OSCP is overrated, but after reading your post, I can see why ppl would say that. In fact, @c2w2m2 and I used to work at the same company (neither of us had a certification like OSCP) and we worked full-time even while in college.

@lolzareverser @ShuntIsReal @rajxnull @offsectraining @jinmo123 @c2w2m2 Do you really think so? When hiring offensive security researchers in Korea, the biggest criteria is CTF / bugbounty / CVE achievements. Except for a few large corporations and accounting firms, OSCP is not required.

데프콘 본선을 4위로 마무리했습니다. 14명의 한국인이 모여 만든 낭만은 내년에도 계속됩니다. 😆 HypeBoy got 4th place in #DEFCON 🥳 Keep your eyes on 14 koreans :))) youtu.be/11cta61wi0g

I'm uncertain about being an organizer next year. But if i do, I'll ensure to engage with the teams involved prior to making any public announcements

However, unlike that case, what I was overlooked in this case is that it may not be "obvious cheating". It is certain that to be disqualified by the rules, but there may be a "victim" to it.

2 years ago, a similar anti-cheating mechanism was applied in a domestic CTF. (of course, unlike codegate, there were many challenges for beginners and there were limit of team size (<=4)), and a total of 22 teams were caught cheating on 6 challenges. (obvious cheating)

FYI : The total prize money for the final round has been increased. totally 86 million KRW (approx. $65,000 worth)

Codegate CTF 2023 Preliminary is coming. 🚀🚀🚀🚀🚀🚀 Here are the details: Duration: 2023.06.17 10:00 - 2023.06.18 10:00 (UTC+9) Official website: codegate2023.org Discord: discord.gg/8GdTSKshHm
