    We are halfway through CTF. I'm sure most people did not own the core stack of an embedded OS, yet. I prepared an opportunity for you to change just that. You got another 24h to grab a sweet first blood flag. Find the challenge here: Gogo! :-)

    Andy has a great point about the CTF community here. It's one of the most inclusive and welcoming communities I know. No need for ethical policing. What. So. Ever.

    The stolen flags and the warning to a CTF team that their banner could be destroyed by some idiots make me sad. These people have *no* idea what the CTF community is like. I learned the CTF community doesn't give a flying fuck where are you from or how you look.

    I really enjoyed . At the end it was a very tight race which could have ended with different teams on top. All in all a deserved win by LC↯BC. Also thanks to , and of our on-site team and the other people we met for an amazing time!

    During 2days esoteric and arduous pwning, players have showed formidable gifts through the delicate exploits of them. Finally, LC↯BC() win the triumph of Real World CTF 2018 Finals. Congratulations! Thanks for every CTFer!
