IERAE CTF 2026- FINAL for Humans Round 1にの参加ありがとうございました！がっつりAIに破壊されたけど、一般的にアクセス可能なモデルではなかなか解けなかったんじゃないでしょうか。（スクロール幅を使った新しいXS-Leakで、知識がないと難しいはず。） gist.github.com/tyage/bdeb53…

IERAE CTF 2026: FINAL for Humans #1 starts in just 12 hours! One challenging Web problem. 8 hours. $1,000 in prizes. We believe AI can't solve this one on its own. Can you prove us wrong, or crack it by teaming up with AI? alpacahack.com/ctfs/ierae-fi…

I made this week's AlpacaHack B-side challenge. It's the first challenge I've written since AI got strong. Sadly it's not solved yet. Mythos, Fable, anyone?🥺 alpacahack.com/daily-bside/c…
