Beginner Hint 1: About the Admin Bot

\n\n- In this challenge, an Admin Bot is provided separately from the web application itself.\n- The Admin Bot opens a specified URL in Headless Chrome and leaks the flag in a specific way. Read the code to understand when and how the flag is leaked.\n- You need to host a web page that is accessible to the bot. You can use your own server or existing hosting services, but we have provided RequestBin to make hosting web pages for CTF purposes easier.\n- If you're unfamiliar with how the Admin Bot works, we recommend solving [Fushigi Crawler](https://alpacahack.com/daily/challenges/fushigi-crawler?month=2026-01) and reading its writeup first.\n\n

Beginner Hint 2: About RequestBin

\n\n- RequestBin is a service for easily hosting web pages for CTF purposes.\n- It is a tool to help you solve challenges, not the target server itself.\n- You can find instructions on how to use it [here](https://github.com/alpacahack/requestbin/README.md).\n\n

Beginner Hint1: Admin Bot について

\n\n- この問題では、Webアプリ本体とは別に Admin Bot が用意されています。\n- Admin Bot は指定されたURLを Headless Chrome で開き、特定の方法でフラグを流出させます。どのような場合にどのように流出しているか、コードを読み、確認しましょう。\n- この問題では、Bot からアクセス可能なWebページを公開する必要があります。自前のWebサーバーや、Webページをホストできる既存サービスを使っても良いですが、簡単にCTF用途のWebページをホストできるようにRequestBinというサービスを用意しました。\n- Admin Bot の使い方がまだ曖昧なら、先に [Fushigi Crawler](https://alpacahack.com/daily/challenges/fushigi-crawler?month=2026-01) を解いてWriteupを読むことをおすすめします。\n\n

Beginner Hint2: RequestBin について

\n\n- RequestBin はCTF用途でWebページを簡単にホストするためのサービスです。\n- 特定の問題を解くためのツールであり、攻撃対象のサーバーではありません。\n- 使い方は[こちら](https://github.com/alpacahack/requestbin)にあります。\n\n
