FormulaOne: protocol reverse engineering and network client exploitation. Official page intentionally gives almost no level 0 detail. Public material mostly repeats the official description, so this cannot be completed from writeups alone.

The intended first task appears to be source discovery: source code for the first level is accessible by logging into another wargame on the same server, and figuring out which one is part of the challenge.

Live reconnaissance checklist:

1

# after getting any valid account on the same OTW host
find / -path '*formulaone*' -o -path '*/formulaone0*' 2>/dev/null
find / -type f -readable -name '*formula*' 2>/dev/null
ls -la /formulaone /formulaone/* 2>/dev/null

If source is found, write the section in this order:

  1. Identify where the source leaked from and why it is readable.
  2. Extract protocol constants, message framing, checksums and state transitions.
  3. Build a Python socket client with explicit timeout/retry handling.
  4. Verify against the live service and only then add the spoiler.

Tools: pwntools, Python sockets, nc/socat, tshark, mitmproxy.

Live verification note: 本次环境里的远程登录/exploit 被拒绝，无法现场枚举同服务器目录；未验证前不写 spoiler。

当前发布状态：entry reconnaissance mapped, unsolved。这篇不是完整 writeup；保留它的目的只是记录入口假设和后续调查方法。
