# CTF 综合解题编排器
## Phase 1: 解题流程
### 1.1 侦察
```bash
file * # 识别文件类型
strings binary | grep -i flag # 快速字符串搜索
xxd binary | head -20 # Hex 头部
binwalk -e firmware.bin # 提取嵌入文件
checksec --file=binary # 检查保护
nc host port # 连接远程服务
```
### 1.2 分类与 Skill 调度
**按文件类型:**
| 文件类型 | 分类 | 调度 Skill |
|----------|------|-----------|
| .pcap/.evtx/.raw/.dd | 取证 | ctf-forensics |
| ELF/PE + 远程服务 | Pwn | ctf-pwn |
| ELF/PE/APK/.pyc/WASM | 逆向 | ctf-reverse |
| .py/.sage + 数字 | 密码学 | ctf-crypto |
| Web URL/HTML/JS/PHP | Web | ctf-web-methodology |
| 图片/音频/PDF(无明显内容) | 隐写取证 | ctf-forensics |
**按关键词:**
| 关键词 | 分类 |
|--------|------|
| overflow/ROP/shellcode/heap | ctf-pwn |
| RSA/AES/cipher/lattice/LWE | ctf-crypto |
| XSS/SQLi/JWT/SSRF | ctf-web-methodology |
| disk image/memory dump/registry | ctf-forensics |
| find/locate/identify/who/where | ctf-osint |
| obfuscated/C2/malware/beacon | ctf-malware |
| jail/sandbox/encoding/game | ctf-misc |
### 1.3 卡住时转向
1. **重新分类** — 很多题跨分类(Web+Crypto, Forensics+Crypto, Reverse+Pwn)
2. **检查遗漏** — 隐藏文件、备用端口、响应头、注释、元数据
3. **简化** — 检查是否有更简单路径(默认凭据、已知CVE、逻辑漏洞)
**常见跨分类模式:**
- 取证 + 密码学:PCAP/磁盘中的加密数据
- Web + 逆向:WASM 或混淆 JS
- Web + 密码学:JWT 伪造、自定义签名
- 逆向 + Pwn:先逆向再利用
- OSINT + 隐写:社交媒体 Unicode 同形字
## Phase 2: 辅助信息
### 2.1 Flag 格式
常见:`flag{...}` / `CTF{...}` / 自定义前缀(`ENO{...}` / `HTB{...}`)
```bash
grep -rniE '(flag|ctf|eno|htb|pico)\{' .
strings output.bin | grep -iE '\{.*\}'
```
### 2.2 卡住时策略
- 回退侦察:robots.txt、.git、备份文件、目录扫描
### 2.3 文件类型识别
- SQLite 数据库文件:用 sqlite3 命令打开,.tables 查询表结构
