injection-attacker

injection-attacker is an agent for Claude Code from morodomi/redteam-skills. It costs 32 tokens per session (1,362 once invoked), scanned A, original, MIT.

A static code-analysis agent that looks for SQL injection and command injection risks in application code. SQL injection manipulates database queries, while command injection can cause unintended operating-system commands to run.

In plain words
What is it for?
It helps inspect Laravel, Django, Flask, and Express code for unsafe query construction, direct command execution, shell calls, and subprocess calls, while showing safer patterns.
Why use it?
Unsafe input handling can let attackers alter database queries or execute commands. The agent flags code patterns associated with these risks and recognizes several common frameworks.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

injection-attacker scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Expected in a hook, worth knowing in a rule or an instructions file.

Injection Attacker

SQL/Command Injection脆弱性を静的解析で検出するエージェント。

Detection Targets

SQL Injection

Type Description Pattern
Union-based UNION SELECT攻撃 文字列結合でのSQL構築
Error-based エラーメッセージ利用 未処理の例外、エラー出力
Boolean-blind 条件分岐による推測 動的WHERE句構築

Command Injection

Type Description Pattern
Direct execution OSコマンド直接実行 exec(), system()への入力連結
Shell invocation シェル経由実行 shell_exec(), popen()への入力
Subprocess サブプロセス実行 subprocess.call(), child_process.exec()

Framework Detection Patterns

Framework Vulnerable Pattern Safe Pattern
Laravel DB::raw($input), whereRaw($input) DB::table()->where(), Eloquent ORM
Django cursor.execute(f"...{input}") cursor.execute("...%s", [input])
Flask db.execute(f"...{input}") db.execute("...?", (input,))
Express query("SELECT..."+input) query("SELECT...?", [input])

Dangerous Patterns

SQL Injection

patterns:
  # PHP/Laravel
  - 'DB::raw\s*\('
  - 'whereRaw\s*\('
  - '\$.*->query\s*\('
  - 'mysql_query\s*\('

  # Python/Django/Flask
  - 'execute\s*\(\s*f["\']'
  - 'execute\s*\(\s*["\'].*%'
  - 'cursor\.execute\s*\([^,]+\)'

  # Node.js/Express
  - 'query\s*\(\s*[`"\'].*\+'
  - 'query\s*\(\s*`.*\$\{'

Command Injection

patterns:
  # PHP
  - 'exec\s*\(\s*\$'
  - 'shell_exec\s*\('
  - 'system\s*\(\s*\$'
  - 'passthru\s*\('
  - 'popen\s*\('
  - 'proc_open\s*\('
  - '`.*\$.*`'

  # Python
  - 'os\.system\s*\('
  - 'subprocess\.call\s*\('
  - 'subprocess\.Popen\s*\('
  - 'os\.popen\s*\('

  # Node.js
  - 'child_process\.exec\s*\('
  - 'child_process\.spawn\s*\('
  - 'execSync\s*\('

  # Go
  - 'exec\.Command\s*\('

Safe Patterns

以下のパターンは誤検知を避けるため除外:

safe_patterns:
  # PHP - フレームワーク標準
  - 'Artisan::call'
  - 'Process::run'  # Symfony Process

  # Python - 固定コマンド
  - 'subprocess\.call\s*\(\s*\['  # リスト形式(安全)
  - 'subprocess\.run\s*\(\s*\['

  # Node.js - 固定コマンド
  - 'execSync\s*\(\s*["\'][^$]'  # 変数なし
