Aircrack-ng チートシート
## 概要
Aircrack-ngは、WiFiネットワークの監査とワイヤレスセキュリティ実装のテストを目的とした、包括的なワイヤレスネットワークセキュリティ評価ツールスイートです。元々は元のAircrackプロジェクトのフォークとして開発され、Aircrack-ngはワイヤレスペネトレーションテストとセキュリティ研究の事実上の標準となっています。このスイートには、パケットキャプチャと注入から暗号化キーの復元とアクセスポイントの操作まで、完全なワイヤレスネットワーク評価機能を提供する複数の専門ツールが含まれています。
Aircrack-ngスイートは、いくつかのコアコンポーネントで構成されています：ワイヤレスパケットキャプチャとネットワーク検出のためのairodump-ng、パケット注入と攻撃実装のためのaireplay-ng、WEPおよびWPA/WPA2キーの復元のためのaircrack-ng、ワイヤレスインターフェースの管理とモニターモード設定のためのairmon-ng。追加のツールには、キャプチャしたパケットの復号化のためのairdecap-ng、カスタムパケット作成のためのpacketforge-ng、偽のアクセスポイント作成のためのairbase-ngがあります。このモジュラーアプローチにより、セキュリティ専門家は特定の要件に基づいて、ターゲットを絞った評価とテスト方法のカスタマイズが可能です。
このフレームワークは、統計分析によるWEPクラッキング、WPA/WPA2ハンドシェイクキャプチャと辞書攻撃、WPS PINアタック、ネットワークの耐性をテストするための各種注入攻撃など、幅広いワイヤレスセキュリティプロトコルと攻撃ベクトルをサポートしています。Aircrack-ngは、脆弱な暗号化実装の特定、アクセスポイント設定のテスト、ワイヤレスセキュリティポリシーの検証に特に有用です。活発な開発コミュニティと広範なドキュメンテーションにより、Aircrack-ngはワイヤレスセキュリティ専門家、ペネトレーションテスター、ワイヤレスインフラストラクチャのセキュリティ確保を担当するネットワーク管理者にとって不可欠なツールであり続けています。

Common Issues
Monitor Mode Issues:
# Check if interface supports monitor mode
iw list|grep -A 10 "Supported interface modes"
# Kill interfering processes
sudo airmon-ng check kill
# Manually set monitor mode
sudo ip link set wlan0 down
sudo iw dev wlan0 set type monitor
sudo ip link set wlan0 up
# Check monitor mode status
iwconfig wlan0No Networks Detected:
# Check interface status
iwconfig
sudo iw dev
# Verify monitor mode
iwconfig wlan0mon|grep Mode
# Check for hardware issues
dmesg|grep -i wifi
lsusb|grep -i wireless
# Try different channels
sudo iwconfig wlan0mon channel 1
sudo iwconfig wlan0mon channel 6
sudo iwconfig wlan0mon channel 11Injection Issues:
# Test injection capability
sudo aireplay-ng --test wlan0mon
# Check for packet injection support
sudo aireplay-ng --test wlan1mon
# Verify driver support
lsmod|grep -i wireless
dmesg|grep -i driverパフォーマンス最適化
Aircrack-ngのパフォーマンス最適化:
# Use multiple CPU cores for cracking
aircrack-ng -p 4 capture.cap
# Optimize airodump-ng
sudo airodump-ng --band abg wlan0mon # Scan all bands
sudo airodump-ng -M wlan0mon # Enable manufacturer lookup
# Use faster wordlists
# Create optimized wordlist
sort wordlist.txt|uniq > optimized_wordlist.txt
# Use GPU acceleration with hashcat
aircrack-ng -J hashcat_format capture.cap
hashcat -m 2500 -w 3 hashcat_format.hccapx wordlist.txtセキュリティ上の考慮事項
倫理的な使用
法的考慮事項:
- 自分が所有または明示的な許可を得たネットワークのみをテストする
- 無線セキュリティテストに関する地域の法律を理解する
- 評価を実施する前に適切な承認を得る
- コンプライアンスのためにすべてのテスト活動を文書化する
- キャプチャされたデータのプライバシーと機密性を尊重する
運用セキュリティ:
- 可能な限り隔離されたテスト環境でAircrack-ngを使用する
- キャプチャされたデータに対して適切なアクセス制御を実装する
- 機密情報の安全な保存と送信
- Aircrack-ngと依存関係の定期的な更新
- 無線侵入検知システムによる検出を監視する
データ保護
キャプチャされたデータのセキュリティ:
- キャプチャされたハンドシェイクとトラフィックを暗号化する
- 一時ファイルの安全な削除を実装する
- データ送信に安全なチャネルを使用する
- データ保持ポリシーを実装する
- テストインフラストラクチャの定期的なセキュリティ評価
