Core Function: BruteShark is a Network Forensic Analysis Tool (NFAT) designed to process network traffic captures (PCAP files) or live traffic to extract sensitive information, reconstruct sessions, and map network activity.

Primary Use-Cases:

- Passive Credential Harvesting: Extracting usernames, passwords, and hashes from captured network traffic for protocols like FTP, Telnet, HTTP, and more.

- Network Infrastructure Mapping: Visualizing network nodes and communication patterns based on observed traffic.

- Incident Response Data Triage: Quickly processing large volumes of network captures to identify key artifacts like transferred files, DNS lookups, and VoIP calls.

- Security Posture Assessment: Identifying weak or cleartext protocols in use on a network to recommend security upgrades.

- Offline Attack Preparation: Extracting password hashes from authentication exchanges and converting them to formats suitable for offline cracking with tools like Hashcat.

Penetration Testing Phase: BruteShark is primarily used in the Post-Exploitation phase after network access has been established and traffic can be sniffed. It can also be used for Passive Information Gathering if an analyst has access to pre-existing traffic captures.

Brief History: BruteShark was created to provide security researchers and network administrators with a comprehensive and easy-to-use tool for deep network traffic inspection. It consolidates multiple analysis tasks—from credential extraction to network mapping—into a single, powerful command-line interface, streamlining the forensic analysis workflow.

#### Strategic Campaigns: Advanced Command Chains

BruteShark's output is designed to be machine-readable, making it perfect for integration into larger analysis pipelines using standard Linux utilities.

#### Objective: Find All Credentials for a Specific User

This chain uses BruteShark to extract all credentials and then pipes the CSV output to `grep` to filter for a specific username.

Command:

Bash

    brutesharkcli -i network_dump.pcap -m Credentials && cat ./BruteShark-Results/*/Credentials.csv | grep "admin"

Command Breakdown:

- `brutesharkcli ...`: First, runs BruteShark to generate the `Credentials.csv` file.

- `&&`: Ensures the second command only runs if the first one succeeds.

- `cat ./BruteShark-Results/*/Credentials.csv`: Reads the content of the newly created credentials file. The wildcard `*` handles the timestamped directory name.

- `|`: A pipe that sends the output of the `cat` command to the input of the next command.

- `grep "admin"`: Filters the input, printing only lines that contain the string "admin".

Ethical Context & Use-Case: After identifying a potentially compromised user account named "admin," an analyst needs to determine the full extent of the exposure. This command chain quickly sifts through all captured credential data to find every instance where that specific username was used, helping to identify all affected services on the authorized test network.

--> Expected Output:

#### Objective: Identify Most Frequent DNS Lookups

This workflow extracts DNS data, isolates the domain names using `awk`, and then counts the frequency of each lookup to find the most contacted domains.

Command:

Bash

    brutesharkcli -i dns_heavy.pcap -m DNS && cat ./BruteShark-Results/*/DNS.csv | awk -F, 'NR>1 {print $4}' | sort | uniq -c | sort -nr | head -n 5

Command Breakdown:

- `brutesharkcli ... && cat ...`: Runs BruteShark and outputs the resulting `DNS.csv` file.

- `awk -F, 'NR>1 {print $4}'`: A powerful text processor. `-F,` sets the delimiter to a comma. `NR>1` skips the header row. `{print $4}` prints only the fourth column (QueryName).

- `sort`: Sorts the list of domain names alphabetically, which is required for `uniq`.

- `uniq -c`: Collapses adjacent identical lines and prepends a count of how many times they occurred.

- `sort -nr`: Sorts the counted list numerically (`-n`) and in reverse order (`-r`) to bring the highest counts to the top.

- `head -n 5`: Displays only the top 5 lines of the sorted output.

Ethical Context & Use-Case: In a threat hunting scenario on a corporate network you're monitoring, identifying the most frequently accessed domains can reveal important patterns. It can highlight command-and-control (C2) beaconing, identify reliance on specific third-party cloud services, or uncover misconfigured devices making excessive DNS requests.

#### Objective: Isolate High-Traffic Client IPs from the Network Map

This chain generates a network map, extracts the source IP addresses, and counts them to find the "chattiest" clients on the network.

Command:

Bash

    brutesharkcli -i full_day_capture.pcap -m NetworkMap && cat ./BruteShark-Results/*/NetworkMap.csv | awk -F, 'NR>1 {print $1}' | sort | uniq -c | sort -nr | head -n 10

Command Breakdown:

- `brutesharkcli ... && cat ...`: Generates and displays the `NetworkMap.csv`.

- `awk -F, 'NR>1 {print $1}'`: Skips the header and prints only the first column (SourceIP).

- `sort | uniq -c | sort -nr | head -n 10`: The same counting and sorting technique as the previous example, this time showing the top 10 source IPs by connection count.

Ethical Context & Use-Case: When performing a network baseline analysis for a client, identifying the hosts that generate the most connections is key. These could be critical servers, but they could also be misconfigured machines or hosts infected with malware that is scanning the network. This command provides a quick way to identify hosts that warrant further investigation.

#### AI Augmentation: Integrating with Artificial Intelligence

BruteShark's structured output is ideal for programmatic analysis. By using Python with data science libraries, we can uncover insights that are not immediately obvious from the raw data.

#### Objective: Analyze Password Complexity and Reuse with Pandas

This example uses a Python script with the Pandas library to ingest BruteShark's `Credentials.csv` file and perform a sophisticated analysis of password habits.

Code (`analyze_creds.py`):

Python

    import pandas as pd
    import sys

    def analyze_password_strength(password):
        length = len(password)
        has_upper = any(c.isupper() for c in password)
        has_lower = any(c.islower() for c in password)
        has_digit = any(c.isdigit() for c in password)
        has_special = not password.isalnum()

        score = 0
        if length >= 8: score += 1
        if has_upper: score += 1
        if has_lower: score += 1
        if has_digit: score += 1
        if has_special: score += 1

        if score == 5: return "Strong"
        if score >= 3: return "Medium"
        return "Weak"

    if len(sys.argv) < 2:
        print("Usage: python analyze_creds.py <path_to_credentials.csv>")
        sys.exit(1)

    cred_file = sys.argv[1]
    try:
        df = pd.read_csv(cred_file)

        # Analyze password reuse
        password_counts = df['Password'].value_counts()
        reused_passwords = password_counts[password_counts > 1]

        # Analyze password complexity
        df['Complexity'] = df['Password'].astype(str).apply(analyze_password_strength)
        complexity_distribution = df['Complexity'].value_counts()

        print("--- Password Reuse Analysis ---")
        print(reused_passwords)
        print("\n--- Password Complexity Distribution ---")
        print(complexity_distribution)

    except FileNotFoundError:
        print(f"Error: File not found at {cred_file}")

Command Breakdown:

- `python analyze_creds.py <path>`: Executes the Python script.

- `<path>`: The full path to the `Credentials.csv` file generated by BruteShark.

Ethical Context & Use-Case: After extracting credentials during an authorized audit, simply listing them is not enough. This AI-augmented approach provides powerful, data-driven insights for a final report. You can quantify the risk by showing exactly how many passwords are "Weak," how many are reused across different services, and which specific passwords pose the greatest threat if compromised. This elevates the analysis from simple data collection to actionable security intelligence.

--> Expected Output:

    --- Password Reuse Analysis ---
    password123    5
    123456         3
    admin          2
    Name: Password, dtype: int64

    --- Password Complexity Distribution ---
    Weak      10
    Medium     4
    Strong     2
    Name: Complexity, dtype: int64

#### Objective: Visualize the Network Map with NetworkX and Matplotlib

This script parses the `NetworkMap.csv` and uses powerful Python libraries to create a more detailed and customizable graph visualization than the default PNG.

Code (`visualize_map.py`):

Python

    import pandas as pd
    import networkx as nx
    import matplotlib.pyplot as plt
    import sys

    if len(sys.argv) < 2:
        print("Usage: python visualize_map.py <path_to_networkmap.csv>")
        sys.exit(1)

    map_file = sys.argv[1]
    try:
        df = pd.read_csv(map_file)

        G = nx.from_pandas_edgelist(df, 'SourceIP', 'DestinationIP')

        plt.figure(figsize=(15, 15))
        pos = nx.spring_layout(G, k=0.15, iterations=20)

        # Identify high-degree nodes (potential servers)
        degrees = [val for (node, val) in G.degree()]
        node_colors = ['red' if deg > 10 else 'skyblue' for deg in degrees]

        nx.draw(G, pos, with_labels=True, node_size=200, node_color=node_colors, font_size=8, width=0.5)
        plt.title("Network Communication Graph (Highlighted Hubs)")
        plt.savefig("advanced_network_map.png")
        print("Advanced network map saved to advanced_network_map.png")

    except FileNotFoundError:
        print(f"Error: File not found at {map_file}")

Command Breakdown:

- `python visualize_map.py <path>`: Executes the visualization script.

- `<path>`: The full path to the `NetworkMap.csv` file from BruteShark.

Ethical Context & Use-Case: While BruteShark provides a basic network map, a security analyst often needs more control over the visualization to highlight specific findings. This script allows you to programmatically identify and color-code "hub" nodes (those with many connections), making it instantly clear which devices are the most critical communication points in the network. This advanced visualization is far more impactful in a final report to a client than a standard diagram.

--> Expected Output:

    Advanced network map saved to advanced_network_map.png
    [VISUAL OUTPUT: A PNG file named 'advanced_network_map.png' is created. It shows a spring-layout graph where nodes with more than 10 connections are colored red, and all other nodes are sky blue, visually distinguishing servers or key hosts from clients.]
