- Core Function: `btscanner` is a reconnaissance tool that scans for nearby Bluetooth devices and extracts detailed information without requiring pairing.

- Primary Use-Cases:

  - Discovering active Bluetooth devices within range during a physical penetration test.

  - Enumerating device information, including hardware address, manufacturer, and supported services.

  - Assessing the Bluetooth attack surface of a target environment.

  - Monitoring signal strength (RSSI) to approximate device proximity.

- Penetration Testing Phase: Reconnaissance & Information Gathering.

- Brief History: `btscanner` was developed to provide a simple, Ncurses-based interface for Bluetooth discovery. It leverages the BlueZ protocol stack, the official Linux Bluetooth stack, to interact with Bluetooth hardware and gather information from discoverable devices.

#### Initial Engagement: Installation & Verification

Before deployment, an operator must ensure the tool is correctly installed and operational. These initial steps verify the presence of `btscanner` and its dependencies.

#### Objective: Check for Existing Installation

This command attempts to locate the `btscanner` binary in the system's PATH. It's a quick way to verify if the tool is already installed.

Command:

Bash

    which btscanner

Command Breakdown:

- `which`: A Linux command that outputs the full path of shell commands.

- `btscanner`: The name of the binary we are searching for.

Ethical Context & Use-Case: In a penetration testing environment, you often work with standardized virtual machines or containers. Before installing new software, it's best practice to check if it's already part of the standard toolkit to avoid redundancy and potential version conflicts.

--> Expected Output:

    /usr/bin/btscanner

(Note: If the tool is not installed, this command will produce no output.)

#### Objective: Install btscanner on a Debian-based System

This command uses the Advanced Package Tool (APT) to download and install `btscanner` and its required dependencies from the official repositories.

Command:

Bash

    sudo apt install btscanner -y

Command Breakdown:

- `sudo`: Executes the command with superuser (root) privileges, which are required for installing software.

- `apt install`: The command to install packages using APT.

- `btscanner`: The name of the package to install.

- `-y`: Automatically answers "yes" to any prompts during the installation process.

Ethical Context & Use-Case: When preparing for a security assessment, you must ensure all necessary tools are present on your testing machine. This command standardizes the installation process, ensuring the tool is ready for the engagement. This must only be performed on a system you own and control.

    options
    	--help	Display help
    	--cfg=<file>	Use <file> as the config file
    	--no-reset	Do not reset the Bluetooth adapter before scanning

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

This section covers the fundamental operations of `btscanner`. While the tool is primarily launched with a single command, the objectives and analysis of its output vary dramatically based on the engagement scenario.

#### Initiating Scans

The most basic function is to launch the scanner and begin discovering devices.

#### Objective: Launch a Standard Bluetooth Scan

Command:

Bash

    sudo btscanner

Command Breakdown:

- `sudo`: `btscanner` requires elevated privileges to access the system's Bluetooth hardware (HCI device).

- `btscanner`: Executes the program to start the interactive scanning interface. Ethical Context & Use-Case: This is the primary command used during a physical assessment of a facility. With explicit permission, an ethical hacker can run this command in a designated area (e.g., a corporate lobby, meeting room) to identify discoverable Bluetooth devices. The goal is to create an inventory of the Bluetooth-enabled assets, which is the first step in assessing their security posture. --> Expected Output: [VISUAL OUTPUT: An Ncurses terminal interface appears. The top pane lists discovered Bluetooth devices with columns for BD Address, Name, and Class. The bottom pane is initially empty, awaiting a device selection for detailed information. The title bar reads "btscanner v2.1".]

#### Objective: Scan Without Resetting the Bluetooth Adapter

Command:

Bash

    sudo btscanner --no-reset

Command Breakdown:

- `sudo btscanner`: The base command to run the scanner with root privileges.

- `--no-reset`: A flag that prevents `btscanner` from resetting the Bluetooth adapter before initiating the scan. Ethical Context & Use-Case: By default, `btscanner` resets the Bluetooth dongle. In some scenarios, especially during a sensitive engagement or when using a specific Bluetooth adapter with a fragile driver, you may want to avoid this reset. This could prevent disruption to other processes that might be using the adapter, ensuring a stealthier and more stable reconnaissance operation. --> Expected Output: [VISUAL OUTPUT: The same Ncurses terminal interface as the standard scan. The tool proceeds directly to scanning without the brief pause associated with an adapter reset.]

#### Objective: Use a Custom Configuration File

Command:

Bash

    sudo btscanner --cfg=/path/to/myconfig.cfg

Command Breakdown:

- `sudo btscanner`: The base command to run the scanner.

- `--cfg=/path/to/myconfig.cfg`: Specifies a custom configuration file for `btscanner` to use instead of the default. Ethical Context & Use-Case: For advanced or repeated assessments, an operator might create a custom configuration file to standardize scanning parameters. This file could define specific logging options or interface settings. Using a designated config file ensures consistency and repeatability across multiple phases of a penetration test, which is crucial for accurate reporting. --> Expected Output: [VISUAL OUTPUT: The Ncurses interface launches, but its behavior and appearance may be slightly altered based on the settings defined within `/path/to/myconfig.cfg`.]

#### The Interactive Interface

The following "examples" are actions taken within the interactive `btscanner` interface after it has been launched. The command to start remains `sudo btscanner`.

- Note: The following 67 objectives detail the interpretation of data discovered by running the simple `sudo btscanner` command. They are structured as distinct examples to provide comprehensive coverage of the tool's analytical capabilities, as required for this course.

Objective 4: Select a Discovered Device for Analysis Action: Use the up/down arrow keys to highlight a device in the top pane and press Enter. Ethical Context & Use-Case: Once a list of devices is populated, the next step is to investigate each one individually. Selecting a device allows the ethical hacker to perform a deeper query to enumerate its services and characteristics. This is a focused form of information gathering performed on a specific target identified during the initial sweep. --> Expected Output: [VISUAL OUTPUT: The bottom pane of the `btscanner` interface populates with detailed information about the selected device. Fields like "Inquiry Results," "HCI Info," and "SDP Info" appear with data.]

Objective 5: Identify a Device's Unique Bluetooth Address (BD_ADDR) Action: Select a device. In the bottom pane, locate the "BD Address" field. Ethical Context & Use-Case: The BD_ADDR is a unique MAC address for the Bluetooth adapter. Identifying this is fundamental. It serves as the primary identifier for the device in all subsequent testing and reporting. Documenting the BD_ADDR is critical for tracking specific assets throughout the engagement. --> Expected Output:

    --> Expected Output:
    [Bottom Pane]
    ...
    BD Address: 00:1A:7D:DA:71:13
    ...

Objective 6: Determine the Device Manufacturer via OUI Action: Select a device. The "OUI" (Organizationally Unique Identifier) is listed, which corresponds to the manufacturer. Ethical Context & Use-Case: The OUI consists of the first three octets of the BD_ADDR. `btscanner` automatically looks this up to identify the manufacturer (e.g., Apple, Intel, Broadcom). This information is highly valuable, as it allows the penetration tester to research manufacturer-specific vulnerabilities. --> Expected Output:

    --> Expected Output:
    [Bottom Pane]
    ...
    OUI: Apple, Inc.
    ...

Objective 7: Interpret the "Name" of a Device Action: View the "Name" column in the top pane or the "Name" field in the bottom pane. Ethical Context & Use-Case: The device name is a human-readable identifier (e.g., "John's MacBook Pro," "Polycom-Conference"). This can reveal the device's owner, function, or operating system. Default names (like "Galaxy S22") can reveal the device model, which is useful for vulnerability research. --> Expected Output:

    --> Expected Output:
    [Top Pane]
    BD Address          Name                 Class
    ---------------------------------------------------
    A4:83:E7:XX:XX:XX   CEO-iPhone-14-Pro    Phone/Smart

Objective 8: Classify a Device by its "Class" Code Action: View the "Class" column or the "Class" field in the detailed view. Ethical Context & Use-Case: The "Class" is a hexadecimal code that indicates the type of device (e.g., computer, phone, audio device). `btscanner` translates this into a human-readable format. This allows for rapid categorization of discovered assets, helping the tester prioritize targets (e.g., a corporate laptop might be a higher priority than a visitor's headset). --> Expected Output:

    --> Expected Output:
    [Bottom Pane]
    ...
    Class: 7a020c (Computer/Laptop, Capturing, Object-Transfer, Networking)
    ...

Objective 9: Analyze the "RSSI" to Estimate Proximity Action: Select a device. The "RSSI" (Received Signal Strength Indicator) value is displayed and updated live. Ethical Context & Use-Case: RSSI indicates the signal strength. A higher value (i.e., closer to 0, e.g., -45 dBm) implies the device is closer, while a lower value (e.g., -85 dBm) implies it is farther away. An ethical hacker can use this to physically locate a device within a room during an authorized physical assessment. --> Expected Output:

    --> Expected Output:
    [Bottom Pane]
    ...
    RSSI: -52
    ...

Objective 10: Monitor "Link Quality" for Connection Stability Action: Select a device. The "Link Quality" value is displayed and updated live. Ethical Context & Use-Case: This value (typically 0-255) represents the quality of the connection. A high, stable value indicates a good connection. Fluctuations could indicate interference or distance. While less critical for pure reconnaissance, it can be an indicator of environmental factors affecting wireless communications. --> Expected Output:

    --> Expected Output:
    [Bottom Pane]
    ...
    Link Quality: 255
    ...

Objective 11-20: Enumerating Common SDP Services

The Service Discovery Protocol (SDP) reveals the services a device offers. The following objectives focus on identifying specific services.

- Objective 11: Identify a Headset Service -> Look for `Service Name: Headset`.

- Objective 12: Identify Hands-Free Audio Gateway -> Look for `Service Name: Hands-Free Audio Gateway`.

- Objective 13: Identify an Object Push Profile (OBEX) -> Look for `Service Name: OBEX Object Push`.

- Objective 14: Identify a File Transfer Profile (FTP) -> Look for `Service Name: OBEX File Transfer`.

- Objective 15: Identify a Personal Area Networking (PAN) Service -> Look for `Service Name: PANU`.

- Objective 16: Identify a Serial Port Profile (SPP) -> Look for `Service Name: Dial-up Networking`.

- Objective 17: Identify a Human Interface Device (HID) Service -> Look for `Service Name: Human Interface Device`.

- Objective 18: Identify an Advanced Audio Distribution Profile (A2DP) -> Look for `Service Name: Audio Source`.

- Objective 19: Identify a Phone Book Access Profile (PBAP) -> Look for `Service Name: Phonebook Access PSE`.

- Objective 20: Identify a SIM Access Profile (SAP) -> Look for `Service Name: SAP`.

Ethical Context & Use-Case: Each discovered service represents a potential vector for interaction or attack. For example, an exposed OBEX File Transfer service on a corporate device could be flagged in a penetration test report as a potential data exfiltration channel. Identifying these services is key to mapping the Bluetooth attack surface.

--> Expected Output (for Objective 13):

    --> Expected Output:
    [Bottom Pane - SDP Info]
    ...
    Service Name: OBEX Object Push
    Service RecHandle: 0x10005
    Service Class ID List:
      "OBEX Object Push" (0x1105)
    Protocol Descriptor List:
      "L2CAP" (0x0100)
      "RFCOMM" (0x0003)
        Channel: 9
      "OBEX" (0x0008)
    ...

Objective 21-70: Scenario-Based Reconnaissance

These objectives simulate real-world scenarios an ethical hacker might face, demonstrating how to interpret `btscanner` data in context. The command is always `sudo btscanner`, but the analysis is unique.

- Objective 21: Identify a Skimmer on an ATM: Look for a non-standard Bluetooth device with a generic name (e.g., "HC-05," "BT-Module") with a strong, constant RSSI near the ATM.

- Objective 22: Locate a CEO's Phone in a Boardroom: Look for a device name like "John Doe's iPhone" and use the RSSI value to pinpoint its location by walking around the room.

- Objective 23: Find Unauthorized Peripherals in a Server Room: Scan for HID class devices (keyboards, mice) that are not part of the official inventory.

- Objective 24: Discover a Corporate Wireless Presenter: Look for a device advertising HID services with a name like "Logitech Presenter R800."

- Objective 25: Identify a Smartwatch: Look for device names containing "Watch" and a class indicating a wearable device.

- Objective 26: Find a Bluetooth-Enabled Printer: Search for a device advertising a Basic Printing Profile (BPP) or with a name like "HP OfficeJet."

- Objective 27: Enumerate Vehicle Bluetooth Systems: In a vehicle assessment, look for names like "Uconnect," "SYNC," or "Car-Audio" that expose Hands-Free profiles.

- Objective 28: Identify a Rogue Access Point: Look for a device advertising a PANU or NAP service with a suspicious name.

- Objective 29: Discover IoT Devices: Search for devices with generic names and unusual service profiles, often from less-common OUIs (e.g., Espressif Inc.).

- Objective 30: Assess a Guest Kiosk: Scan for any discoverable Bluetooth devices on a public-facing kiosk which could be an oversight.

- Objective 31: Differentiate Between two Identical Phones: Use their unique BD_ADDRs to distinguish them, even if they have the same name.

- Objective 32: Detect a Bluetooth Tracking Tag: Look for a device with a very low-power profile, a frequently changing address (if LE), and a manufacturer like "Tile" or "Apple." (Note: `btscanner` is better for classic Bluetooth).

- Objective 33: Find a Medical Device: During a healthcare facility assessment, look for devices with OUIs corresponding to medical equipment manufacturers.

- Objective 34: Identify a Point-of-Sale (POS) System: Search for devices advertising Serial Port Profile (SPP) which are often used for receipt printers or card readers.

- Objective 35-40: Deconstructing Device Class Codes: Analyze the major/minor device class bits to manually confirm `btscanner`'s interpretation for a Computer, Phone, LAN Access Point, Audio Device, Peripheral, and Imaging device.

- Objective 41-50: Interpreting HCI Information: Analyze the HCI Version, Revision, and supported features for a selected device to understand its Bluetooth specification level (e.g., 4.0, 5.1), which indicates its security features.

- Objective 51: Note the Absence of a Device Name: A device with a BD_ADDR but no name can be suspicious and warrants further investigation.

- Objective 52: Monitor RSSI Fluctuation: Watch the RSSI value change as you move your scanning device. A rapid increase indicates you're moving closer to the target.

- Objective 53: Refresh the Device List: Pressing 'i' in the interface forces a new inquiry scan to find new devices that have come into range.

- Objective 54: Sort Devices by Address: Press 'b' to sort the discovered devices by their BD_ADDR.

- Objective 55: Sort Devices by Name: Press 'n' to sort the list by device name.

- Objective 56: Sort Devices by Class: Press 'c' to sort the list by device class.

- Objective 57: Quit the Application: Press 'q' to exit the `btscanner` interface.

- Objective 58: Identify a Device Broadcasting "Limited Discoverable Mode": Note if a device appears and then disappears from the scan list frequently.

- Objective 59: Correlate OUI with a Laptop: Identify a device with an OUI of "Dell" or "HP" and a device class of "Computer/Laptop."

- Objective 60-70: Comprehensive Reconnaissance Report: Systematically go through each discovered device in a given scenario (e.g., an office floor) and document its BD_ADDR, OUI, Name, Class, and all discovered SDP services in your penetration testing report notes. Each device represents a unique case study in data interpretation.

#### Strategic Campaigns: Advanced Command Chains

While `btscanner` is an interactive tool, its output can be captured and processed by other command-line utilities to filter and analyze data more efficiently.

#### Objective: Capture Scan Output and Find All Apple Devices

This chain runs `btscanner`, captures its screen output to a file, and then uses `grep` to filter for devices manufactured by Apple.

Command:

Bash

    sudo script -q -c "btscanner" /dev/null | tee btscan.log && grep "Apple" btscan.log

Command Breakdown:

- `sudo script -q -c "btscanner" /dev/null`: Runs `btscanner` within a `script` session. `script` is a utility that captures everything printed to the terminal. `-q` is for quiet mode, and `-c` specifies the command to run. We redirect the timing file to `/dev/null`.

- `| tee btscan.log`: Simultaneously displays the output to the screen and saves it to a file named `btscan.log`. (Note: This is a simplified representation; interactive ncurses output can be messy).

- `&&`: Executes the next command only if the first one succeeds.

- `grep "Apple" btscan.log`: Searches the captured log file for any lines containing the string "Apple".

Ethical Context & Use-Case: In a large-scale assessment with dozens of devices, manually reviewing each one is inefficient. This command chain automates the process of identifying devices from a specific manufacturer known to be used by the target company. This allows the tester to quickly focus on corporate-owned assets, which are typically of higher interest than personal devices.

--> Expected Output:

    --> Expected Output:
    OUI: Apple, Inc.
    OUI: Apple, Inc.
    OUI: Apple, Inc.

(The output will contain lines from the log file where "Apple" was found.)

#### Objective: Reset Bluetooth Adapter and Immediately Launch a Non-Resetting Scan

This sequence manually resets the local Bluetooth adapter (`hci0`) before launching `btscanner` with the `--no-reset` flag.

Command:

Bash

    sudo hciconfig hci0 down && sudo hciconfig hci0 up && sudo btscanner --no-reset

Command Breakdown:

- `sudo hciconfig hci0 down`: Deactivates the primary Bluetooth adapter (`hci0`).

- `&&`: Logical AND operator; the next command runs only if the previous one was successful.

- `sudo hciconfig hci0 up`: Activates the primary Bluetooth adapter.

- `sudo btscanner --no-reset`: Launches `btscanner` but tells it to skip its own internal reset procedure, as we have just performed one manually.

Ethical Context & Use-Case: This provides granular control over the hardware state. Sometimes, a full manual power cycle of the adapter using `hciconfig` can resolve driver or hardware issues more reliably than a software-initiated reset. An ethical hacker might use this technique to ensure their scanning hardware is in a clean, predictable state before beginning a formal reconnaissance phase of an engagement.

--> Expected Output: [VISUAL OUTPUT: The `btscanner` Ncurses interface appears and immediately begins scanning for devices, having skipped its own reset routine.]

#### Objective: Extract Device Addresses and Names from Log using `awk`

This command chain processes a previously captured `btscanner` log to extract a clean, simple list of device addresses and names.

Command:

Bash

    grep 'BD Address:\|Name:' btscan.log | awk '{print $NF}' | paste -d " " - -

Command Breakdown:

- `grep 'BD Address:\|Name:' btscan.log`: Filters the log file, showing only lines that contain "BD Address:" or "Name:".

- `|`: Pipes the output of `grep` to the `awk` command.

- `awk '{print $NF}'`: For each line of input, `awk` prints the last field (`$NF`). This effectively extracts the address and the name.

- `paste -d " " - -`: Takes the stream of output from `awk` (which is a list of addresses and names on separate lines) and merges pairs of consecutive lines into a single line, separated by a space.

Ethical Context & Use-Case: Effective reporting is a key part of ethical hacking. A raw tool log is often too verbose for a final report. This command chain is used to parse the raw data and format it into a clean, concise list of discovered assets. This list can then be easily imported into a spreadsheet or reporting tool for further analysis and documentation.

--> Expected Output:

    --> Expected Output:
    00:1A:7D:DA:71:13 Corporate-Printer-4
    A4:83:E7:BC:92:A1 CEO-iPhone-14-Pro
    88:0F:10:AE:3B:7C Conference-Speaker

#### AI Augmentation: Integrating with Artificial Intelligence

Leveraging AI can transform raw `btscanner` output into actionable intelligence, identifying anomalies and enriching data far beyond manual capabilities.

#### Objective: Use Python and Pandas to Analyze and Classify Devices

This example outlines a Python script that would parse a `btscanner` log file, classify devices, and flag potential anomalies for review.

Toolchain:

Python

    # ai_btscan_analyzer.py
    import pandas as pd
    import re

    def parse_log(log_file):
        with open(log_file, 'r') as f:
            content = f.read()

        # Use regex to find device entries (simplistic example)
        # A real parser would be more robust
        addresses = re.findall(r'BD Address: ([\w:]+)', content)
        names = re.findall(r'Name: ([\w\s-]+)', content)
        ouis = re.findall(r'OUI: ([\w\s,.-]+)', content)

        # Create a DataFrame
        df = pd.DataFrame({
            'BD_Address': addresses[:len(names)], # Align lengths
            'Name': names,
            'OUI': ouis[:len(names)]
        })
        return df

    def analyze_devices(df):
        # AI/ML logic placeholder: In a real scenario, you might use a trained model.
        # Here, we use rule-based logic to simulate AI classification.
        corporate_keywords = ['Corporate', 'CEO', 'OfficeJet', 'Polycom']
        suspicious_names = ['HC-05', 'BT-Module', 'RN-42']

        df['Classification'] = 'Unknown'
        df.loc[df['OUI'].str.contains('Apple|Dell|HP', case=False), 'Classification'] = 'Standard Corporate'
        df.loc[df['Name'].str.contains('|'.join(corporate_keywords), case=False), 'Classification'] = 'High-Value Target'
        df.loc[df['Name'].str.contains('|'.join(suspicious_names), case=False), 'Classification'] = 'Potential Rogue Device'

        return df

    # --- Main Execution ---
    # Assumes a btscan.log file exists from the previous chaining example.
    log_data = parse_log('btscan.log')
    analyzed_data = analyze_devices(log_data)

    print("AI-Augmented Bluetooth Device Analysis:")
    print(analyzed_data.to_string())

Command Breakdown:

- `parse_log` function: Reads the log file and uses regular expressions to extract key information like BD Address, Name, and OUI.

- `pandas.DataFrame`: Structures the extracted data into a table-like format for easy manipulation.

- `analyze_devices` function: This is the core "AI" component. It applies a set of rules to classify devices. A true AI system would use a machine learning model trained on thousands of device profiles to make these classifications with higher accuracy.

- Classification Logic: It flags devices as standard corporate assets, potential high-value targets, or suspicious rogue devices based on their OUI and name.

Ethical Context & Use-Case: When assessing a large corporate environment, an ethical hacker can be inundated with hundreds of Bluetooth devices. Manually sifting through this data is impossible. This AI-augmented approach automates the initial triage. The script can instantly highlight devices that deviate from the corporate standard (e.g., a device with a generic module name like "HC-05" in a secure area) or identify high-value targets, allowing the penetration tester to focus their efforts where the risk is highest.

--> Expected Output:

    --> Expected Output:
    AI-Augmented Bluetooth Device Analysis:
              BD_Address                 Name             OUI      Classification
    0  00:1A:7D:DA:71:13  Corporate-Printer-4              HP  High-Value Target

    2  3C:28:6D:11:22:33               HC-05   Espressif Inc  Potential Rogue Device

#### Objective: Generate an Executive Summary with an LLM

This example demonstrates how to use the processed data as a prompt for a Large Language Model (LLM) to generate a human-readable summary for a report.

Toolchain: A prompt is crafted for an LLM (like Google's Gemini or OpenAI's GPT series) using the output from the previous Python script.

LLM Prompt:

    As a senior cybersecurity analyst, review the following Bluetooth device data discovered during a penetration test and write a brief executive summary (2-3 paragraphs). The data is in a table format. Focus on identifying potential risks and recommending next steps.

    Discovered Devices:
    | BD_Address        | Name                | OUI             | Classification         |
    |-------------------|---------------------|-----------------|------------------------|
    | 00:1A:7D:DA:71:13 | Corporate-Printer-4 | HP              | High-Value Target      |
    | A4:83:E7:BC:92:A1 | CEO-iPhone-14-Pro   | Apple, Inc.     | High-Value Target      |
    | 3C:28:6D:11:22:33 | HC-05               | Espressif Inc   | Potential Rogue Device |

Command Breakdown:

- Role-playing: The prompt instructs the LLM to act as a specific persona ("senior cybersecurity analyst") to ensure the tone and content of the output are appropriate.

- Contextual Data: The cleaned and classified data from the Python script is provided directly to the LLM.

- Clear Instruction: The prompt explicitly asks the LLM to write an executive summary, identify risks, and recommend actions.

Ethical Context & Use-Case: A significant part of ethical hacking is communicating findings to stakeholders, who may not be technical. An LLM can be used as a powerful assistant to rapidly translate raw technical data into a well-written narrative. This saves the penetration tester valuable time on report writing, allowing them to focus on technical validation. The LLM's output serves as a first draft that the tester then reviews, verifies, and refines for the final report.

--> Expected Output: [VISUAL OUTPUT: A text block containing a professionally written executive summary.]

Example LLM-Generated Text:

"During the recent physical security assessment, a scan of the Bluetooth radio frequency spectrum identified several active devices. The findings indicate the presence of both standard corporate assets and at least one anomalous device that warrants immediate investigation. High-value targets, including a corporate printer and a device named 'CEO-iPhone-14-Pro', were discovered and are considered within the expected profile for this environment.

Of particular concern is the identification of a device with the generic name 'HC-05', classified as a potential rogue device. Such devices are often associated with unauthorized or hobbyist electronics and their presence in a corporate setting could represent a potential data exfiltration channel or an unauthorized access point. We recommend a physical sweep of the assessed area to locate this device.
