To conduct reconnaissance and identify hardware and software used by a client, job boards are an effective resource. Companies often list the technologies they use in job postings to attract qualified candidates. These listings can provide valuable insights into the specific hardware and software platforms the client is utilizing.

Reconnaissance:

This is the first phase in penetration testing, involving gathering as much information as possible about the target.

Reconnaissance can be divided into two types: passive and active. Job boards fall under passive reconnaissance, where the tester gathers information without directly interacting with the target systems.

Job Boards:

Job postings often include detailed descriptions of the technologies and tools used within the company.

For example, a job posting for a network administrator might list specific brands of hardware (like Cisco routers) or software (like VMware).

Examples of Job Boards:

Websites like LinkedIn, Indeed, Glassdoor, and company career pages can be used to find relevant job postings.

These postings might mention operating systems (Windows, Linux), development frameworks (Spring, .NET), databases (Oracle, MySQL), and more.

Pentest References:

OSINT (Open Source Intelligence): Using publicly available sources to gather information about a target.

Job boards are a key source of OSINT, providing indirect access to the internal technologies of a company.

This information can be used to tailor subsequent phases of the penetration test, such as vulnerability scanning and exploitation, to the specific technologies identified.

By examining job boards, a penetration tester can gain insights into the hardware and software environments of the target, making this a valuable reconnaissance tool.

=================

The key detail in the Nmap scan output is that port 2222/tcp is open and running the SSH service. The standard SSH port is 22, so if the tester was attempting to connect on port 22, they would not succeed because SSH is instead listening on port 2222.

This is a common security hardening tactic—moving services to non-standard ports to reduce automated attacks.

There is no indication that the service is blocked (B), or requires certificates (C), or is inactive (D), because Nmap clearly shows the service is open and identified.

CompTIA PenTest+ Reference:

PT0-003 Objective 3.3: Analyze tool output or data related to engagement activities.

Nmap usage and interpreting scan results is emphasized in multiple sections.

An attack narrative is a crucial part of a penetration testing report. It explains how the tester was able to exploit vulnerabilities, providing a story-like structure of the attack path taken. This helps the client understand the sequence of actions, from initial access to potential compromise, and the real-world impact.

The attack narrative often includes:

Initial access methods

Privilege escalation steps

Lateral movement within the network

Data exfiltration scenarios

Tools and techniques used

According to the CompTIA PenTest+ PT0-003 Official Study Guide (Chapter 11: Reporting and Communication):

“The attack narrative should be a detailed timeline of the tester’s actions, findings, and techniques used during the assessment. It allows technical and non-technical stakeholders to understand the context of the findings.”

The tester’s activity involves analyzing the contents of a JAR file to identify potentially vulnerable components. This process is known as Software Composition Analysis (SCA). Here’s why:

Understanding SCA:

Definition: SCA involves analyzing software to identify third-party and open-source components, checking for known vulnerabilities, and ensuring license compliance.

Purpose: To detect and manage risks associated with third-party software components.

Comparison with Other Terms:

SAST (A): Static Application Security Testing involves analyzing source code for security vulnerabilities without executing the code.

SBOM (B): Software Bill of Materials is a detailed list of all components in a software product, often used in SCA but not the analysis itself.

ICS (C): Industrial Control Systems, not relevant to the context of software analysis.

The tester’s activity of examining a JAR file for vulnerable components aligns with SCA, making it the correct answer.

=================

Lock picking techniques are used in physical security assessments to test access control mechanisms.

Raking (Option D):

Raking is a lock-picking technique where a rake pick is inserted and rapidly moved in and out to manipulate multiple pins simultaneously.

It is faster but less precise than single-pin picking.

Used when speed is prioritized over precision.

Since SSID broadcast might be hidden, channel scanning allows the tester to identify active Wi-Fi networks.

Option A (Sidecar scanning) ❌: Not a recognized Wi-Fi testing method.

Option B (Channel scanning) ✅: Correct.

Identifies hidden SSIDs by monitoring probe requests and responses.

Option C (Stealth scanning) ❌: Typically refers to evading detection, not Wi-Fi analysis.

Option D (Static analysis scanning) ❌: Static analysis applies to code security, not Wi-Fi networks.

Since direct interaction with the ICS application is restricted, the best way to analyze network traffic without modifying the system is to use port mirroring on a firewall or network switch.

Option A (Port mirroring) ✅:

Correct. Port mirroring (SPAN) copies network traffic without modifying the host system.

Allows passive analysis of whether encryption is used.

Option B (Packet capture on the server) ❌:

Requires modifying the host, which is prohibited by the client.

Option C (Reconfiguring the app to use a proxy) ❌:

Modifies application settings, which violates the client’s terms.

Option D (Disabling certificate pinning) ❌:

Requires changes to security settings, which is not allowed in this scenario.

To assess wireless communication disruptions, channel scanning is used to identify active Wi-Fi channels, allowing testers to target specific frequencies for jamming or deauthentication attacks.

Option A (Port mirroring) ❌: Used for network traffic monitoring, not wireless disruption.

Option B (Sidecar scanning) ❌: Not a commonly used technique in wireless testing.

Option C (ARP poisoning) ❌: Used to manipulate ARP tables on wired networks, not for wireless interference.

Option D (Channel scanning) ✅: Correct.

Identifies which Wi-Fi channels are in use.

Helps perform jamming, deauthentication, or interference attacks.
