PenTest+ Changed PT0-003 Questions

To see any vulnerabilities that may be visible from outside of the organization, the penetration tester should perform an unauthenticated scan.

Unauthenticated Scan:

Definition: An unauthenticated scan is conducted without providing any credentials to the scanning tool. It simulates the perspective of an external attacker who does not have any prior access to the system.

Purpose: Identifies vulnerabilities that are exposed to the public and can be exploited without authentication. This includes open ports, outdated software, and misconfigurations visible to the outside world.

Comparison with Other Scans:

SAST (Static Application Security Testing): Analyzes source code for vulnerabilities, typically used during the development phase and not suitable for external vulnerability scanning.

Sidecar: This term is generally associated with microservices architecture and is not relevant to the context of vulnerability scanning.

Host-based: Involves scanning from within the network and often requires authenticated access to the host to identify vulnerabilities. It is not suitable for determining external vulnerabilities.

Pentest References:

External Vulnerability Assessment: Conducting unauthenticated scans helps identify the attack surface exposed to external threats and prioritizes vulnerabilities that are accessible from the internet.

Tools: Common tools for unauthenticated scanning include Nessus, OpenVAS, and Nmap.

By performing an unauthenticated scan, the penetration tester can identify vulnerabilities that an external attacker could exploit without needing any credentials or internal access.

The tool that the penetration tester should use for further investigation is WPScan. This is because WPScan is a WordPress vulnerability scanner that can detect common WordPress security issues, such as weak passwords, outdated plugins, and misconfigured settings. WPScan can also enumerate WordPress users, themes, and plugins from the robots.txt file.

The two entries in the robots.txt file that the penetration tester should recommend for removal are:

Allow: /admin

Allow: /wp-admin

These entries expose the WordPress admin panel, which can be a target for brute-force attacks, SQL injection, and other exploits. Removing these entries can help prevent unauthorized access to the web application’s backend. Alternatively, the penetration tester can suggest renaming the admin panel to a less obvious name, or adding authentication methods such as two-factor authentication or IP whitelisting.

Comprehensive and Detailed Explanation From Exact Extract:

net.exe is the classic Windows networking utility that includes commands for enumerating domain resources and accounts from a compromised host where the tester has any authenticated domain context. Typical commands used by penetration testers to enumerate domain users with net.exe include:

net user /domain — lists domain user accounts (name and some properties).

net group " Domain Users " /domain — lists members of the Domain Users group.

net view /domain — lists computers in the domain (useful to find targets for further enumeration).

Why net.exe is the best option here:

It is installed by default on Windows systems and works with the current authenticated domain credentials (common after gaining a foothold).

It provides a quick, low-noise way to enumerate user accounts and groups without requiring additional tooling or elevated privileges beyond an authenticated domain user.

Results can be scripted and parsed for further enumeration and pivoting.

Why the other options are not appropriate:

A. pwd.exe — Not a standard Windows tool for domain enumeration (and not present by default).

C. sc.exe — Service Controller tool for managing services; not used to enumerate domain users.

D. msconfig.exe — System configuration GUI utility for startup/services; not for domain account enumeration.

Related alternatives (contextual, commonly used in pentests):

dsquery user -limit 0 (on systems with RSAT/AD tools) to query AD directly.

Get-ADUser -Filter * (PowerShell, requires the ActiveDirectory module and appropriate rights).

Tools like PowerView (PowerShell) or BloodHound (collection phase) can provide richer AD enumeration, but net.exe is the simplest built-in option to enumerate domain users from an authenticated foothold.

CompTIA PT0-003 Objective Mapping (summary):

Domain 2.0 Information Gathering and Vulnerability Scanning — enumerate network and Active Directory objects using native tools and scripts (e.g., net.exe for domain user enumeration).

The command airodump-ng -c 6 --bssid < target_mac > < iface > is used to capture WPA/WPA2 4-way handshakes on a specific channel and BSSID. This handshake is necessary for offline password cracking using tools like Hashcat or John the Ripper.

From the CompTIA PenTest+ PT0-003 Official Study Guide (Chapter 7 – Wireless Attacks):

“Airodump-ng is used to capture handshakes between a client and access point. The attacker can then attempt to crack the captured handshake offline.”
