CompTIA PT0-003 Dumps Questions Answers

Pivoting allows attackers to use a compromised host as a gateway to access internal resources.

Create an SSH tunnel using sshuttle (Option A):

sshuttle creates a transparent VPN-like connection over SSH, allowing the tester to forward traffic securely.

Advantages:

Provides encryption, preventing IDS/IPS detection.

Requires minimal interaction with the compromised host.

The logs indicate that the penetration testing team’s objective was to create persistence in the network.

Log Analysis:

schtasks /query: This command lists all the scheduled tasks on the system. It is often used to understand what tasks are currently scheduled and running.

schtasks /CREATE /SC DAILY: This command creates a new scheduled task that runs daily. Creating such a task can be used to ensure that a script or program runs regularly, maintaining a foothold in the system.

Persistence:

Definition: Persistence refers to techniques used to maintain access to a compromised system even after reboots or other interruptions.

Scheduled Tasks: One common method of achieving persistence on Windows systems is by creating scheduled tasks that execute malicious payloads or scripts at regular intervals.

Other Options:

Enumerate Current Users: The logs do not show commands related to user enumeration.

Determine Users' Permissions: Commands like whoami or net user would be more relevant for checking user permissions.

View Scheduled Processes: While schtasks /query can view scheduled tasks, the addition of the schtasks /CREATE command indicates the intent to create new scheduled tasks, which aligns with creating persistence.

Pentest References:

Post-Exploitation: Establishing persistence is a key objective after gaining initial access to ensure continued access.

Scheduled Tasks: Utilizing Windows Task Scheduler to run scripts or programs automatically at specified times as a method for maintaining access.

By creating scheduled tasks, the penetration testing team aims to establish persistence, ensuring they can retain access to the system over time.

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

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.
