Conclusion:

Option D, recommendations, is the correct section where the given statements would be found in a penetration test report.

C. Modbus

Answer DescriptionExplanation:

Operational Technology (OT) protocols are used in industrial control systems (ICS) to manage and automate physical processes. Here’s an analysis of each protocol regarding whether it sends information in cleartext:

TTEthernet (Option A):

Explanation:

TTEthernet (Time-Triggered Ethernet) is designed for real-time communication and safety-critical systems.

Security:

It includes mechanisms for reliable and deterministic data transfer, not typically sending information in cleartext.

DNP3 (Option B):

Explanation:

DNP3 (Distributed Network Protocol) is used in electric and water utilities for SCADA (Supervisory Control and Data Acquisition) systems.

Security:

While the original DNP3 protocol transmits data in cleartext, the DNP3 Secure Authentication extensions provide cryptographic security features.

Modbus (Answer: C):

Explanation:

Modbus is a communication protocol used in industrial environments for transmitting data between electronic devices.

Security:

Modbus transmits data in cleartext, which makes it susceptible to interception and unauthorized access.

References:

The lack of security features in Modbus, such as encryption, is well-documented and a known vulnerability in ICS environments.

PROFINET (Option D):

Explanation:

PROFINET is a standard for industrial networking in automation.

Security:

PROFINET includes several security features, including support for encryption, which means it doesn’t necessarily send information in cleartext.

Conclusion:

Modbus is the protocol that most commonly sends information in clear text, making it vulnerable to eavesdropping and interception.

C. XSS

Answer DescriptionExplanation:

Cross-Site Scripting (XSS) is an attack that involves injecting malicious scripts into web pages viewed by other users. Here’s why option C is correct:

XSS (Cross-Site Scripting): This attack involves injecting JavaScript into a web application, which is then executed by the user’s browser. The scenario describes injecting a JavaScript prompt, which is a typical XSS payload.

SQL Injection: This involves injecting SQL commands to manipulate the database and does not relate to JavaScript injection.

SSRF (Server-Side Request Forgery): This attack tricks the server into making requests to unintended locations, which is not related to client-side JavaScript execution.

Server-Side Template Injection: This involves injecting code into server-side templates, not JavaScript that executes in the user’s browser.

References from Pentest:

Horizontall HTB: Demonstrates identifying and exploiting XSS vulnerabilities in web applications. Luke HTB: Highlights the process of testing for XSS by injecting scripts and observing their execution in the browser.

D. SAST

Answer Description

D. Metadata services

Answer Description

C. Service discovery

Answer Description

A. Report the finding.

Answer DescriptionExplanation:

Upon discovering evidence of an advanced persistent threat (APT) on the network, the penetration tester should report the finding immediately.

Explanation:

Advanced Persistent Threat (APT):

Definition: APTs are prolonged and targeted cyberattacks in which an intruder gains access to a network and remains undetected for an extended period.

Significance: APTs often involve sophisticated tactics, techniques, and procedures (TTPs) aimed at stealing data or causing disruption.

Immediate Reporting:

Criticality: Discovering an APT requires immediate attention from the organization’s security team due to the potential impact and persistence of the threat.

Chain of Command: Following the protocol for reporting such findings ensures that appropriate incident response measures are initiated promptly.

Other Actions:

Analyzing the Finding: While analysis is important, it should be conducted by the incident response team after reporting.

Removing the Threat: This action should be taken by the organization’s security team following established incident response procedures.

Documenting and Continuing Testing: Documentation is crucial, but the immediate priority should be reporting the APT to ensure prompt action.

Pentest References:

Incident Response: Understanding the importance of immediate reporting and collaboration with the organization’s security team upon discovering critical threats like APTs. Ethical Responsibility: Following ethical guidelines and protocols to ensure the organization can respond effectively to significant threats.

By reporting the finding immediately, the penetration tester ensures that the organization’s security team is alerted to the presence of an APT, allowing them to initiate an appropriate incident response.

C. Tailgating

Answer DescriptionExplanation:

Tailgating is the term used to describe a situation where a penetration tester bypasses physical access controls and gains access to a facility by entering at the same time as an employee. Explanation:

Tailgating:

Definition: Tailgating occurs when an unauthorized person follows an authorized person into a restricted area without the latter’s consent or knowledge. The authorized person typically opens a door or checkpoint, and the unauthorized person slips in behind them.

Example: An attacker waits near the entrance of a building and enters right after an employee, bypassing security measures.

Physical Security:

Importance: Physical security is a crucial aspect of overall security posture. Tailgating exploits human factors and weaknesses in physical security controls.

Prevention: Security measures such as turnstiles, mantraps, and security personnel can help prevent tailgating.

Pentest References:

Physical Penetration Testing: Tailgating is a common technique used in physical penetration tests to assess the effectiveness of an organization’s physical security controls.

Social Engineering: Tailgating often involves social engineering, where the attacker relies on the politeness or unawareness of the employee to gain unauthorized access.

By understanding and using tailgating, penetration testers can evaluate the effectiveness of an organization’s physical security measures and identify potential vulnerabilities that could be exploited by malicious actors.
