CompTIA Updated PT0-003 Exam Questions and Answers by aura

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.

Luke HTB: Highlights the process of testing for XSS by injecting scripts and observing their execution in the browser​​.

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

OpenID Connect (OIDC) with OAuth allows applications to authenticate users using third-party identity providers (IdPs). If dynamic registration is enabled, attackers can abuse this feature to capture and replay authentication requests.

Replay attack (Option C):

Attackers capture legitimate authentication tokens and reuse them to impersonate users.

OIDC uses JWTs (JSON Web Tokens), which may not expire quickly, making replay attacks highly effective.

The tester is conducting a phishing attack by cloning the company's login page to steal employee credentials.

Option A (BeEF) ❌: BeEF is used for browser exploitation, not phishing.

Option B (theHarvester) ❌: Used for OSINT, gathering emails, but does not conduct phishing attacks.

Option C (SET - Social Engineering Toolkit) ✅: Correct.

SET allows testers to clone web pages and perform phishing attacks.

Option D (GoPhish) ❌: GoPhish is a phishing simulation tool, but SET is specifically designed for credential harvesting.

When the client indicates that the scope's hosts and assets are not included in the vulnerability scan results, it suggests that the tester may have missed discovering all the devices in the scope. Here’s the best course of action:

Performing a Discovery Scan:

Purpose: A discovery scan identifies all active devices on the network before running a detailed vulnerability scan. It ensures that all in-scope devices are included in the assessment.

Process: The discovery scan uses techniques like ping sweeps, ARP scans, and port scans to identify active hosts and services.

Comparison with Other Actions:

Rechecking the Scanner Configuration (A): Useful but not as comprehensive as ensuring all hosts are discovered.

Using a Different Scan Engine (C): Not necessary if the issue is with host discovery rather than the scanner’s capability.

Configuring All TCP Ports on the Scan (D): Helps in detailed scanning but does not address missing hosts.

Performing a discovery scan ensures that all in-scope devices are identified and included in the vulnerability assessment, making it the best course of action.
