CompTIA Updated PT0-003 Exam Questions and Answers by uthman

WiFi-Pumpkin is used for man-in-the-middle (MitM) attacks on Wi-Fi networks, making it ideal for intercepting and accessing data.

Option A (Metasploit) ❌: Good for exploitation, but not specialized for Wi-Fi attacks.

Option B (WiFi-Pumpkin) ✅: Correct.

Creates fake Wi-Fi access points.

Intercepts network traffic (SSL stripping, DNS spoofing).

Option C (SET - Social Engineering Toolkit) ❌: Focuses on phishing, not Wi-Fi attacks.

Option D (theHarvester) ❌: Used for OSINT, not Wi-Fi exploitation.

Option E (WiGLE.net) ❌: Maps Wi-Fi networks, but does not capture sensitive data.

Penetration testers search for hardcoded credentials, API keys, and authentication tokens in source code repositories to identify secrets leakage.

Secrets scanning (Option B):

The find and egrep command scans all files recursively for sensitive keywords like "token," "key," and "login".

Attackers use tools like TruffleHog and GitLeaks to automate secret discovery.

Responder is a tool used for capturing and analyzing NetBIOS, LLMNR, and MDNS queries to perform various man-in-the-middle (MITM) attacks. It can be used to capture hashed credentials, which can then be cracked offline. Using Responder has the least impact on the host's operating stability compared to more aggressive methods like buffer overflow attacks or payload injections.

Understanding Responder:

Purpose: Responder is used to capture NTLMv2 hashes from a Windows network.

Operation: It listens on the network for LLMNR, NBT-NS, and MDNS requests and responds to them, tricking the client into authenticating with the attacker's machine.

Command Breakdown:

responder -I eth0: Starts Responder on the network interface eth0.

john responder_output.txt: Uses John the Ripper to crack the hashes captured by Responder.

: Suggests the next step after capturing credentials might involve using RDP with the cracked password, but the initial capture is passive and low impact.

Why This is the Best Choice:

Least Impact: Responder passively captures network traffic without interacting directly with the target host’s system processes.

Stealth: It operates quietly on the network, making it less likely to cause stability issues or be detected by host-based security mechanisms.

References from Pentesting Literature:

Tools like Responder are discussed in penetration testing guides for initial reconnaissance and credential gathering without causing significant disruptions.

HTB write-ups frequently mention the use of Responder in network-based attacks to capture credentials safely.

Comprehensive and Detailed Explanation:

The vulnerability report identifies a TLS vulnerability on port 443 (HTTPS). However, the Nmap scan shows port 443 as closed, meaning the service is not running or reachable.

If the service associated with the vulnerability is not active, the reported issue cannot be valid. Therefore, the scan result contradicts the finding — making it a false positive (the scanner incorrectly flagged a vulnerability that doesn’t exist).

Why not the others:

A. True negative: Would mean no vulnerability exists and none was reported.

B. True positive: Would mean both the scan and vulnerability report agree that the service is running and vulnerable — not the case here.

C. False negative: Would mean a vulnerability exists but was not detected — also not the case.
