Raking is a lockpicking technique where the attacker quickly manipulates the lock pins to open a pin tumbler lock.

Option A (Plug spinner) ❌: Used to reverse the direction of a lock cylinder after a successful pick.

Option B (Bypassing) ❌: Uses alternative methods (shimming, credit card entry) but does not manipulate pins.

Option C (Decoding) ❌: Determines key bitting (shape of key cuts), but does not directly open the lock.

Option D (Raking) ✅: Correct.

A quick lockpicking technique that manipulates multiple pins at once.

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.

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

If a wireless network uses weak encryption (e.g., WEP), attackers can capture and analyze packets to extract sensitive data.

Packet sniffing (Option C):

Tools like Wireshark, Aircrack-ng, and Kismet capture network packets.

Attackers analyze captured traffic to decrypt WEP encryption or extract plaintext credentials.

The tester gained information by listening to a private discussion, which is eavesdropping (passive reconnaissance).

Option A (Eavesdropping) ✅: Correct.

Involves intercepting conversations via audio, network traffic, or wireless signals.

Option B (Bluesnarfing) ❌: Stealing data via Bluetooth, which is not mentioned.

Option C (Credential harvesting) ❌: No password collection occurred.

Option D (SQL injection) ❌: SQLi affects databases, not voice communications.
