All 312-50v13 Test Inside ECCouncil Questions

In CEH v13 Module 03: Scanning Networks, Nmap's evasion techniques are discussed for bypassing or confusing Intrusion Detection Systems (IDS) and firewalls.

The -D option in Nmap is used to enable decoy scanning. It inserts false IP addresses in the scan to obfuscate the true origin of the scan.

This technique helps in masking the attacker’s IP and can confuse IDS logs.

Option Clarification:

A. -n/-R: Disables DNS resolution (-n) or uses reverse DNS (-R), does not evade detection.

B. -0N/-0X/-0G: Output formats (normal, XML, grepable), not related to evasion.

C. -T: Controls timing (e.g., -T0 is stealthy, -T5 is aggressive), but not explicitly for IDS evasion.

D. -D: Correct. Used for IDS/firewall evasion by using decoy IPs.

In CEH v13 Module 02: Footprinting and Reconnaissance, Dark Web Footprinting is discussed as an advanced form of reconnaissance where attackers access hidden services and data using anonymity networks such as Tor (The Onion Router), I2P, or Freenet. These networks enable access to the deep web and dark web, where unindexed, and often illicit, content resides.

Key points relevant to this scenario:

The attacker encrypted browsing traffic and navigated anonymously, which strongly implies the use of tools like Tor or VPNs to mask identity.

The attacker used specialized tools/search engines like:

Torch

Ahmia

DarkSearch

Candle

The goal was to find sensitive or hidden information in government or federal systems — a common dark web footprinting objective.

The final step involved an attack that left no trace, which aligns with using the dark web for anonymity and obfuscation.

Option Analysis:

A. Dark web footprinting

Correct. This matches the behavior described: encrypted, anonymous access to sensitive information through dark web tools.

B. VoIP footprinting ❌

Incorrect. VoIP footprinting relates to identifying vulnerabilities or metadata in Voice over IP systems, not anonymous browsing or dark web activities.

C. VPN footprinting ❌

Incorrect. While VPNs may be used as part of anonymity, VPN footprinting refers to identifying systems using VPNs — not the act of gathering data anonymously.

D. Website footprinting ❌

Incorrect. Website footprinting involves gathering information from public-facing websites, like WHOIS data, robots.txt, and HTML metadata — not hidden dark web content.

The scenario describes a hybrid encryption solution based on the OpenPGP standard that uses both symmetric and asymmetric encryption. The key phrase in the question is “a free implementation of the OpenPGP standard,” which directly refers to GPG.

GPG (GNU Privacy Guard) is a free, open-source implementation of the OpenPGP standard.

It combines symmetric encryption for data encryption (fast and efficient) and asymmetric encryption for secure key exchange (using public/private key pairs).

GPG is widely used to secure emails, files, and messages, often in conjunction with tools like Thunderbird or command-line utilities.

Incorrect Options:

A. PGP (Pretty Good Privacy) is the original proprietary implementation of OpenPGP, not free/open-source by default.

B. S/MIME (Secure/Multipurpose Internet Mail Extensions) is another email encryption standard but does not implement OpenPGP.

C. SMTP (Simple Mail Transfer Protocol) is a mail transport protocol, not an encryption method.

===========

Fileless malware can easily evade various security controls, organizations need to focus on monitoring, detecting, and preventing malicious activities instead of using traditional approaches such as scanning for malware through file signatures.Also known as non-malware, infects legitimate software, applications, and other protocols existing in the system to perform various malicious activities.It resides in the system’s RAM. It injects malicious code into the running processes. (P.966/950)
