When standard protections such as HTTPS, HTTP-only flags, and session regeneration are properly implemented, CEH teaches that predictable session identifiers become one of the few remaining avenues for session hijacking. Session token prediction involves analyzing entropy, randomness, or generation patterns within session IDs to mathematically infer future or valid tokens. If the application uses weak randomization algorithms, insufficient entropy sources, or predictable sequences, attackers may generate a valid session ID without direct interception. Techniques such as MitM interception or CSRF manipulation do not bypass strong transport-layer protections and cookie restrictions. Session fixation fails because the application regenerates the session ID upon login, invalidating pre-set identifiers. Therefore, the advanced and CEH- aligned method to hijack a protected session is predicting session IDs through side-channel or pattern analysis.

A Wireless Intrusion Prevention System (WIPS) is a network device that monitors the radio spectrum for the presence of unauthorized access points (intrusion detection), and can automatically take countermeasures (intrusion prevention).

Whois footprinting is a reconnaissance technique used by attackers and penetration testers to gather publicly available information about domain names. By performing a Whois lookup, one can retrieve:
* Domain registrant details (name, email, phone, and address)
* Domain registration and expiry dates
* Name servers and registrar information
* Administrative and technical contact data
According to CEH v13:
* Whois databases are maintained by Internet registrars and can be queried through tools like whois lookup or websites such as https://whois.domaintools.com.
* This information helps attackers build a profile of the organization, identify potential social engineering targets, and even understand domain structure for further attacks.
Incorrect Options:
* A. VPN footprinting refers to identifying VPN gateways or configurations - not related to domain data.
* B. Email footprinting involves gathering information from or about email systems.
* C. VoIP footprinting targets IP-based telephony systems, such as SIP endpoints.

Syslog messages are typically sent over UDP or TCP port 514 to the Syslog server. In this case, Snort (192.168.0.99) should send alerts to Kiwi Syslog (192.168.0.150) using TCP/UDP port 514.
The correct Wireshark filter to check if Snort is sending the messages to the Syslog server is:
tcp.dstport==514 && ip.dst==192.168.0.150

Module 8: Sniffing
Topic: Packet Sniffing and Analysis
Quote:
"Wireshark filters like tcp.dstport and ip.dst can be used to verify outbound logs and traffic from intrusion detection systems." Incorrect Options:
A & B: Use incorrect IP addresses or direction
C: Uses incorrect destination IP (should be the Syslog server)

The virus described changes its own code with each execution but still performs the same actions. This is the hallmark of a Metamorphic Virus. Unlike polymorphic viruses (which use encrypted code with a changing decryptor), metamorphic viruses rewrite their own code entirely - including their decryption and execution routines - to avoid pattern detection by antivirus software.
Key characteristics of metamorphic viruses seen in the scenario:
Mutates completely on every execution.
Keeps overall functionality identical (semantics intact).
Alters its appearance and logic flow.
From CEH v13 Courseware:
Module 6: Malware Threats # Types of Viruses and Obfuscation Techniques CEH v13 Study Guide states:
"Metamorphic viruses modify their own code structure and appearance with each iteration, without altering their underlying behavior. This makes them more difficult to detect through signature-based mechanisms." Incorrect Options:
A: Polymorphic viruses encrypt themselves with a changing decryptor stub but do not change their core logic.
C: "Dravidic Virus" is not a recognized term in cybersecurity.
D: Stealth viruses hide their presence (e.g., by intercepting system calls), but do not change their code structure.
