Wireshark is the primary packet-sniffing tool covered in CEH v13 Network Sniffing. It captures and analyzes live traffic, allowing analysts to view plaintext HTTP packets.

Nessus is a vulnerability scanner, Nmap is for scanning, Netcat is a networking utility. None provide protocol-level inspection like Wireshark.

Thus, Option D is correct.

The Certified Ethical Hacker (CEH) Incident Response lifecycle begins with Identification, followed by containment, eradication, recovery, and lessons learned. CEH documentation stresses that understanding the scope and nature of an incident is critical before taking disruptive action.

Option A is the correct initial response because it focuses on real-time monitoring and log analysis, which are essential during the identification phase. CEH materials emphasize analyzing logs, authentication failures, and traffic anomalies to confirm whether an incident has occurred and determine the attacker’s techniques, persistence level, and impact.

Option B, while valuable, is more appropriate after initial identification. Conducting deep outbound traffic audits without first understanding the attack vector can delay containment decisions.

Option C is premature. CEH warns that changing credentials too early may alert the attacker and cause them to escalate or destroy evidence.

Option D represents a containment strategy, not an initial response. CEH guidelines advise against immediately disconnecting systems unless there is confirmed active data exfiltration that cannot be otherwise controlled, as this may disrupt business operations and erase volatile forensic evidence.

Therefore, the CEH-approved approach is to monitor, analyze, and identify the incident before moving to containment and eradication.

CEH materials describe this attack pattern as Living-off-the-Land (LotL), where attackers abuse legitimate tools to avoid detection. Because these binaries are normally trusted, traditional antivirus solutions may not flag them.

CEH recommends file integrity monitoring (FIM), which tracks cryptographic hashes of sensitive executables and alerts administrators when unauthorized modifications occur.

Option D is correct.

Options A and B support resilience but do not detect tampering.

Option C alone is insufficient against LotL attacks.

The CEH SQL Injection module defines stacked (piggybacked) queries as attacks where an attacker appends an additional SQL statement using a statement delimiter such as a semicolon.

In this scenario, the attacker executed a second query (DROP TABLE users) after the original query, resulting in destructive behavior.

Option B is correct.

Option A retrieves data, not execute destructive commands.

Option C infers logic outcomes.

Option D relies on error messages for data extraction.

CEH classifies stacked queries as high-impact SQL injection attacks.
