CEH v13 describes relay attacks as credential forwarding techniques where attackers trick systems into authenticating to malicious servers, capturing hashes, and relaying them to privileged services. The described scenario aligns exactly with the PetitPotam attack, a known MS-EFSRPC abuse method that forces Windows domain controllers to perform NTLM authentication to attacker-controlled hosts. CEH discusses how relay attacks combined with Active Directory Certificate Services (AD CS) misconfigurations can allow attackers to request privileged certificates, effectively gaining domain administrator privileges without cracking hashes or accessing LSASS. CRIME (Option B) targets TLS compression and is unrelated. Browser token theft (Option C) applies to web sessions, not domain controllers. Session donation (Option D) is not part of Windows authentication hijacking. Thus, the scenario clearly represents a PetitPotam NTLM relay attack.

The correct answer is C. Whois lookup because the scenario describes retrieving publicly available domain registration records using an online service without directly interacting with the target organization’s infrastructure. In CEH-aligned reconnaissance (footprinting) techniques, WHOIS is a foundational passive information-gathering method used to identify details tied to a domain name, such as the registrant/organization, administrative and technical contacts, registration and expiration dates, and the authoritative name servers associated with the domain. These details are commonly used to establish ownership context, map the organization’s external footprint, and identify potential points of contact for administrative or security coordination.

The prompt emphasizes that the ethical hacker wants “details about the organization’s domain ownership” and “points of contact.” That is precisely the kind of information WHOIS is intended to provide. It also explicitly notes “without direct interaction with the target,” which aligns with WHOIS being passive: queries are made to registries/registrars or WHOIS aggregation services rather than probing the target’s servers.

Why the other options are less correct: Email footprinting focuses on collecting email addresses, formats, mail servers, and potentially related metadata, but it is not the primary method for domain ownership/registrant contact records. Network footprinting is broader and often involves identifying IP ranges, network blocks, technologies, and topology—potentially including active probing. DNS interrogation (such as querying A, MX, NS, TXT records) can reveal technical DNS data and infrastructure mapping, but it typically does not provide the domain’s registrant ownership details and formal contact records; that role is handled by WHOIS and registry data.

Therefore, the method most likely used here is a WHOIS lookup to obtain public domain registration and contact information.

CEH categorizes spear phishing as a highly targeted, research-driven social engineering technique that tailors the message to the victim’s role, responsibilities, and current organizational activities. When attackers reference specific internal projects, personnel names, vendor relationships, or operational details, the message appears authentic and bypasses normal suspicion. Executives are especially vulnerable because they routinely receive sensitive operational updates and work closely with vendors and partners, making them prime targets for tailored deception. CEH stresses that spear phishing is significantly more effective than generic phishing because personalization increases trust. Social media-based attempts and mass phishing lack specificity and raise suspicion. Impersonating the CEO over the phone is riskier and more detectable due to real-time human interaction. A targeted spear-phishing email referencing internal projects best aligns with CEH-described advanced social engineering strategy.

The correct answer is C, Preparation. In the incident response lifecycle, preparation is the stage performed before an actual incident occurs. This phase focuses on making the organization ready to respond effectively by creating the incident response plan, forming the incident response team, assigning roles and responsibilities, defining escalation paths, and testing communication procedures. CEH incident management material lists “Preparation for Incident Response” as the first incident response process before detection, classification, notification, containment, investigation, eradication, recovery, and post-incident activities. It also emphasizes setting up an incident response team, identifying the people who should be contacted during an intrusion, and defining lines of communication. Containment occurs after an incident is detected and aims to limit damage. Notification involves informing affected users or stakeholders. Recovery restores affected systems to normal operation. Since building the team and testing communication happen before an incident, the correct phase is Preparation.
