The tool described matches Fern WiFi Cracker because CEH wireless assessment workflows commonly reference GUI-based auditing utilities that combine packet capture, wireless injection support, and key recovery attempts in one interface. The scenario specifically mentions three core capabilities: capturing wireless packets, sending de-authentication frames to trigger client reconnects, and attempting to recover the encryption key. Those steps align with the typical WPA cracking methodology discussed in CEH learning paths: capture the WPA handshake when a client connects, optionally force a reconnection by sending de-authentication frames, then perform an offline attack against the captured handshake using a wordlist or brute-force approach. Fern WiFi Cracker is known for presenting these functions through a graphical interface, making it a common example of an “all-in-one” Wi-Fi auditing tool.

The other options are defensive monitoring and prevention platforms, not offensive auditing tools used to actively deauthenticate clients or attempt key recovery. RFProtect, Cisco Adaptive Wireless IPS, and WatchGuard Wi-Fi Cloud WIPS are Wireless Intrusion Prevention and Monitoring solutions designed to detect rogue access points, identify attacks such as deauthentication floods, enforce wireless security policies, and generate alerts for security teams. They are used to stop or respond to attacks rather than conduct packet capture plus key-recovery attempts as part of an assessment.

Because the question emphasizes a single graphical interface that captures traffic, injects deauth frames, and attempts key recovery, the correct match among the choices is Fern WiFi Cracker.

The correct answer is B. ARP Spoofing because the described outcome—silently redirecting traffic between two hosts through the attacker’s machine on a LAN without changing switch configurations—is the classic effect of ARP poisoning (also called ARP spoofing). In CEH-aligned network sniffing and man-in-the-middle (MITM) techniques, ARP spoofing works by sending forged ARP replies onto the local network so that a victim host associates the attacker’s MAC address with the IP address of a legitimate system (commonly the default gateway or another target host). Once the victim’s ARP cache is poisoned, frames intended for the real destination are instead sent to the attacker, who can then forward them to the legitimate host to maintain connectivity while inspecting or altering the traffic.

The scenario states David “injects crafted messages” and then “all traffic between a finance workstation and the authentication server is silently routed through his system.” That behavior strongly indicates ARP spoofing performed in both directions: poisoning the workstation to believe the attacker is the authentication server (or gateway) and poisoning the server to believe the attacker is the workstation (or gateway). This enables a transparent MITM position where credentials can be observed—especially if protocols are unencrypted or if the attacker can downgrade or strip protections. The fact that “no proxy or VPN is in use” supports the idea that the redirection is happening at Layer 2/Layer 3 on the local segment rather than via an explicit application-level proxy.

Why the other options are less accurate: Switch port stealing targets switch CAM tables to redirect frames, but it is less directly described than ARP cache poisoning between two IP endpoints. An STP attack manipulates spanning tree to become the root bridge and can influence paths, but it is a different control-plane attack and usually affects broader Layer 2 topology. IRDP spoofing involves ICMP Router Discovery Protocol to advertise a rogue router, but the scenario fits the much more common and direct MITM sniffing technique on a switched LAN: ARP spoofing.

Therefore, David most likely used ARP spoofing.

CEH v13 describes Cross-Site Request Forgery (CSRF) as a technique that forces authenticated users to unknowingly execute actions within a web application without their intent. Unlike session hijacking methods that require stealing or replaying session cookies, CSRF exploits the trust relationship that the server has with a user's browser. Even with HTTPS, secure cookies, and MFA, once a user is authenticated, the browser automatically sends session cookies with each request. If the attacker convinces the victim to load a maliciously crafted webpage or URL, the browser sends a forged request to the target application, executing actions under the user’s authenticated session. CEH notes that secure cookies and MFA do not stop CSRF because no credentials are stolen—only forced actions occur. This technique is sophisticated because it leaves minimal traces, avoids direct cookie manipulation, bypasses robust authentication mechanisms, and leverages design weaknesses rather than technical misconfigurations. Protection typically requires anti-CSRF tokens and proper origin validation.

CEH v13 defines passive reconnaissance as information gathering without interacting directly with the target or alerting them. The goal is to remain undetected while collecting intelligence from publicly available sources.

Directly interacting with a threat actor on forums—even under a pseudonym—constitutes active engagement. CEH v13 warns that such interaction risks exposure, attribution, and legal complications. It can alert the adversary, cause them to alter behavior, or even retaliate.

WHOIS lookups, DNS queries, archived web content, and anonymous browsing are all passive techniques endorsed in CEH v13. These methods do not notify the target and leave minimal trace.

Thus, Option A should be avoided to maintain a low profile.
