ECCouncil Updated 312-50v13 Exam Questions and Answers by emmy

CEH v13 explains that WPA2-PSK security relies on the strength of the pre-shared key. Once the 4-way handshake is captured, the attacker must attempt offline cracking. CEH emphasizes that the dictionary attack is the most efficient and commonly used cracking method because it tests structured wordlists, human-derived passwords, and hybrid permutations, dramatically reducing time compared to full brute force. Brute forcing (Option B) is computationally heavy and often impractical unless the password is extremely short. XSS (Option A) and SQL injection (Option D) have no relevance to WPA2 authentication, which occurs at the wireless protocol level, not the router’s web interface. The dictionary attack is highlighted in CEH as the principal technique used with tools like aircrack-ng, hashcat, and pyrit, allowing rapid key testing using optimized GPU or CPU cracking. Thus, Option C is the most effective and CEH-aligned method.

The CEH Mobile Platform Security module explains that mobile antivirus solutions rely heavily on signatures and known exploit patterns. A custom exploit with obfuscation is far more likely to bypass detection.

CEH explicitly teaches that:

Zero-day or unpatched vulnerabilities

Custom, obfuscated payloads

Minimal use of known frameworks

are the most effective for bypassing endpoint defenses during controlled testing.

Option A is correct.

Options B and C are easily detected.

Option D is social engineering, not a technical exploit.

CEH v13 classifies this malware as fileless malware, which resides in memory and abuses legitimate system tools (Living-off-the-Land techniques). Traditional antivirus solutions are often ineffective.

CEH v13 recommends:

Script control (PowerShell Constrained Language Mode)

Application whitelisting

Monitoring parent-child process relationships

These measures directly target the malware’s execution method. Reboots and folder cleanup do not address in-memory persistence.

Network Access Control (NAC) solutions often authenticate only the first device connected to a port. CEH explains that attackers can insert a rogue device behind an already authenticated host, bypassing NAC checks. This creates a transparent bridge that forwards legitimate traffic while injecting attacker-controlled communications.
