312-50v13 Dumps With Exact Questions and Answers

CEH v13 details that fragmentation attacks are a common IDS evasion strategy. Signature-based IDS systems depend on reassembling packets to detect malicious patterns. When attackers fragment TCP headers into smaller segments, the IDS may be unable to reconstruct the original packet sequence, especially if the fragments are intentionally crafted to confuse reassembly buffers. Meanwhile, the target host typically recombines the fragments correctly, allowing the scan or payload to pass undetected. This technique is specifically discussed under IDS evasion methods, where fragmentation prevents complete packet inspection. Options A and B describe unrelated evasion mechanisms such as IP spoofing and MAC spoofing, and Option C does not fundamentally affect IDS reconstruction. The tester is clearly using packet fragmentation to evade detection while still mapping open ports successfully.

In CEH v13 Module 17: Mobile and IoT Security, Advanced SMS Phishing (also known as SMiShing) is described as a technique where attackers impersonate trusted entities via SMS to:

Trick users into entering authentication codes or PINs.

Deliver malicious payloads or alter device configurations.

Simulate OTA (Over-the-Air) provisioning messages.

In this case:

The attacker sends a fake OTA setup message asking for a PIN.

Once Ben enters the PIN, the device's configuration is hijacked.

Why Others Are Incorrect:

B. Bypass SSL pinning: Relates to mobile app reverse engineering and traffic interception.

C. Phishing: General term; SMS-specific variant is more accurate here.

D. Tap ‘n ghost: A touch screen manipulation attack, unrelated to messaging.

Correct answer is A. Advanced SMS phishing.

In CEH v13 Module 01: Information Security Governance, PCI-DSS (Payment Card Industry Data Security Standard) is introduced as the mandatory compliance framework for organizations handling credit card transactions.

PCI-DSS Requirements Include:

Encrypting cardholder data.

Maintaining secure systems and applications.

Regular vulnerability testing and audits.

Restricting access to sensitive data.

Option Clarification:

A. FISMA: Applies to U.S. federal information systems.

B. HITECH: Related to health information privacy and HIPAA.

C. PCI-DSS: Correct for credit card companies and merchant environments.

D. SOX (Sarbanes-Oxley): Focuses on financial reporting, not card data.
