ECCouncil 312-50v13 Exam With Confidence Using Practice Dumps

CEH v13 stresses the importance of passive reconnaissance when the goal is to avoid any interaction with the target’s systems. Job postings frequently reveal detailed information such as internal technologies, OS platforms, security tools, IDS brands, virtualization environments, scripting languages, and cloud services. CEH explicitly notes job ads as one of the richest passive intelligence sources because organizations inadvertently disclose their tech stack, often mentioning required experience with specific network components, databases, protocols, or internal tools. Options B and D involve direct interaction, violating the passive reconnaissance requirement. WHOIS lookups (Option C) provide DNS registrar information but do not reveal internal network details. Job postings, social media recruitment materials, and HR documentation are discussed in CEH as critical OSINT resources used during the footprinting phase to gather actionable intelligence while maintaining complete stealth. Thus, analyzing job postings is the correct method.

The TCP SYN scan, also known as a Stealth Scan, is emphasized in CEH v13 Network Scanning as the most effective balance between accuracy and stealth. It sends a SYN packet and analyzes the response without completing the TCP handshake.

Because the connection is never fully established, SYN scans are less likely to be logged by applications and are harder for IDS systems to detect compared to TCP Connect scans.

FIN and ACK scans are used for firewall rule mapping and evasion, but they do not reliably enumerate services. TCP Connect scans are noisy and easily detected. Therefore, Stealth (SYN) Scan is the best choice.

SMS Phishing, commonly called smishing, is the correct answer because the attack method is a deceptive text message sent to mobile devices that lures recipients into clicking a malicious link. In CEH-aligned social engineering coverage, smishing is a direct extension of phishing that uses SMS as the delivery channel. The attacker typically creates urgency or authority, such as “critical account update needed,” to trigger fast compliance. The message then pushes the victim to a malicious URL that can deliver malware, prompt credential entry, or enroll the device into a monitoring or management profile depending on platform and permissions. The key indicators in the question are company phones, a crafted message, and a link that installs monitoring software, which fits smishing exactly.

Bluebugging is a Bluetooth-based attack where the attacker exploits Bluetooth weaknesses to gain unauthorized access to a device, read data, place calls, or send messages, and it does not rely on sending a deceptive SMS link. Call spoofing is manipulating caller ID to impersonate a trusted number during voice calls, not delivering a malicious installation link through text. OTP hijacking focuses on intercepting or tricking users into revealing one-time passwords, often through SIM swapping, malware, or real-time phishing, but the scenario emphasizes installing monitoring software through a link rather than capturing a one-time code.

Defenses highlighted in ethical security training include mobile security awareness, blocking unknown links, using mobile threat defense, restricting app installation from untrusted sources, enforcing MDM controls, and monitoring SMS-based social engineering indicators.
