312-50v13 Exam Dumps - Certified Ethical Hacker Exam (CEHv13)

CEH describes FIN scans as stealthy scans that send packets with the FIN flag without initiating a TCP handshake. According to TCP RFC behavior, closed ports respond with RST packets while open ports ignore the probe, producing no response. This allows enumeration of port states while evading IDS systems that typically monitor SYN-based scans.

Zero-day exploits are considered the most dangerous mobile attack vector in CEH v13 Mobile Platform Hacking. These exploits abuse previously unknown vulnerabilities, meaning no patches, signatures, or defenses exist at the time of attack.

In healthcare environments, mobile devices access sensitive EHR systems and operate under strict compliance requirements. Zero-day exploits can bypass mobile OS security, sandboxing, and antivirus controls entirely.

App spoofing and Bluejacking are easier to detect and mitigate through user awareness and Bluetooth controls. Side-channel attacks are highly specialized and rare in enterprise mobile environments.

CEH v13 stresses that zero-day attacks pose the greatest risk due to lack of detection mechanisms, making Option A correct.

In CEH v13 Reconnaissance and Enumeration, NetBIOS name suffixes are used to identify the role of systems within a Windows network. The <1B> NetBIOS suffix is particularly significant because it uniquely identifies the Domain Master Browser, which in modern Windows environments corresponds to the Primary Domain Controller (PDC).

When an nbtscan is performed, multiple systems may respond with NetBIOS names, but only one system per domain will register the <1B> suffix. This is because the PDC is responsible for maintaining the master browse list and coordinating authentication services across the domain.

Option C is correct because the <1B> entry is explicitly defined in CEH documentation as belonging to the domain controller.

Option A is incorrect because the local system does not advertise <1B>.

Option B is incorrect because DHCP servers use different identifiers and do not register <1B>.

Option D is incorrect because NetBIOS must be enabled for <1B> to appear at all.

CEH v13 highlights identifying <1B> during enumeration as a high-value discovery, since domain controllers are prime targets during privilege escalation and lateral movement phases.

The purpose of this idea is to permit multiple customers to figure on joint projects and applications that belong to the community, where it’s necessary to possess a centralized clouds infrastructure. In other words, Community Cloud may be a distributed infrastructure that solves the precise problems with business sectors by integrating the services provided by differing types of clouds solutions.

The communities involved in these projects, like tenders, business organizations, and research companies, specialise in similar issues in their cloud interactions. Their shared interests may include concepts and policies associated with security and compliance considerations, and therefore the goals of the project also .

Community Cloud computing facilitates its users to spot and analyze their business demands better. Community Clouds could also be hosted during a data center, owned by one among the tenants, or by a third-party cloud services provider and may be either on-site or off-site.

Community Cloud Examples and Use Cases

Cloud providers have developed Community Cloud offerings, and a few organizations are already seeing the advantages . the subsequent list shows a number of the most scenarios of the Community Cloud model that’s beneficial to the participating organizations.

Multiple governmental departments that perform transactions with each other can have their processing systems on shared infrastructure. This setup makes it cost-effective to the tenants, and may also reduce their data traffic.

Benefits of Community Clouds

Community Cloud provides benefits to organizations within the community, individually also as collectively. Organizations don’t need to worry about the safety concerns linked with Public Cloud due to the closed user group.

This recent cloud computing model has great potential for businesses seeking cost-effective cloud services to collaborate on joint projects, because it comes with multiple advantages.

Openness and Impartiality

Community Clouds are open systems, and that they remove the dependency organizations wear cloud service providers. Organizations are able to do many benefits while avoiding the disadvantages of both public and personal clouds.

Flexibility and Scalability

Ensures compatibility among each of its users, allowing them to switch properties consistent with their individual use cases. They also enable companies to interact with their remote employees and support the utilization of various devices, be it a smartphone or a tablet. This makes this sort of cloud solution more flexible to users’ demands.

Consists of a community of users and, as such, is scalable in several aspects like hardware resources, services, and manpower. It takes under consideration demand growth, and you simply need to increase the user-base.

High Availability and Reliability

Your cloud service must be ready to make sure the availability of knowledge and applications in the least times. Community Clouds secure your data within the same way as the other cloud service, by replicating data and applications in multiple secure locations to guard them from unforeseen circumstances.

Cloud possesses redundant infrastructure to form sure data is out there whenever and wherever you would like it. High availability and reliability are critical concerns for any sort of cloud solution.

Security and Compliance

Two significant concerns discussed when organizations believe cloud computing are data security and compliance with relevant regulatory authorities. Compromising each other’s data security isn’t profitable to anyone during a Community Cloud.

Users can configure various levels of security for his or her data. Common use cases:

the power to dam users from editing and downloading specific datasets.

Making sensitive data subject to strict regulations on who has access to Sharing sensitive data unique to a specific organization would bring harm to all or any the members involved.

What devices can store sensitive data.

Convenience and Control

Conflicts associated with convenience and control don’t arise during a Community Cloud. Democracy may be a crucial factor the Community Cloud offers as all tenants share and own the infrastructure and make decisions collaboratively. This setup allows organizations to possess their data closer to them while avoiding the complexities of a personal Cloud.

Less Work for the IT Department

Having data, applications, and systems within the cloud means you are doing not need to manage them entirely. This convenience eliminates the necessity for tenants to use extra human resources to manage the system. Even during a self-managed solution, the work is split among the participating organizations.

Environment Sustainability

In the Community Cloud, organizations use one platform for all their needs, which dissuades them from investing in separate cloud facilities. This shift introduces a symbiotic relationship between broadening and shrinking the utilization of cloud among clients. With the reduction of organizations using different clouds, resources are used more efficiently, thus resulting in a smaller carbon footprint.

The command C. Hping3 -S 192.168.1.1 -a 192.168.1.254 -p 22 -flood is the correct one to spoof IP addresses for anonymity during probing. This command sends SYN packets (-S) to the target IP 192.168.1.1 with a spoofed source IP (-a) 192.168.1.254 on port 22 (-p) and floods the target with packets (-flood). This way, the CEH can hide his real IP address and avoid detection by the target’s firewall or IDS12.

The other commands are incorrect for the following reasons:

A. Hping3 -110.0.0.25 --ICMP: This command sends ICMP packets (–ICMP) to the target IP 10.0.0.25, but does not spoof the source IP. Therefore, the CEH’s real IP address will be exposed to the target.

B. Nmap -sS -Pn -n -vw --packet-trace -p- --script discovery -T4: This command performs a stealthy SYN scan (-sS) on all ports (-p-) of the target without pinging it (-Pn) or resolving DNS names (-n). It also enables verbose output (-v), packet tracing (–packet-trace), and discovery scripts (–script discovery) with an aggressive timing (-T4). However, this command does not spoof the source IP, and in fact, reveals more information about the scan to the target by using packet tracing and discovery scripts.

D. Hping3-210.0.0.25-p 80: This command sends TCP packets (default) to the target IP 10.0.0.25 on port 80 (-p), but does not spoof the source IP. Therefore, the CEH’s real IP address will be exposed to the target.

CEH v13 explains that a keylogger is a type of spyware designed to capture user input covertly, often storing or transmitting captured data—such as passwords, emails, chat messages, and financial information—to an attacker. Keyloggers can be implemented as software, firmware, or hardware, and they operate silently in the background without affecting system performance, making them ideal for credential theft. CEH categorizes keyloggers under spying and monitoring malware frequently used in the System Hacking phase to escalate privileges or move laterally once credentials are harvested. Unlike rootkits, which hide processes, or ransomware, which encrypts files, a keylogger’s main purpose is passive surveillance. CEH emphasizes how attackers deploy keyloggers post-compromise or use phishing/social engineering to trick victims into installing them. Their covert nature and ability to bypass traditional AV solutions by masquerading as legitimate processes make identifying them crucial during forensics and incident response activities.

The CEH Enumeration module explains that SMTP supports commands such as VRFY, EXPN, and RCPT TO, which can be abused to enumerate valid email users if not properly restricted.

In this scenario, the smtp-enum-users Nmap script successfully uses EXPN and RCPT, indicating that the server responds differently to valid and invalid usernames.

Option C is correct because unrestricted SMTP user verification allows attackers to harvest usernames for further attacks such as phishing or brute force.

Option A involves authentication, not enumeration.

Option B affects confidentiality, not user discovery.

Option D is unrelated to SMTP enumeration.

CEH strongly recommends disabling or restricting these SMTP commands.

An untethered jailbreak is one that allows a telephone to finish a boot cycle when being pwned with none interruption to jailbreak-oriented practicality.

Untethered jailbreaks area unit the foremost sought-after of all, however they’re additionally the foremost difficult to attain due to the powerful exploits and organic process talent they need. associate unbound jailbreak is sent over a physical USB cable association to a laptop or directly on the device itself by approach of associate application-based exploit, like a web site in campaign.

Upon running associate unbound jailbreak, you’ll be able to flip your pwned telephone off and on once more while not running the jailbreak tool once more. all of your jailbreak tweaks and apps would then continue in operation with none user intervention necessary.

It’s been an extended time since IOS has gotten the unbound jailbreak treatment. the foremost recent example was the computer-based Pangu break, that supported most handsets that ran IOS nine.1. We’ve additionally witnessed associate unbound jailbreak within the kind of JailbreakMe, that allowed users to pwn their handsets directly from the mobile campaign applications programme while not a laptop.
