Ethical Hacking Interview Questions And Answers

I know you’ve done your research and read through a bunch of the websites about ethical hacking but want to be sure that you can answer any question on the real ethical hacking interview. Good news! We have an entire blog dedicated to answering these questions. Please read through this blog and see if there is any question that you may have previous questions regarding.

1. What is Ethical Hacking?

Ethical hacking is the practice of testing a computer, network or system for security vulnerabilities. It can be used to help an organization discover security flaws in their systems prior to a data breach. Ethical hackers are not connected with any malicious intent and they do not use their knowledge for personal gain. In some cases, ethical hackers are hired by businesses to test their systems for vulnerabilities that could lead to a data breach or loss of sensitive information. In other cases, ethical hackers work independently in order to assess the security of their own networks or those of others.

2. What Are Different Types of Virus?

• File-infecting Virus: The file-infecting virus is a type of computer program that infects files, or alters their content. The virus can be spread through email, floppy disks and other removable media. File-infecting viruses are often spread by attaching them to an email message. They do not have to be in the body of the message; they can simply be attached as an attachment. Once opened, the virus will replicate itself and infect any other files it encounters. File-infecting viruses are relatively easy to remove from a computer if detected early enough. By finding and removing all suspicious files before they can replicate themselves, you can prevent your system from becoming infected with a file-infecting virus!
•  Macro Virus: Macro Virus is a virus that is released on your computer whenever you open a document or an email from unknown sources. It will not only download and install malware, but also compromise the security of your system and make it vulnerable to other types of attacks.
• Browser Hijacker: Browser Hijacker is a type of malware that can be used to redirect your browser to unwanted websites and download malicious files onto your computer. Browser hijacker is a type of malware that can be used to redirect your browser to unwanted websites and download malicious files onto your computer. Browser hijackers are often distributed via spam emails, peer-to-peer networks, and compromised websites. Some browser hijackers may also be downloaded from unsafe software distribution sites. Browser hijackers are not always malicious. However, if you have an infected computer, it might be possible for cybercriminals to use it to spy on you or launch more advanced attacks in the future.
•  Web Scripting Virus: Web Scripting Virus is a computer virus that infects the web browser, causing it to display fake or fraudulent websites on the user’s screen. The virus often displays pop-up windows with ads for programs or websites. Web Scripting Virus can also change your browser settings, like adding extensions and changing default search engines. Web Scripting Virus is a type of browser hijacker that can be downloaded from malicious websites to your computer without your permission. This infection then starts displaying fake or fraudulent websites on your screen and will change your browser’s settings so that you’re redirected to these bogus sites every time you open up a website. Web Scripting Virus was first discovered in May 2019 by security researchers at Trend Micro after it had already infected millions of computers worldwide. The infection was spread through social media platforms such as Facebook, Twitter, Instagram and Pinterest where users are frequently targeted with fake advertisements related to products or services they have never even heard about before.
• Boot Sector Virus: A Boot Sector virus is a virus that infects the boot sector of a hard disk. The boot sector is a tiny area of the hard disk that contains information about the entire computer such as the drive’s partition table and its BIOS settings. The virus then spreads by copying itself to other parts of the hard drive and by modifying or deleting specific files or directories.
• Resident Virus: The Resident Virus is a computer virus that spreads slowly and silently, infecting new computers in the same way as other viruses. It is not detected by antivirus programs as it doesn’t appear in the system scans. The virus infects files and then downloads itself to other systems. The Resident Virus does not attack any of your programs or data but instead installs itself on your system and then waits for other systems to download it. This means that no matter how many times you delete the Resident Virus, it will always re-infect another computer on which you run a program that has been infected with the Resident Virus.
• Multipartite Virus: Multipartite computer Virus is a type of computer virus that can infect multiple files in your system. The virus does not just limit itself to one file but infects multiple files. This is the most dangerous part about it because the virus can spread from one file to another, causing chaos and trouble for you. Multipartite computer Virus is very dangerous, especially when it comes to your personal information. It can steal your personal data and use it for illegal activities, like identity theft or credit card fraud.

• Boot Sector Virus: Boot Sector Virus is a type of virus that infects your computer’s boot sector, or Master Boot Record. The Master Boot Record is the part of your hard drive that contains information about your operating system and other programs. The boot sector virus infects your computer by installing itself into the Master Boot Record, which then allows it to continue to infect other areas of your hard drive. This is what makes it so dangerous once it has infected the Master Boot Record, there’s nothing you can do to get rid of it.
• Direct Action Virus: The Direct Action Virus is a complex computer virus that has been spreading throughout the world. Its purpose is to corrupt data and make it difficult for anyone to access anything on the internet. The virus was designed by an unknown hacker who goes by the name of “Mr. X.” He created this virus with the intent of spreading it to as many people as possible. The virus uses two methods to spread itself: it spreads itself through email and then infects computers when users click on links or open attachments sent from other infected users. 66Once a person becomes infected with this virus, their computer will begin sending out thousands of emails every minute with links that lead back to sites where you can download malware or other types of viruses. These links can contain malicious code or even just ads for various products that are owned by Mr. X himself!
• Overwrite Virus: Overwrite Virus is a new form of computer virus that overwrites files with random data. The virus was discovered by security researchers from Proofpoint in October 2018. It has been spreading since then and can affect personal computers on Windows, Mac OS X, Linux and Chrome OS operating systems. Overwrite Virus is designed to spread from one computer to another by exploiting vulnerabilities in the operating systems of the target machines. This type of malware has been around for years but it has changed its tactics over time by hiding itself within legitimate files sent through email or shared through social media platforms like Facebook and Twitter.
• Polymorphic Virus: The Polymorphic Computer Virus (PCV) is a malware that uses stealth techniques to evade detection by anti-virus software. It can be spread through removable media and email attachments. PCV is distributed in many different ways, including peer-to-peer (P2P) networks, drive-by downloads, spam messages and infected websites. If an infected computer is connected to the Internet, the virus can download additional malware onto it. Although there are several variations of PCV, they all share common characteristics: they have several components that work together to infect users’ computers; they use encryption to hide their source; they’re difficult to detect and remove; and they can spread from one infected computer to another.
• File Infector Virus: File Infector Virus is a computer virus that infects files. Once it has infected a file, it modifies the content of the file and then appends it to another file. File Infector Virus can also be used to modify the “root” folder of an infected computer so that when users try to open files, they are redirected to malicious websites. This computer virus is capable of replicating itself in many ways. It can replicate itself by copying itself onto other files, by copying itself onto the same file multiple times, or by creating copies of itself within other corrupted files. File Infector Virus is one of many viruses that have been reported over the past few years. It is typically spread through email messages and attachments or downloads from websites infected with malware.
• Spacefiller Virus: The Spacefiller Virus is a highly contagious computer virus that spreads through files. The Spacefiller Virus infects files stored on any type of computer, including laptops and desktops. As long as there are still files on the infected machine, the Spacefiller Virus can continue to spread. The most common way that the Spacefiller Virus spreads is by email or instant messaging (IM). When an infected file is sent via email or IM, it can infect other computers through the same means. If you receive an infected file by email or IM, it’s very important to scan your computer immediately with a reliable anti-virus application in order to remove the virus from your system.
• Macro Virus: Macro Virus is a type of malicious code that can infect your computer and make it act in some abnormal way. It usually comes disguised as an email attachment, but it can also be a file that is sent by an infected website. Macro viruses are often used to steal sensitive information from your computer or take control over it.

3. What is the Difference between Ping and Net Send?

Ping and net send are not the same thing. Ping is a basic network tool that allows you to see how long it takes for data to travel from your computer to another computer on the same network. Net send is a command that allows you to transfer files or commands between two computers on a network. Ping uses ICMP (Internet Control Message Protocol) packets, while net send uses TCP/IP connections. Ping is used to test the reachability of another host, while net send is used to transfer data among two hosts on the same local area network (LAN).

4. What is NAT?

NAT stands for Network Address Translation. A NAT router is a router that can do two things: connect two private networks together, and translate private IP addresses to public IP addresses. NAT is a way of allowing multiple devices on a single network to use the same public IP address while maintaining privacy and security between those devices. It’s often used by large organizations with hundreds or thousands of computers on a network that need to share an IP address.

5. What is IDS?

IDS stand for Intrusion Detection System. This is a set of tools that can detect malicious activity on your network or servers. There are many different types of IDSs, including Network IDS, Host-based IDS, Application Level IDS and even Web-based or Cloud based IDS. IDSs have been around for many years now and have made great strides in improving their detection rates. However, with the rise of new technologies such as cloud computing and mobile devices, security professionals are looking for ways to make their systems more efficient and effective.

6. What is Map Drive in a Computer Network?

Map drive is a term used to describe the method by which a computer network controller communicates with its attached devices. The controller, also known as a server, is responsible for managing all network traffic and assigning network addresses to each device that connects to the network. The process of mapping drives involves sending messages from the server to each device on the network asking it what type of data it wants to receive or transmit. The server then sends this information down to the appropriate devices, which then send back their responses back up through their own connections to the server.

7. What Are the Types of DNS Servers Available in the Market?

The most common types of DNS servers include:

Primary DNS Server: These are usually the first or top-level DNS servers in a network. They are responsible for resolving queries from devices that have IP addresses, such as computers and smartphones. An example would be Google Public DNS and Open DNS.

Secondary DNS Server: This type of DNS server is used to resolve queries for subnetworks such as a LAN-to-LAN connection. These secondary servers also act as gateways for other client devices on the same subnet. On the other hand, primary and secondary servers can be combined into a single device called a load balancer or load distributor.

Global Secondary DNS (GSDN): This type of secondary server is often used within private networks that cannot afford to buy their own public IP address space but want to offer public access to their services via the Internet. GSDNs use Internet Protocol version 6 (IPv6) addresses instead of IPv4 addresses because they are more secure and easier to manage than IPv4 traffic.

8. Explain About E-Mail Spoofing:

E-mail spoofing is the practice of sending e-mail messages that appear to originate from someone other than the sender. Companies and individuals can be victim to this type of fraud, as it is a form of telemarketing fraud. A company may be sending out a mass mailing to potential customers and end up receiving a lot more spam than they intended. This could result in lost revenue and negative publicity for the company. E-mail spoofing has become an issue because it not only affects businesses but also consumers. Consumers can be tricked into clicking links that take them to fraudulent websites where they may lose their financial information or personal information.

9. What is the Difference between an Ethical Hacker and a Cracker?

An ethical hacker is a skilled computer professional who specializes in hacking into computer systems and gathering information to find security vulnerabilities. Crackers use brute force and other methods to break into computers. Crackers are often referred to as white hat hackers, while ethical hackers are sometimes called black hat hackers because they use their skills for good rather than evil.

10. What are the Types of Hackers?

Hackers can be divided into three main categories:

White Hat Hackers are ethical hackers, who use their skills to help companies secure their information and systems. They may publish their findings and solutions to vulnerabilities.

Black Hat Hackers are malicious hackers, who use their skills to steal information or cause damage.

Gray Hat Hackers are the middle ground between black hats and white hats. They may use illegal methods for financial gain, but not for personal gain.

11. Who is a Script Kiddie?

A script kiddie is someone who uses scripts to perform activities on the Internet. The term has been used primarily in relation to computer hacking, but it has found its way into other fields as well. Script kiddies are people who use scripts for a number of different reasons. Script kiddies can be motivated by a variety of different motivations. Some of them may have a desire to become internet gurus or hackers, while others may just want to impress friends and family members with their computer skills. Some might simply enjoy playing around with computers and learning how they work. Whatever the reason, if you’re looking for a script kiddie script download, we’ve got you covered!

12. Name Some Hacking Attacks:

Buffer Overflow Attack: This type of attack involves sending special instructions to the computer’s memory that cause it to overflow, which makes it crash or give access to the attacker. The instructions must be entered by a hacker in order for this type of attack to work.

Social Engineering – This is an attack in which someone tricks you into giving away personal information such as your name and address by pretending to be someone else.

Denial of Service (DDoS) Attack – This is an attack that causes your device to overload and crash. It’s intended to bring down websites and other online services so that the hacker can take control over them.

SQL Injection Attack: This attack is carried out when a hacker or hacker uses a software bug to enter malicious commands into the database. The hacker can access information from other users’ accounts, change passwords, and create new user accounts.

Privilege Escalation Attack: A privilege escalation attack occurs when an attacker gains unauthorized access to a system or network by exploiting a common weakness in that system or network. For example, many systems allow an administrator user account with full privileges to perform administrative tasks on all computers in a network. An attacker can take advantage of this weakness by gaining access to one computer and then moving laterally across the network until they find another vulnerable computer that has no security measures protecting it from outside access.

13. Which Language is mostly used by Hackers to Type Their Code?

In the last few years, there has been a growth in the number of hackers. The main reason for this is that computers have become more powerful, and hence, hackers can make their work easier by using a computer. The most common language used by hackers is C++. It is because it is easy to use and understand for beginners. C++ is also known as object-oriented programming language, which means that it deals with objects rather than just numbers or text strings.

14. Why do Hackers use Linux?

Linux is the most popular operating system for hackers. Because it’s free open source and easy to use. The main reason why hackers prefer Linux over any other operating system is because it’s free. There are many different versions of Linux available on the internet, so hackers can try them all without spending any money on them. Another reason why hackers prefer Linux over other operating systems is that it’s open source. If a hacker wants to download a program for their computer or phone, they will have to get permission from its creator first before doing so. However, by using an open source program there is no need for the creator’s permission because anyone can download the program and use it as long as they pay for it (or copy it).

15. What is a BotNet or a Zombie Army?

The term “botnet” is a loose term for a network of compromised computers that are used to send spam or launch other attacks. A botnet often consists of infected computers but can also be created by using malware to take control of a computer without the owner’s knowledge. Botnets are usually created by exploiting vulnerabilities in web browsers and operating systems, but they can also be created from stolen login credentials or stolen SIM card numbers. A zombie army is a group of compromised computers that are controlled by an attacker with the goal of spreading malware or other harmful programs. A zombie army can be created by infecting computers with malware and then automatically downloading new versions of that malware onto each machine’s hard drive. Botnets and zombie armies have been around for many years, but they have evolved over time as technology improves and criminals become more sophisticated in their methods.
