Hacking requires a deep understanding of many areas of technology. Being a computer hacker is basically knowing enough about the technology to be able manipulate it in ways it shouldn’t. You don’t have to be an expert in every aspect of computer technology for software development and sharing information. To be a script kiddie or a computer hacker, you must first understand the basics. These are the essential skills you must have to become a hacker.
Networking: It is important to understand the concept behind a computer network. Your targets will be using their private network for any work you do related to the company. You need to understand the basics of a computer network. This includes firewalls, Proxy Servers/Demilitarized Zones, Proxy Servers/NAT, Intrusion Detection Systems and Intrusion Prevention Systems. Also, you should know how data is transferred between different devices.
Command line: As a hacker, you’ll be using the command line a lot. It is important to learn how it works. You can access the command line via the terminal. This is the window that looks black or gray depending on which operating system you have. As an aspiring hacker, you should be able to change directories and run software from the command line. Overthewire challenges are a great way to learn.
Computer Ports: The routine of scanning computer ports when hacking into a machine is to scan it. You can scan ports to find out which services are running on the machine, and what version. This can help you hack into the machine. It is important to know what ports your computer uses, which ports are most vulnerable and what services they use. You can also learn how to scan ports with common tools such as nmap.
Learn how to read code: As a hacker, you’ll be writing, editing and reading computer scripts. You must be able to read and understand computer code. C/C++ Java, C/C++ Java, and PHP are the most commonly used languages in hacking. While you don’t have to be fluent in all the syntaxes of these languages, it is important that you are familiar with basic programming concepts such as functions, variables and loops.
Learn about Kali Linux and its Security Tools: You want to learn how to use some of the most popular hacking software on the market. Although it is nice to be able create your own scripts and tools, a lot of professional penetration testers will use industry-standard tools. Kali Linux will be required to know Metasploit and Burpsuite as well as Wireshark, Wireshark, Wireshark, Nmap and John the Ripper.
Learn the phases of a Penetration Test: If you plan to become a professional hacker, you need to understand the phases involved in a penetration test. This helps you stay focused and ensures that your approach is consistent and structured.
There are many types of payloads: A payload is a script that a hacker uses in order to hack a system. If you receive a fake email, it may try to convince you to download an Excel file containing a virus. The payload is the piece of software they want you to download. This will allow them to execute commands on your computer. The most common payload is the standard computer virus. However, there are many types of payloads. These include trojans, backdoors and rootkits. These different types of malware are classified according to how they spread into trojans, viruses and worms.
What are some common attacks?
Cross Site Skating (XSS):This attack uses client-side code injection. A hacker injects code into a website using forms that allow users input data such as username and password forms. It is possible to insert code into forms that don’t have a way to clean the data entered. This code will be added to infected pages and executed whenever the page loads. Javascript is the most commonly used programming language for XSS. It is important to understand what the attack is and how it works. Being asked to explain it is a common interview question for information security.
SQL Injection: This attack uses the SQL database language. Hackers attempt to bypass security controls by entering SQL statements via forms on the website. This can include usernames, passwords, credit card information, and any other type PII.
Phishing Attacks: Phishing attacks are a form of social engineering attack in which a hacker pretends that they are a trusted entity to get the victim to do a specific action. You can do this by opening an email, sending instant messages, downloading a file, or giving away login credentials. Phishing attacks do not exploit a technical flaw in a system. Instead, they focus on the human element. About half of all data breaches are caused by phishing attacks.
Buffer overflow: This is one of the most difficult types to attack, but can lead to serious exploits. It’s much easier if you have programming experience. Buffer overflow is when data becomes too large to store in the memory buffer. This can cause overwriting of adjacent memory locations. An attacker can control the overwriting memory locations and bypass the usual security measures of the application to execute code on the machine.
DOS/DDOS: When someone attempts to make a machine, or network resource unavailable for its intended users by interrupting the service of the host, it is called denial-of-service/distributed denying of service. This is usually done by sending too much traffic to the resource, so that it can’t respond properly to legitimate requests. This isn’t the only way to do it. You can target a website or web application of a company, or if you are playing video games, a person’s router.
Final Thoughts
This isn’t an exhaustive list of all hacker knowledge, but it does provide a basic overview. If you want to learn how to hack computers, it is important to have a solid understanding of these topics. Technology changes constantly so you must be able to learn new things. While some people want to master a particular career, it may not be for everyone. It’s best for people who are passionate about learning more about the discipline.
