What is Hacking and Ethical Hacking Legal or Illegal? || LN-TECHINFO

Today we will know what is Hacking and how many types of hackers are there. Nowadays the demand for computers and smartphones has increased so much that people cannot complete their work except these two things. Computers are used everywhere whether we do our own business or work in a company or bank. It is mandatory to use a computer to run a company or to run a business because with the help of this, we do a lot of work and calculations in a few minutes. Just as you have to face small and big problems in completing every task, in the same way, while working in computers, many problems have to be faced.

You must have heard about Cyber-crime, if I have not heard, I will tell you. Cyber-crime is a crime in which hackers steal important data and personal files from other people's computers using computers and blackmail them and demand a lot of money from them. Every year due to cyber-crime, many organizations whose data have been stolen, people have to pay millions of rupees to save their data.

In the computer world, this crime is increasing and in such a situation, everyone needs to save their important files of their company and business from these hackers. But here the question arises that after all how to protect the important files kept in computers from being stolen. If you want to know the answer to this question, then read this article, what is Hacking ? And is it legal or illegal ?

What is Hacking

Hacking means finding a weakness in the computer system and then taking advantage of the same weakness to blackmail the owner of that computer. Hacking is done by a person through a computer which we call hacker and he has a lot of knowledge of computer and computer knowledge, so he is expert in stealing data from other computers. Hearing the name of Hacking, it is known that this is a wrong thing because it is illegal and by doing so a person can be punished. But hacking is not wrong every time because not all hackers are the same, some are good hackers and some are bad hackers. Who are the good and bad hackers and what do they do? Let's find out about it further.

Types of Hacking

We can divide Hacking into different categories, for this we will see what has been hacked. I will give you some examples to explain you

Website Hacking - This type of Hacking means to gain unauthorized control over a web server and its associated software such as databases and other interfaces.

Network Hacking - This type of Hacking means to get all the information over a network and for which there are many tools like Telnet , NS lookup, Ping, Tracert, Netstat, etc. The main purpose of doing this is only to harm the network system and its operation.

Email Hacking - This type of Hacking means that the hacker gets unauthorized access to his email account without the owner's permission. Later, he is going to use it for his illigal works.

Ethical Hacking - This type of Hacking means identifying the weaknesses of a system or network and helping the owner to fix it. This is a safe hacking process in which all work is done under the supervision of the owner.

Password Hacking - This type of Hacking means that in which secret passwords are retrieved from data which is stored in the computer system or transmitted by a computer system.

Computer Hacking - This type of Hacking means that the hacker knows the computer ID and password of a computer system by using hacking methods Air so that they get unauthorized access to a computer system. This puts owners at risk of getting their data stolen.

What are the types of hackers?

Basically hackers are of three types, two of them are bad hacker who harm people by doing bad things and one hacker is good which saves us from both these bad hackers. The good hacker is called the white hat hacker, the bad hacker is called the black hat hacker and the one who comes in between these two means the one who does both good and bad works is called gray hat hacker.

1# Black Hat Hacker

Black hat hacker are those who sneak into your computer without your permission and steal your personal data like corporate data, fund transactions details, ATM card details etc. Many things that we keep in the computer, which these hackers They steal and take advantage of our weakness and ask for ransom from us. Black hat hackers are very bad and they harm the other for their benefit.

2# White Hat hacker

White hat hackers are the people who do the complete opposite of the black hat hacker, that is, these hackers take permission and check the security of the computer, they do it only to know or to help a company. How strong is the security of their system and whether that security can be broken easily or not. We are also called White hat hackers as Ethical hacker.

3# Grey Hat Hacker

Gray hat hacker are those who have no intention of personally messing with the computer data of the others or impair their system and they do not even need money in return. But even then, without permission, we try to hack others' computers using their skills. They do this just to learn how to do hacking, so their motive is not bad, so they are not black hat hacker and they tried to hack the computer without permission, so they are not even white hacker, so such hacker We say gray hat hacker. Apart from this, there are some different types of hackers, about whom the information is provided below.

4# Miscellaneous Hacker

Except for the second class of hackers, they are also distributed for their hacking methods. So let's know more about it.

Red Hat Hackers

They are called red hat hackers which is a mixture of both black hat and white hat hackers. She mainly targets government agencies, top-secret information hubs, and all those things which belong to sensitive information to hack them.

Blue Hat Hackers

Blue Hat Hackers are called those who are often freelancer and do not work for any companies but they have complete knowledge about network security, apps, software. Such hackers are used by companies to know the loopholes of their products, for this they provide beta verison of products to them and after all they help companies a lot in this work. Companies also provide them a lot of money. Many companies organize many such competitions to encourage such blue hat hackers.

Elite Hackers

This is a social status among the hackers community, which is available only to selected hackers who have exceptional skills. Like this, they are the most expert players in their work. All newly discovered exploits are the first of these hackers.

Script Kiddie

A script kiddie is called one who is completely non-expert in his field and uses pre-packaged automated tools that are written by others to penetrate someone's computer systems. They do not know anything about those tools and how they work, and that is why they go to Kiddie.

Neophyte

These are the hackers who are "n00b", or "newbie" or "Green Hat Hacker". These people are often new in the field of hacking, who do not know anything about hacking and its technologies.

Hacktivist

A hacktivist is called a hacker who uses technology to hack social, ideological, religious, or political messages. In this, most people use website defacement and denial-of-service attacks.

Ethical Hacking Basic Terminologies

Here we will know about some basic terminologies related to Ethical Hacking which are used a lot in this hacking field and it is very important for all new hackers to know about it.

Adware - Adware is a software designed to force pre-chosen ads to be displayed on the screen.

For example, sending HTTP, FTP or Telnet to higher rate and calling script so that they create object in higher rate .

Botnet - Botnet, also called zombie army, is called a group of computers which is done in the owner's knowledge. Botnets are used to send spam or to attack denial of service.

Brute force attack - A brute force attack is automated and it is the simplest method to gain access to a system or website. It keeps trying different combinations of usernames and passwords again and again until it finds the right combination.

Buffer Overflow - Buffer Overflow is a type of flaw that occurs when more data is written to a block of memory, or buffer, in which the buffer is instructed to hold more than the allocated space.

Clone Phishing - Clone phishing is a type of modification of existing, legitimate email with a false link to trick the recipient so that they provide all their personal information.

Cracker - A cracker is said to modify the software to access its protected features. These are such features which are copy protected.

Denial of service attack (DoS) - This denial of service (DoS) attack is called when a server or a network resource is made available for some time by a malicious attempt which are unavailable to the first users. . Usually, the services that are connected with the host are temporarily interrupted or suspend.

DDoS - This is distributed denial of service attack.

Exploit Kit - This exploit kit is a software system designed to run on web servers, its main purpose is to identify the software vulnerabilities of client machines and exploit the vulnerabilities for which these malicious code Uploads to the client for execution.

Exploit - Exploit is a piece of software, a chunk of data, or sequence of commands that can exploit a computer or network system if a bug or vulnerability arises.

Firewall - Firewall is a type of filter that is designed to keep unwanted intruders away from your computer system or network so that it provides safe communication between systems and users within which firewall.

Keystroke logging - Keystroke logging is a process to track the keys that would have been pressed, yes in a computer (and any touchscreen points used). It is simply a map of computer / human interface. They are used by gray and black hat hackers to record login IDs and passwords. Keyloggers are often secretly installed in a device using a Trojan in a phishing email.

Logic bomb - This is a virus that is secretly inserted inside the system and it is then triggered to met certain conditions. This is the time bomb of the most common version.

Malware - Malware is an umbrella term used to refer to many types of hostile or intrusive software, including computer viruses, worms, Trojan horses, ransomware , spyware, adware, scareware , and other malicious programs.

Master Program - A master program is a program used by a black hat hacker to remotely activate commands and activate infected zombie drones, along with denial of service attacks or spam attacks. is done.

Phishing - Phishing is a type of e-mail fraud method in which sender sends emails that look exactly like legitimate-looking emails, whose main goal is to gather their personal and financial information from recipients.

Phreaker - Phreakers are often considered to be original computer hackers because they break a telephone network illegally, use it to free long distance phone calls or tap someone's calls.

Rootkit - Rootkit is a type of stealthy type software, which is typically malicious, and has been designed in such a way that these are not detected by common security softwares and they can do their work.

Shrink Wrap code - A Shrink Wrap code attack is an act that is used to exploit the holes of unpatched and poorly configured software.

Worms - A type of Worm is a self-replicating virus that can alter files, but it is present within active memory and keeps duplicating itself.

Cross-site scripting - Cross-site scripting (XSS) is a type of computer security vulnerability that is typically found in web applications. XSS enables attackers so that they inject client-side script into web pages which is then viewed by users.

Zombie Drone - You can also call a zombie drone a hi-jacked computer which can be used anonymously for a soldier or 'drone' for malicious activity. For example, distributing unwanted spam e-mails.

What is Ethical Hacking? Is this legal or Illegal?

You have come to know the three types of Hacking and it must have come to know that it is legal to do Ethical Hacking because this hacker hacks the computer by asking and improves the security of the system. Ethical hacker follows some rules to hack the system which is very important such as permission has to be taken before the owner of the computer, protects the privacy of the computer so that no one else can hack, discover the weakness of the computer The tax gives all the details to its owner by making a report.

By doing all these things, Ethical hacker protects a person or a company from the eyes of a bad hacker and also prevents them from being harmed. Big companies hire Ethical hacker in their company to secure their necessary files and corporate data and also give them good salary.

Advantages and Disadvantages of Ethical Hacking

Advantages

With this you can recover your lost information, especially when you forget your password.

With this we can perform penetration testing so that we can check the strength of a computer or network security.

With this we can take adequate preventative measures to prevent security breaches.

By learning this, we can use to protect our computer from malicious hackers.

Disadvantages

First of all, after learning Ethical Hacking, people start doing your wrong things in the greed of money.

From this we can get unauthorized access to one's system and get to know their private information.

With this we can also do privacy violation.

If used in reverse, then any system operation can also be damaged.

What is the Purpose of Ethical Hacking?

Let's know here what the main purpose of Ethical Hacking is and why nowadays everyone is behind it.

Many people do this to show off their hacking knowledge to others.

Some people do it just for fun.

HACKING

Hacking Definition :

A commonly used hacking definition is the act of compromising digital devices and networks through unauthorized access to an account or computer system. Hacking is not always a malicious act, but it is most commonly associated with illegal activity and data theft by cyber criminals.

Hacking refers to the misuse of devices like computers, smartphones, tablets, and networks to cause damage to or corrupt systems, gather information on users, steal data and documents, or disrupt data-related activity.

A traditional view of hackers is a lone rogue programmer who is highly skilled in coding and modifying computer software and hardware systems. But this narrow view does not cover the true technical nature of hacking. Hackers are increasingly growing in sophistication, using stealthy attack methods designed to go completely unnoticed by cybersecurity software and IT teams. They are also highly skilled in creating attack vectors that trick users into opening malicious attachments or links and freely giving up their sensitive personal data.

As a result, modern-day hacking involves far more than just an angry kid in their bedroom. It is a multibillion-dollar industry with extremely sophisticated and successful techniques.

Types of Hacking/Hackers

Black Hat Hackers

Black hat hackers are the "bad guys" of the hacking scene. They go out of their way to discover vulnerabilities in computer systems and software to exploit them for financial gain or for more malicious purposes, such as to gain reputation, carry out corporate espionage, or as part of a nation-state hacking campaign.

These individuals’ actions can inflict serious damage on both computer users and the organizations they work for. They can steal sensitive personal information, compromise computer and financial systems, and alter or take down the functionality of websites and critical networks.

White Hat Hackers

White hat hackers can be seen as the “good guys” who attempt to prevent the success of black hat hackers through proactive hacking. They use their technical skills to break into systems to assess and test the level of network security, also known as ethical hacking. This helps expose vulnerabilities in systems before black hat hackers can detect and exploit them.

The techniques white hat hackers use are similar to or even identical to those of black hat hackers, but these individuals are hired by organizations to test and discover potential holes in their security defenses.

Grey Hat Hackers

Grey hat hackers sit somewhere between the good and the bad guys. Unlike black hat hackers, they attempt to violate standards and principles but without intending to do harm or gain financially. Their actions are typically carried out for the common good. For example, they may exploit a vulnerability to raise awareness that it exists, but unlike white hat hackers, they do so publicly. This alerts malicious actors to the existence of the vulnerability.

Devices Most Vulnerable To Hacking

Smart Devices

Smart devices, such as smartphones, are lucrative targets for hackers. Android devices, in particular, have a more open-source and inconsistent software development process than Apple devices, which puts them at risk of data theft or corruption. However, hackers are increasingly targeting the millions of devices connected to the Internet of Things (IoT).

Webcams

Webcams built into computers are a common hacking target, mainly because hacking them is a simple process. Hackers typically gain access to a computer using a Remote Access Trojan (RAT) in rootkit malware, which allows them to not only spy on users but also read their messages, see their browsing activity, take screenshots, and hijack their webcam.

Routers

Hacking routers enables an attacker to gain access to data sent and received across them and networks that are accessed on them. Hackers can also hijack a router to carry out wider malicious acts such as distributed denial-of-service (DDoS) attacks, Domain Name System (DNS) spoofing, or cryptomining.

Email is one of the most common targets of cyberattacks. It is used to spread malware and ransomware and as a tactic for phishing attacks, which enable attackers to target victims with malicious attachments or links.

Jailbroken Phones

Jailbreaking a phone means removing restrictions imposed on its operating system to enable the user to install applications or other software not available through its official app store. Aside from being a violation of the end-user��s license agreement with the phone developer, jailbreaking exposes many vulnerabilities. Hackers can target jailbroken phones, which allows them to steal any data on the device but also extend their attack to connected networks and systems.

Prevention from Getting Hacked

There are several key steps and best practices that organizations and users can follow to ensure they limit their chances of getting hacked.

Software Update

Hackers are constantly on the lookout for vulnerabilities or holes in security that have not been seen or patched. Therefore, updating software and operating systems are both crucial to preventing users and organizations from getting hacked. They must enable automatic updates and ensure the latest software version is always installed on all of their devices and programs.

Use Unique Passwords for Different Accounts

Weak passwords or account credentials and poor password practices are the most common cause of data breaches and cyberattacks. It is vital to not only use strong passwords that are difficult for hackers to crack but also to never use the same password for different accounts. Using unique passwords is crucial to limiting hackers’ effectiveness.

HTTPS Encryption

Spoofed websites are another common vehicle for data theft, when hackers create a scam website that looks legitimate but will actually steal the credentials that users enter. It is important to look for the Hypertext Transfer Protocol Secure (HTTPS) prefix at the start of a web address. For example: https://www.fortinet.com.

Avoid Clicking on Ads or Strange Links

Advertisements like pop-up ads are also widely used by hackers. When clicked, they lead the user to inadvertently download malware or spyware onto their device. Links should be treated carefully, and strange links within email messages or on social media, in particular, should never be clicked. These can be used by hackers to install malware on a device or lead users to spoofed websites.

Change the Default Username and Password on Your Router and Smart Devices

Routers and smart devices come with default usernames and passwords. However, as providers ship millions of devices, there is a risk that the credentials are not unique, which heightens the chances of hackers breaking into them. It is best practice to set a unique username and password combination for these types of devices.

Protect Yourself Against Hacking

There are further steps that users and organizations can take to protect themselves against the threat of hacking.

Download from First-party Sources

Only download applications or software from trusted organizations and first-party sources. Downloading content from unknown sources means users do not fully know what they are accessing, and the software can be infected with malware, viruses, or Trojans.

Install Antivirus Software

Having antivirus software installed on devices is crucial to spotting potential malicious files, activity, and bad actors. A trusted antivirus tool protects users and organizations from the latest malware, spyware, and viruses and uses advanced detection engines to block and prevent new and evolving threats.

Use a VPN

Using a virtual private network (VPN) allows users to browse the internet securely. It hides their location and prevents hackers from intercepting their data or browsing activity.

Do Not Login as an Admin by Default

"Admin" is one of the most commonly used usernames by IT departments, and hackers use this information to target organizations. Signing in with this name makes you a hacking target, so do not log in with it by default.

Use a Password Manager

Creating strong, unique passwords is a security best practice, but remembering them is difficult. Password managers are useful tools for helping people use strong, hard-to-crack passwords without having to worry about remembering them.

Use Two-factor Authentication

Two-factor authentication (2FA) removes people's reliance on passwords and provides more certainty that the person accessing an account is who they say they are. When a user logs in to their account, they are then prompted to provide another piece of identity evidence, such as their fingerprint or a code sent to their device.

Brush Up on Anti-phishing Techniques

Users must understand the techniques that hackers deploy to target them. This is especially the case with antiphishing and ransomware, which help users know the telltale signs of a phishing email or a ransomware attack or ransomware settlements.
