• H for Hide IP: Every device has an internet address, much like our home. The term "IP address" refers to this. IP addresses are able to track user location and ISP provider data.

• A for Aim Victim: This definition is widely used. In this context, the term "victim" refers to the owner of the target device.

• C for Crack Encrypt: Hacking language includes the phrases Crack Encrypt. Password cracking is referred to as "cracking" in general. The password here is not unique. Since a password is required for every other account and machine.

• K for Kill Firewall: In general, a firewall is a network security device that monitors and regulates inbound and outbound network traffic. Kill Firewall now refers to disabling the firewall.

• E for Enter into the system: After taking down a firewall, entering the system comes next. The term "system" might now refer to a server, computer, or database.

• R for Return Anonymous: The next stage is to revert to anonymity after breaking into the system and doing your desired actions. To put it simply, return without leaving a trace.

Although the term "hacker" is most commonly associated with security hackers—individuals who use their technical expertise of bugs or exploits to break into computer systems and access data that would otherwise be inaccessible to them—hacking can also be used by law-abiding people in legal situations. For instance, police enforcement organisations occasionally utilise hacking methods to compile evidence against criminals and other malicious people. This involves the use of anonymity technologies (like a VPN or the dark web) to conceal their identities online and acquire the identities of criminals. Similarly to this, clandestine international organisations may employ hacking methods in the course of their lawful operations. On the other side, hacking and cyberattacks are used by state agents, law enforcement, and security organisations (when engaging in warrantless operations).

Definition of Hacker

Originally, the term "hacker" simply referred to an enthusiast of advanced computer technology (both hardware and software) and a follower of the programming subculture. Someone is capable of subverting computer security. If this is done for malicious purposes, the person may also be called a cracker.

Types Of Hackers

• White Hat hackers

White Hat hackers make use of moral hacking methods to guarantee the safety of networks and computer systems. They employ a range of techniques to identify and address security flaws. To evaluate the security of a system, they could make use of intrusion detection systems, port scanners, and other security technologies. They are also proficient in computer programming, network protocols, and cryptography. White Hat hackers may also offer security consulting services, such as assisting businesses in creating secure networks and systems or suggesting how to make already protected systems more secure. They could also be used to check the new systems' security.

• Black Hat hackers

Hackers with malicious intents are referred to as black hats or crackers. They frequently steal, abuse, and sell data, and are typically acting for their financial advantage. Typically, their job is unlawful. In contrast to black-hat hackers, crackers are extremely adept and want to make money rather than just cause damage. Crackers discover exploits for system flaws and frequently take advantage of them by either offering the system owner the solution or passing the vulnerability along to other black-hat hackers who then use it to steal data or collect royalties.

• Grey Hat Hacker

Between White Hat and Black Hat hackers, Grey Hat hackers frequently serve as an intermediary. Without the owner's knowledge or consent, they could look for vulnerabilities in a system and notify the owner when they find any.

What Are The Common Hacking Techniques?

The following widespread hacking methods remain persistent, even though the technological grounds of these techniques are continually changing to stay up with cybersecurity developments:

• Phishing: The malicious hacker generates a fake email that looks to be from a reputable company and requests that the victim opens it. Then, users are tricked into providing their login information and other sensitive data, including their date of birth, social security number, or credit card information.

• Viruses and malicious code: To steal cookies that track online behaviour, hackers introduce harmful malware into website files, such as worms and Trojan horses.

• Operating system attack: The attacker executes the attack and gains access to the operating system depending on the version of the OS.

• Application level Attack: Application-level attacks include SQL injection attacks on web applications

• Shrink wrap code Attack: This type of attack occurs when a hacker notifies a company of a vulnerability but the company fails to apply a fix, allowing other hackers to take advantage of the flaw.

• User interface (UI) redress: This method, sometimes known as "clickjacking," involves creating a fake user interface (UI) and a link on a legitimate website, then tricking the user into clicking the link. The malicious attacker will then have unsupervised access to the user's PC.

• DoS and DDoS: Users are unable to access their computer systems, services, networks, or other information technology (IT) resources via these methods. This method is frequently used by malicious hackers to crash web servers, systems, or networks by interfering with regular traffic.

• Domain Name System (DNS): By rerouting traffic to fictitious sites, the Domain Name System (DNS) cache poisoning or DNS spoofing method takes advantage of DNS clients and web servers.

• SQL injection (Structured Query Language): By inserting SQL code into a web form input field, this approach can access restricted resources and data.

• Keylogger injection: A keylogging application is introduced as malware onto the user's system to track and log their keystrokes. The threat actor can take personal information, login information, and critical company data using this technique.

• Brute force attack: typically, automated tools are used in these assaults to try out different login and password combinations until they locate the one that works.

Motive

Possible explanations for why hackers attempt to access computers and networks have been put forth. First, when systems are breached with the intent to steal credit card information or manipulate banking systems, illicit financial gain is attempted. Second, many hackers take great pride in improving their image within the hacker community by posting their handles on websites they have vandalised or by leaving other signs that they were involved in a certain breach. Third, businesses might learn knowledge about goods or services that can be stolen or utilised as bargaining chips in the market by engaging in industrial espionage. Finally, state-sponsored assaults give nation-states the ability to undertake cyberspace-based warfare and intelligence collection.

Famous Hackers

• Anonymous: A group of people known as Anonymous employs technology to carry out illegal activities. They breach websites, post people's sensitive information online, and generally cause a nuisance.

• Jonathan James: The oldest of three kids, Jonathan James was born in 1983 in Miami, Florida. When he was young, his parents were divorced, and his father left the house. In order to help the family, his mother worked as a nurse, so James moved in with his grandma. James was a bright kid who had a special interest in technology. He started learning computer programming when he was 11 years old, and he quickly started dabbling in hacking. He was able to log into several computers and websites, including those used by NASA and the US military. Software code and other confidential information were taken by him. James was detained and accused of cybercrime in 1999. He was found guilty after an adult trial and given a six-month jail term and a three-year probationary period. After his release in 2000, he carried on his career in the IT sector. When James improperly accessed BellSouth computers in 2007, he was accused of breaking his probation. He was found guilty and might have received a five-year jail term. James committed suicide on May 18, 2008, citing his impending trial as a factor in his fear of the possible outcomes.

• Adrian Lamo: Adrian Lamo became well-known for his hacking endeavours, which he referred to as "penetration testing." He claimed that by disclosing the networks' flaws, he was enhancing their security. He gained access to several groups, but not all of them agreed with him. Lamo's attorneys said that his acts were selfless and that he had not significantly harmed or disrupted the situation. Despite being found guilty, Lamo received high accolades for his ethical hacking abilities and was even hired by several businesses to check network security. Since then, he has published many books on the issue and frequently speaks in front of groups to promote stronger security procedures.

• Kevin Mitnick was found guilty of offences involving computers, including wire fraud, unlawfully intercepting private communications, and computer fraud, as well as fraud and illegal possession of telecommunications equipment. He became known as a notorious hacker as a result of his conduct and was included on the FBI's Most Wanted List. He entered a guilty plea to five charges of wire fraud, two counts of computer fraud, and one count of unlawful wire communication interception in 1999. He received a 46-month jail term in 2000 and was freed in 2003.
