What is Hacking?
Hacking, often known as cyber hacking, is the act of illegally or unusually breaking into computer systems, networks, or digital devices without authorisation. Although criminal hackers use security flaws to steal information or commit cybercrimes, hacking is not necessarily adverse; users who alter their own devices are also regarded as hackers. This has led to the growth of a massive cybercrime economy that rivals the GDP of developed countries, with criminals profiting from cyberattacks, the selling of software, and stolen data.
But ethical hackers are just as important to the cybersecurity landscape; they aim to improve security protocols rather than undermine them. In order to test security systems, find vulnerabilities, and support law enforcement in thwarting cyber threats, ethical hackers are essential. Their sources of income are helping businesses strengthen their defences against cyberattacks or working with law enforcement to take down hostile hacker networks.
Hacking is, at its core, the vicious exploitation as well as the moral improvement of computer network security.
Malicious Hackers vs. Ethical Hackers
Hackers who practice ethics, sometimes known as “white hat” hackers, use their expertise to find and fix security flaws in systems, networks, and software. By actively spotting vulnerabilities before malicious hackers can make use of them, their goal is to strengthen cybersecurity. Working within the law and with consent from the owners of the systems they’re supporting, ethical hackers respect boundaries.
Meanwhile, malicious hackers, or “black hat” hackers, exploit security flaws for their benefit, frequently with bad intentions. For nefarious, political, or commercial gain, they might steal confidential data, interfere with services, or harm systems. They usually act without permission, and their actions are illegal. Furthermore, “grey hat” hackers are those who partake in actions that lie between ethical and malevolent hacking; they occasionally take advantage of vulnerabilities without authorisation but without malicious intent.
Common Hacking Procedures
- Phishing: Sensitive information, such as credit card numbers, passwords, and personal information, is obtained by tricking recipients with deceptive emails or texts.
- Social Engineering: Using deception or impersonation to coerce people or employees into disclosing private information or doing actions that jeopardise security.
- Exploiting Software Vulnerabilities: Hackers with malicious intent abuse flaws in operating systems or software to obtain unauthorised access to networks, run harmful code, or steal information.
- Brute Force Attacks: Using this technique, illegal access to a system or account is made available by methodically attempting every conceivable password combination until the right one is discovered.
- SQL Injection: By submitting fraudulent SQL queries into a web application’s input fields, hackers can manipulate databases, obtain confidential information, or compromise the security of the application.
- Cross-Site Scripting (XSS): Injecting dangerous scripts into other users’ web pages in order to deface websites, take advantage of session cookies, or reroute users to unsafe websites.
- Man-in-the-Middle (MitM) Attacks: Intercepting a conversation in order to modify data, spy on private information, or assume the identity of one of the parties.
- Distributed Denial of Service (DDoS) Attacks: Launching an excessive amount of traffic from many sources to a targeted system or network, making it unavailable to authorised users.
- Keylogging: Keystrokes on a computer or mobile device can be recorded by malicious software or hardware, which can then be used to steal private data like credit card numbers or passwords.
- Remote Code Execution (RCE): Remotely executing arbitrary code by taking advantage of flaws in software or systems, giving attackers complete control over the target system.
