In contrast, malicious hacking involves employing techniques to obtain unauthorized entry into computer systems or networks for personal gain or with malicious intent. This form of hacking is considered illegal and can lead to severe repercussions for the hacker if apprehended.

Ethical hacking is becoming increasingly popular as companies and organizations seek to protect their computer systems and networks from cyber-attacks. It is recommended to take the best ethical hacking course with the skills and knowledge to become an ethical hacker. This will help businesses and organizations protect themselves from malicious hacking.

History of Hacking/Hackers

The history of hacking can be traced back to the 1960s when the first generation of hackers emerged at MIT. These early hackers were computer enthusiasts who explored the potential of computer systems and shared their knowledge with others. Over time, the term “hacker” gradually acquired a darker undertone as specific individuals started employing their abilities for malevolent objectives, including data theft, inflicting harm on computer systems, and engaging in cybercrimes.

Kevin Mitnick, who rose to fame in the 1980s and 1990s for his ability to infiltrate computer networks and steal sensitive data, was the first well-known hacker. Mitnick was eventually caught and served time in prison, but his exploits inspired a new generation of hackers.

How Does Hacking Work?

Hackers employ various methods to gain unauthorized access to a system or device. Some of the most common hacking techniques include the following: 

1. Hacking passwords: Hackers often use password-cracking tools, dictionary attacks, or brute force attacks to guess or crack passwords, enabling them to access a user’s account. Additionally, they may use weak password policies, common password patterns, or password reuse to gain unauthorized access. To protect yourself against password hacking, stick to these measures:

• Use strong, unique passwords for each account. 
• A strong password typically incorporates a combination of numbers, special characters, and a mix of uppercase and lowercase letters. 
• Also, implementing two-factor authentication (2FA) can add an extra layer of security by requiring a secondary verification method, such as a code sent to your phone and the password.

2. Infecting devices with malware: Malware, short for malicious software, is designed to infiltrate or damage a computer system. Hackers use malware to compromise a device and access its data or resources. After successfully infiltrating a device, malware can execute a range of activities, including the theft of sensitive information, surveillance of user actions, or granting remote control to the attacker.

• Use trusted antivirus and anti-malware software to safeguard against malware threats. 
• Regularly update your software and operating system to ensure you have the latest security patches. 
• Exercise caution when opening email attachments or downloading files from unfamiliar sources. 
• Additionally, be mindful of the websites you visit and avoid clicking on suspicious links.

3. Exploiting insecure wireless networks: Hackers can exploit weak security measures in wireless networks to intercept data transmissions or gain access to connected devices.

• To protect yourself, avoid connecting to unsecure or suspicious Wi-Fi networks. 
• Consider using a Virtual Private Network (VPN) when connecting to public Wi-Fi networks. 
• A VPN encrypts your data, rendering it more difficult for hackers to intercept. 
• Ensure you safeguard your home wireless network by implementing a robust password and employing encryption protocols like WPA2 or WPA3.

4. Gaining backdoor access: Backdoors are secret access points within a computer system or network which hackers can exploit to gain unauthorized access. Hackers may discover and exploit existing backdoors in software or systems, or they may create their own. To safeguard against unauthorized backdoor access, it is crucial to do the following: 

• Maintain up-to-date software, firmware, and operating systems by applying the latest security patches. 
• Review system logs regularly and monitors for suspicious activities or unauthorized access attempts.

5. Spying on emails: Hackers may intercept and read emails by exploiting vulnerabilities in email protocols or using malware to infiltrate a user’s device. To protect your email accounts, follow these steps: 

• Enable strong passwords and two-factor authentication.
• Be cautious when opening email attachments or clicking links, especially if the email is unexpected or from an unknown sender.
• Regularly monitor your email account for any suspicious activities or unauthorized access.

6. Logging keystrokes: Keyloggers record a user’s keystrokes, allowing hackers to capture sensitive information such as passwords and credit card numbers. To protect against keyloggers, follow these steps: 

• Use updated antivirus and anti-malware software.
• Be cautious when using public computers or shared devices, as they may be compromised.
• Consider using virtual keyboards or password managers, as they can help prevent keyloggers from capturing sensitive information.

7. Creating zombie computers: Infected devices, commonly known as ‘zombie computers,’ can be manipulated remotely by hackers, granting them control and enabling the execution of various cybercrimes, including launching Distributed Denial of Service (DDoS) attacks. To protect against becoming a part of a botnet, stick to the below given measures: 

• Regularly update your devices and software, including antivirus and anti-malware programs. 
• Use firewalls and network security measures to block unauthorized access to your devices. 
• Be cautious when downloading software or files from unknown sources to avoid inadvertently installing malware.

8. Social Engineering: This technique involves manipulating or deceiving users into divulging sensitive information or granting unauthorized access to systems. Hackers may impersonate trusted individuals, use persuasive tactics, or create a sense of urgency to deceive their targets. Protecting against social engineering attacks requires awareness and vigilance. 

• Exercise caution when faced with unsolicited personal or financial information requests, even if they seem to originate from a trustworthy entity. 
• Verify the identity of individuals or organizations before sharing sensitive information or granting access to your systems. 
• Educate yourself and your employees about common social engineering tactics to recognize and respond appropriately to potential frauds.

What Are Some Limitations of Ethical Hacking?

Ethical hacking, also known as penetration testing, involves the deliberate attempt by security professionals to hack into a system or network to identify and resolve vulnerabilities. While ethical hacking can help organizations strengthen their security posture, it has some limitations:

• Time constraints: Penetration testing is often performed within a limited time, which may not be enough to uncover all vulnerabilities.
• Limited scope: Ethical hackers may only be granted access to specific systems or components, leaving other areas untested and potentially vulnerable.
• Human error: As human perform ethical hacking, there is always the possibility of overlooking vulnerabilities or making mistakes.
