what is hacking ?
javatpoint java interview questions and answers
Hacking is the illegal gaining access of a system, network, or data on which the hacker has no rights of access whatsoever. Examples of hacking include getting into a foreign social networking account without consent; bypassing security protocols to enter a restricted company database; intercepting a conversation taking place on a private messaging application; etc.
Several techniques are used by hackers to exploit vulnerabilities, including phishing attacks, brute-forcing passwords, spoofing, and exploiting software loopholes. Knowing the best practices regarding cybersecurity will help you protect your and your organization’s data against threats.
What is Ethical Hacking and Ethical Hacking Tutorial
Anyone legally attempting to penetrate a system in order to find vulnerabilities is called an ethical hacker. In contrast to malicious hackers, ethical hackers work with permission to help prevent and defend against possible threats.
Working by simulating actual cyberattacks, ethical hackers help in fortifying organizations’ security infrastructures. They cause the same tools, techniques, and methodologies that would be used by black-hat hackers to come into play, but with the intent to save networks, applications, and sensitive data. The primary purpose of ethical hacking consists of discovering and correcting security gaps before a malicious attacker can exploit them and thus guarantee a better secure digital environment.
Types of Hacking
Hacking is the actual act of entering into systems, networks, or data, without authorization. Depending on the intent, the target, and the technique used, hacking can be classified into several types. Below are the major types of hacking:
- White Hat Hacking (Ethical Hacking)
✅ Purpose: Security Enhancement
White Hat Hacking or Ethical Hacking is being conducted by security professionals to locate and fix vulnerabilities in systems before black hat hackers exploit them. Ethical hackers have the permission to undertake actions that are legal in their effort to fortify cybersecurity.
Examples include:
Penetration Testing: Putting up simulated real-time cyber attacks to test up security defenses.
Vulnerability Assessment: Scanning and patching security holes in the networks and applications.
Security Audits: Checking compliance with security standards.
- Black Hat Hacking (Malicious Hacking)
❌ Purpose: Criminal Activities
Black Hat Hackers are cybercriminals who break into systems without any authorization. They steal data, disable operations, and spread malware. Whatever they do is illegal and leads to financial and reputational losses.
Examples:
Phishing Attacks- Fraudulently sending e-mails that steal login credentials.
Ransomware Attacks- Encryption of data while demanding a ransom.
Identity Theft- Theft of personal information to commit fraud.
3. Grey Hat Hacking (Ethical and Unethical Mixture)
⚠️ Aim: Testing Systems Not Approved by Owners
Grey Hat Hackers are such hackers who fall between White Hat Hackers and Black Hat Hackers; they would break into systems without permission to inform the organization about a flaw in security. However, even though they do not work for malicious purposes, their methods are still unauthorized.
Examples include:
Finding vulnerabilities in a website without legally authorized discover and reporting them.
Exposure of security loopholes of organizations with no profit hacking intentions.
- Red Hat Hacking (Vigilante Hacking)
Purpose: To counter hackers
Red Hat Hackers, known as vigilantes, are in the service of countering Black Hat hackers. Instead of reporting security threats, they take matters into their own hands and go after malicious hackers by attacking their systems.
Examples:
Attacking the systems of ransomware operators.
Using hacker networks’ own vulnerabilities to destroy these networks.
5. Blue Hat Hacking (Prevention Testing)
🔵 A purpose: Security Checking Prior to Deployment
Organizationally hire Blue Hat Hackers in testing the software, applications or networks for possible vulnerabilities prior to actual consumer launch. Make sure that any kind of risks to security are kept low when the systems are going live.
Examples:
Spot security loopholes in a new version of software before it is open for client access.
Vulnerability testing in networks of companies.
- Green Hat Hacking (beginner hackers)
🟢 Purpose: To learn and experiment!
Green hat hackers are beginners in the hacking world and want to learn about cybersecurity, penetration testing, and programming. They might not have experience but have plenty of curiosity about hacking techniques.
Examples of these are:
Learning ethical hacking by taking an online course.
Carrying out various experiments with hacking tools in a safe, legal environment.
- Script kiddies (amateur hackers)
🟡 Purpose: to hack for fun or recognition.
Generally speaking, the script kiddies are unskilled hackers who pop in pre-written hacking tools or scripts without well-formed technical knowledge. Most of them hack for fun, for publicity, or for small disruptions without any serious market intent.
Examples:
Launching DDoS (distributed denial of service) attacks against websites.
Defacement of websites by hacking methods.
- State-sponsored hacking (Government hacking)
🏛️ Purpose: Cyber Warfare & Intelligence Gathering
Governments hire hackers for the purpose of cyber espionage, the disruption of enemy infrastructure, or strengthening national security. These hackers may work under the direction of government agencies to either protect national interests or conduct attacks against foreign entities.
Examples:
Cyberattacks against the defense systems of rival countries.
Surveillance of foreign government networks.
Interference with terrorist communication lines.
9. Hacktivism (Hacking for Political or Social Causes)
🎭 Purpose: Protest Through Cyber Attacks
Hacktivists use hacking to promote political, social, or environmental causes. They may expose corruption, censor content, or disrupt services to draw attention to their agenda.
Examples:
Defacing government websites to disseminate a message
Leaking secret papers to expose corruption
Disrupting the networks of organizations that oppose them.
