🛠️ Tools Used in Hacking

(Nmap, Wireshark, Metasploit, Burp Suite)

⚠️ These tools are used by Ethical Hackers and Security Professionals for security testing. Using them without permission is illegal.

1️⃣ Nmap (Network Mapper)

📌 Definition

Nmap is a powerful open-source network scanning tool used to discover hosts, open ports, services, and vulnerabilities on a network.

🎯 Purpose

  • Identify live systems

  • Detect open ports

  • Discover running services

  • Detect OS and service versions

🔍 Key Features

  • Port Scanning

  • OS Detection

  • Version Detection

  • Network Mapping

  • Vulnerability Scanning (with scripts)

📊 Types of Scans in Nmap

  • TCP Connect Scan

  • SYN Scan (Stealth Scan)

  • UDP Scan

  • Ping Scan

  • OS Detection Scan

🧠 Real-World Use

Security teams use Nmap to check which ports are exposed and whether unnecessary services are running.

2️⃣ Wireshark

📌 Definition

Wireshark is a network protocol analyzer used to capture and inspect network traffic in real-time.

🎯 Purpose

  • Monitor network traffic

  • Analyze suspicious activity

  • Detect network attacks

  • Troubleshoot network issues

🔎 Key Features

  • Live packet capture

  • Deep packet inspection

  • Protocol analysis

  • Filtering traffic

  • Export capture files

📦 What It Can Analyze

  • HTTP

  • HTTPS

  • FTP

  • DNS

  • TCP/IP

  • ARP

🧠 Real-World Use

Used to detect:

  • Packet sniffing

  • Man-in-the-Middle attacks

  • Suspicious traffic

3️⃣ Metasploit

📌 Definition

Metasploit is a penetration testing framework used to find, exploit, and validate vulnerabilities in systems.

🎯 Purpose

  • Exploit known vulnerabilities

  • Test system defenses

  • Perform penetration testing

🔥 Key Components

  • Exploits (code to attack vulnerabilities)

  • Payloads (code executed after exploitation)

  • Auxiliary modules (scanners, sniffers)

  • Post-exploitation tools

📌 Common Payloads

  • Reverse Shell

  • Meterpreter

  • Command Shell

🧠 Real-World Use

Used by security professionals to test if systems are vulnerable to known exploits.

4️⃣ Burp Suite

📌 Definition

Burp Suite is a web application security testing tool used to find vulnerabilities in websites.

🎯 Purpose

  • Test web applications

  • Detect security flaws

  • Intercept web traffic

🔍 Key Features

  • Intercepting Proxy

  • Web Scanner

  • Intruder (brute force testing)

  • Repeater (modify requests)

  • Decoder

🛡️ Vulnerabilities It Detects

  • SQL Injection

  • Cross-Site Scripting (XSS)

  • CSRF

  • Authentication flaws

  • Session management issues

Computers are electronic devices that are designed to process, store, and retrieve data. They are used for a wide variety of purposes, from personal computing to complex scientific simulations and industrial automation. A computer consists of various hardware components, including a central processing unit (CPU), memory, storage devices, input/output (I/O) devices such as keyboards, mice, and displays, and various other peripherals. Computers communicate with each other over networks, which are interconnected groups of computers that share resources and information. The internet is a global network that connects millions of computers around the world and enables communication and information sharing on an unprecedented scale. The field of computer science is concerned with the study of computers and computational systems, including their design, development, and application. It encompasses many subfields, including artificial intelligence, computer graphics, databases, programming lang...

Computer Generation

 There are five generations of computer:  First generation– 1946 - 1958  Second generation– 1959 - 1964  Third generation– 1965 - 1970  Fourth generation– 1971 - today  Fifth generation– Today to future The First Generation   The first computers used vacuum tubes for circuitry and magnetic drums for memory, and were often enormous, taking up entire rooms.  They were very expensive to operate and in addition to using a great deal of electricity, generated a lot of heat, which was often the cause of malfunctions. The Second Generation   Transistors replaced vacuum tubes and ushered in the second generation of computers.  One transistor replaced the equivalent of 40 vacuum tubes.    Allowing computers to become smaller, faster, cheaper, more energy-efficient and more reliable.  Still generated a great deal of heat that can damage the computer. The Third Generation  The development of the integrated circuit was ...
