  Introduction Web security testing is an essential part of cybersecurity, and automated tools play a key role in identifying vulnerabilities quickly. Nikto is one of the most effective open-source tools used for scanning web servers and detecting security issues. This guide explains how to use Nikto step by step, making it ideal for beginners in penetration testing and ethical hacking. What is Nikto Nikto is an open-source web server scanner designed to detect vulnerabilities, outdated software, and misconfigurations. It performs comprehensive tests against web servers and identifies potential security risks. Nikto is widely used in penetration testing tools and vulnerability scanning processes. Why Use Nikto Detect outdated server software Identify common vulnerabilities Find misconfigurations in web servers Perform automated web security scanning Installation Install Nikto on Kali Linux: sudo apt install nikto Check version: nikto -Version Basic Nikto Commands 1. Scan a Websit...

  Overview Password security remains one of the most critical aspects of cybersecurity. When weak passwords are used, attackers can exploit them using advanced cracking tools. Hashcat is one of the most powerful tools designed for this purpose. What is Hashcat? Hashcat is an advanced password recovery tool that uses GPU acceleration to crack hashes at high speed. It supports a wide range of hashing algorithms and attack modes. Why Hashcat is Important Hashcat is widely used because: Extremely fast performance using GPU Supports multiple attack methods Works with hundreds of hash types Highly customizable Installation On Kali Linux: sudo apt install hashcat Basic Usage Example command: hashcat -m 0 -a 0 hash.txt wordlist.txt Command Breakdown -m 0 → Hash type (MD5) -a 0 → Dictionary attack hash.txt → Target hash file wordlist.txt → Password list Attack Modes Dictionary Attack Uses a predefined list of passwords. Brute Force Attack Tries all possible combinations. Hybrid Attack Combi...

  Overview Before attempting to crack a hash, you must first identify its type. Different algorithms such as MD5, SHA-1, and bcrypt require different cracking approaches. Hash identification tools help you determine the most likely algorithm quickly and accurately. hashid is a simple and effective utility used to identify hash types based on patterns and characteristics. What is hashid? hashid is a lightweight command-line tool that analyzes a given hash string and suggests possible hashing algorithms. It compares the structure and length of the hash with known signatures. Why Hash Identification Matters Correct identification is essential because: Each algorithm requires a different cracking mode Choosing the wrong type wastes time and resources Accurate detection improves success rate Installation On Kali Linux: sudo apt install hashid Basic Usage Identify a hash: hashid 5f4dcc3b5aa765d61d8327deb882cf99 Sample Output The tool may return multiple possible matches such as: MD5 NTLM...

  Introduction In penetration testing and cybersecurity, the first step is always reconnaissance. Before identifying vulnerabilities, you need to understand the target system—what services are running, which ports are open, and what technologies are in use. One of the most powerful tools for this purpose is Nmap (Network Mapper). What is Nmap? Nmap is an open-source network scanning tool used to discover hosts and services on a network. Security professionals use Nmap to: Identify active devices Detect open ports Discover running services Gather system information Why Nmap is Important Nmap plays a crucial role in the reconnaissance phase: Network Discovery It helps identify which systems are online. Port Scanning You can find open, closed, and filtered ports. Service Detection Nmap can detect the version of services running on ports. Security Assessment It helps identify potential entry points for attackers. Installing Nmap On Kali Linux: sudo apt install nmap Basic Nmap Commands ...

  Introduction During reconnaissance and penetration testing, understanding a target’s defensive setup is critical. Before attempting any testing, security professionals need to know what protections are in place. One of the most common defenses used by modern web applications is a Web Application Firewall (WAF). To identify this protection layer, a specialized tool called WafW00f is widely used. What is WafW00f? WafW00f is an open-source reconnaissance tool designed to detect the presence of a Web Application Firewall. It helps security testers determine: Whether a WAF is protecting the target The specific type or vendor of the WAF This information is useful when planning testing strategies and understanding possible restrictions. What is a Web Application Firewall (WAF)? A Web Application Firewall (WAF) is a security system that monitors and filters incoming HTTP/HTTPS traffic between users and a web application. It protects against attacks such as: SQL Injection Cross-Site Scrip...
