Master these 15 tools and you can hack 90% of everything

🎯 The Truth About Tools

Beginners think: "I need 100+ tools to be a hacker"

Reality: "Master 15 tools and you'll out-hack 90% of people"

This chapter shows you the ONLY tools that matter.

🔥 Tier 1: Must-Master Tools (Use Daily)

1. Nmap - Network Scanner 🗺️

What it does: Finds computers and services on networks

Why it's critical: Every hack starts with reconnaissance

Basic Commands:

# Scan a single target
nmap 192.168.1.1

# Scan multiple targets
nmap 192.168.1.1-254

# Scan for specific ports
nmap -p 80,443,22 target.com

# Aggressive scan (fingerprinting)
nmap -A target.com

# Stealth scan (avoid detection)
nmap -sS target.com

Real Example:

nmap -sV -sC scanme.nmap.org

This command finds services and runs default scripts

Master Level: Can scan networks without being detected

2. Burp Suite - Web App Testing 🕷️

What it does: Intercepts and modifies web traffic

Why it's critical: 80% of bugs are in web applications

Essential Features: - Proxy: Intercept requests/responses - Spider: Map application structure
- Intruder: Automated attacks - Repeater: Modify and replay requests

Basic Workflow: 1. Set browser proxy to 127.0.0.1:8080 2. Browse target application 3. Intercept requests in Proxy tab 4. Send interesting requests to Repeater 5. Modify parameters to find vulnerabilities

Pro Tip: Use Burp extensions like Logger++, Autorize, ParamMiner

Master Level: Can find complex logic flaws using Burp

3. Metasploit - Exploitation Framework 💥

What it does: Exploits known vulnerabilities automatically

# Set payload
set payload linux/x86/shell/reverse_tcp

# Run the exploit
exploit

Common Payloads: - windows/x64/meterpreter/reverse_tcp - Windows reverse shell - linux/x86/shell/reverse_tcp - Linux reverse shell - php/meterpreter/reverse_tcp - Web application shell
