1. Introduction to Wireless Networks
Wireless hacking involves exploiting vulnerabilities in wireless networks. The common types are:
WEP (Wired Equivalent Privacy)
WPA (Wi-Fi Protected Access)
WPA2
���️ Hands-On Exercise: Use your Linux setup to run a simple iwconfig command to view available wireless interfaces.
bashCopy code
# To display wireless information
Iwconfig
2. Man-in-the-Middle Attacks
Man-in-the-Middle (MitM) attacks intercept data between two parties.
���️ Hands-On Exercise: Use Wireshark to capture data packets on your own network, but do not attempt this on a network you do not own.
bashCopy code
# Start capturing packets
sudo wireshark
How it ties back to Linux: Wireshark can be installed and run directly from the Linux terminal.
3. SQL Injection Basics
SQL Injection is an attack that targets the data layer of applications.
���️ Hands-On Exercise: On a dummy website, practice inputting SQL queries into a search bar to understand how SQL injection might occur.
sqlCopy code
' OR '1'='1
Clarification: The above SQL query demonstrates how a poorly secured database might be tricked into displaying all records.
4. Data Encryption and Protection
Encryption safeguards data from unauthorized access.
Symmetric Encryption: Same key for encryption and decryption.
Asymmetric Encryption: Different keys for encryption and decryption.
5. Password Cracking Techniques
Brute Force: Trying all possible combinations.
Dictionary Attack: Using a pre-defined list of words.
���️ Hands-On Exercise: Use a tool like John the Ripper to attempt cracking a sample password hash. Remember to do this only on your personal lab setup.
bashCopy code
# Basic John the Ripper syntax
john --format=descrypt password.txt
6. Legal Guidelines
��� As always, hacking activities should only be performed with explicit written consent. Operating without permission is illegal and unethical.
7. Calls to Action & Practical Exercises
Expand Your Toolset: If you haven't already, download Wireshark and John the Ripper.
