Pentesting

You can build a self-contained pen testing lab on a Raspberry Pi 5 running Kali Linux ARM64. Add a battery HAT, a 7-inch display, and a wireless adapter that does packet injection. Total cost lands between $200 and $250. The result is a pocket-sized hacking kit that runs Nmap, Burp Suite, Wireshark, Aircrack-ng, and Metasploit in the field, at CTF events, or on jobs where you can’t lug a laptop.
