Looks like there is another addition to the RPi where you can get a distro that has a bunch of baked in wifi attack tools. List below:
- Hostapd Karma
- URLsnarf
- DNSspoof
- Kismet
- Squid (code injection capabilities)
- SSLstrip (code injection capabilities)
- nmap
- mdk3
- ngrep
- Captive Portal
- Nessus
- Ettercap
- Tcpdump
- AutoSSH
- Supplicant
- 3G/4G
Of course you could just apt-get them yourself….
