Airbash is a POSIX-compliant, fully automated WPA PSK handshake capture script aimed at penetration testing. It is compatible with Bash and Android Shell (tested on Kali Linux and Cyanogenmod 10.2) and uses aircrack-ng to scan for clients that are currently connected to access points (AP). Those clients are then deauthenticated in order to capture the handshake when attempting to reconnect to the AP. Verification of a captured handshake is done using aircrack-ng. If one or more handshakes are captured, they are entered into an SQLite3 database, along with the time of capture and current GPS data (if properly configured). After capture, the database can be tested for vulnerable router models using crackdefault.sh. It will search for entries that match the implemented modules, which currently include algorithms to compute default keys for Speedport 500-700 series, Thomson/SpeedTouch and UPC 7 digits (UPC1234567) routers.
