WiFi Packet Sniffer

Technologies: Java, pcap4J, Wireshark

Done for a Advanced Networks coursework, me and my partner explored whether it was possible to decrypt arbitrary WPA2 packets on a network where the shared key was known. It was discovered to be possible through the use of a wireless adapter in promiscuious mode and a relatively small application. This was paired with a frontend which stored the packet information in a time series database which could then be visualised in Grafana.

Our findings are presented in two reports, which can be found in the source repository.
