bruteshark

This package contains a Network Forensic Analysis Tool (NFAT) that performs deep processing and inspection of network traffic (mainly PCAP files, but it also capable of directly live capturing from a network interface). It includes: password extracting, building a network map, reconstruct TCP sessions, extract hashes of encrypted passwords and even convert them to a Hashcat format in order to perform an offline Brute Force attack.

Only use this tool against systems you own or are explicitly authorized to test — see the disclaimer.
