NetworkMiner vs Wireshark

NetworkMiner analyzes captured network traffic and can sniff live traffic, extracting artifacts such as files, images, emails, and passwords from PCAP files. It also builds a host inventory from IP address information for passive asset discovery and communication overviews. The free edition supports live sniffing and PCAP and ETL parsing on Windows and Linux, but not PcapNG parsing. Professional accepts PcapNG, Pcap-over-IP, and PacketCache data in addition to PCAP, ETL, and live sniffing, and exports results to CSV, JSON-LD, and XML. Its protocol features include file extraction across listed protocols, while VoIP support includes audio extraction from unencrypted calls. Professional also provides OSINT lookups for hashes, IP addresses, domains, and URLs. NetworkMiner does not decrypt HTTPS or other TLS-encrypted sessions. Extracted data stays on the end-user device rather than in the cloud. The source code is GPLv2 free and open source. Netresec warns that opening PCAPs can automatically extract malware and recommends Linux or Windows Sandbox to reduce self-infection risk.

Wireshark is a free network protocol analyzer for capturing and examining network traffic. It supports live capture and offline analysis through a graphical interface or the TShark terminal utility, and can inspect hundreds of protocols. Display filters narrow what appears during analysis, though their syntax differs from capture filters. Wireshark reads and writes capture formats including pcap and pcapng, and can decompress gzip-compressed files. Analysis features include VoIP tools, packet coloring rules, and exports to XML, PostScript, CSV, or plain text. It can decrypt traffic for protocols including IPsec, Kerberos, SSL/TLS, WEP, and WPA/WPA2. The software is available for Linux, macOS, and Windows under GNU General Public License version 2, with no license fee for the full version. Windows packages include Npcap, which is needed for live packet capture. What a capture can show depends on the operating system, capture library, network interface, and network configuration; switched networks may not expose unicast traffic between other ports.
