NetworkMiner vs PacketSnitch

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.

PacketSnitch is a desktop application for investigating network traffic in PCAP and PCAPNG captures. It turns files into searchable, protocol-aware information and can extract hosts, credentials, certificates, files, locations, protocols, anomalies and threat-intelligence hits. Analysis tools include stream reconstruction, protocol decoding, complex filters, visualizations, threat-intelligence scoring, file carving, GeoIP enrichment and capture workspaces. Traffic decryption, flow analysis and CLI tools are also listed. ZIP-packaged plugins can be installed through Settings. The bundled Python backend parses captures locally, and the maker says captures are not uploaded. Optional network activity includes configured LLM calls, threat-intelligence lookups and anonymous metrics; metrics can be disabled in Settings. Optional LLM analysis supports Ollama, OpenRouter and Cohere when configured. New installations get full features in Demo mode for 30 days, then move to Free mode with core analysis and reduced functionality. Prebuilt installers are available for Windows 10/11 and Linux DEB or RPM distributions. macOS has no signed installer, though running from source is described. The maker says analysis outputs may not be accurate or complete and should be independently validated before consequential use.
