Hayabusa vs NetworkMiner

Hayabusa is a free, open-source tool for Windows event log forensics and threat hunting. It processes EVTX logs from one host or thousands into CSV, JSON or JSONL timelines. Analysis features include computer and event ID metrics, logon summaries, keyword pivoting, HTML summary reports and MITRE ATT&CK mapping. It supports the Sigma specification, including v2 correlation rules; the project describes its curated detection rules as numbering over 4,000. The project says its multithreaded Rust implementation can deliver up to a 5x speed improvement and describes Rust as memory-safe. Hayabusa can run live on one system, process collected logs offline or hunt across endpoints through the Velociraptor Hayabusa artifact. Results can be imported into Elastic Stack, Timesketch and Timeline Explorer, while JSON can be analyzed with jq. Special Windows live-response packages bundle the program with encoded rules and configuration files to reduce files written to the system and help avoid antivirus false positives on YAML rule files. It runs on Windows, macOS and Linux, but no Linux ARM MUSL binary is provided because it does not run properly. The software uses AGPLv3; detection rules use DRL 1.1.

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.
