Hayabusa vs SUMURI PALADIN

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.

SUMURI PALADIN is a donation-supported live Linux environment for forensic imaging, triage, and recovery. PALADIN 9 LTS uses Ubuntu 24.04 LTS and is modified to prevent changes to attached media and disable automatic mounting at boot. Its graphical Toolbox handles imaging, logical acquisitions, hashing, and device mounting, with read-only options and logging. Included software includes Autopsy, The Sleuth Kit, and other open-source forensic tools. Supported image formats include E01/Ex01, RAW (.dd), SMART, AFF, VHD, and VMDK. PALADIN LTS can mount and image through NFS or SMB networks and supports BitLocker-encrypted Windows partitions from Vista through Windows 10. It integrates Arsenal Image Mounter Remote Agent for advanced mounting and live or remote analysis. Persistent Mode preserves reports and configurations between prepared sessions, subject to extra free space. PALADIN runs as a Linux live environment on 64-bit and 32-bit PC hardware.
