Kraken : Cross Platform Yara Scanner Written In Go

Kraken is a simple cross-platform Yara scanner that can be built for Windows, Mac, FreeBSD and Linux. It is primarily intended for incident response, research and ad-hoc detections (not for endpoint protection). Following are the core features:

• Scan running executables and memory of running processes with provided Yara rules (leveraging go-yara).
• Scan executables installed for autorun (leveraging go-autoruns).
• Scan the filesystem with the provided Yara rules.
• Report any detection to a remote server provided with a Django-based web interface.
• Run continuously and periodically check for new autoruns and scan any newly-executed processes. Kraken will store events in a local SQLite3 database and will keep copies of autorun and detected executables.

Some features are still under work or almost completed:

• Installer and launcher to automatically start Kraken at startup.
• Download updated Yara rules from the server.
