Yeti aims to bridge the gap between CTI and DFIR practitioners by providing a Forensics Intelligence platform and pipeline for DFIR teams. It was born out of frustration of having to answer the question "where have I seen this artifact before?" or "how do I search for IOCs related to this threat (or all threats?) in my timeline?"

In a nutshell, Yeti allows you to:

• Bulk search observables and get a pretty good guess on the nature of the threat, and how to find it on a system.
• Inversely, focus on a threat and quickly list all TTPs, malware, and related DFIR artifacts.
• Let CTI analysts focus on adding intelligence rather than worrying about machine-readable export formats.
• Incorporate your own data sources, analytics, and logic very easily.

This is done by:

• Storing technical and tactical CTI (observables, TTPs, campagins, etc.) from internal or external systems.
• Being a backend for DFIR-related queries: Yara signatures, Sigma rules, DFIQ.
• Providing a web API to automate queries (think incident management platform) and enrichment (think malware sandbox).
• Export the data in user-defined formats so that they can be ingested by third-party applications (SIEM, DFIR platforms).
