README

Fibratus

Adversary tradecraft detection, protection, and hunting

Get Started »

Docs • Rules • Filaments • Download • Discussions

Fibratus detects and eradicates advanced attacker tradecraft by scrutinizing and asserting a wide spectrum of system events against a behavior-driven rule engine and YARA memory scanner.

Events can be routed to a wide range of output sinks or written to capture files for local inspection and forensic analysis. With filaments, you can extend Fibratus with your own tooling and tap into the full power of the Python ecosystem.

In a nutshell, the Fibratus mantra is built on three pillars: realtime behavior detection, memory scanning, and forensics.
