RITA
Open source framework that analyzes Zeek logs for C2 beaconing, DNS tunneling, and scanning.
Technical Architecture & Overview
RITA, Real Intelligence Threat Analytics from Active Countermeasures, ingests Zeek logs and applies statistical tests to find beaconing patterns, long connections, DNS tunneling, and scanning behavior. It outputs ranked host lists that analysts review, and it pairs with AC-Hunter, the commercial platform from the same company. Deployments typically run on a dedicated analysis box fed by Zeek sensors.
Targeted Technical Use Cases
Finding command-and-control beaconing in Zeek telemetry without a commercial NDR platform.
Evaluation & Trade-offs
Core Strengths
- +Statistical beacon detection catches C2 that signatures miss.
- +Free complement to a Zeek deployment.
- +Simple interpretation of ranked results.
Trade-Offs & Limitations
- -Batch analysis, not real-time detection.
- -Depends entirely on Zeek log quality and retention.
Defensive Security Application
Detecting compromised hosts by their network timing and traffic patterns.
