Wiring Live Threat Intel into Sigma Detection with Dynamic Pipelines

RSigma v0.10.0 introduces dynamic pipelines that fetch live threat intelligence at runtime and inject it into Sigma detection rules without modifying the rule files. The approach solves the stale IOC problem by wiring two public sources into a pipeline: Feodo Tracker (a JSON feed of botnet C2 IPs refreshed every 5 minutes) and ioc-finder (a Python tool that extracts IOCs from CISA advisory text). Pipeline YAML declares sources, extraction expressions (jq, JSONPath, or CEL), refresh policies, and error handling. At runtime, the RSigma daemon resolves sources, expands %placeholder% tokens in Sigma rules, and re-fetches feeds on schedule. The result is detection logic that adapts to the threat landscape automatically — no YAML edits, no restarts, no manual IOC management.
