RedEye CVE Detections

5,017 CVEs

Sigma detections (STIX indicators) for published CVEs, paired with the related CVE vulnerability objects (NVD-backfilled, CISA-KEV and EPSS enriched).

17 carry a generated Sigma detection so far; the rest gain detections automatically as CVE Forge runs.

Why CVE Forge is different

A brand-new CVE becomes a working detection, automatically, within minutes.

Most feeds hand you indicators (IPs, hashes, domains) and leave the detection engineering to you. The public Sigma corpus is excellent but human-written for known techniques, so a freshly disclosed CVE can sit for weeks, or forever, with no rule.

CVE Forge closes that gap. The moment a CVE lands on NVD, our Etairos-powered pipeline reads the vulnerability and uses an LLM to author a Sigma detection for that specific CVE, then transpiles and validates it. Ready-to-deploy content for vulnerabilities no public rule set has reached yet. Curated breadth from the Sigma Library, plus CVE-specific coverage within minutes from the Forge.

NVD (new CVE) → Etairos LLM authors Sigma → transpile to any query language (SPL · KQL · ES|QL · AQL · Lucene · …) → STIX 2.1 Indicator → TAXII / bundle

Examples

A Forge-generated CVE detection and a Sigma Library rule, both live in the feed right now.

Three standards, three jobs

The thing people mix up: Sigma, STIX, and TAXII are not alternatives. They stack.
Sigma

The detection rule. The logic ("if these log fields match, alert"). Vendor-neutral; transpiles to any SIEM. The content.

STIX 2.1

The format. A standard JSON envelope. A Sigma rule rides inside a STIX Indicator; CVEs are STIX Vulnerability objects. The packaging.

TAXII 2.1

The transport. The HTTP API your tools poll to discover and pull STIX. The delivery. The LLM only authors Sigma; STIX/TAXII are deterministic.
