What we publish

One TAXII discovery URL serves every collection. Subscribe a TIP, or download the STIX bundle — free with the access token you claim above. Two kinds below: detections (rules for what suspicious activity to watch for) and indicators (known-bad addresses to block) — pick whichever your stack needs.

RedEye CVE Detections

9,310 CVEs

Use this if you want to catch attacks exploiting the newest vulnerabilities (CVEs).

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

9,310 carry a generated Sigma detection so far; the rest gain detections automatically as CVE Forge runs.

RedEye Threat Indicators

62,549 threat indicators

Use this if you want to block or flag traffic to/from known-malicious IPs, URLs, domains, and file hashes.

Malicious IPs, URLs, domains, file hashes, and botnet C2 infrastructure, aggregated and de-duplicated across RedEye Security's threat-intelligence sources, as STIX 2.1 indicators. Paginated: this collection serves the latest page; the full set is downloadable page-by-page.

Paginated. The TAXII collection and bundle below serve the latest 5,000; the full 62,549 indicators span 13 pages — grab them from the page index. TLP:CLEAR.

ATT&CK coverage graph

Every detection in the Sigma feed, mapped to MITRE ATT&CK and drawn as a living graph — 3,200+ rules across 170+ techniques and every ATT&CK tactic. Each color is one tactic; bigger dots = more detections; lines between techniques mean the same rules cover both. Drag it, zoom it, click a node to see what you get.

Live IP enrichment API

Look up any IP against the RedEye threat-indicator set in one call and get a single source-neutral verdict. Same free token as the feeds.
GET · token requiredhttps://feeds.redeyesecurity.com/api/enrich?ip=172.105.103.223&token=YOUR_TOKEN

Pass your token as ?token= or an Authorization: Bearer header. The response tells you whether the IP is in our threat-indicator feed, plus labels, a confidence score, and first-seen. The observed_scanning and benign_service fields are reserved for future upstream context and currently return null (unknown).

Example responseGET /api/enrich?ip=172.105.103.223 live feed indicator, verdict reflects current state
{
  "ip": "172.105.103.223",
  "verdict": "malicious",
  "confidence": 85,
  "in_redeye_feed": true,
  "observed_scanning": null,
  "benign_service": null,
  "labels": ["c2", "malicious-activity", "sliver"],
  "first_seen": "2026-07-05T09:00:11Z",
  "sources": 1,
  "tlp": "CLEAR"
}

Rate limits & fair use. 100 queries/hour per token (with a per-source-IP backstop) by default — need more? Tell us your use case and we’ll raise your token’s limit. Responses carry X-RateLimit-Remaining; over the limit you get 429 with Retry-After. Usage is monitored — tokens that abuse the service (excessive pulls or scraping) are deactivated and return 403 until you request a new one.

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

Ready-to-run Microsoft Sentinel

Every detection ships with a Sentinel KQL query you can paste straight into an Analytics rule.

Alongside the portable Sigma rule, each STIX indicator now carries a Sentinel-ready query in the x_sentinel_kql field, transpiled by the Forge to the Microsoft ASIM schema. No hand-conversion. Pull the feed, read the field, drop it into a Sentinel Analytics rule.

Want a Sentinel-flavored feed? Add ?x=sentinel to any feed URL. Each indicator is slimmed to just the portable Sigma pattern plus its x_sentinel_kql, so your pipeline gets exactly the query it needs.

CVE detections · Sentinel KQL · token requiredhttps://feeds.redeyesecurity.com/stix/cve-detections.json?x=sentinel&token=YOUR_TOKEN

Not every logsource maps to Sentinel telemetry yet, so an indicator the ASIM pipeline could not translate simply omits the field. Detections that carry a query are ready to deploy as-is.

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.

Subscribe

  1. Add a TAXII 2.1 server (MISP, OpenCTI, ThreatConnect, Sentinel, taxii2-client) using the Discovery URL above, with the free token you claimed above as the API key / Bearer credential.
  2. Select a collection: RedEye Sigma Detection Library or RedEye CVE Detections.
  3. Poll on your schedule, or download a STIX bundle from the links above by appending ?token=YOUR_TOKEN.

Use it with curl

Every feed endpoint needs your free token (claim it above) — pass it as ?token= or an Authorization: Bearer header. Only this landing page is open.
