The Receipts

Real numbers from our production feed:

Last 7 days:        858 new indicators
Hourly updates:     8 threat intel sources
STIX version:       2.1 (OASIS standard)
License:            CC0-1.0 (public domain)
Uptime:             180+ days zero downtime

What Makes This Different

Most "free" threat feeds give you stale IP lists. We give you:

1. SSL Certificate Intelligence - Every IP enriched with cert CN, issuer, self-signed detection
2. JARM Fingerprints - Server-side TLS signatures (Cobalt Strike, Sliver, Brute Ratel detection)
3. JA3 Fingerprints - Client-side TLS signatures (AsyncRAT, Quasar, DcRat attribution)
4. MITRE ATT&CK Mapping - Tactics and techniques on every indicator
5. Confidence Scoring - 0-100 scale so you can tune your thresholds

New This Week: Complete TLS Fingerprint Coverage

JARM (Server-Side)

We scan suspicious IPs and fingerprint their TLS implementation. Cobalt Strike, Metasploit, Sliver, and Brute Ratel each have distinct "accents" in how they do TLS handshakes.

• Cobalt Strike default certs (serial 146473198)
• Self-signed C2 certificates
• DGA-generated certificate CNs
• APT infrastructure patterns (HAINAN, CHINANET)

JA3 (Client-Side) - NEW

Microsoft pulls this feed daily. AT&T pulls this feed daily. Starlink pulls this feed daily. Get the DugganUSA STIX feed — $9/mo →

We now ingest 97 known malware JA3 fingerprints from SSLBL. When malware phones home, its TLS Client Hello has a unique signature.

• AsyncRAT, Quasar, DcRat, BitRAT
• Cobalt Strike beacons
• Mythic, Havoc, Sliver agents

---

What We Don't Do

• We don't paywall the feed
• We don't require registration
• We don't track who downloads
• We don't sell your usage data
• We don't throttle requests

Why? Because security is cumulative. When you block a C2 we discovered, that attacker loses infrastructure. That helps everyone.

Quality Assurance

Every indicator passes through our Judge Dredd 6D Framework:

1. D1 - Commit Compliance: Git-tracked, auditable changes
2. D2 - Corpus Alignment: Cross-referenced against multiple sources
3. D3 - Production Evidence: VirusTotal correlation, honeypot captures
4. D4 - Temporal Decay: Fresh indicators prioritized, stale ones aged out
5. D5 - Financial Efficiency: We don't pay per indicator (no perverse incentives)
6. D6 - Democratic Sharing: Published openly, CC0 licensed
