📜 Playbook — DNS Record exploitation
- Direction — frame the requirement for DNS Record: what decision does this support, by when?
- Collection — pull the 1 mapped sources (0 free) and the native workbench; capture provenance and observe OPSEC.
- Processing — normalize, de-duplicate and enrich the collected data.
- Analysis — correlate against local holdings; apply ACH; assign confidence.
- Dissemination — open a case, draft a report, share via STIX/MISP.
- Feedback — set an alert rule / watchlist to monitor for change.
⚡ AI Skills & Automation
Automate unattended via the cron pipeline (collect → ingest → resolve → enrich → score → alert).

🎫 DNS Record
A DNS record is a typed entry in a zone (A, AAAA, MX, TXT, NS, CNAME, SOA, etc.) that maps a name to an address, service, or policy value. In investigations records expose infrastructure relationships, mail and hosting providers, SPF/DKIM/DMARC posture, and historical changes that reveal campaign pivots and misconfiguration.
Format: Zone entry: name TTL class type rdata. Type-specific rdata: A=IPv4, AAAA=IPv6, MX=priority+host, TXT=quoted string, NS/CNAME=FQDN, SOA=serial/refresh/retry/expire/minimum.
📡 How it is collected
- Live DNS queries (dig/resolvers)
- Passive DNS aggregation
- Zone-transfer (AXFR) where allowed
- Authoritative-server enumeration
- Certificate and mail-header cross-reference
- DNSSEC / DoH telemetry
