CTI & blue-team reading

This page is the protocol-level proof hub for heralding on smtp. Prefer the full run over quick for operational decisions. Numbers without the verbatim SCORECARD (or report.json) are not trustworthy citations.

Module interpretation (this protocol)

Module Score Analyst reading
A — Protocol Fidelity 100.0 Clean SMTP banner/FSM for spam-relay probes and credential harvesting.
B — Behavioral Realism 82.5 Accepts lab traffic patterns; not a full MTA queue/delivery story.
C — Telemetry Quality 55.0 Enable Heralding file/syslog/hpfeeds in production — lab had logging disabled.
D — Safety & Containment (C) 75.0 Air-gap attestation; δ_C=0.5625 from C below Safety Gate threshold.
E — Scalability & Latency 100.0 SMTP listener stayed up under harness concurrency.
F — Static Code Audit 70.0 Static pass on upstream Heralding sources in this lab layout.
δ_C 0.5625 Safety Gate multiplier applied to composite UHQS.
  • CTI: use Module A/B to judge engagement depth (scanner noise vs post-auth TTPs). Low B usually means credential/connection intelligence, not interactive malware staging.
  • Blue team: verify Safety Gate (Module D / δ_C) before Internet exposure; wire SIEM shipping yourself — Module C is harness visibility, not your pipeline.
  • Replication: commands live in the product tutorial; environment limits in the methodology.
