IoCs

An IoC in the AEGIS context is a behavioral fingerprint, substrate signature, or technique identifier that AEGIS has published to the network because the cross-tenant aggregator promoted a Managed Rule against it. The IoC feed lives at GET /v1/trust/iocs and is encoded as a STIX 2.1 bundle. The feed is the L5 layer of the Protection Network — the public transparency surface that lets external SIEMs, threat-intel platforms, and partner networks consume the same indicators AEGIS pushes to every gateway internally.

The STIX 2.1 wire format

Every IoC row maps to a STIX 2.1 indicator SDO. Mnemom-specific metadata is carried in a single property-extension per indicator, identified by a stable extension-definition ID:
extension-definition--mnemom-aegis-2026-05
Field names in the extension are stable: mnemom_type, mnemom_value, mnemom_tlp, mnemom_synthetic, mnemom_related_advisory_id. STIX consumers that do not understand the extension MUST ignore it per STIX 2.1 §11. The full wire format — bundle shape, indicator SDO shape, IoC type → STIX pattern mapping, confidence numeric mapping, endpoint behavior — is specified at /specifications/ioc-stix-mapping. This concept page covers the conceptual surface; the spec covers the wire.

The IoC type taxonomy

Mnemom’s IoC types and their STIX 2.1 pattern surface:
Mnemom IoC typeSTIX patternWhat it represents
sha256[file:hashes.'SHA-256' = '<value>']File / artifact hash
domain[domain-name:value = '<value>']DNS name
url[url:value = '<value>']URL
substrate_fingerprint(no STIX pattern emitted)An AI substrate identity flagged for behavioral deviation. See Substrate fingerprint.
technique_id(no STIX pattern emitted)A MITRE ATT&CK or MITRE ATLAS technique identifier
For substrate_fingerprint and technique_id indicators, the value is carried in the Mnemom extension’s mnemom_type and mnemom_value fields. STIX 2.1’s standard pattern grammar does not have native predicates for these, so consumers that want to match on them should read the extension fields directly.

Empty-by-design at GA — the calm-at-GA contract

If at GA the network is genuinely calm, the thermometer says calm, the advisory list shows the synthetic seed post-mortem, the IoC feed is empty. That’s not a stub — that’s the system telling the truth.
At GA the bundle is { "type": "bundle", "id": "bundle--<uuid>", "objects": [] }. Customers polling the feed see an empty objects array; the field is reliable. When AEGIS publishes a real IoC, it carries mnemom_synthetic: false in the Mnemom extension. The synthetic flag is the field customers can rely on to distinguish real published indicators from any documentation-only or test-seed entries. See AEGIS — calm-at-GA contract.

Consumption

The feed is consumable by any STIX 2.1-aware tool (MISP, OpenCTI, Anomali, ThreatConnect, custom pipelines). Customer integration is documented end-to-end in the IoC feed consumption guide, including:
  • Authentication (X-Mnemom-Api-Key)
  • Query filters (?type=, ?after=, ?limit=)
  • Pagination via the next_after bundle-level extension
  • Refresh cadence (recommended 5-15 minutes via cron; rate limit 1 req/sec/IP, KV-backed)
  • Mapping Mnemom IoC types into downstream tooling
The wire format reference is /specifications/ioc-stix-mapping; the runnable how-to is the guide.
