The Synthetic Exercise World Format provides a neutral and reusable reference environment for cyber threat intelligence exercises, drills, training scenarios, and documentation. By using fictional countries, organizations, sectors, infrastructures, and threat actors, participants can discuss realistic CTI concepts without implicitly referring to real geopolitical situations, real victims, or real adversaries. This helps trainers, analysts, vendors, public institutions, and standardization bodies focus on the structure, quality, and interoperability of the information rather than on politically sensitive interpretations.
Neutrality is especially important when creating reference material for CTI formats, taxonomies, sharing models, or operational procedures. Real-world examples can unintentionally introduce bias, diplomatic sensitivity, legal concerns, or disagreement between participating countries and organizations. A synthetic world avoids these issues by offering realistic but non-attributable entities that can be safely used in examples, schemas, test cases, playbooks, and exercises. This makes the reference document easier to adopt across different jurisdictions and communities.
A shared synthetic environment also improves consistency. Instead of each exercise or standard document inventing its own partial examples, the same fictional countries, companies, sectors, and threat actors can be reused across multiple tools and formats. This makes it easier to compare implementations, validate parsers, test data models, and demonstrate interoperability between CTI platforms. The format can become a common neutral vocabulary for examples, much like test datasets are used in software engineering.
The Synthetic Exercise World Format also supports realistic scenario design without exposing sensitive national, sectoral, or organizational information. Exercise planners can model cross-border incidents, supply-chain compromises, sector-specific threats, vulnerability disclosure workflows, and intelligence-sharing procedures while avoiding references to real critical infrastructure or real governmental relationships. This lowers the barrier for participation and allows organizations with different confidentiality requirements to collaborate in the same scenario.
Including the Synthetic Exercise World Format in reference documentation helps ensure that CTI standards and tools can be widely deployed. It provides a safe, politically neutral, and technically meaningful foundation for examples, demonstrations, conformance testing, and training. By separating the technical purpose of CTI sharing from real-world sensitivities, the format encourages broader adoption, clearer communication, and more inclusive participation across countries, sectors, and communities.

The dataset is a single JSON object with document-level fields such as name, type, uuid, version, description, and a reusable values[] list. Each item in values[] has a common record shape: value, uuid, description, and meta.
| Entity family | Count | Main metadata fields | How it is used |
|---|---|---|---|
| Country | 10 | entity-type, planet, capital, geography, exercise-use |
Provides fictional geopolitical context for neutral exercises and examples. |
| Company | 30 | entity-type, planet, headquarters, sector, exercise-use |
Provides fictional organizations, victims, suppliers, operators, or reporting entities. |
| Threat actor | 20 | entity-type, planet, origin, primary-motivation, sophistication, exercise-use |
Provides non-real actors for neutral attribution and CTI training scenarios. |
company.meta.headquarters == country.value
threat-actor.meta.origin == country.value
all meta.planet values == "Nacre"
This means a tool can group companies and threat actors by fictional country without relying on real-world geopolitical references.

The JSON format follows the standard MISP galaxy structure, making it directly compatible with tools and platforms that already support MISP galaxy definitions. This allows the Synthetic Exercise World data to be loaded, shared, and reused without requiring a custom parser or dedicated data model. As a result, countries, companies, and threat actors from the synthetic dataset can be integrated into existing MISP-compatible workflows for exercises, documentation, testing, and training.
This field guide accompanies the revised fictional atlas map. The map is designed for neutral cyber-exercise planning and keeps the original synthetic country, company, and threat-actor relationships while making the visual layout easier to read.
