Moved the JUDGMENT PANDA references to APT31 following the previous commit.
Off note, Crowdstrike quietly removed the JUDGMENT PANDA section from its GTR-2019 report. However if anyone wants to grab the unchanged report, they can get it [here](https://b-ok.asia/book/3697424/2ab30a).
Based on https://github.com/MISP/misp-galaxy/issues/469
There is an old and persistence issue in attribution world and basically no-one really agrees on this. So we decided to start a specific metadata `threat-actor-classification` on the threat-actor to define the various types per cluster entry:
- _operation_:
- _A military operation is the coordinated military actions of a state, or a non-state actor, in response to a developing situation. These actions are designed as a military plan to resolve the situation in the state or actor's favor. Operations may be of a combat or non-combat nature and may be referred to by a code name for the purpose of national security. Military operations are often known for their more generally accepted common usage names than their actual operational objectives._ from Wikipedia
- **In the context of MISP threat-actor name, it's a single specific operation.**
- _campaign_:
- _The term military campaign applies to large scale, long duration, significant military strategy plans incorporating a series of inter-related military operations or battles forming a distinct part of a larger conflict often called a war. The term derives from the plain of Campania, a place of annual wartime operations by the armies of the Roman Republic._ from Wikipedia
- **In the context of MISP threat-actor-name, it's long-term activity which might be composed of one or more operations.**
- threat-actor
- **In the context of MISP threat-actor-name, it's an agreed name by a set of organisations.**
- activity group
- **In the context of MISP threat-actor-name, it's a group defined by its set of common techniques or activities.**
- unknown
- **In the context of MISP threat-actor-name, it's still not clear if it's an operation, campaign, threat-actor or activity group**
The meta field is an array to allow specific cluster of threat-actor to show the current disagreement between different organisations about the type (threat actor, activity group, campaign and operation).
