AttackPattern Object

Attack Patterns are a type of TTP that describe ways that adversaries attempt to compromise targets.

Property Type Description Required?
description Markdown String A description that provides more details and context about the Attack Pattern, potentially including its purpose and its key characteristics. ✓
id String Globally unique URI identifying this object. ✓
name ShortString String A name used to identify the Attack Pattern. ✓
schema_version String CTIM schema version for this entity ✓
type AttackPatternTypeIdentifier String ✓
abstraction_level AttackPatternAbstractions String The CAPEC abstraction level for patterns describing techniques to attack a system.
external_ids String List
external_references ExternalReference Object List A list of external references which refer to non-STIX information. This property MAY be used to provide one or more Attack Pattern identifiers, such as a CAPEC ID. When specifying a CAPEC ID, the source_name property of the external reference MUST be set to capec and the external_id property MUST be formatted as CAPEC-[id].
kill_chain_phases KillChainPhase Object List The list of Kill Chain Phases for which this Attack Pattern is used.
language ShortString String The human language this object is specified in.
revision Integer A monotonically increasing revision, incremented each time the object is changed.
source MedString String
source_uri String
timestamp Inst (Date) The time this object was created at, or last modified.
tlp TLP String Specification for how, and to whom, this object can be shared.
