Query Group Techniques

from mitreattack.stix20 import MitreAttackData

attack = MitreAttackData("enterprise-attack.json")
groups = attack.get_groups()
for g in groups:
    techs = attack.get_techniques_used_by_group(g)

Get Technique Details

technique = attack.get_object_by_attack_id("T1566.001", "attack-pattern")
print(technique.name)          # Spearphishing Attachment
print(technique.x_mitre_platforms)  # ['Windows', 'macOS', 'Linux']
