Comprehensive and Detailed
Determining if attacks are from the same actor requires unique attribution. Let's analyze:
A . Code stylometry: Analyzes coding style to identify authorship, the best method for linking malware to a specific actor per CAS-005's threat intelligence focus.
B . Common IOCs: Indicates similar attacks but not necessarily the same actor.
C . IOC extractions: Similar to B, lacks specificity for attribution.
D . Malware detonation: Tests behavior, not authorship.
