After several companies in the financial industry were affected by a similar incident, they shared information about threat intelligence and the malware used for exploitation. Which of the following…

Applying code stylometry is a highly specialized and often inconclusive method for attributing authorship, especially for threat actors who actively obfuscate their code.

Looking for common TTPs allows organizations to identify consistent operational methodologies and patterns of attack used by threat actors, providing strong indicators of a shared actor or group.

Using IoC extractions (Indicators of Compromise) helps detect ongoing activity but does not reliably link actors if IoCs like IP addresses or domains are frequently changed or reused by different groups.

Leveraging malware detonation in a sandbox helps understand malware behavior but doesn't inherently reveal the actor's identity or directly link separate attacks to the same actor without further correlation.

Performing malware decompilation is a deep reverse engineering technique to understand malware functionality, which is too granular and resource-intensive as a primary method for linking actors across multiple incidents.

Verifying malware hashes directly identifies if identical malware samples were deployed across different incidents, offering a definitive link regarding the tools used by the presumed same actor.
