While investigating multiple incidents using Cisco telemetry, analysts notice that attackers consistently use valid credentials,...

The correct answer isit exposes consistent attacker tradecraft. Attribution relies on identifyinghow attackers behave, not just what tools or infrastructure they use.

Using valid credentials, avoiding malware, and abusing remote management protocols representintentional operational choices. These behaviors are difficult to change and often persist across campaigns.

Option A and B focus on artifacts that attackers frequently rotate. Option D assumes exploitation, which may not be present at all.

Cisco-aligned threat hunting emphasizes:

MITRE ATT&CK technique mapping

Behavioral consistency

Operational patterns

This information enables analysts to compare activity against known adversary profiles maintained by Cisco Talos and other intelligence sources.

Thus,Option Cis the correct answer.
