Question 250
New detections resemble an old actor's technique but use unrelated malware and infrastructure. What is the MOST appropriate analyst action based on the evidence?
Explanation
Correct Answer
Single technique overlap can be coincidental across unrelated intrusions. Assess campaign clustering uncertainty.
Incorrect Answers
Commodity tools alone are insufficient to identify a unique threat actor. It would avoid false APT attribution from dual-use tooling, but it would not assess campaign clustering uncertainty.
Cloud hosting and proxy routing make geolocation weak evidence of attacker nationality. That is relevant to confidence-adjusted actor attribution, not to assess campaign clustering uncertainty.
Attribution corrections must propagate to downstream decisions. It would correct stale internal actor classification, but it would not assess campaign clustering uncertainty.
