The correct answer iscorrelating attacker behavior across multiple MITRE ATT&CK techniques. This approach focuses onbehavioral detection, which is the cornerstone of effective threat hunting and advanced security operations.
Attackers who abuse legitimate administrative tools—often referred to asliving-off-the-land techniques—intentionally avoid malware-based detections. File hashes, signatures, and known indicators provide minimal value because there may beno malicious files at all. Options A and D sit at the lowest levels of thePyramid of Pain, making them easy for adversaries to evade.
By correlating behavior across multiple ATT&CK techniques—such as credential access, lateral movement, privilege escalation, and command execution—defenders detecthowthe attacker operates rather thanwhat toolsthey use. This forces adversaries to fundamentally change tradecraft, which is costly, risky, and time-consuming.
Option C improves visibility but does not inherently raise attacker cost. Threat intelligence feeds are reactive and often lag behind active campaigns.
From a professional threat hunting perspective, correlating multiple low-signal behaviors into ahigh-confidence attack patternis how mature SOCs detect stealthy intrusions. This method also supports scalable detection engineering, improved alert fidelity, and reduced false positives.
This strategy directly aligns with higher tiers of theThreat Hunting Maturity Modeland the top of thePyramid of Pain, making optionBthe correct answer.
