Ambiguous Techniques v1.0

May 13, 2025

Project Summary

Building upon the research of Summiting the Pyramid, Ambiguous Techniques is a methodology to determine malicious intent behind seemingly benign behavior by applying contextual analysis to ATT&CK techniques. Reduce false positives and uncover adversarial use of living-off-the-land activity.

Problem

Many ATT&CK techniques, especially those used in living-off-the-land activity, produce observables that are indistinguishable from benign behavior, making it difficult for defenders to determine malicious intent and resulting in unreliable or overly noisy detections.

Solution

Create a methodology that uses the surrounding context of a detection event to infer the intent of the actor, thus removing the ambiguity.

Impact

Reduce false positives and improve detection accuracy so defenders can prioritize the alerts that truly matter.
