PR3TACK: The Preemptive Tactics & Countermeasures Knowledgebase

The Preemptive Tactics & Countermeasures Knowledgebase (PR3TACK) is an openly accessible framework designed to catalogue *plausible but unobserved* adversary tactics, techniques, and procedures (TTPs). Whereas existing knowledge bases such as MITRE ATT&CK and MITRE D3FEND are constructed retrospectively from observed adversarial activity, PR3TACK seeks to bridge the anticipatory gap. It provides a structured means of conceptualising techniques that adversaries could plausibly develop and deploy, based on the convergence of known system vulnerabilities, adversarial innovation patterns, and technological affordances. In so doing, PR3TACK offers defenders a strategic advantage: the ability to harden environments preemptively, before exploitation occurs. This paper outlines the rationale, structure, and prospective impact of PR3TACK, situating it within ongoing debates about proactive defence, resilience engineering, and the epistemology of cyber threat intelligence.
