Threat hunting frameworks: where does execution break down in practice?

TL;DR: Threat hunting frameworks such as PEAK, TaHiTI and MITRE ATT&CK stall when evidence is fragmented across SIEM, EDR and data lakes, forcing analysts into manual query translation and correlation that consumes the execute phase, according to Crogl. That bottleneck turns sound methodology into incomplete coverage unless teams change how they access and document evidence.

Key questions

Q: What breaks when threat hunting data is split across multiple systems?

A: The hunt often breaks in the execute phase.

Q: When should teams prioritise federated search over data normalisation for hunting?

A: Prioritise federated search when the primary problem is investigative speed and fidelity, not long-term warehousing.

Q: How do you know if an AI-powered threat hunting programme is working?

A: A good programme shortens investigation time, improves hunt hypotheses, and leads to detections that map to proven attacker paths.

Practitioner guidance

• Define hunt success by time-to-evidence Measure how many minutes of each hunt are spent on collection versus analysis, and treat a high collection share as a program risk.
• Prioritise cross-system query access Enable analysts to query SIEM, EDR and data lake sources from one investigation workflow so the same hypothesis does not need three separate translations.
• Preserve evidence in native format Avoid forcing every telemetry source into a single normalised schema when source-specific fields are needed for correlation or attribution.

Bottom line: Threat hunting frameworks can be correct in design and still underperform when evidence is too fragmented to analyse within the hunt window.
