Every technique, answered.

All 918 techniques in ATT&CK, each with one of three answers. Not every technique can be detected from logs, and saying so plainly is more useful than shipping a rule that never fires — so “we deliberately did not write this, and here is why” counts as covered ground here, not as a gap.

404Detection writtenA Sigma rule exists. Unverified unless it earned a lab badge.
125No distinct observableA reviewer read the telemetry and found nothing a sibling technique does not already cover. The reason is on the page.
389Not expressible in SigmaMobile, ICS, abstract data sources and API-hook telemetry. Sigma has no logsource for these.

Structurally out of reach

Nothing written for these 6, and why.

Not a backlog. Two different reasons, and neither is fixed by writing more rules.

  • Reconnaissance and Resource Development happen before the attacker touches you, on infrastructure they own. There is no event on your estate to write a rule against.
  • Mobile and ICS — the remaining four — have no Sigma logsource taxonomy at all, so there is no field name a rule could reference. That is why the authorable ceiling here is 529 techniques and not 918.
