Standing G0005
Reach is how much of ATT&CK this group touches. Coverage is how well defended each thing it does is, as a median per technique rather than a total — a total would just restate the reach. Each figure is ranked against all 176 ATT&CK groups only where that population actually spreads. Where most of the population shares one value, a percentile would rank the tie instead of the entity, so the raw value is shown and no rank is claimed.
Reach
16th percentile · 84% of 176 ATT&CK groups have more Enterprise techniques.
13th percentile · 87% of 176 ATT&CK groups have more tactics spanned.
47th percentile · 53% of 176 ATT&CK groups have more tools and malware.
89% of the population shares a single value across only 4 distinct values, so a percentile here would rank the tie, not the entity.
Coverage
91st percentile · 91% of 176 ATT&CK groups have this many detection rules per technique or fewer.
Detection coverage G0005
165 distinct rules cover the 5 techniques recorded for this group. The 176 technique-to-rule mappings resolve to 165 distinct rules, because one rule can cover several techniques. 94 Sigma · 71 Splunk.
