Standing G1033
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
53rd percentile · 53% of 176 ATT&CK groups have this many Enterprise techniques or fewer.
59th percentile · 59% of 176 ATT&CK groups have this many tactics spanned or fewer.
23rd percentile · 77% 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
7th percentile · 93% of 176 ATT&CK groups have more detection rules per technique.
Detection coverage G1033
286 distinct rules cover the 20 techniques recorded for this group. The 303 technique-to-rule mappings resolve to 286 distinct rules, because one rule can cover several techniques. 161 Sigma · 125 Splunk.
