Standing G0128
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
Techniques2965th pct
65th percentile · 65% of 176 ATT&CK groups have this many Enterprise techniques or fewer.
Tactics1166th pct
66th percentile · 66% of 176 ATT&CK groups have this many tactics spanned or fewer.
Tools & malware0Bottom 9%
9th percentile · 91% of 176 ATT&CK groups have more tools and malware.
Campaigns089% tie · 4 values
89% of the population shares a single value across only 4 distinct values, so a percentile here would rank the tie, not the entity.
