APT37 is a North Korean state-sponsored cyber espionage group that has been active since at least 2012. The group has targeted victims primarily in South Korea, but also in Japan, Vietnam, Russia, Nepal, China, India, Romania, Kuwait, and other parts of the Middle East. APT37 has also been linked to the following campaigns between 2016-2018: Operation Daybreak, Operation Erebus, Golden Time, Evil New Year, Are you Happy?, FreeMilk, North Korean Human Rights, and Evil New Year 2018.[1][2][3]
North Korean group definitions are known to have significant overlap, and some security researchers report all North Korean state-sponsored cyber activity under the name Lazarus Group instead of tracking clusters or subgroups.

Standing G0067
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
65th percentile · 65% 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.
86th percentile · 86% of 176 ATT&CK groups have this many tools and malware or fewer.
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
88th percentile · 88% of 176 ATT&CK groups have this many detection rules per technique or fewer.
Detection coverage G0067
1107 distinct rules cover the 29 techniques recorded for this group. The 1206 technique-to-rule mappings resolve to 1107 distinct rules, because one rule can cover several techniques. 786 Sigma · 321 Splunk.
