APT29 is threat group that has been attributed to Russia's Foreign Intelligence Service (SVR).[1][2] They have operated since at least 2008, often targeting government networks in Europe and NATO member countries, research institutes, and think tanks. APT29 reportedly compromised the Democratic National Committee starting in the summer of 2015.[3][4][5][6]
In April 2021, the US and UK governments attributed the SolarWinds Compromise to the SVR; public statements included citations to APT29, Cozy Bear, and The Dukes.[7][8] Industry reporting also referred to the actors involved in this campaign as UNC2452, NOBELIUM, StellarParticle, Dark Halo, and SolarStorm.[9][10][11][12][13][14]

Standing G0016
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
92nd percentile · 92% of 176 ATT&CK groups have this many Enterprise techniques or fewer.
85th percentile · 85% of 176 ATT&CK groups have this many tactics spanned or fewer.
100th percentile · None of the 176 ATT&CK groups has more tools and malware — the highest in the population.
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
28th percentile · 72% of 176 ATT&CK groups have more detection rules per technique.
Detection coverage G0016
1781 distinct rules cover the 66 techniques recorded for this group. The 2056 technique-to-rule mappings resolve to 1781 distinct rules, because one rule can cover several techniques. 1099 Sigma · 682 Splunk.
