SUNBURST is a trojanized DLL designed to fit within the SolarWinds Orion software update framework. It was used by APT29 since at least February 2020.[1][2]
Enterprise ATT&CK only. Any Mobile or ICS rows on the same ATT&CK page are not carried.
MITRE reference S0559
SUNBURST C2 data attempted to appear as benign XML related to .NET assemblies or as a faux JSON blob.456
SUNBURST masqueraded its network traffic as the Orion Improvement Program (OIP) protocol.7
SUNBURST collected a list of service names that were hashed using a FNV-1a + XOR algorithm to check against similarly-hashed hardcoded blocklists.10

Standing S0559
Reach is how much of ATT&CK this tool 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 825 ATT&CK software entries 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
96th percentile · 96% of 825 ATT&CK software entries have this many Enterprise techniques or fewer.
80th percentile · 80% of 825 ATT&CK software entries have this many tactics spanned or fewer.
61% of the population shares a single value across only 22 distinct values, so a percentile here would rank the tie, not the entity.
85% of the population shares a single value across only 8 distinct values, so a percentile here would rank the tie, not the entity.
Coverage
40th percentile · 60% of 825 ATT&CK software entries have more detection rules per technique.
Detection coverage S0559
1221 distinct rules cover the 36 techniques recorded for this tool. The 1318 technique-to-rule mappings resolve to 1221 distinct rules, because one rule can cover several techniques. 810 Sigma · 411 Splunk.
