MITRE reference S0415
BOOSTWRITE has used the DWriteCreateFactory() function to load additional modules.3
BOOSTWRITE has used a a 32-byte long multi-XOR key to decode data inside its payload.4
BOOSTWRITE has been signed by a valid CA.5
BOOSTWRITE has exploited the loading of the legitimate Dwrite.dll file by actually loading the gdi library, which then loads the gdiplus library and ultimately loads the local Dwrite dll.6
Standing S0415
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
Techniques5Bottom 23%
23rd percentile · 77% of 825 ATT&CK software entries have more Enterprise techniques.
Tactics3Bottom 21%
21st percentile · 79% of 825 ATT&CK software entries have more tactics spanned.
Threat group161% tie · 22 values
61% of the population shares a single value across only 22 distinct values, so a percentile here would rank the tie, not the entity.
Campaigns085% tie · 8 values
85% of the population shares a single value across only 8 distinct values, so a percentile here would rank the tie, not the entity.
