macOS.OSAMiner is a Monero mining trojan that was first observed in 2018; security researchers assessed macOS.OSAMiner may have been circulating since at least 2015. macOS.OSAMiner is known for embedding one run-only AppleScript into another, which helped the malware evade full analysis for five years due to a lack of Apple event (AEVT) analysis tools.[1][2]

Standing S1048
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
Techniques1151st pct
51st percentile · 51% of 825 ATT&CK software entries have this many Enterprise techniques or fewer.
Tactics768th pct
68th percentile · 68% of 825 ATT&CK software entries have this many tactics spanned or fewer.
Threat groups061% 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.
