The OsInfo function in Komplex collects a running process list.4
The Komplex trojan creates a persistent launch agent called with $HOME/Library/LaunchAgents/com.apple.updates.plist with launchctl load -w ~/Library/LaunchAgents/com.apple.updates.plist.7
The Komplex payload is stored in a hidden directory at /Users/Shared/.local/kextd.8
Standing S0162
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
Techniques733rd pct
33rd percentile · 67% of 825 ATT&CK software entries have more Enterprise techniques.
Tactics541st pct
41st percentile · 59% 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.
