MITRE reference S0348
Cardinal RAT contains watchdog functionality that periodically ensures HKCU\Software\Microsoft\Windows NT\CurrentVersion\Windows\Load is set to point to its executable.3
Cardinal RAT and its watchdog component are compiled and executed after being delivered to victims as embedded, uncompiled source code.4
Cardinal RAT encodes many of its artifacts and is encrypted (AES-128) when downloaded.5
Cardinal RAT can collect the username from a victim machine.6
Cardinal RAT injects into a newly spawned process created from a native Windows executable.7
Standing S0348
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.

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.
