What it detects

This rule identifies process image loads where the loaded DLL filename ends with one of several known SVR GraphicalProton-specific DLL names. Attackers commonly rely on DLL loading to execute or persist malicious functionality while blending into normal Windows activity. Detection depends on Windows image load telemetry that records the full loaded module path and allows matching the DLL name suffixes.
