-
Identify installed Adobe Substance 3D Stager versionWindows: Open Programs and Features or check registry at HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\ for Adobe Substance 3D Stager. MacOS: Right-click Adobe Substance 3D Stager.app > Get Info or run: defaults read /Applications/Adobe\ Substance\ 3D\ Stager.app/Contents/Info CFBundleShortVersionStringAffected if Installed version is 2.0.1 or earlier (any version <= 2.0.1)
-

-
Verify application binary versionRight-click the executable file > Properties > Details tab to view File Version and Product VersionAffected if Product Version shows 2.0.1 or earlier
-
Check for recent file open activityReview recent .stager files opened by the user. On Windows: Check recent documents or TEMP folder for .stager files. On MacOS: Check ~/Documents or recent files accessed by the applicationAffected if User has opened .stager files from untrusted sources since vulnerability is triggered by parsing malicious files
