"description": "A port monitor can be set through the (Citation: AddMonitor) API call to set a DLL to be loaded at startup. (Citation: AddMonitor) This DLL can be located in <code>C:\\Windows\\System32</code> and will be loaded by the print spooler service, spoolsv.exe, on boot. The spoolsv.exe process also runs under SYSTEM level permissions. (Citation: Bloxham) Alternatively, an arbitrary DLL can be loaded if permissions allow writing a fully-qualified pathname for that DLL to <code>HKLM\\SYSTEM\\CurrentControlSet\\Control\\Print\\Monitors</code>. The Registry key contains entries for the following:\n*Local Port\n*Standard TCP/IP Port\n*USB Monitor\n*WSD Port\n\nAdversaries can use this technique to load malicious code at startup that will persist on system reboot and execute as SYSTEM.\n\nDetection: * Monitor process API calls to (Citation: AddMonitor).\n* Monitor DLLs that are loaded by spoolsv.exe for DLLs that are abnormal.\n* New DLLs written to the System32 directory that do not correlate with known good software or patching may be suspicious.\n* Monitor Registry writes to <code>HKLM\\SYSTEM\\CurrentControlSet\\Control\\Print\\Monitors</code>.\n* Run the Autoruns utility, which checks for this Registry key as a persistence mechanism (Citation: TechNet Autoruns)\n\nPlatforms: Windows\n\nData Sources: File monitoring, API monitoring, DLL monitoring, Windows Registry, Process monitoring\n\nEffective Permissions: SYSTEM\n\nPermissions Required: Administrator, SYSTEM\n\nContributors: Stefan Kanthak, Travis Smith, Tripwire",
