ID Data Source Data Component Detects; DS0017: Command: Command Execution: Monitor executed commands and arguments that may configure system settings to automatically execute a program during system boot or logon to maintain persistence or gain higher-level privileges on compromised systems. G0143 : Aquatic Panda Remote access tools with built-in features may interact directly with the Windows API to gather information. Added "Creator Process Name" field. One of the well-known ways of managing printers in different versions of Windows is the host process rundll32.exe, which receives the name of the library printui.dll and the entry point to it (PrintUIEntry).The command rundll32 printui.dll,PrintUIEntry is enough to perform basic operations with printers and is fully supported by Microsoft, but the use of Actions may be related to network and system information Discovery, Collection, or other scriptable post-compromise behaviors and could be used as indicators of detection leading back to the source script. Looking at the Actions tab tells us the actual command line, which uses the rundll32.exe component to run the Windows.Storage.ApplicationData.dll file, and calls the CleanupTemporaryState function within that DLL. Network Traffic Flow: Monitor network data for uncommon data flows. To start Synchronize dirs and compare folders right away, use this syntax: The redirection operator > must be escaped with caret character ^ on FOR command line to be interpreted as literal character when the Windows Command Processor parses this command line before executing the command FOR which executes the embedded dir command line with using a separate command process started in background.
