NamedPipeMaster – A Comprehensive Toolkit For Named Pipe Analysis And Interaction

NamedPipeMaster is a versatile tool for analyzing and monitoring in named pipes.

It includes Ring3NamedPipeConsumer for direct server interaction, Ring3NamedPipeMonitor for DLL-based API hooking and data collection, and Ring0NamedPipeFilter for comprehensive system-wide monitoring.

The tool supports proactive and passive interactions, collects detailed communication data, and features a filter for specific event searches.

Features

  • Named Pipe Interaction:
    • Proactive Interaction: Actively interact with a named pipe server.
    • Passive Connection: Be passively connected by a named pipe client.
    • Proxy Interaction: Inject a DLL into a process to serve as a proxy for interacting with a named pipe server.
  • Information Collection via DLL Injection (Ring3 Hook):
    • Monitors and collects information on named pipe communication by hooking relevant APIs.
    • Dumps the call stack in detoured functions and checks the process’s impersonation capability.
    • Specific API hooks include:
      • NtCreateNamedPipeFile: Named pipe creation.
      • NtCreateFile: Named pipe connection.
      • NtFsControlFile: Named pipe connection completion.
      • NtReadFile: Reading data from a named pipe.
      • NtWriteFile: Writing data to a named pipe.
  • System-Wide Monitoring with Minifilter Driver:
    • Captures system-wide named pipe activities by monitoring key IRPs (I/O Request Packets):
      • IRP_MJ_CREATE_NAMED_PIPE: Named pipe creation.
      • IRP_MJ_CREATE: Named pipe connection.
      • IRP_MJ_FILE_SYSTEM_CONTROL: Named pipe connection completion.
      • IRP_MJ_READ: Reading data from a named pipe.
      • IRP_MJ_WRITE: Writing data to a named pipe.

Usage

Put Ring3NamedPipeConsumer.exe, Ring3NamedPipeMonitor.dll, and Ring0NamedPipeFilter.sys in the same directory and run Ring3NamedPipeConsumer.exe.

Watch the demo video to understand the detailed usage. Please ensure that code integrity is disabled to use the features of the minifilter driver.
