  • Sysmon v6
    This release of Sysmon, a background monitor that records activity to the event log for use in security incident detection and forensics, introduces an option that displays event schema, adds an event for Sysmon configuration changes, interprets and displays registry paths in their common format, and adds named pipe create and connection events (thanks to Giulia Biagini for the contribution). Check out the related presentation from Mark’s RSA Conference, “ How to Go From Responding to Hunting with Sysinternals Sysmon.”
  • Autoruns v13.7

  • Sysmon v5
    This major update to Sysmon, a background monitor that records activity to the event log for use in security incident detection and forensics, introduces file create and registry modification logging. These event types make it possible to configure filters that capture updates to critical system configuration as well as changes to autostart entry points used by malware.
  • Process Explorer v16.20
    This release of Process Explorer, a powerful process management and diagnostic utility, adds reporting of process Control Flow Guard (CFG) status and dynamically updates to reflect changes to process Data Execution Prevention (DEP) configuration.
  • Procdump v8.2
    Procdump, a command-line utility that generates process dumps on demand or based on triggers that include memory, CPU, exception and performance counter thresholds, adds a -kill option that terminates a process after its dump completes rather than allowing an exception to pass to Windows Error Reporting (WER), and a -wer switch to copy dumps to the WER queue.
  • LiveKd v5.6
    LiveKd, a tool that enables interactive kernel debugger analysis of a live system or virtual machine, includes a batch-mode option designed for scripted analysis that omits the prompt to re-execute LiveKD after a debugger session terminates.
