Summary
The WinRM Tools detection rule is designed to monitor for suspicious utilization of Windows Remote Management (WinRM), which is often leveraged in lateral movement techniques by threat actors. WinRM is a command-line tool that allows for remote management of Windows systems, and this rule specifically tracks interactions through WinRM, Winrs, and WMI command-line interfaces. It utilizes indexed logs related to PowerShell executions to capture instances where these tools are invoked, filtering the results for cases where there are fewer than 25 unique processes over a 1-second interval. The presence of this rule is particularly relevant given the association with various threat actors and malware groups known to exploit these protocols, indicating potential compromise or reconnaissance activities within a network. The rule implements techniques identified as T1021.006 (Remote Services: Windows Remote Management) and T1047 (Execution: Windows Management Instrumentation), aligning with common behavior observed in advanced persistent threats (APTs) and sophisticated cybercriminal operations.
