title: Windows Process Dumping via sqldumper.exe with 0x0110 Command-Line Flags
id: 2492ad2e-d9ba-40fc-92d2-4552b305432d
status: test
description: This rule identifies execution of sqldumper.exe where the command line contains specific hex flags associated with process dumping behavior. Attackers may use this legitimate SQL Server utility to extract memory from running processes, supporting credential access and other post-compromise activities. Detection relies on Windows process creation telemetry, matching the executable name ending in \sqldumper.exe and the presence of the configured command-line strings.
