ADFS DB Suspicious Named Pipe Connection
This rule detects suspicious connections to the ADFS database via named pipes. It specifically looks for processes connecting to the `\\MICROSOFT##WID\tsql\query` named pipe on ADFS servers, excluding legitimate ADFS-related processes such as `Microsoft.Identity.Health.Adfs.PshSurrogate.exe`, `Microsoft.IdentityServer.ServiceHost.exe`, `AzureADConnect.exe`, `Microsoft.Tri.Sensor.exe`, `wsmprovhost.exe`, `mmc.exe`, `sqlservr.exe`, and `sqlwriter.exe`. Such connections from unauthorized processes may indicate an attempt to access ADFS for malicious purposes.
