function Get-SysmonCreateRemoteThreadEvent { <# .SYNOPSIS Get Sysmon Remote Thread Creation events (EventId 8). .DESCRIPTION The CreateRemoteThread event detects when a process creates a thread in another process. This technique is used by malware to inject code and hide in other processes. The event indicates the source and target process. It gives information on the code that will be run in the new thread: StartAddress, StartModule and StartFunction. Note that StartModule and StartFunction fields are inferred, they might be empty if the starting address is outside loaded modules or known exported functions. .EXAMPLE PS C:\> Get-SysmonCreateRemoteThreadEvent -SourceImage 'C:\Windows\System32\wbem\WmiPrvSE.exe' -Suppress Find all events where the API CreateRemoteThread was used and the process image was not WmiPrvSE.exe. .INPUTS System.IO.FileInfo .OUTPUTS Sysmon.EventRecord.CreateRemoteThread .NOTES https://www.ultimatewindowssecurity.com/securitylog/encyclopedia/event.aspx?eventid=90008 #> [CmdletBinding(DefaultParameterSetName = 'Local')] param ( # Log name for where the events are stored.
