Atomics: [T1134.004](https://github.com/redcanaryco/atomic-red-team/blob/master/atomics/T1134.004/T1134.004.md)
Detects parent PID spoofing through Cross Process indicators (SrcProcParentName limits scope heavily) as well as detecting the use of PPID-Spoof powershell script through Command Scripts indicators. Update the `TgtProcName` list to filter noise.
```
(TgtProcRelation = "not_in_storyline" AND EventType = "Open Remote Process Handle" AND SrcProcParentName In Contains Anycase ("userinit.exe","powershell.exe","cmd.exe") AND TgtProcName != "sihost.exe" And TgtProcIntegrityLevel != "LOW" AND TgtProcName Not In ("SystemSettings.exe")) OR (SrcProcCmdScript ContainsCIS "PPID-Spoof" AND SrcProcCmdScript ContainsCIS "hSpoofParent = [Kernel32]::OpenProcess")
```

### T1574.009 Unquoted Service Path for program.exe
Atomics: [T1574.009](https://github.com/redcanaryco/atomic-red-team/blob/master/atomics/T1574.009/T1574.009.md)
Detects creation or modification of the file at `C:\program.exe` for exploiting unquoted services paths of Program Files folder.
```
(FileFullName = "C:\program.exe" AND EventType In ("File Creation","File Modification")) OR TgtProcImagePath = "C:\program.exe"
```
### T1055.012 Process Hollowing
Atomics: [T1055.012](https://github.com/redcanaryco/atomic-red-team/blob/master/atomics/T1055.012/T1055.012.md)
Detect Process Hollowing using the Start-Hollow powershell script, through CommandLine and CommandScript indicators.
The `IndicatorCategory = "Injection"` has a lot of noise, but in the future a combination of `EventType = "Duplicate Process Handle" AND TgtProcRelation = "storyline_child"` joined with some `ChildProcCount` or `CrossProcCount` > 0 may help filter the noise.
```
--- Detect Start-Hollow.ps1 by command or content
(SrcProcCmdScript ContainsCIS "Start-Hollow" AND SrcProcCmdScript ContainsCIS "[Hollow]::NtQueryInformationProcess") OR TgtProcCmdLine ContainsCIS "Start-Hollow"
```
### T1055 Process Injection
Atomics: [T1055](https://github.com/redcanaryco/atomic-red-team/blob/master/atomics/T1055/T1055.md)
Detects Process Injection through execution of MavInject, filtering out noisy/expected activity. `SrcProcParentName` filter narrows Cross Process items to HQ results.
```
(TgtProcName = "mavinject.exe" AND TgtProcCmdLine ContainsCIS "/injectrunning") AND (SrcProcName Not In ("AppVClient.exe") AND SrcProcParentName Not In ("smss.exe"))
```
