Detection logic

`powershell` EventCode=4104 ScriptBlockText= "* Win32_PnPEntity *" ScriptBlockText= "*SELECT*" ScriptBlockText= "*WHERE*" ScriptBlockText = "*PNPClass*" ScriptBlockText IN ("*Image*", "*Camera*") 
| stats count min(_time) as firstTime max(_time) as lastTime by EventCode ScriptBlockText Computer UserID 
| rename Computer as dest 
| rename UserID as user 
| `security_content_ctime(firstTime)` 
| `security_content_ctime(lastTime)`
