valid check to detect process running on cloud VM vs local machine in mac

I m trying to identify if my launched process is running on a local mac machine(desktop/laptop) or a virtual macOS X instance like AWS EC2, Azure, MacStadium etc.

I am using the below check for this:

1 . If running on native Apple hardware, the returned value contains the model name of the hardware:

$ sysctl -n hw.model

Macmini8,1

On virtualized hardware, the value may contain the hypervisor name:

$ sysctl -n hw.model

VMware7,0

If the command output doesn't contain the "Mac" substring, the malware considers that it is running in a virtual machine.

2. Checking USB device vendor names

The commands used:

ioreg -rd1 -c IOUSBHostDevice | grep "USB Vendor Name"

Sample output on native Apple hardware:

"USB Vendor Name" = "Apple Inc."
"USB Vendor Name" = "Apple Inc."
"USB Vendor Name" = "Apple, Inc."

On virtualized hardware, the value may contain the hypervisor name:

"USB Vendor Name" = "VirtualBox"

"USB Vendor Name" = "VirtualBox"

A virtual machine can be detected by checking if the command output contains a hypervisor name, for example "VirtualBox", "VMware", etc.

3 . Checking the "IOPlatformExpertDevice" registry class

The command used:

ioreg -rd1 -c IOPlatformExpertDevice

The following fields of the IOPlatformExpertDevice class can be checked in order to detect a virtual machine:

I wanted to know can a combination of these be used to identify a process running on a Cloud VM with certainity?
