From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Have you considered some form of CI? I.e: Spin up a VM, run the script, reboot, report what changed? Might be a little expensive, but could help auditing?
I have, but I think it would be a bit too expensive on my VPS, but might use it if my site ever catches on. I have also considered using something like Try, but it isn't a full sandbox.
Very understandable. And from a security standpoint not necessarily indicitive of anything. A good malicious script would just check its environment first.
Would it know if it was a VM? I think KVMs can host only the kernel if I'm not mistaken
I think you can detect when your in a VM, not sure exactly how though. But they could even be checking for other environment factors, like network addresses, system language, or timezone details.
