What is the issue you’re encountering

Files are “accessed” without my knowledge.

What steps have you taken to resolve the issue?

None. Don’t know what to do.

What are the steps to reproduce the issue?

I am using a cloudflared tunnel to server up my web server to the internet. Because of that I have been worried lately about how cloudflare has a bad reputation for being used by hackers to get into computers. While using my computer I noticed that a file was opened that I don’t remember opening. I did do an OS update on my computer recently but I don’t see how that would show me a file I haven’t opened in a long time.

When I use…

ls -lu "/path_to/some_file/on_my_computer.txt"

… on files in one of my folders they tell me that the files were accessed the around the same minute as the other files on my computer… (I know for a fact it wasn’t me that accessed it)

-Question-

Is this indicative of Malware that is scanning my file system? Perhaps using a cloudflare tunnel or other means to exfiltrate data from my computer without my knowledge?

Could it be some innocent background process of my macOS computer?
