I was hacked, wasn't I?

So I didn't even know about the Screen Sharing controls in the OS until I had to set up a VPN for a new job. I was sort of freaked out to check the prefs and see this. None of those numbers or emails are familiar. They sound like Chinese names. Obviously I turned off the sharing after seeing this.

I was almost definitely hacked at some point, wasn't I? I've had my iMac since 2013 and thought I was being pretty good about checking my security prefs. This makes me think I either missed something or there was some exploit that it had for a while and then was hopefully patched at some point. I've obviously thought I turned off any kind of screen sharing access since I never have reason to share my screen.

I've definitely come home to see my machine oddly awake and w/o the screen saver on a few times over the years. I didn't see any odd icons on the menu bar, but can't say for sure. Is there possibly a log of some kind?

Uh, nope.

The block list is shared by all the Apple's app, so you probably blocked someone on your iPhone on in Messages.
And how is someone being blocked correlates to being hacked?

I'd turn screen sharing OFF (permanently), then run MalwareBytes...

Uh, because there was something set on my machine that I didn't directly set on my machine with contact information I don't recall. That's why. I don't see how that seems irrational.

But thanks nonetheless for the info that this is connected to the blocks I've done on my phone. Yes, one is a local business that blasts out voicemail ads (yeah, old school), and I suppose the unrecognized e-mails might have been blocks of text message spam, though I'm surprised I don't have more of those.

Also appreciate the pointer to MalwareBytes. I'll have a look there.

Relieved I won't have to spend the week changing passwords and credit cards!

You weren't hacked. Hackers don't hack people like you (nor I), they hack companies, banks, government installations—basically, you're not a challenge to them.

Just because something is happening that you don't understand, doesn't mean you were hacked.
