Turn it on or off
Most of our computers have a Wake-on-LAN feature, which means as long as the computer is plugged in to a network port, we can see it. Even if it's off. And we can send a command that will will turn it on. Once it's on, it's even easier to turn it off.
We have this term in IT called "Domain Admin." In layman terms, it's G-d Mode. Having that level of security permissions means a support grunt can go into anyone's folders and take/look/delete anything they want. Now, not everybody is a domain admin. But enough people are to make things scary.
Through a slew of different programs, we can see anything on anybody's screen, whenever we want, for however long we want to. And you'll never know we were there.
The ability to see everything comes with the ability to control any desktop as well. Microsoft calls it "Remote Assistance." I call it "Remote Superpowers."
The best part about all this is not that we can literally force this company to its knees if we so desired. It's that the entire time we were doing it, you would have no idea.
And don't make us angry.
But honestly, this is what we really do.
