I had this idea for a fictional scenario in which a forgotten satellite, like a communications satellite that was decommissioned because it was replaced by a newer model, was hacked into and then smashed into another satellite.
And then I realized I have no idea what happens to high-altitude satellites when they are no longer used. Are they completely shut down so that communication with them is no longer possible? I assume communications are secure, passwords and cryptography and stuff, but are they monitored so that hacking attempts would be detected? If they are decommissioned with some fuel left, are they still parked up there or will they be deorbited? Are any satellites, in fact, ever decommissioned before they run out of fuel? Nothing I've read has seemed to quite cover any of that.

If the satellite is close to the Earth, a last bit of fuel is used to de-orbit it so that it burns up. If it is farther out, it is moved to a retirement orbit out beyond the used orbits.
The last thing done after moving it to the retirement orbit is to permanently disable the communication system so that it doesn't randomly transmit stuff and put noise on the communication frequencies.
Here is a Wikipedia article on GOES2 that mentions that the communication system was permanently disabled when the satellite was retired.

Okay, so deactivating communications is something that is done. It's interesting that the article says the weather satellite was "placed into storage" in 1993 and then reactivated as a communications satellite in 1995. I didn't know they could change careers like that.
