Nah, the horror comes from how much data people leak online.

If it's worth $3 to you, I recommend "Take This Lollipop".

It used to be free, but I guess they gotta eat too.

It's basically a creepy interactive movie that uses a person's own personal data to scare them about privacy and what they put on the net.

People were close, but what you actually want is OpenCanary. It fakes SSH and Samba services and can be configured to alert you when triggered.
