I've never come home to an unexpected plumber, but did have a greyhat "fix" my stuff once, and wasn't outraged at all. It felt like an intrusion, but I was grateful. In ~ 2002 I was off to college with my Linux workstation. IIRC, the vulnerability was in the CUPS web UI. Someone filled the volume with a giant /tmp/YOUR_SYSTEM_IS_INSECURE_UPDATE_NOW file, and shutdown the affected service. It could have been much worse.
