Who said the field of security cannot have humour! An Android app to control the commode in Japan (you know the land of fully programmable toilets, I kid you not) has announced a vulnerability because the bluetooth pairing code is hardcoded.
The alert goes:
An attacker could simply download the “My Satis” application and use it to cause the toilet to repeatedly flush, raising the water usage and therefore utility cost to its owner. Attackers could cause the unit to unexpectedly open/close the lid, activate bidet or air-dry functions, causing discomfort or distress to user.
