We sh*t you not; Smart toilet hacked

Now you have seen it all. Trustwave has discovered that you can hack the Satis Smart Toilet.

The "My Satis" Android application has a hard-coded Bluetooth PIN of "0000" as can be seen in the following line of decompiled code from the application:

BluetoothDevice localBluetoothDevice =
BluetoothManager.getInstance().execPairing(paramString, "0000")

As such, any person using the "My Satis" application can control any Satis toilet. 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.

Apparently Satis doesent give a sh*t (sorry, too easy) according to Trustwaves logs:
