Luxury toilet users warned of app flaw

A luxury toilet that is controlled by a smartphone app is vulnerable to attack, according to security experts.

The Satis toilet incorporates automatic flushing, bidet spray, music and fragrance release. Manufactured by Japanese firm Lixil it sells for up to 4,200 euros and is controlled by an Android app called My Satis.

But a hardware flaw means any phone with the app could activate any of the toilets, researchers say.

The toilet uses bluetooth to receive instructions via the app, but the Pin code for every model is hardwired to be four zeros (0000), meaning that it cannot be reset and can be activated by any phone with the My Satis app, a report by Trustwave's Spiderlabs information security experts says.

"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," states the report.

"Attackers could [also] cause the unit to unexpectedly open/close the lid, activate bidet or air-dry functions, causing discomfort or distress to [the] user."

The limited range of bluetooth means that anyone wishing to carry out such an attack would need to be fairly close to the toilet itself, said security expert Graham Cluley.

"Although this vulnerability seems largely harmless, what's clear is that companies building household appliances need to have security in mind just as much as computer manufacturers."
