luxury toilet controlled by a smartphone app is vulnerable to attack, according to security experts.
Retailing for up to $5,686 (£3,821), the Satis toilet includes automatic flushing, bidet spray, music and fragrance release.
The toilet, manufactured by Japanese firm Lixil, is controlled via 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 reveals.
"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," it says in its report.
