A posh toilet that washes your bottom could be hijacked by pranksters, security experts say.
Satis toilets have a built-in wash nozzle that is activated by a smartphone app - but anybody with the app can activate any of the toilets.
Pranksters could squirt water at your bottom whilst you're on the toilet!
"A practical joker might be able to trick his neighbours into thinking his toilet is possessed," said security expert Graham Cluley.
Spending 380,000 pennies
Satis toilets cost about £3,800 and also have a built-in music player, perfume spray and bum-dryer!
But the Bluetooth password for the toilet can't be changed, so anybody with the app can activate the loo's features remotely.
Luckily Bluetooth only has a short range so a prankster would need to be fairly close to the toilet to unleash such mischief.
Graham told the BBC there were unlikely to be serious consequences from the toilet's flaw.
"It's hard to imagine how serious hardened cybercriminals would be interested in this security hole," said Graham.
