It Now Appears Possible to Hack a (Fancy, Japanese) Toilet (The Atlantic)
The information security company Trustwave Holdings published an advisory regarding Satis-brand toilets. Satis are a top-of-the-line product of LAXIL, one of Japan's largest commode companies, and they're advertised in the US with the tagline "SATIS defines toilet innovation."
And indeed! How innovative they definitionally are. For not only does the commode sport a broad set of features standard in Nipponese toilets -- deodorizing capabilities, an automatic seat, a two nozzle bidet spray -- but also it can be controlled by an Android app.
...
...According to Trustwave, every Satis toilet has the same hard-coded Bluetooth PIN, which means "any person using the 'My Satis' [Android] application can control any Satis toilet."
