With the name Smarter, you might expect a network-connected kitchen appliance maker to be, well, smarter than companies selling conventional appliances. But in the case of the Smarter’s Internet-of-things coffee maker, you’d be wrong.
Security problems with Smarter products first came to light in 2015, when researchers at London-based security firm Pen Test partners found that they could recover a Wi-Fi encryption key used in the first version of the Smarter iKettle. The same researchers found that version 2 of the iKettle and the then-current version of the Smarter coffee maker had additional problems, including no firmware signing and no trusted enclave inside the ESP8266, the chipset that formed the brains of the devices. The result: the researchers showed a hacker could probably replace the factory firmware with a malicious one. The researcher EvilSocket also performed a complete reverse engineering of the device protocol, allowing remote control of the device.
Two years ago, Smarter released the iKettle version 3 and the Coffee Maker version 2, said Ken Munro, a researcher who worked for Pen Test Partners at the time. The updated products used a new chipset that fixed the problems. He said that Smarter never issued a CVE vulnerability designation, and it didn’t publicly warn customers not to use the old one. Data from the Wigle network search engine shows the older coffee makers are still in use.
