It may not have the popularity of brands such as Ring, Netatmo or Nest, but Wyze is one of those companies that can boast selling millions of devices for the Internet of Things.

The economic products of this Chinese firm are popular among home automation enthusiasts, who have now recognized the leaking of potentially sensitive information associated with more than two million customers.

As confirmed by the co-founder of Wyze Dongsheng Song, the data in question includes the email addresses used to create a Wyze account, the user names assigned to the Wyze security cameras and the SSID identifiers of the Wi-Fi networks of 2.4 million users were filtered.

In addition, the Alexa tokens used to connect the voice assistant to the devices of 24,000 people were also filtered. All that information remained exposed for 22 days.

In a message posted on the company's official forums, Song indicates that the company "copied some data from the main production servers and put them in a more flexible and easily searchable database.

This new data table was protected at the time of its creation. However, a Wyze employee made a mistake on December 4 when using this database and the security protocols for that data were removed.

The data in question was sent to an Alibaba Cloud server in China in which there was a similar leak six months ago without Wyze acknowledging it publicly, which is why he did not provide a notice to the company, but publicly reported the event. The co-founder of Wyze, meanwhile, says the company does not use Alibaba Cloud and that there was no previous leak.

12Security states that the information hosted on the insecure server contained data such as weight, height, sex, bone density and mass, protein intake "and other health information" from a group of users who would have used smart scales of the company. Song has denied that its products maintain records in the cloud about bone density or protein intake, but does not deny in its message that it is capturing other factors such as the user's gender, weight and height.

In his message on the official forums, Song apologizes and promises to learn from his mistakes, but not before pointing out that "it is not true" that the safety of Wyze's products lives up to its reduced price.
