Popular virtual keyboard app leaks 31 million users' personal data

(CBS) Personal data belonging to over 31 million customers of a popular virtual keyboard app has leaked online, after the app's developer failed to secure the database's server.

The server is owned by Eitan Fitusi, co-founder of AI.type, a customizable and personalizable on-screen keyboard, which boasts more than 40 million users across the world.

But the server wasn't protected with a password, allowing anyone to access the company's database of user records, totaling more than 577 gigabytes of sensitive data.

The database appears to only contain records on the app's Android users.

The discovery was found by security researchers at the Kromtech Security Center, which posted details of the exposure alongside ZDNet. The data was only secured after several attempts to contact Fitusi, who acknowledged the security lapse this weekend. The server has since been secured, but Fitusi did not respond when we asked for comment.

ZDNet obtained a portion of the database to verify.

Each record contains a basic collected data, including the user's full name, email addresses, and how many days the app was installed. Each record also included a user's precise location, including their city and country.

Other records are significantly more detailed. The app has a free version, which per its privacy policy collects more data than the paid version, which the company uses to monetize with advertising.

More complete records also include the device's IMSI and IMEI number, the device's make and model, its screen resolution, and the device's specific Android version.

A large portion of the records also included the user's phone number and the name of their cell phone provider, and in some cases their IP address and name of their internet provider if connected to Wi-Fi. Many records contain specific details of a user's public Google profile, including email addresses, dates of birth, genders, and profile photos.

We also found several tables of contact data uploaded from a user's phone. One table listed 10.7 million email addresses, while another contained 374.6 million phone numbers. It's not clear for what reason the app uploaded email addresses and phone numbers of contacts on users' phones.

Several tables contained lists of each app installed on a user's device, such as banking apps and dating apps.
