The Kromtech Security Center has discovered a massive amount of customer files leaked online and publically available.

Researchers were able to access the data and details of 31,293,959 users. The misconfigured MongoDB database appears to belong to Ai.Type, a Tel Aviv-based startup that designs and develops a personalized keyboard for mobile phones and tablets for both Android and iOS devices.

Ai.Type accidentally exposed their entire 577GB Mongo-hosted database to anyone with an internet connection. This also exposed just how much data they access and how they obtain a treasure trove of data that average users do not expect to be extracted or datamined from their phone or tablet.

Besides phone books and contacts, also leaked were client files that included the personal details of 31,293,959 users that included phone numbers, full name of the owner, device name and model, mobile network name, SMS number, screen resolution, user languages enabled, Android version, IMSI number, IMEI number, emails associated with the phone, country of residence, links and the information associated with the social media profiles and photo, IP addresses, location details, and more.

In other words, just about everything.
