This should come as no surprise, but it still sucks big-time: thousands of people who downloaded a random, very popular app called WiFi Finder found that it got handsy with users’ own home Wi-Fi, uploading their network passwords to a database full of 2 million passwords that was found exposed and unprotected online.

The leaked database was discovered by Sanyam Jain, a security researcher and a member of the GDI Foundation who reported his find to TechCrunch. Jain and TechCrunch’s Zack Whittaker spent more than two weeks fruitlessly trying to contact the developer, who they believe is based in China.

Receiving no reply, they instead turned to the host, DigitalOcean, which yanked the database within a day of their contact.

According to the app’s Google Play listing, it’s been installed more than 100,000 times.

The app does what it says it does: it searches for nearby hotspots, maps them, and enables users to upload all their stored Wi-Fi passwords. Unfortunately, in spite of what the app developer – Proofusion – claims, WiFi Finder doesn’t differentiate between public hotspots and what Whittaker says are the “countless” home Wi-Fi networks found by TechCrunch and Jain.

The exposed database didn’t give away contact information for any of the Wi-Fi network owners, but it did include geolocation data. The geolocations often corresponded to what look like wholly residential areas where there don’t appear to be any businesses, suggesting that the logins are for home networks.
