Researchers at vpnMentor say that an improperly-secured online database belonging to OneClass has left the private information of more than a million students exposed. The tool lets students share class notes and study guides.
vpnMentor researchers discovered the database while performing a series of routine Internet scans and estimates that the exposed OneClass database included nearly 9 million total records. Its total size was around 27GB, enough to store more than 2 million full pages of text.
Personal information included full names and email addresses, phone numbers, and course enrollment details with some likely to be linked to minors. OneClass allows users as young as 13 to register.
