When you run a major app, all it takes is one mistake to put countless people at risk. Such is the case with Diksha, a public education app run by India’s Ministry of Education that exposed the personal information of around 1 million teachers and millions of students across the country. The data, which included things like full names, email addresses, and phone numbers, was publicly accessible for at least a year and likely longer, potentially exposing those impacted to phishing attacks and other scams.
