A huge MongoDB database exposing 275,265,298 records of Indian citizens containing detailed personally identifiable information (PII) was left unprotected on the Internet for more than two weeks. The exposed data included information such as name, gender, date of birth, email, mobile phone number, education details, professional info (employer, employment history, skills, functional area), and current salary for each of the database records. The database remained open and searchable until today, May 8th, when it got dropped by hackers known as ‘Unistellar’ group.
