A massive database containing over 275 million records with personally identifiable information about Indian citizens was allegedly found unprotected and publicly indexed on the Internet. Discovered by a cybersecurity expert, this MongoDB database seems to include data scrapped from various job portals, given the fields in the database like “industry,” “resume ID,” and “functional area.” While some of professional information present in the database isn't that damaging, the database also included details like name, email address, gender, date of birth, salary, and mobile number, access to which can be exploited by malicious parties. MongoDB is a widely used open-source database management system.
Found by security researcher Bob Diachenko from Securitydiscovery.com on May 1, the database has since been hijacked by hackers known as “Unistellar group”, who have replaced it with a message to contact to restore it, possibly in an exchange of a ransom. If the database being left unprotected wasn't bad enough, it is now in hands of a hacker group, who may be willing to sell it to anyone.
According to Diachenko, he had immediately contacted Indian Computer Emergency Response Team (CERT) about the unprotected database, but the database remained accessible until May 8, following which it was hijacked by the Unistellar group.
The data available with Shodan, a search engine for Internet-connected devices, reveals that the database was first indexed on April 23, 2019, meaning it was available on the Web for at least two weeks for anyone to access the private information.
It is unclear at this point, who was the owner of the database, but Diachenko speculates that it belonged to an “anonymous person or organization” as part of a massive scraping operation. The owners of the database have seemingly managed to scrap over 275,265,298 records of personal information about Indian job seekers. Diachenko's assertions about database owner seem plausible considering none of Indian job portals, have anywhere close to 275 million members.
This is not the first time that Diachenko has found an unprotected database leaking private information of millions of users online. Last month, he discovered an Indian state (unnamed) had left details of millions of pregnant women online. The data leak included digitised version of millions of medical forms that included private details.
