A CIS report titled "Information Security Practices of Aadhaar (or lack thereof): A Documentation of Public Availability of Aadhaar Numbers with Sensitive Personal Financial Information'. has claimed that millions of Indians could be the victim of a data breach.
While it's not clear whether this is an actual breach or potential breach, it highlights a weakness, or complete lack of IT Security controls in protecting the databases.
This is a particular challenge for growing economies that are rapidly adopting digital technologies, but lack security and privacy frameworks to adequately support the infrastructure.
Aadhaar numbers and personal information of as many as 135 million Indians could have been leaked from four government portals due to lack of IT security practices, the Centre for Internet and Society has claimed. "Based on the numbers available on the websites looked at, estimated number of Aadhaar numbers leaked through these four portals could be around 130-135 million," the report by CIS said.
