Security Flaw in mAadhar App can Allow Hackers to Steal Your Aadhar Data

The app is saving user sensitive data, including the biometric data in a password protected the local database

A security researcher, alias, Elliot Alderson, has tweeted a serious security vulnerability in UIDAI’s mAadhaar app for Android devices.

According to the researcher, the app is saving user sensitive data, including the biometric data in a password protected the local database. The password for the database is generated using a random number “123456789 as seed” and a hardcoded string db_password_123 which remains same for every phone.

Besides this, Elliot has also uploaded a proof-of-concept on Github to demonstrate the flaw. He made an application with the exact same code as it was written in the Aadhar app to prove that even if you run it multiple times, it will give you the same password over and over again instead of the randomised password the app is supposed to generate.

The researcher has stated that if a person is able to crack the password, he/she can access the entire Aadhar account details of the user. He further said that as per the documentation for the mAadhaar app,  the app will store personal details and the user’s photo in their local database.

UIDAI has however confirmed that the app creates a local database with innocuous data like user preferences. Further, they said that since the app doesn’t ask for any biometric data, such data can’t be compromised.

Ankush Johar, director at Infosec Ventures, said: "Although the exploitability of this issue is pretty low, nonetheless, information as critical as Biometrics along with other PII is something that should not be exposed to even the slightest risk.

"Recently, with alleged leakage of Aadhaar details of over a billion citizens,  hackers might already have access to every information printed on our Aadhar cards and can easily replicate it.

"Even though a person has replicated your Aadhar card, he/she will still need your Biometric info for authentication. If by any chance the hackers are able to gain the biometric data as well, then it will catastrophic.

"As the UP cloning fraud showed us that making a physical clone of the fingerprints is not too difficult, such leakage could do irreversible damage as you can change your passwords but you cannot change your fingerprints."
