Dismissing the claims, the government said "no personal information of any user has been proven to be at risk by this ethical hacker".
"We are continuously testing and upgrading our systems. Team Aarogya Setu assures everyone that no data or security breach has been identified," the government said through the app's Twitter handle.
The tweet gave point-by-point clarification on the red flags raised by the hacker.
A security issue has been found in your app. The privacy of 90 million Indians is at stake. Can you contact me in private?
PS: @RahulGandhi was right

The app fetches users' location and stores on the server in a secure, encrypted, anonymised manner - at the time of registration, at the time of self assessment, when users submit their contact tracing data voluntary through the app or when it fetches the contact tracing data of users after they have turned Covid-19 positive, it said.
Statement by Aarogya Setu app team
On another issue that users can get Covid-19 stats displayed on the home screen by changing the radius and latitude-longitude using a script, Aarogya Setu said that all this information is already public for all locations and hence does not compromise on any personal or sensitive data.
"We thank the ethical hacker on engaging with us. We encourage any users who identify a vulnerability to inform us immediately...," it said.
Responding to Aarogya Setu's clarification, Alderson tweeted, "I will come back to you tomorrow".
