Elliot Alderson: The hacker who started the Aadhaar security controversy

Despite UIDAI rubbishing claims that Sharma's personal details were stolen from the UIDAI database using his Aadhaar number, the episode isn't over yet.

Now, TOI has reported that ethical hackers have also deposited Re. 1 to Sharma's bank account, and have found Sharma's other bank accounts, IFSC codes, and even a particular payment history.

All this is reminiscent of Alderson's earlier warnings about Aadhaar.

It all started in March when Alderson, whose real name is Baptiste Robert, hacked into the Aadhaar app within a minute and reportedly gained access to 22,000 Aadhaar card details.

Despite Alderson's findings, UIDAI remained adamant about the robustness of Aadhaar's security.

Notably, this wasn't the first instance of Alderson hacking into government portals.

Initially, Alderson had found a loophole in the Aadhaar's Android application which revealed that users' biometric data was being saved in a local database by app developers whose password wasn't too difficult to obtain.

"These cards can be found on the internet. They are not on the UIDAI server. Everything is public, no hack is required," he said.

Alderson is a French security expert who is a network and telecommunications engineer by profession.

He claims to have no ulterior motive behind his revelations other than highlighting serious security vulnerabilities so that they can be patched at the earliest.

To be transparent about the whole process, Alderson openly communicates with the concerned organizations on Twitter, and often publicly posts DM conversations with them.

The French developer draws inspiration from renowned whistleblower Edward Snowden.

"By nature, I'm curious and I like to understand how things are working which often leads by finding security flaws," he said.

The 28-year-old cybersecurity expert does not have any sort of team behind him and follows a "standard process" to find security flaws.

On February 25, Alderson accessed the database of the Telangana government's benefit disbursement portal TSPost.

This contained personal information of 56 lakh beneficiaries of the National Rural Employment Guarantee scheme and 40 lakh beneficiaries of social security pensions.

He had also earlier highlighted that Paytm was seeking root access to users' devices, after which the mobile payments company removed the root request.

Previously, Alderson has discovered vulnerabilities in the online portals of Punjab Police, Indian Postal Service, Apollo Hospitals, and BSNL.

He says that even though it is "complicated," it is not entirely impossible to achieve almost 100% privacy online.

Interestingly, his username has been inspired by a character by the same name from the television series Mr. Robot, who is also a vigilante hacker.

Yet, for all of Alderson's alleged successes, it's important to note that the UIDAI's defense against Alderson's claims also holds some ground.

UIDAI points out that all the information pulled was available on the public domain owing to Sharma's long history of public service.

For instance, Sharma's mobile number was pulled from the NIC website, his email from the IIT-Delhi alumni portal, etc.
