Reliance Jio database leak exposes dreary state of online privacy in India

Aadhaar-synced commercial databanks that telcos aim to build remain eminently vulnerable to cyber attacks.

This might very well be the biggest in the history of data breaches in India.

Reliance Jio customer data, comprising sensitive details of its 120 million users, including, as many have noted, their Aadhaar numbers, has been leaked online, and perhaps still remains in the black market of online data, where it’s sold to the highest bidder, and often leads to major cyber frauds.

A website named, which has been taken down at 11pm on July 9, posted the leaked Reliance Jio user identification data (or the Know Your Customer, KYC). The data remained online until reported it after being informed of Jio numbers throwing up customer details when entered in the search engine of the website.

The data that became available included personal details such as name, email id, circle, SIM activation date, and even Aadhaar numbers, according to

However, in its own counterchecking process, the online privacy website Medianama said that when it tried to see the results, Aadhaar numbers were redacted. However, it’s not clear if the Aadhaar redaction was specific to Medianama searches on, or if the website had altogether held back Aadhaar details, or had only selectively leaked the data synced to Reliance Jio SIMs.

Reliance Jio in denial

Of course, Reliance remains in deep denial about the matter of grave concern, as is evident in its nonchalant statement issued in the wake of the massive data breach. Casually brushing off the reports of the breach and the data obtained thereby as “unverified and unsubstantiated claims of the website”, Reliance Jio has nevertheless started a probe into the “contained” issue.

“We want to assure our subscribers that their data is safe and maintained with highest security. Data is only shared with authorities as per their requirement. We have informed law enforcement agencies about the claims of the website and will follow through to ensure strict action is taken,” a Jio spokesperson said according to the Indian Express.

What’s at stake here?

As reported by various tech and privacy websites, what’s at stake in the Jio data breach includes a number of things such as first name, second name, email, SIM activation date, circle, and even Aadhaar number in some cases. This is crucial because with this information, a SIM can be duplicated and misused. Emails can be hacked into and can be used for further cyberfrauds.

But the biggest concern here is the fact that Jio SIM in most cases is Aadhaar-synced and the availability of the biometric UID, which is supposed to be completely confidential and is meant for authentication for almost every service in the country, whether government and commercial. This means that the floodgates of further data breach and privacy violations of Jio users have been duly opened.

Even though Aadhaar can be locked once synced with one’s mobile number, this is a hardly known fact and isn’t the case with most synced mobile numbers. Moreover, Jio hasn’t answered questions posed to it by Medianama, such as how is the data stored, whether it’s encrypted and the level of encryption, if Aadhaar number is used to only authenticate or is also stored as part of Jio database, how the data could have leaked, what is Jio planning to curb such leaks in future, who all have access to the unencrypted database, and so on.

‘Data privacy is a joke in India’

Not just the editor of who himself became a victim of the latest breach in the data dyke of Reliance Jio, which, of course, is Aadhaar-synced, or activated via Aadhaar e-KYC, privacy activists in the country concur that “data privacy is a joke in India”. 

The latest breach of Reliance Jio data, which has not in fact been plugged, but only one highly suspicious website hosting the illegally obtained data has been rendered unavailable, is an indication of the abysmal state of online security, escalation of cyber frauds at a time when the government and big corporations, especially telcos like Reliance Jio, want to connect everything to Aadhaar, and make the biometric UID the central connecting node to the very digital existence of citizens in the country.


The Jio data breach, unlike the instances of Aadhaar data leaking from government websites in states like Jharkhand, is a classic case of data theft, to be sold and resold in whole or parts to bidders and data miners, the various corporations and online marketing companies for whom data is the new oil.

The website was registered just two months ago, to an individual who hasn’t disclosed his identity when domain name rights is searched.

Where does this leave Jio  users?

Despite an October 2015 Supreme Court order saying that telcos have no right to link Aadhaar with mobile numbers, it’s going unheeded like most SC orders on Aadhaar.

As the government goes on a rampage linking essential services like healthcare, PDS and ration, food supply for the poor, mid-day meals at government schools, enrollment in schools, hospitalisation, train ticket booking, and even bank accounts, to Aadhaar, the central question of the privacy activists is completely ignored.

The Aadhaar ecosystem, which has been thoroughly exposed as a leaky, fraud-prone extreme surveillance system that reduces citizens to transactional points and nothing more, suspending their fundamental rights to the will of an authoritarian regime, is a many-headed hydra.

Like Reliance Jio, which boasts of its fastest 100 million reach and tries to assure its users of ungodly data speeds, even though the reality is completely different, every other telco and commercial and governmental entities premised on Aadhaar, are vulnerable to cyber crimes.
