A website that reportedly contained the personal data of millions of Reliance Jio users surfaced on Sunday evening and crashed later that night presumably due under a high load of web traffic.

At roughly 6 pm on Sunday, a website called “magicapk.com” started making its way through various Indian social media channels including Twitter, WhatsApp and Reddit India. The website, which came with a simple user interface as shown above, simply asks visitors to enter a Reliance Jio mobile number to get access to “Jio sim details”.

Throughout the evening, the authenticity of some of the leaked data was confirmed by users online as well as tech website Fonearena.

It should be noted that the scale of this data breach is unclear at this point: when The Wire tried searching for a few Reliance Jio numbers, no results or personally identifiable information turned up.
