The records of 120 Million Reliance Jio customers were exposed online a few nights ago. A website Magicapk.com was being hosted by an unknown third-party which allowed for anyone to search through the information. Reliance denies that a breach occurred and says the information appears unauthentic. Writers at thehackernews.com claim that they were able to verify that some of the data being published was indeed authentic. At this point it is unknown how or when the breach occurred, but it appears to be the largest breach of personal information in India.
