It has already been termed as the largest KYC leak ever. Independent cyber security researchers have claimed that a database containing KYC details of nearly 3.5 million users of Indian payment app MobiKwik, in addition to personal and payments data of about 99,224,559 users, is up for sale on the Dark Web.
First tweeted by the independent cyber security researcher, Rajshekhar Rajaharia, and then confirmed by the French researcher Elliot Alderson, (who termed it the largest KYC leak (opens in new tab)), the alleged breach is pegged at 8.2TB data containing users’ phone numbers, emails, passwords, addresses, bank accounts and Aadhaar card details.
Mobikwik has denied the breach.
But a link from the dark web is available online, and several users on twitter have claimed seeing their personal details in it.
Some of them even posted screenshots of the alleged MobiKwik user data, which was reportedly up for sale for 1.5 bitcoin or about $86,000 (Rs 69 lakh) on a popular hacker forum.

"A media-crazed so-called security researcher has repeatedly over the last week presented concocted files wasting precious time of our organization while desperately trying to grab media attention. We thoroughly investigated his allegations and did not find any security lapses," MobiKwik tweeted (opens in new tab) from its official handle.

Seller says data can be used to raise loans
The denial does not square with the fact that the seller at the hacker forum has also calimed the the source to be MobiKwik. The samples of leaked data, in any case, contain images of MobiKwik QR codes.
As per a report in TechNadu (opens in new tab), "for the set price of 1.5 BTC ($84k), a buyer can get the entire database and have the dark web portal taken offline, keeping everything exclusive."
The seller of the data also claimed that the merchant entries can be used to raise loans by posing as the merchant.
"The seller claims that each of the merchant entries in the database can be used to raise $500-$1,000 loans in Indian currency, so the investment of the 1.5 BTC could supposedly yield up to three billion USD," the TechNadu report added.
