“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 from its official handle.

Our user and company data is completely safe and secure. The various sample text files that he has been showcasing prove nothing. Anyone can create such text files to falsely harass any company, it added.

MobiKwik also said that its legal team will pursue action against the researcher.

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, “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.
