We saw this news yesterday on the website of indiatimes, where they wrote that the 8.2 TB data of Mobikwik users has been hacked. Total 500 databases that includes 99 million = 10 Crores emails, phone numbers, passwords, addresses, gps location and more. Your credit card details might be also there as  40 million 10-digit card numbers,  3 million merchant KYC data which includes Aadhar card details, passport details, pan card details and photos that used for kyc.

Hacker who have allegedly the entire database of MobiKwik is selling it for 1.5 bitcoins on dark web, which amounts to around $85,000 or when convert to indian rupees it will be 62 Lakh Rupees. This news first out in public when French white hacker and security researcher Elliot Anderson posted in his twitter account with quote "Probably the largest KYC data leak in history. Congrats Mobikwik" see here

So now question comes in mind what is Risk?

• Your debit and Credit Card numbers with all details including CVV, expiry, etc now can be access, international transaction doesn't require OTP. So it might be Risky.

What Should You do now?

• Turn off International Transactions for now or block card. You might contact your bank
• Reduce the limit of domestic transactions

P.S: Mobikwik denying all with this comment.

"Some media-crazed so-called security researchers have repeatedly attempted to present concocted files wasting precious time of our organization as well as members of the media. We thoroughly investigated and did not find any security lapses. Our user and company data is completely safe and secure"
