Hope someone will take responsablity for this breach. @RBI should investigate this issue. pic.twitter.com/LK8ZYddQfn— Rajshekhar Rajaharia (@rajaharia) February 26, 2021
Rajshekhar claimed that the actors behind the alleged breach claimed that they got access to the server in January 2021 and had access for over a month. He also claimed that the company removed a blog post about the 2010 data breach, but when we checked, it was still available.
What is in the leaked data?
As per the reports, the leaked data contains 36,099,759 files spread over 8.2 TB. It contains KYC details, addresses, email IDs, bank account numbers, credit card details, phone numbers and Aadhaar card numbers of MobiKwik customers. The data is up for sale for 1.5 Bitcoin, which converts to approx USD 85,000.
TechNadu said in a post that the email ids, phone numbers, passwords, apps installed, phone manufacturer, IP address, GPS locations, and other details of users were available in the file that is available on the darknet.
The actors behind the attack who go by the name ninja_storm, said in the sale post that they had recovered the data and it is up for sale. He further added in the post that the data could be used to secure small loans just like the USA but in India. “All data deleted on our end after the transfer,” said the hacker towards the end of the post.
Experts’ views on the breach
Troy Hunt, founder of Have I Been Pwned, a website that checks if someone’s email address or password was compromised, said in a tweet that companies should not behave as Mobikwik did in its March 4 post. “Try Googling ‘Mobikwik data breach’ now…,” he added.
Alon Gal, co-founder and CTO of Hudson Rock, called it a devastating hack. He said, “For each individual, there is just an astounding amount of information, this is really just a devastating hack, and all the data is up for sale by the threat actors.”

Vikash Chaudhary, CEO at HackersEra, said in a post on LinkedIn that his data is also available in the leak. He said, “India should have a strict data privacy law like the EU having GDPR. The saddest part is my data is also there.”
Kiran Jonnalagadda, the founder at HasGeek, said that the leak is real. In the thread posted by him on Twitter, he showed how one could determine if the hack is real. He said that the date in the dump matches an email that he had received by Mobikwik back in 2013 when he created an account on the app. Talking about the credit card details stored in the data dump, he alleged that he did not remember authorizing Mobikwik for saving the details.
The MobiKwik leak is real. Here is what the dump had for me. One of those credit cards was valid until a couple weeks ago, and I don’t recall authorising MobiKwik to save it. Companies that lie like 👇 ought to be taken to the cleaners. https://t.co/sptyC1Jz8f pic.twitter.com/c4Uu25OviP— Kiran Jonnalagadda (@jackerhack) March 29, 2021
While talking about the mismatch in password hash, he said the mismatch is creating some uncertainty. He added, “A password hash match would have made this irrefutable evidence as the password isn’t reused. Sans that, at this point, the evidence is merely compelling.”

Sunny Nehra, Admin at Hacks and Security, said, “The data is real. Anyone can check that by searching their own mobile no. they shared with Mobikwik. Refusal of hacks or leaks by companies have become common nowadays, and that’s costing a lot to their users. One should deny bogus claims, but real claims must be acknowledged.”

Mobikwik’s March 4 statement irked netizens
On March 4, Mobikwik had denied any data breach. In a tweet thread, they said, “We thoroughly investigated his allegations and did not find any security lapses. Our user and company data is completely safe and secure.”
The company further added that its legal team is looking into the matter. They said, “our legal team will be pursuing strict action against this so-called researcher who is trying to malign our brand reputation for ulterior motives.”
The month-old tweet thread has been making rounds on the social media platform, and Mobikwik users are not pleased with the denial.
Sanjeev Gupta, Secretary at ISCS, Ministry of Home Affairs, Government of India, said in a Tweet thread that after learning about the breach, he contacted some tech experts who informed him that his information was, in fact, available in the data dump. He shared a screenshot of the reply he got and said, “Mobikwik denied it on March 4. So, I tried URL sent to me on DM by some techies & also available publicly. Got all data including mobile no., email, #ed password, credit cards (fields for apps, CVV2, Expiry too!). I shudder to think for those who did full KVC using Aadhaar.”

He further added that his second mobile number was also in the dump. He urged users not to share all the information with payment solution companies, including Mobikwik, Paytm and Amazon.
My 2nd mobile no too proved #MobikwikDataLeak.While @MobiKwik issue is highlighted, beware all wallets including @paytm @amazon etc.Never save ur credit card details, manage with basic KYC & give less data. Don’t fall for full KYC offers & maintain separate low balance a/c for it pic.twitter.com/GK30egPhas— Sanjeev Gupta (@sanjg2k1) March 30, 2021
So out of the 3 CC details which were in the mobikwik app, the app shows only the one which is currently active. This means they are still storing data of old cards even though the app doesn’t show that to me. Wah Mobi ji Waah!— Karan Sachdev (@karansachdev) March 30, 2021
Yes this in India’s biggest KYC data leak ever and if you even signed up with Mobikwik then there is almost a confirmed chance that your data is leaked— Shubham Dutt (@shubhamdutt13) March 29, 2021

Sale of the dump suspended
According to a report published by The Hacker News, the sale of the data dump has been suspended by hackers. They said, “Only sell this to the company after due verification that we are dealing with company,” the hacker said in an update. By the update, it seems like the data dump is going to be used as means to extort money from Mobikwik.

Mobikwik was launched in August 2009 by Bipin Singh and Upasana Taku. Initially, it provided a mobile recharge facility. In 2012, Mobikwik launched an e-wallet system that allowed users to pay bills etc. Now, the company has extended its services to money transfer, loans and insurance as well. RBI authorized its semi-closed e-wallet in 2013. The company is planning to launch its IPO by September this year.
