It is being reported that BigBasket’s recent data leak has exposed the data of some Flipkart users as well.

E-commerce platforms Flipkart and BigBasket were recently embroiled in a data leak. It is being reported that BigBasket’s recent data leak has exposed the data of some Flipkart users as well. The matter has resurfaced seven months after it was first discovered. BigBasket was involved in a massive data breach in November which had comprised personal data of around 2 crore users. Many months later the data was put on sale online. Following the leak, some users who had the same credentials for Flipkart and BigBasket have complained that their accounts are being hacked. This is only happening to Flipkart users as of now. One of the users named Satish Medapati posted on Twitter that his Flipkart account details including his name, password were changed. He also told Inc42 that he had received OTPs for orders that he had not placed. “About 17 orders were placed. Reward coins were used and there were attempts to buy through my saved credit cards on Flipkart. About 30+ OTPs on various issues came from Flipkart,” he told the publication.
