An alleged database of about 20 million BigBasket users has leaked on a well-known cybercrime forum, months after the Indian grocery delivery startup confirmed it had faced a data breach.

The database includes usersโ€™ email address, phone number, address, scrambled password, date of birth, and scores of interactions they had with the service. TechCrunch confirmed details of some customers listed in the database โ€” including those of the author.

BigBasket co-founders did not respond to texts requesting comment.

The startup confirmed in November last year that it had suffered a data breach after reports emerged that hackers had siphoned off information of 20 million customers from the platform.

TechCrunch has asked one BigBasket co-founder whether the startup ever disclosed the data breach to customers.

A hacker who goes by the name ShinyHunters published the alleged BigBasket database โ€” and made it available for anyone to download โ€” on a popular cybercrime forum over the weekend. In newer posts on the forum, several threat actors claimed that they had decoded the hashed passwords and were selling it. ShinyHunters didnโ€™t immediately respond to a text requesting comment.

The incident comes weeks after Indian conglomerate Tata Group agreed to acquire BigBasket, valuing the Indian startup at over $1.8 billion. The acquisition proposal is currently awaiting approval by the Indian regulator.
