Timeline: Breach (2020-10-14) · Indexed (Mar 17, 2025) · Year (2020)

Executive Summary
In November 2020, ShinyHunters compromised the database of Indian online grocer BigBasket, and roughly 21.5 million customer records were sold on the dark web before being leaked for free in April 2021. Exposed data included names, email addresses, phone numbers, physical addresses, dates of birth, IP addresses, and passwords stored as Django (SHA-1) hashes.
ObscureIQ assessment: Exposure enables phishing, delivery fraud, account abuse, and household targeting. Purchase behavior can also support profiling of routines, family size, and dietary preferences.
Breach Impact
The combination of names, home addresses, phone numbers, and dates of birth supports identity fraud and physical-location profiling, with crackable SHA-1 credentials adding account-takeover risk.
