Instagram Data Leak Exposes Sensitive Info of 17.5M Accounts

A reported breach has exposed roughly 17.5 million Instagram user records (usernames, emails, phone numbers and partial locations) which are being advertised on dark‑web marketplaces; security firm Malwarebytes links the listing to active exploitation, including password reset attempts and account hijacking. Users should enable two‑factor authentication, change passwords, monitor for suspicious messages and logins, and review connected apps, while Instagram/Meta have not yet issued an official response.
