A massive data breach exposing 16 billion login credentials has been confirmed, making it the largest ever recorded. Researchers discovered 30 datasets containing billions of records each, including logins from social media, VPNs, and major vendors. This newly uncovered data, mostly structured as URLs with logins and passwords, poses a significant risk for phishing attacks and account takeovers. Experts urge users to change passwords, use password managers, enable multi-factor authentication, and remain vigilant against credential theft.
