Massive Data Breach: Millions of Xfinity Customers' Information Compromised

Millions of Xfinity customers' personal data, including usernames, hashed passwords, contact details, and secret security question-answers, may have been stolen in a cyberattack exploiting the Citrix Bleed vulnerability. Comcast, the internet, voice, and cable TV provider, discovered unauthorized access to its internal systems between October 16 and October 19, affecting an estimated 35.9 million people. The potentially stolen customer data includes usernames, hashed passwords, names, contact information, the last four digits of Social Security numbers, dates of birth, and secret questions and answers. Xfinity is urging customers to reset their passwords and enable two- or multi-factor authentication.
