Massive Data Breach: Xfinity Hack Exposes Millions of Customer Records

Hackers exploited a critical security vulnerability known as "CitrixBleed" to gain access to the sensitive information of nearly 36 million Xfinity customers. The vulnerability, found in Citrix networking devices, has been under mass-exploitation since August. Xfinity confirmed that hackers had access to its internal systems between October 16 and 19, but the malicious activity was not detected until October 25. Customer data, including usernames, hashed passwords, names, contact information, dates of birth, and partial Social Security numbers, may have been accessed. Comcast has not disclosed the exact number of affected customers but confirmed that almost 35.8 million customers are impacted. The company is requiring customers to reset their passwords and recommends the use of two-factor authentication.
