Xfinity notifies its customers of data breach linked to software vulnerability

Hackers accessed Xfinity customers’ personal information by exploiting a vulnerability in software used by the company, the Comcast-owned telecommunications business announced this week.

In a Monday notice to customers, Xfinity said there was unauthorized access to internal systems as a result of this vulnerability — which was previously announced by software provider Citrix — between Oct. 16 and 19.

Xfinity discovered the “suspicious activity” on Oct. 25, and in the following months determined that information was “likely acquired.” On Dec. 6, the company concluded that information included usernames and hashed passwords — and, for some customers, the last four digits of Social Security numbers, account security questions, birthdates and contact information.
