    Summary

    In mid-October 2023, Comcast's Xfinity service suffered a massive data breach affecting nearly 36 million accounts due to an unpatched vulnerability in Citrix software. Hackers accessed sensitive information including usernames, partially obscured social security numbers, birth dates, and contact details. Despite discovering the vulnerability earlier, Xfinity only patched it after the data was compromised, leading to widespread concern and legal action.

    Severity

    The Comcast Xfinity data breach was highly severe, impacting nearly 36 million customers by exposing sensitive personal information such as birth dates and partial social security numbers. The breach was caused by a delayed response to a known security flaw, which allowed hackers easy access to the data. This has raised serious concerns about the company's security practices and led to multiple lawsuits, underlining the extensive potential for customer harm.
