# Comcast's Xfinity reports unauthorised access to its internal system.

**A recent security incident at** [**Xfinity**](https://www.mindstick.com/articles/126149/who-provide-the-best-xfinity-customer-service)**, affecting usernames, passwords, and potentially more, has sparked concerns among its customer base.** While the incident was patched quickly, sensitive information may have been accessed by unauthorized individuals. Here's a breakdown of the situation:

## Key Highlights:

- **Dates:** [Unauthorized access](https://www.mindstick.com/forum/158562/how-can-wireless-networks-be-secured-against-unauthorized-access-and-attacks) occurred between October 16th and 19th, 2023.

- **Action Taken:** Xfinity patched the vulnerability, alerted [law enforcement](https://answers.mindstick.com/qa/101683/how-is-internal-security-and-law-enforcement-managed-in-india), and is offering password resets and encouraging two-factor [authentication](https://www.mindstick.com/blog/177/authentication-and-authorization-in-asp-dot-net).

## Detailed Breakdown:

**Vulnerability Exploited:** The breach stemmed from a vulnerability in **Citrix software**, which Xfinity uses. Although patched, the vulnerability allowed access for a short period.

**Scope of Impact:** The full extent of the breach is still under investigation. While usernames and hashed passwords were accessed, the exposure of additional customer information may vary.

**Company Response:** Xfinity has notified federal law enforcement and continues data analysis. They are automatically prompting password changes and urging customers to adopt two-factor authentication.

**[Additional Information](https://www.mindstick.com/forum/160484/error-failed-to-launch-debug-adapter-additional-information-may-be-available-in-the-output-window):** Xfinity has not confirmed any [public data leaks](https://yourviews.mindstick.com/view/85544/beyond-locks-and-passcodes-the-cutting-edge-of-mobile-data-security) or targeted attacks against customers. The company's incident response team can be reached for further information and support.

**What to Do:** Remain vigilant, change your Xfinity password immediately, and consider enabling two-factor authentication for an extra layer of security. Keep yourself updated through official Xfinity channels.

**Remember:** While the risk of immediate harm appears low, [data breaches](https://www.mindstick.com/blog/303233/how-to-stop-the-applications-from-breaching-privacy) can have long-term consequences. Staying informed and taking proactive steps to safeguard your information is crucial.
