D
AT RISK
Xfinity's latest Wi-Fi 6E gateway. Same US company ownership and same public hotspot defaults as the XB7. The 2023 Comcast account breach is the most urgent issue to address.
- Public hotspot broadcasting - default on: Same as XB7: broadcasts a public xfinitywifi hotspot from your home hardware by default.
- Comcast 2023 breach - credentials at risk: If you haven't changed Xfinity credentials since late 2023, your account may still be compromised.
- ISP-controlled firmware: Comcast pushes firmware updates without your approval.
