Hey Guys,

Anyone else recieve email from charter?

******************************************************
Dear Spectrum Internet Customer,

Charter Communications has been notified of a potential security related issue with your internet service.

Issue Description – A device on your network is capable of a network-impacting, distributed denial-of-service (DDoS) attack because it is acting as a DNS Open Resolver. This can allow hackers the ability to launch large attacks against others using your equipment.

We are asking that you take immediate action to remediate this issue.

Remediation Recommendations:

•Verify your router has the most current firmware.
•Consider disabling your DNS Proxy or Recursive Resolver in your router configuration settings.

Note: You may need to visit the webpage of your router’s manufacturer to obtain the latest firmware update or for information on how to make changes to your router.

@ crbartlett,

I am sorry for the inconvenience caused, you can disable the DNS proxy which would resolve the issue.

Open a browser and go to the web link and type (10.10.10.254\internet\lan.shtml), find the option DNS Proxy and hit disable. Our next firmware would take care of the issue. However, you can check the PM I am providing you a link for the firmware also, which can be uploaded via Web UI to resolve this.

Note: Tap on Status-->Web Admin for URL and user credentials.
