Welcome to our community and thanks for posting. Can we just clarify what emails you have been receiving? Can you tell us a little more about the issues you are having and we will try to help you as much as we can.
Please take action now: your home devices could be at risk
We have been alerted on four separate occasions a device connected to your home network has been identified as having a potential Portmapper vulnerability.
A Portmapper vulnerability is a security issue whereby a 3rd party can use this protocol to gain unauthorised access to your network/devices for malicious purposes. If a 3rd party has access to your network/devices they will be able to perform a Distributed Denial of Service (DDoS) attack.
It is therefore important that you follow the advice in this letter.
What has happened?
We suspect the device may have been misconfigured by you, someone in your household or without your knowledge. If the settings are left unchanged they can be exploited to unwittingly participate in malicious activities, for example a Distributed Denial ofService (DDoS) attack.
