There is a new hole that was discovered recently about the password encryption on the BT Home Hub which is the most popular Wi-Fi Router in Britain.
According to an article at Channel Register, the security department of BT changed the default password from “admin” to the router’s serial number. However, requests to the device’s multicast IP address are answered so their passwords are exposed. The article also notes that these cases only applies to requests that was sent by machine to the local area network.
The article includes a link on how users can lock down their connection to keep them safe.
