Misuse of Cisco devices
CERT NZ is aware of an active issue targeting Cisco devices, such as routers, that have specific configurations enabled. The configuration, Smart Install, is not commonly used for routers in homes and is more commonly found in businesses where switches are used.
If you are a business, check if your router is a Cisco product. As far as we know, other brands are not affected.
What to do
It is not common for your home router to use the Smart Install configuration. If you are a business, you can check your Cisco router configurations or contact your IT support. They can read our technical advice.
