Routers can be compromised to install malicious firmware, as well as compromise user’s information.
D-Link has issued an advisory on their website (http://www.dlink.com.sg/securityadvisory/). They are aware of the issue and will be issuing a patch. Affected users are advised to refer to D-Link support page for updates and the appropriate firmware version for your model to apply when released.
Until a firmware update is available, users should take the following steps in the meantime to minimise the risk of your router being compromised.
- Disable remote management
- Use strong passwords for your WIFI to reduce the risk of unauthorised access to your network.
Users should also consider disabling the router’s SharePort feature.
Instructions on how to do so can be found in each router's manual at the following links:
