It has been reported that some web-enabled devices, including some DrayTek routers, have been compromised. The report shows that it may be possible for an attacker to intercept or create an administration session and change DNS and/or other settings on the router.
DrayTek has now released new firmware that addresses this security vulnerability. The firmware can be downloaded from: https://www.draytek.com/en/download/firmware/.
To check if your router has been compromised, look at the DNS and DHCP settings on your router. If you have a router supporting multiple LAN subnets, check the settings for each subnet. Your DNS settings should be either blank, set to the correct DNS server addresses from your ISP or DNS server addresses of a server which you have set (e.g. Google 220.127.116.11).
If you see a rogue DNS server setting of 18.104.22.168 – it means that your router settings have been changed. In this case you can correct the changes or restore the router configuration from the last good known backup configuration.
