Does anyone know whether the rogue DNS server was successfully used to redirect any traffic to sites which may have intercepted /captured user data, banking details etc? For example I presume if the DNS had issued a fake IP for a bank it would be possible to create a proxy site for that bank that logs on to and presents data from the real bank.... but captures login details and the like for later exploit. Similarly it could be used to proxy and capture logins to Amazon, Paypal, eBay, Office 365, or anything else.... no doubt many other capabilities too. Keen to know if everyone who has used a network behind a hacked router should be recommended to change *everything*!

I've not personally gone in to try and see what's being redirected. I did run a few NSLOOKUPs yesterday to see if the IP was still active, and it is. But its not easy to pin-point what's being re-directed.

I think the key here is, just keep on-top of the new firmware as they come out and report any/all problems back to Draytek and hopefully post back to this forum?

Users would have seen a certificate warning in their browser if that is the case. Anything HTTP etc could have been compromised but generally all banks and reputable sites running on HTTPS would have shown certificate warnings if redirects were in place hence you'd hope users noticed..

Well, surely a fake site can also issue a fake certificate, or rather a real certificate which matches their IP address or even just redirect to a cleartext page. Most people probably don't actively look for the padlock...and also probably type www.lloyds.co.uk into their browser rather than https and get used to it redirecting to TLS.

Think Letsencrypt and/or Man-in-the-middle attacks. It's easy to see how things can be compromised.
