Is anyone else being redirected to a “congratulations you won” type website hosted on cloudfront.net? I’m using Safari, iPhone 6s, iOS 11.0.2, T Mobile, in NYC (only happens on LTE, doesn’t happen on wifi network)
I used to get those every so often. Since I've been massively firewalling sketchy domains, not so much.
(About 33k entries, mostly based on uBlock and other blocklists.)
I've discovered that Android does seem to have dnsmasq installed by default in explorations of my own non-jailbroken phone. Though I've not configured it.
Most of this I deal with at the router, using wifi.
AT&T in particular are exceptionally bad about this based on my exploration.
