Stupid question about browser redirect, but for peace of mind..
First, I know that these will seem like very naive questions, but I worry about this sort of thing, and am not particularly savvy.
Background: I recently had a browser redirect while using Safari on my iPhone. I won't give the full URLs here for obvious safety reasons, but I was redirected to "bidr DOT trillion DOT com" (which appears to be a "legitimate" company that directs web traffic to other sites for commercial purposes). From there to "wttracking DOT com," by which point I had managed to close things. I saw something about ads on "wttracking," before I shut it down.
I did some digging, which perhaps I shouldn't have done, because accidentally I managed to open "wttracking" again, which redirected to a secure site "wt2secure DOT com" (which is a login page). It says "WorldTrack" in whatever you call the additional information that comes after the URL in Google. I also at one point opened "worldtrack DOT com" by accident, which redirects to "wt1secure DOT com" All this was on my phone.
I suspect that all this is affiliated with the Worldtrack DOT co malware. "Wttracking" is registered by proxy (via Domains by Proxy), and I was unable to discover any legitimate company associated with all of this. As far as I can tell, nothing that I opened is detected as a threat by Virus Total (I don't believe that I ever opened Worldtrack DOT co itself.)
Naive question number 1: My understanding is that there are no known drive-by downloads that can affect Safari (or anything else) on an iPhone, as long as it's not jailbroken. So I shouldn't worry? This is basically for my peace of mind.
Naive question number 2: Would it be worth my while to reset my iPhone to its factory settings and restore it from a back-up on my computer?
Naive question (and this is the most naive one) number 3: If I did restore my iPhone from my computer, should I - for safety's sake - wipe it first before exposing my computer to it, or can I do the whole wipe and restore from within iTunes on the computer?
Also, if anyone has more information about "WorldTrack," I'd be interested to know if I'm right in my suspicions.
