My girlfriend watched "some" pages on her iPhone and facebook.you-won.com
page appeared. She didn't know how to get rid of that JavaScript alert, so she clicked OK. After that she closed the page, and sent me the link with message "what is that".
I also clicked that link she sent. In Safari I found out, that it is some phishing page, so I closed it by restarting Safari on my iPhone and before the page loaded I quickly opened "panels" and left-swiped to close that page (all before the page loaded and that JavaScript alert appeared).
Because I think it's a phishing attack that is trying to steal your ID, I have 2 questions:
What can I do with HER iPhone (is restore enough to get rid of everything that could be downloaded? When she clicked OK?)
What can I do with MY iPhone? (I restored and recovered last backup from last week - this "page" appeared today, is it enough that I didn't click OK?).
I have my work "exchange" account on the iPhone, do I have to worry?
I have apps that are linked to my credit account (apps from my bank), do I have to worry?
I have credit card information saved in the App Store, do I have to worry?
She has nothing on her phone, just Facebook and some free games, so she is without problems I guess when I recover her iPhone.
Anyway none of those devices are jailbroken. Both iPhones have their original and newest iOS.
