Is my iPhone being hacked, infected, or being controlled remotely?
Any feedback would be greatly appreciated.
First, I have an iPhone 4 that I have had for a couple of years now with operating system iOS 7.0.4. I have never jailbroken my phone. It is never in the possession of anyone else. No one else lives with me or uses my phone, except my girlfriend on occassion who has the exact same phone, but she has never experienced these problems I'm going to list here. On November 8th I started noticing that my phone was starting to act strangely.
First, it was starting to send text messages to people late at night (between 9PM and 4AM) in the morning. None of these text messages made sense. They randomly picked people from my contact list and sent group messages to people with stuff like "$-1", "(((7 vi", or it send links from web pages from somewhere like the Wall Street Journal. Some of the people included in the message weren't even people, just random gibberish that was typed in, like "vvyb-17@71". This only happened a couple nights as far as I can tell and hasn't happened since Nov 8th.
Second, my phone started browsing web pages randomly as well. It was going to my bookmarks or just random places in search engines. It would also put home button bookmarks of random pages on my home screen, usually just one a night if any at all. It does this every night.
Third, my phone starts flagging certain e-mails. It doesn't delete them, but it will flag them. It also drafts e-mails, but won't send them. It hasn't drafted any e-mails that were unsent since Nov 8th, but it will still flag them, randomly.
I have never plugged my phone into another computer other than the Mac mini I have at home. I have Wi-Fi turned on, but it is password protected with a firewall. There's no strange activity on my Mac mini that I can tell. My iPhone never used the iCloud before or when this started happening, so I don't think it's an iCloud issue. Currently I have an iCloud account because I needed one when I did a backup when doing the reformatting of my phone this Saturday when I called Apple support.
Saturday I called Apple support and I had my phone completely wiped off. There are no apps on the phone now and I changed all of my e-mail passwords as well as my Wi-Fi password. Last night, Sunday night, the strange activity started again with browsing random web pages on my phone and flagging e-mails. No texts were drafted or sent, but it's obvious to me that there are a few possibilities:
1.Somehow, someone or some thing is controllling my phone through the wireless connection at home. I don't know how this could happen, but it could be a weakness in my Wi-Fi/Internet setup at home
2.Apple's iOS has serious security issues that it is easy for someone to hack into and use my phone for goodness knows what.
3.My Mac Mini is infected and is controlling my phone through its internet connection. This seems ludicrous to me, but right now I will believe just about anything.
4.My Apple account is hacked and someone can control my phone that way?
Any help or suggestions would be appreciated.
Thanks
