Yahoo Mail Worm/Virus?
I took a look at the full headers of the Spam emails and was able to track the originating IP address to Sunnyvale, CA (Yahoo's headquarters). I then compared this with old emails sent from both my home PC and my iPhone. Only the iPhone generated emails went through the Sunnyvale IPs. The emails sent from all three computers on my home network originated from local IPs.
So, bottom line... this leads me to believe that it was indeed my iPhone that somehow triggered the emails. I was driving at the time the emails were sent... so I know I didn't click anything, open any emails, or take any other actions that would have triggered the Spam.
Any idea what's going on here? Should I be concerned that my iPhone has a worm or virus that is triggering these messages? I'm particularly trying to determine if this is just a worm or if an actual person has hacked my account. I changed the password... but that password was also used for some other accounts of mine too. My biggest concern at this point is the potential for identity theft.
