I have recently been working in a few different countries, US, Australia, Hong Kong, Malaysia to name but a few.
In the meantime a friend of mine back in the States has been receiving some anonymous emails from a person who claimed to be in Germany. They're not spam - they're genuine emails, but they've been anonymous. They've either come from a Yahoo or Hotmail account. My friend has recently taken steps to get to the bottom of this and was surprised to see that on displaying the IP addresses of the anonymous mails, and searching out their location, they were actually sent from the exact same countries I've been in at the same time I've been there. Not only that but they contain very similar and in some cases IDENTICAL ip addresses to emails I sent her at similar times.
I now have an idea who this anonymous person is (someone who is known to both me and my friend). This person knows all three of the email addresses I use (a Yahoo, a Hotmail, and my work address), and all of these IP addresses have come up (even my work one) in the mails that have been sent to my friend.
Is it at all possible that this person could somehow continually hack into my email addresses and adopt my ip addresses as their own to avoid being caught out? How could they do that? I am now working in the UK and it is still happening. ie My friend just the other day received an email from both of us on the same day, with the same ip address. This other person still claims to be in Germany.
Any enlightenment would be gratefully received. Thanks.
