I have just had a mysterious thing happen: a calendar event has appeared out of nowhere.
At more or less the same time I received a similar email:
Now I am used to email spam, but how on earth has this calendar event infiltrated my machine?
I haven't opened any email attachment. Mail can't have opened an email attachment on my behalf, as that above email is the only email I've received today; it contains a single image attachment (not particularly exciting). I think this must be a red herring, as I had to specifically instruct Mail to display the image, and I only did this after receiving the calendar event.
And this calendar event appeared completely of its own volition. I was just staring at some document I have open in Preview.
Is my machine compromised? Does it have some door open that should be closed?
I have never before had any anomalous occurrence in seven years of using Apple machines. What is going on here?
PS Also I have never used the calendar application. I did purchase this machine second-hand about three months ago, so maybe something is left over from the previous user, but the machine came to me with a seemingly fresh OS X installation, so it seems unlikely.
