Duh! A proxy, of course. Why didn't I think of that. I imagine that is what most hackers do to avoid being caught. Shows you how much I know about all this.

I really was baffled by all the different addresses, thinking it must be that many different individuals. I did look up more of the addresses, most of which also seemed to be from Korea.

Yes, I am paranoid. But not so paranoid as to believe that the Koreans are now trying to steal the original quilting patterns off my machine. (They wouldn't find much else of interest.) I didn't think it was likely that I was being singled out, but was sure curious why there should be such a flurry of activity on a given day. If it was all just a few individuals, though, it probably isn't all that out of the ordinary.
