Dear Chet, Wim, and WeatherCat good netizens,
Thanks for your thoughtful summary Wim. You put the situation into clear focus. There is only one additional piece of information that might also put our mind at ease. At least some of the attacks where launched from emails with Trojan horse applications attached to them. According to reports, these Trojan horses would then scan the home network for devices to exploit. Such applications are clearly PC specific.
Mac users should definitely not rest on their laurels but a lot of ill is being done thanks to sloppy implementation of Microsoft and related software. Sadly, I fear that even Mac users are suffering an unjustified burden. Thanks the ease of exploiting windows applications and the associated maintenance headaches, people are fleeing personal computers in droves hoping to live safely in a world of mobile devices. Alas, such safety is most likely illusory. Nonetheless, in the meantime, I'm sure that former PC users are viewing Macs with an unreasonable suspicion of harboring the same ills as their PC analogues.
Cheers, Edouard
