Not so much about Mac viruses specifically but some of you might find
this recent article about viruses in general, and the myths surrounding them an interesting read. Theres a little bit of Mac love in there.
We hear the same security by obscurity argument with LInux when it comes to viruses etc but Desktops asides, when you take into account all the webservers and embedded devices Linux runs upon it`s not quite that obscure after all.
Bad administration & social engineering are probably the biggest threats to Mac/Linux users(webservers included) and you only have to spend a little time on any Linux forums security board to see all the "i`ve been hacked" threads.....i cant really comment on Mac forums security boards of course.
