"Why Kaspersky won't say anything about Mac security now? Which version of Windows was hacked this time, in spite of one-week hole-filling updates?"
Wow... jumping the boat already. There could be many things that could have happened and yet you already jumped the guy trying to defend Mac when this have nothing to do with it. There could be many reasons why the code was obtained. Hell, their code repository could be on a Linux server and that was hacked. Or perhaps one of the programmers who runs a Mac or Windows and lost their computer which have their password and other information that's needed to get access to the code? Who knows they could even have lost their computers and that have all the code on it and the news spin it as "VMWare was hacked!"
