Right. And Worms which infect peoples systems via Microsoft Outlook Emails (or XYZ cross platform app emails in Windows) arent a Windows issue too eh? They use another app to infect your system (or that app) when you use it. Lets say said cracker decides to use Thunderbird next time to send you an infected file (such as the one from that article), and said infected file when opened, infects your system. Does that then mean that its not a Linux issue?.. Who gives a f*ck what its called after your system becomes infected or affected by this? Either way, your now someones spam bot b*tch, Linux user or not, because you opened that infected file using Thunderbird, or whatever XYZ cross platform email app. The point is not wether its a Linux worm or a Windows worm. Its about wether that worm can affect people using Linux, and it can as the above cracker quite expertly proved, and will most likely prove again, and again, and again, and again.
