Ryan Naraine at ZDNet has a shocker: Symantec has said it has evidence of the first known Botnet comprised of Mac computers that are attempting to launch denial-of-service attacks. The root cause appears to be a cracked copies of iWork ’09 and Adobe Photoshop CS4 that also includes an additional payload with the Botnet code.
These applications are apparently making the rounds on BitTorrent. Moral of the story here? Stop using pirated apps.
OSX.Iservice and OSX.Iservice.B are the names of the files, which essentially obtain the password of the Mac machine allowing the hackers to take control. Estimates of affected Macs number in the thousands, Symantec estimates.
So much for the ‘Macs are immune’ meme. While this doesn’t point to an actual vulnerability just yet, it indicates that Macs like every other computer can be used for malicious purposes.
Of course the Apple faithful will be quick to yell this down, but I don’t think dismissing this is a good idea. So suck it up people and download a Mac virus scanner. Yes, you do need it.
I think the above is enough proof that the threat is real, no?
Update: Commenter Dave Barnes brought up another good program for detecting unwanted outgoing data: Little Snitch.
