Zombie Macs Launch DoS Attack

Cludge writes "ZDNet has a story (and several related articles) about how Symantec has discovered evidence of an all-Mac based botnet that is actively involved in a DOS attack. Apparently, security on the exploited Macs (call them iBots?) was compromised when unwary users bit-torrented pirated copies of iWork 09 and Photoshop CS4 that contained malware. From the article: 'They describe this as the "first real attempt to create a Mac botnet" and note that the zombie Macs are already being used for nefarious purposes.'"

    However, occasionally the rulers do tell someone. Under the usual su mechanism, once someone learns the root password who sympathizes with the ordinary users, he can tell the rest. The "wheel group" feature would make this impossible, and thus cement the power of the rulers.

When you have a user who is already scared to open any email at all from people he/she doesn't know, they're hopefully in good shape there. They're certainly not savvy enough to fire up bittorrent and start seeking out pirated software, either.)
