"OSX/Tored is different, however, because it is an email-aware worm which attempts to scoop up email addresses from your infected Mac computer and forward it to others. Its intended purpose, and presumed origin, is revealed in the opening comments of its RealBasic source code:
/ First Mac OS X Botnet
/Backdoor.OSX.Raedbot.C ,Reconnaissance worm/bot
/(c) Ag_Raed , Tunisia
Bugs in the worm's code, however, mean it is unlikely that you will ever encounter it, even if the author had taken the time to correct the many spelling mistakes in the emails it tries to send. So don't lose too much sleep."
