As Dr Bob gleefully points out, there is a virus for the Mac.
MacMerc is not impressed, calling it a script, albeit an evil one. And also one that has to ask authorisation from the administrator of the Mac to run itself. I'd like to see a PC virus that has the same courtesy.
And yes, I have already downloaded Norton's anti-virus definition to catch this little sucker. The first time I've had to run NAV for Mac in years. Unlike my PC, where my anti-virus (and anti-spyware etc) has to be run almost daily.
The new Opener virus (or "Malware") does pose a threat, but that's all it will ever pose. The script (as most educated users are calling it) disables OSX's built-in Firewall, creates a backdoor, downloads a password cracker, and ships your cracked passwords out to a home base (I'm sure it sends out more, but that's the most important item). However, like all scripts which modify system files, Opener must receive authorization from an administrator to run. Yes, this evil script will politely ask you for permission before ransacking your computer. The moral of the story is, don't give access to unknown processes and don't give your admin password to untrusted individuals.
In this case, the only security hole is the user.
