I'm bored of reading this crap and amazed at how much attention it has gotten - not so amazed and how uninformed most of the articles are though. 🙄
Lets get this straight from the beginning: the malware that is 'opener' is not a virus, it is not a worm, it is not even a trojan (unless it's comes piggybacked on some other application). It is a rootkit.
The threat of rootkits on OSX is real, no doubt about it, comes part and parcel of being part of *nix world. But it takes effort on your part to install it - very different to what it is like being on a Windows computer!
But 'opener' is not the threat that people are making it out to be/wishing it was. It has no known means of transport or any other way to infect computers that anyone has seen to date and its full source has been verified. As it stands in the virus world this type of thing is rated about as non-threatening as you can get.
This thing is just a glorified shell script, and is not even a pre-compiled binary. Meaning that it tells you what it is doing if you know bash. This thing is about scary as me writing a script in AppleScript and asking you to run it, and send it out to your friends as well whilst you're at it please. 🙄
This amatuerish piece of malware is generating a lot of headlines and ill-informed articles for very little reason. The only thing to be had from this whole fiasco is seeing how much people want Mac's to fall flat on their faces for daring to have a more secure system than Windows! 😱 😉 😛
