Researchers at F-Secure have discovered a Mac OS X malware file masquerading as a PDF file to lure users into installing a backdoor trojan.

The malware, flagged as a trojan dropper, installs downloader component that downloads a backdoor program onto the system, while camouflaging its activity by opening a PDF file to distract the user.

As always with any OS, run an anti-virus and practice safe browsing habits. Hopefully this won't propagate any further.

I think it is funny how some people thing they are safe with a Mac on not getting a virus. I have always been told the only safe computer is one that never touches the internet. If any PC gets online it will be subject to virus activity at some point in time.

Yes I know there are more viruses for windows cause most people use Windows but as an OS gains more users than the hackers will adapt and start creating viruses for that OS.

I have always been told the only safe computer is one that never touches the internet.

Nor one that is exposed to removable media that has been used with the Internet.

The Internet is so big, so powerful and pointless that for some people it is a complete substitute for life.

I've found that even without the amount of viruses that Windows has OS X will still slow down and get bogged up so a clean install on a regular basis has been the norm for me. Always good to know that people are keeping a look out for us Mac users :)

Good one :hysterical: So if Windows and Mac are now vulnerable to viruses, looks like i will be using Linux now, hopefully that's virus free :P

No OS is guaranteed secure against malware. The first virus was written for the Apple II, actually.

Also, there is malware for Linux, but with a market share of about 1%...it's usually not worth the time to write malware for Linux (it's harder anyway).

Anyway, I'm sure quietman7 has some canned speech somewhere that would put my post to shame. :lol:

How a user sets up an operating system and uses it is much more indicative of whether it will get infected than what operating system it is.

http://www.bleepingcomputer.com/forums/topic257582.html

True, Linux by default is set up more securely, but that doesn't make it malware-proof. Rather similar to having a stout brick house, all doors with deadbolts, and a security alert system not being very secure if you invite the burglar into the house, give the security code to guests, leave doors or windows open, fail to lock the doors, or fail to set the security system.
