One of the many things I found interesting was this quote:

“…spyware has become one of the biggest threats that businesses now face.”

Hmmm, I wonder how they are defining Spyware? I’ve seen malware, labeled as “Spyware”, that created a backdoor on a users system. I believe that malware is a more appropriate term, and agree that malware on the desktop poses the greatest threat to businesses.
They also list Zafi.D as being the most critical malware threat. It seems to fit the profile of typical malware that we have seen in the past: Spreads through email, adds itself to the system startup in the registry, masks itself as anti-virus software, kills all processes that contain the term “firewall” and “virus”, sets up a backdoor listener, and has the capabilty to update itself.
Whew, I used to say “Glad I run a Mac with OS X”, however Mac users are facing new and uglier threats than ever before (Of course, there is no mention of them in the report). I debated whether or not to post this link (there is no information targeted at “good guys” on this site), however I believe people should know:
This site contains shellcode, presentations, and exploits targeted specifically at OS X. This is only going to get worse with the switch to Intel, I’m told that shellcode (the bytecode injected into the system once exploited) is easier to write for Intel than for PowerPC. And with Apple potentially gaining more marketshare, they become more of a target.
