BlackHole RAT is Latest Trojan Based Security Threat for Mac

"A new trojan-based security threat dubbed "BlackHole RAT" has hit the Mac, and while still in a rudimentary stage, still poses a real risk to Mac OS X users."

Something to be aware of really, since it is in the initial stages according to this report from iThreats. So what can you do to prevent this trojan from latching onto your system? Simple really, just avoid pirated software sites and only surf sites you trust, as this one requires user interaction in order to get installed on your system. I'm sure we will be hearing more about it as it progresses from it's current beta stage.
