A second worm has been spotted for Apple's OS X operating system.
Just like yesterday's specimen, the online pest is unlikely to cause much actual harm. In fact, F-Secure describes OSX/Inqtana.A as a proof of concept and notes that it will deactivate on 24 February 2006.
Leap-A may have beaten Inqtana.A in the race to become the first OS X worm, the new virus deserves credit for its increased level of sophistication. This one uses a (patched) vulnerability in the way the OS X handles Bluetooth communications, where yesterday's pest relied solely on social engineering.
The relative harmlessness of these worms seems to indicate that hackers have been engaged in a race to develop the first OS X worms for bragging rights rather than mischief. The theory is further supported by the timed release around the RSA Conference, the world's premier security event that wraps up today in San Jose.
