Today we got a sample of rather interesting case, a Mac OS X Bluetooth worm that spreads over Bluetooth.
If you are using OS X 10.4 make sure that you have latest security patches installed and you are safe from Inqtana.A and any future worm that tries to use same exploit.
Inqtana.A has not been met in the wild and it uses Bluetooth library that is locked into specific Bluetooth address and the library expires on 24. February 2006. So it is quite unlikely that Inqtana.A would be any kind of threat.
