In 2006, a lot of debate centered around the exploitation of wireless networking drivers under Mac OS X. Although the original demonstration of this exploit was done using a third-party wireless card instead of Apple’s AirPort, this presented a major security concern. Apple has since updated its AirPort drivers to prevent similar attacks. However, third-party devices might still be at risk. Likewise, there are some risks because of driver fingerprinting in the 802.11 wireless standards that can affect all computing platforms, including Mac OS X.
There is also a vulnerability that was used to create the proof-of-concept Inqtana.A virus in Apple’s Bluetooth implementation. This vulnerability could allow a malicious user to load data onto a Mac’s hard drive without detection. Again, Apple has patched this vulnerability in one of its security updates.
