At the Black Hat conference in August 2006, David Maynor and Jon “Johnny Cache” Ellch shocked the Mac community by demonstrating to the world something that hackers had known for a long time: the Mac could be hacked, easily. Maynor and Ellch, two security professionals with long-time careers in the security industry, were able to release what is known as a proof-of-concept attack by exploiting the wireless Atheros drivers built into the Mac operating system. Using a script called setup.sh, which turned a Mac computer (with its wireless card turned on) into an access point, an attacker could gain control of an unsuspecting Mac user’s laptop. Another hacker script, called bad_seed, could then be run from the host computer to exploit the vulnerability in the target computer’s wireless driver; this would give an attacker access to a Terminal session on the target computer running root (which is a “superuser” that is allowed full control of the computer). The exploit was not released, but it did provide proof that the Mac community was a long way away from an operating system immune to wireless attacks. While the Mac may be more resistant to attack, no system has every been truly immune.
