Given recent activity, McAfee AVERT Labs forecasts that attackers may attempt to test the viability of exploiting this vulnerability en masse, by producing a reconnaissance Trojan to identify a vulnerable user base. Exploit source code with a payload has been published. Now, the message is 'welcome to zero-day vulnerability land for many Mac OS X users' Only, Mac OS X users are less prepared, less aware and mitigation tools are less evolved.
