Faith is not enough for this one
Apple is telling Mac users with Java installed should act quickly to install the latest version of Java from Apple. A security flaw is already being exploited by the Flashback Trojan in drive-by download attacks and turning Jobs' Mob's expensive shiny toys to jelly.
Most Apple security is based on the idea that by praying to the Apple logo on your machine, all viruses and malware will bounce off the hardware and be sent to a Microsoft machine. But there was some fear that this particular prayer was not working on a nasty variant of the Flashback Trojan.
Apple updated Java to version 6 update 31 for OS X 10.6 (Snow Leopard) and 10.7 (Lion) on Apr. 3. The update addressed 12 vulnerabilities in Java, which could be exploited by malicious Websites to run code using the privileges of the current user.
However one wonders why Apple did not do this sooner Oracle fixed the same security flaw for Java for Windows, Linux, and Unix back in February. It seems that Apple wanted to make sure that the prayer was given a chance to work.
