This is the second Safari security update in only 6 weeks. In the past, Apple has gone as long as 3 months without a Safari Security update. This may signal a greater attention to security issues by Apple.

There has been a long standing assumption that the Apple OS and Safari browser are safer the Windows platforms because hackers have focused on the larger target, with Windows operating 90% of all desktops. However, that may changes as Apple mobile devices with Safari proliferate and hackers become increasingly familiar with Apple platforms.
