On December 20, Apple Computer released an upgrade to patch a serious security bug in the QuickTime multimedia application.

The application developer said this error could be exploited by hackers to turn QuickTime into a super-keyloglog to steal user information.

Hackers can embed a malicious Java Applet on the web and use it with the QuickTime for Java application to take a screenshot of the user's PC screen and send it to them.

QuickTime is turned into super-keylog images 1 If the above attack method is used in conjunction with Apple Quartz Composer, it will become an advanced screen capture method capable of capturing information on demand.

The above security error stems from a security error in QuickTime for Java. However, this security error only affects the QuickTime version for Mac OS X. The version for Windows does not make the mistake.

Users can go to the Apple website to download the latest patch.
