Last night I told you that, for the first time, Apple confirmed that some computers of its own employees were exploited by some hackers and that a software update is to be released to protect users. It seems that Java is again to blame for these problems, software vulnerabilities allowing hackers to compromise some Macs of Apple employees. Those from Cupertino launched during this night an update for the Java software, it has the role of closing the vulnerabilities and it is advisable to install it, if you have not already done so.
Java for OS X 2013-001 delivers improved security, reliability, and compatibility by updating Java SE 6 to 1.6.0_41. On systems that have not already installed Java for OS X 2012-006, this update disables the Java SE 6 applet plug-in. To use applets on a web page, click on the region labeled "Missing plug-in" to download the latest version of the Java applet plug-in from Oracle. Please quit any web browsers and Java applications before installing this update.
The update can be installed through the Software Update system available in OS X.
UPDATED: Behind the hacker attack may be WEBSITE iPhoneDevSDK which appears to have been used to host malware designed by hackers. Apple employees would have accessed that website and through a Java plugin would have infected their Macs, but for now the information is not confirmed by Apple or those from Facebook.
