XProtect from Apple now fights Yontoo

After hearing much news of the new adware Web plug-in Trojan found to be affecting OS X systems, Apple releases an XProtect malware definitions update to protect anything that creates disturbance across it.Image

The Trojan, known as Yontoo, is initially disguised as a media player or download manager plug-in and distributed on underground file-sharing and movie trailer Web sites. When installed it pretends to be a player called Twit Tube but installs the Yontoo plug-in. This plug-in will work in all Web browsers to track your browsing behaviors and then present ads on legitimate Web sites.

Unlike other malware that can hide itself in a number of areas in the system, this malware is ultimately a basic Web plug-in that can easily be removed from the system’s plug-in directory. However, to help protect its users Apple has issued an update for its XProtect system so it will now identify the malware before it is installed.

XProtect  will check for malware in newly downloaded files as well as limit the use of out-of-date and potentially insecure Web plug-ins like Java and Flash.

In the latest definitions, Apple identifies the Yontoo malware as “OSX.AdPlugin.i,” so if anyone stumbles across it the system should issue a warning message that mentions this name.

In addition to the definitions for the Yontoo malware, Apple’s latest update changes the minimum Java version allowed to reflect the latest versions of the plug-in (version 1.7.17.06 and 1.6.0_43-b01-447), so some Java user must not get frustrated if they may experience a blocked plug-in message until they update, this is for your sytems safety.
