In fact, I spent a few days last week dissecting an OS X port of the adware that shows attackers are going after Mac machines. This adware has been targeting Windows machines for a while but it is new to Macs: Antivirus software still can Not detect this adware so far.

Here are some components that I discovered in this adware:

–  “” does not use any exploits to compromise a Mac system. It infects machines by using a simple social engineering trick, deceiving people into providing their login details for a fake Flash Update or fake cracked software. This mechanism is generally known as bundling and ensures that “” successfully hijacks the normal installation process. With this hijack, users may think they are actually installing an adobe flash player while in reality an attack on the system is ongoing.

–  “” hijackers do not just exploit the vulnerability of the system; they use Apple Script to carry out their attack. The Apple Script tells users to open malicious advertisement pages automatically according to locations and cookies. This means the Apple Script was probably written by someone with a Linux background with only a little knowledge about OS X. in some computers, we also noticed “” launched an update process, making it possible to download adware such as “Advanced Mac Cleaner” from a remote system and deploy this “cleaner” to the Mac system.

There are two ways to remove this adware. The first is manual removal while the other is removal with the aid of Adware Removal Pro.

How to manually remove “” for Mac

“” always installs adware files with random names on your Mac so it is very difficult for Mac users to identify all infected files and ensure they are completely removed.

Step 1: remove malware

In the Finder, select

          Go ▹ Go to Folder…

Finder go-to-folder

Input ~/Library/LaunchAgents on popup dialog window and Press return.



then you would notice a folder named “LaunchDaemons” open. Check the names of each file in the “LaunchDaemons” folder. A normal plist file always has the format: “com.<company name>.<product name>.plist. Two perfect examples: and com.teamviewer.helper.plist.

However, the malicious file has this format: “com.<random characters>.plist. Two perfect examples: com.stagewise.plist and com.ZikcKtiR.plist.

It is possible you may not find potential malicious files in the LaunchDaemons folder. In this case, it would probably be that the adware has changed the naming rule. You can download the Adware Remover Pro – our free tool designed to clean adware automatically.

Go to the “Library/LaunchAgents” and“~/Library/LaunchAgents” folders, remove all malicious files following the same process as described in step one.
