Comparison of Adware in Windows and OS X: Linkular and Genieo

By definition, Adware is a program bundle which renders advertisements in order to generate revenue for its author. In a more strict sense, e.g. for security solutions, it means an application/installer whose nature lies somewhere between a potentially unwanted application and proper malware, like Trojans or Spyware. It might use more or less aggressive methods, starting with tricks and ending with fraud, to achieve its goals to benefit its distributor, while staying as innocent as possible on first sight. We blogged about an adware downloader a year ago.

Now we focus on two selected adware examples: The first is a Windows installer called Linkular and the second is a well-known application called Genieo (with a focus on its OS X version.) Being in the wild for a few months, the detection within AV products reached only partial coverage in both cases, with very similar numbers on VirusTotal (~10-20 %, see Sources below). However, the OS X adware Genieo is additionally flagged by OS X-specific security solutions. Considering maliciousness, the Windows adware is far more dangerous and invasive than the OS X one and also more than other Windows Adware examples we usually see. Here’s the comparison:

avast! Free Antivirus for Mac gets first place for malware detection

avast! Free Antivirus for Mac was pitted against 35 other antivirus products designed for Mac OS, including plenty of pricey solutions,  and came out in first place for detection of malware.free-mac

Compared to Windows, Mac users have been relatively free from malware attacks. But cybercrooks are just as aware as antivirus vendors of the behavior of users and their false sense of security and their habit of browsing the internet without security software. You only have to read this blog to learn that cybercrooks are adapting Windows malware for use on their Mac counterparts.

AVAST aces malware detection test

Over 300 malware samples and 35 applications were used to measure the effectiveness of products built specifically for Mac in a recent SecuritySpread.com test. Multiple machines running different operating systems were used to ensure the reliability of the test, and for real-world results, Macs that are used every day for a range of tasks from web development, media center, movie editing to gaming were included. avast! Free Antivirus for Mac had the highest detection rate among them all. The results can be found here.

The Security Spread test was done with avast! Free Antivirus for Mac 7, but in preparation for the official public release of Mac OS X 10.9, aka Mavericks, avast! Free Antivirus 8.0 has been released.  The changes are mostly under the hood, and it requires version 10.6.8 or newer. Download it here.

Notes on internal MacOS anti-malware tool (aka XProtect)

On August 28, 2009, Apple released Snow Leopard. One of new functions added to this version is basic anti-malware tool called “XProtect”. The name is based on the name of one .plist file which contains strings that are necessary for detection. Apple had not provided a name for the tool, so developers made it. Read more…
