MyMacUpdater/Shopperify virus: remove fake MacUpdate from Mac

Learn how the MyMacUpdater and Shopperify ads viruses manifest themselves and remove them from Mac using a specially crafted security procedure.

Malvertising is shaping up to be an increasingly serious issue for Macs. A slew of PUAs (potentially unwanted applications) out there infiltrate computers and laptops stealthily and then wreak havoc with the way web pages are rendered to users. A really unsettling thing about this segment of the threat landscape is that the ne’er-do-wells in charge of such schemes are starting to employ growingly intricate tactics to reach their goals. For example, there is an ongoing large-scale malware campaign revolving around the app called MyMacUpdater, or MacUpdater. As it is running in the background on a targeted host beyond the victim’s sight, its main objective is to promote additional perpetrating code like the Shopperify adware.

‘Official’ website for Shopperify

MyMacUpdater virus proper is making the rounds via trojanized downloads. The infection chain typically involves a free application offered on uncertified software portals for Mac. The harmless-looking applet of the would-be prey’s choice can only be installed as part of a package, so it is a run-of-the-mill bundling hype. The contamination takes place on condition that the user accepts the default setup terms without exploring the custom option that allows deselecting unwanted items. Once inside, the offending code adds the com.MyMacUpdater.agent.plist entry to LaunchDaemons path under Library directory. This way, it gets enough privileges to manage system processes and trigger certain events behind the scenes.

MyMacUpdater promotes ad-serving malware that affects web pages

As it has been mentioned, the MyMacUpdater virus is aimed at downloading various types of malware onto a target Mac. In the past, it propped the distribution of the ad-serving infection known as OptiBuy. Currently, it is promoting an adware sample called Shopperify. When on board, it establishes obfuscated connection with a remote server and downloads said PUA without the victim’s authorization. An entry called com.Shopperify.agent.plist consequently ends up inside LaunchDaemons, just like the original infection.

The adware then focuses on tweaking the display of visited web pages. It generates what’s called a virtual layer that includes a variety of advertisements. These ads are presented on top of original site content. They include deals, comparison shopping boxes, special offers, coupons, freebies, banners, in-text and interstitial ads. The latter two types are particularly obnoxious – hyperlinked inline text is a piece of cake to click accidentally, and transitional ads assume the form of splash screens that may sit in the background and eat up the Mac’s resources. These items are usually labeled “Ads by Shopperify”, “Shopperify ads”, or “Brought by Shopperify”. Long story short, neither MyMacUpdater virus nor its protégé Shopperify adware belongs inside a Mac, so follow the steps below to get rid of both.
