Peruse this report on the aMuleC adware that proliferates through application bundling and spawns a slew of intrusive ads on visited web pages.
What is aMuleC?
The aMuleC adware reflects the nuts and bolts of unauthorized ad serving. Also referred to as aMule C, this malicious browser extension can get around user authorization while making changes to the regular preset of Chrome, Firefox and Internet Explorer. Essentially, it adds a virtual layer to a victim’s web surfing environment in order to inject sponsored data into sites being accessed from a contaminated computer. This potentially unwanted program is shareware that tends to accompany other apps as they are being installed.
The bundling-based distribution principle allows the offending code to sneak into PCs behind the scenes. An example of such a workflow is as follows: looking for a free multimedia player, video game or system optimizer, a user stumbles upon a dubious website that provides the required software, but the setup wizard actually promotes extra entities alongside the main product. By opting into the default installation mode, an unsuspecting user automatically agrees to also install the malign drive-by.
As soon as the aMuleC payload finds itself inside a machine, it adds a new plugin or extension to all web browsing clients detected on the system. The problem is that the victim is not presented with any authorization requests during this process. This makes the adware fundamentally different from normal browser extensions. Then, aMuleC abuses the wrongfully obtained high privileges to twist the way the infected web browser operates. It can interfere with DNS settings and Internet navigation preferences, including the homepage, new tab page and the default search engine. Furthermore, the adware gets unrestricted access to the user’s web surfing patterns, which may expose their lifestyle, habits and even such sensitive information as authentication details, including passwords for e-commerce and banking sites.
The most conspicuous impact of the aMuleC virus attack is the abundance of annoying advertisements being incorporated into pretty much every website. These ads tends to be deals, coupons, freebies, and price comparison charts. To top it off, the adware will be generating in-text links that expand as offer previews when the mouse cursor hovers over them. Yet another adverse effect revolves around interstitial ads that will be constantly popping up in the background. The victim may also experience browser hijack issues, where their web traffic gets redirected to various landing pages. Some of these unsafe sites may state that Java or Adobe Flash Player is out of date and recommend the user to install the latest version. The actual software distributed this way may be dangerous. File-encrypting ransomware infections and banking Trojans are known to spread through this sort of social engineering.
Unfortunately, the aMuleC virus is persistent enough to thwart easy removal. Infected users have reported error messages when trying to trash the associated browser extension. This is the scenario where some of the best adware removal practices step in.
