Mobile gadgets are less susceptible to malware attacks than desktop computers, but they are shaping up to make an environment increasingly targeted by threat actors. No wonder – the user base and attack surface are potentially huge, which is a lure that crooks couldn’t possibly ignore. The app called Leadbolt is an Android adware sample that exemplifies this rising trend.

What is Leadbolt?

Leadbolt is a mobile advertising platforms built to facilitate ad delivery. The main officially declared goal of said solution is to get merchants and advertising entities together on the product promotion job. There is technically nothing wrong about such a mission – in fact, the service is one of many. However, numerous users have been leaving unfavorable feedback regarding Ads by Leadbolt that tend to get very annoying. These unwelcome objects pop up all of a sudden, sometimes occupying the entire screen of an infected Android device. To top it off, intrusive adverts may be embedded in web pages the victim surfs to. Not only do these items irritate target users, but they also affect the performance of a contaminated smartphone or tablet and may become a privacy concern.

Leadbolt and related apps

Ads powered by Leadbolt typically make an appearance on a device after the user installs some free app from resources other than the official Google Play store. The architects of these malvertising campaigns usually employ application bundling to distribute affiliated products. The scheme is as follows: you find a freeware solution, such as a video makers or file downloader, and install it thinking it’s a great match for your current needs. The trick is that these apps are installed alongside third-party programs. Some of the accompanying utilities may end up causing trouble, as is the case with Leadbolt and its associates. At the end of the day, the potentially unwanted program slips inside without clear authorization, which is definitely not the way a regular applet will propagate.

It usually creates several icons on the home screen, linking to an affiliated search provider and something like an app downloader. The list of linked-to services may vary, though.
