IdeaShared is one of numerous adware threats distributed under an easily identifiable “brand” – a round green app icon with an image of a magnifying glass inside. Its distribution is largely a matter of application bundles that conceal the infection and dump it onto a Mac under the guise of a harmless program installation. Once on board, it parasitizes the victim’s default browser by adding an extension called IdeaShared 1.0 that gets extensive permissions without actually requesting them in a straightforward way. This entity is to blame for injecting ads into web pages and reorganizing the traffic via browser redirects that lead to junk sites or search engines the user is unwilling to visit. It is also known to download other malicious items in a furtive fashion. While the activity of IdeaShared barely differs from that of dozens of its clones (including ForwardOpen, ForBrowser, MightyBrowser, DefaultProducts, CoordinatorPlus, PhaseSearch, and FocusProvide), it proved to be a more prolific and longstanding pest. First spotted in October 2019, this adware campaign is still up and running in 2020. If this PUA hits a Mac computer, it should be immediately removed so that the attack surface doesn’t expand through extra infections dropped onto the system surreptitiously.
