Distribution of QSearch browser hijacker on Mac
QSearch is a nasty potentially undesired application – browser hijacker – which has been reported to be infecting Mac devices. At the moment security experts have not been able to identify a single tactic that is being used to infect the targets. We presume that the bad actors are using several of the most important methods to carry out malicious campaigns.
A common way of setting browser hijacker attacks like QSearch is the use of fake Flash Player update notifications. These nasty notifications are propagated on various questionable websites that in turn load in popular browsers as browser redirects. Other cases can utilize complex social engineering tricks and hyperlinks that are specifically made to confuse the intended targets into infecting themselves. Two more scenarios that are used in combination with email messages rely on infected files used as payloads ‒ documents and software installers.
- Infected Software Installers ‒ The criminals craft malicious packages made out of legitimate software installers. They are taken from the official vendor download sites, modified and then posted on online sites or attached (either as file attachments) or linked in the email messages.
- Infected Documents ‒ They represent dangerous files that usually come in the form of some of the most popular document types: rich text documents, spreadsheets and databases. When the users open them up a notification prompt will ask them to enable the built-in scripts (macros). If this is done then the malware is installed on the victim computer.
Malicious browser plugins carriers of QSearch and the associated program can be uploaded to hacker-controlled sites and P2P networks like BitTorrent as well. The hacker operators frequently utilize template design, text and images to create portals that look like legitimate download sources. They may also use domain names that are very similar to legitimate sites and advertise them via pop-ups or ad networks.
The browser hijacker code associated with QSearch may also be found in numerous malware toolbars. They are usually made for the most popular web browsers: Mozilla Firefox, Google Chrome, and Safari. They can be distributed on shady download sites or even on the browsers repositories (such as the Chrome Web Store for Google Chrome) using fake developer accounts.
Impact of QSearch Mac Virus
As we mentioned QSearch is a potentially undesired application of browser hijacker-type. However, QSearch is often considered as a virus by affected users. The good news is that the program is not developed to corrupt macOS and personal files. But it still poses a certain danger to victims’ online security and privacy.
Being classified as a potentially unwanted program, QSearch “virus” harasses online users by delivering numerous intrusive ads in their browsers. As a typical browser hijacker, the primary purpose of this program is to deliver as many ads to infected users as possible. This is due to the fact that the owners of QSearch get paid each time you click on an ad displayed by their nasty services.
The ads may appear during browsing sessions or even when your browser is closed. The intrusive ads can slow down the performance of the browser and the whole system as well. Crashes may happen sometimes. All pop-ups, pop-unders, images, banners and other types of ads injected by QSearch could display phrases like:
- Powered by QSearch
- Ads by QSearch
- Promoted by QSearch
- Displayed by QSearch
- Advertised by QSearch
Additionally, once QSearch establishes its malicious files on the system it is able to harvest specific details from your system and installed browsers. It is a common practice of undesired programs like the discussed one. This could be explained by the fact that malicious intenders attempt to build a complete profile of the victims with all their interests and patterns of online behavior. Then they could deliver targeted content or even sell the records to third-parties of unknown origin.
QSearch ads and all files associated with this infection expose your system at risk of severe malware attacks. Thus, they must be eliminated completely before any privacy and security risks occur. This is why we recommend that all infected users need to remove the active infections by following our in-depth removal guide.
