The Search Marquis virus is a browser hijacker that has recently been reported to carry out infections against Mac users worldwide.

Usually, the hacker operators make it compatible with the most popular web browsers including the following: Safari, Google Chrome, Opera, and Mozilla Firefox.

Distribution of SearchMarquis Mac Virus
Search Marquis is a new nasty program for macOS which has been reported in various attacks worldwide. At the moment the security experts have not been able to identify a single tactic that is being used to infect the targets. We presume that the hackers are using several of the most important methods to carry out malicious campaigns.
A common way of setting browser hijacker attacks is the use of email spam messages. They may directly distribute malicious file attachments containing scripts that lead to an infection. 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.
The malware browser plugins 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 the Search Marquis can be found in numerous malware toolbars. They are usually made for the most popular web browsers: Mozilla Firefox, Google Chrome, Internet Explorer, Safari, Microsoft Edge. They can be distributed on such download sites or even on the browsers repositories (such as the Chrome Web Store for Google Chrome) using fake developer accounts.
Impact of Search Marquis
The Search Marquis hijacker on Mac is not malicious software. Hence, it is not a virus. But still, it lowers macOS security by helping hackers access the system. This threat on Mac like many others aims to alter some of the most important settings as regards web browsing. Parameters like default home page, search engine, and new tabs page may be all adjusted to load the deceptive search engine. Several security reports indicate that the infection is related to the so-called Bing redirect virus as well. So it is also possible that the hijacker will be redirecting affected browsers to the well-known Bing search engine.
Be very careful when searching through this search engine as it may be a hoax copycat of the original one. As a result, you may get tricked into visiting dangerous pages with malicious content. That’s why browser hijackers like SearchMarquis can be extremely dangerous. They covertly modify the installed web browsers and do not display a hacker-operated site as it is the most typical case. As a result, the only way that the victims can distinguish the infections is by looking at their address bar.
In addition to redirecting to hacker-controlled sites, they are responsible for other malware actions. The criminal operators can include code to perform in-depth information harvesting operations thereby retrieving a lot of information about the compromised host and user. When used as a part of a complex infection strategy it can also be used as means for additional malware redirect.
The malware components extract two main types of data:
- Personally-identifiable Data — Extracted data of this kind includes all manners of information that can identify the victims: real names, address, telephone numbers, social security number, accounts and passwords.
- Anonymous Metrics — This type of data is made up of metrics that are related to the browsing patterns but cannot be used to directly identify the users.
The malware site is used to constantly spy on the victim’s actions and relays this data to the hacker operators. The cookies are used to aggregate data about the site interactions, traffic, and preferences according to each user. All victims should note that the search results will probably contain sponsored sites or lead to further malware infections. Browser hijackers like this one are usually employed by criminals to redirect to pop-ups and similar threats. Furthermore, some of the links may lead to download portals that contain ransomware and other virus types.
Usually, the collected data is recorded in large databases that are shared between several sites and hijackers. The harvested records are then sold to marketing agencies or shared with partners that may abuse the data.
