Among the security threats Mac users should be concerned about, browser hackers such as SearchMarquis.com stand out because of their aggressive nature.

What is the Marquis Mac virus?
If you think that Mac malware is a peripheral phenomenon, the malignant SearchMarquis.com will prove you wrong. In fact, malicious programs targeting devices running the undeniably amazing MacOS operating system have been around for some time and have become widespread in recent years. The above tension is an excellent example of the repeated campaigns of cyber criminals in this category. Its negative effects generally extend to interference with navigators, but the supposedly limited area of attack is a mock comfort. Victims are faced with very annoying redirections to SearchMarquis.com, which for seemingly inexplicable reasons works in their standard browser. However, there is a clear reason. Behind each of these difficulties lies malicious software. The goal is to intercept Internet traffic from Mac users and redirect it to another service via the ad network. This trick allows the crooks to monetize the attack with all their might.
What is the target group of this campaign? The answer may seem surprising to some – it’s Bing, a search engine from Microsoft. The vagaries and antlers of such a strange trick are in the nature of the kidnapping. As mentioned before, the path of the twisted navigation in this scenario is more complex than it seems. Technically, the victim leaves SearchMarquis.com and then enters several subdomains, including the infamous SearchBaron.com, before entering Bing.com. These visits are almost invisible and are only directly visible in the status bar at the bottom of the browser window. So Bing is just a camouflage that should give an electronic raid a touch of legitimacy. For thieves, a number of intermediate addresses, which are permitted along the way, are important. The latest adaptation of the Search Marquis interception wave has introduced a number of additional areas into the mix. It took root in the summer of 2020. In addition to targeting Bing, malware operators have started using mybrowser-search.com. As you can see in the screenshot below, this service uses Google’s Custom Search API instead of returning your own results.
The crime of the virus on SearchMarquis.com is a secret meeting. The payload is usually hindered by an installation client, which seems to facilitate the implementation of a flawless application. An elegant program – usually free of charge – is just the tip of the iceberg that distracts Mac users from tips. It turns out that the package contains standard extra items, including the Search Marquis basket. In this situation, troubleshooting is not easy – just select a custom installation, which should display the full list of sponsored applications and allow the user to disable unnecessary applications. However, it is unlikely that there will ever be any caution in this regard, which means that people will just press the button and stop the process to understand that some wonderful free program has bought the company.
When the virus is launched, it rearranges the system configuration so that the victim’s default web browser – Safari, Google Chrome or Mozilla Firefox – SearchMarquis.com returns each time the victim tries to open their homepage or favorite search engine. The trick to change the parameters is not complicated in itself, but a kind of persistent implementation is an obstacle to repair. In other words, returning manually to the correct settings for surfing the web does not help, because the virus reapplies unnecessary settings.
This is largely due to the creation of a questionable configuration profile on an infected Mac as part of the attack. With this trick, the malware monitors the behavior of the browser and returns unwanted settings after the victim has tried to return to normal settings. In Google Chrome, for example, this technique leads to a new company policy that is difficult to circumvent. One of the main symptoms of this intervention is the Managed by your organization label in the browser configuration drop-down menu. After this attack, the affected browser is asked to disable and enable SearchMarquis.com, which in turn redirects all searches to Bing if multiple additional domains are affected. Clearly, nobody cares about this crap. This is what you can do to block the annoying browser redirection.
