What Is Pirrit Mac Virus?

Pirrit Mac Virus

 

In this article, you’ll learn all about Pirrit, a Mac adware program. Pirrit is a browser extension that works through the use of questionable ads, that can get your personal information stolen and send malware to your Mac. The dangers of Pirrit are often not realized until it has already infiltrated a system, resulting in many unnecessary financial consequences from wasted time on the computer to lost credit cards. Pirrit is a Mac adware that is designed to use advertisements for financial gain. Pirrit can be used to create revenue for the developer, by aggressively promoting affiliate websites and creating pop-up ads on websites of your choice. First detected in early 2018, Pirrit is still actively being distributed to the public, which is a bad sign. Pirrit was designed to work on the Mac platform, and has been known for a long time. Copyrighted code was found hidden within the adware program itself. How can this be allowed? This is another example of outdated and harmful software that should not be running on any device connected to the internet at any given time.

How Is Pirrit Mac Virus Distributed?

Pirrit Mac Virus is distributed through the use of “bundling”. Bundling is the act of adding additional software to your computer, when you install something else. While this practice was common in the early 2000s, it is now considered to be a harmful practice by many. Pirrit regularly uses bundling to infect Macs with spam bot programs and other malicious software, paid for by these pesky adware programs. The online advertisements and pop-up ads that appear on websites you are visiting, are designed to trick you into installing the Pirrit adware. This is done by showing a link that appears on a website, asking you to download an application to your Mac. When this happens, the software is usually bundled with another application that is downloaded onto your Mac. The bundle itself may call itself a browser optimization tool or something similar. Once installed, this bundle will install additional software and will start working in the background, which will then display unwanted ads.

How harmful is Pirrit Mac Virus? 

Pirrit is a Mac adware most commonly found on the internet with advertisements and pop-ups. Pirrit Mac adware is especially dangerous because it seeks to make significant money by promoting affiliate websites, advertised in popup ads across the web. You can end up paying for products you never even placed an order for. These affiliate sites are often advertising online pharmacy programs, which can contain potentially harmful infections or viruses. Pirrit also uses tracking cookies to monitor your physical location across the web, and to track your search history. Pirrit has been known to deliver pop-up ads, which can be very irritating. If you see a website with popup ads that are proving difficult to remove, then you could be hosting Pirrit software. Popup adverts often contain links that are disguised to look like legitimate updates that must be installed. These popup ads are malicious and will trick users into installing software onto their computers without their knowledge.

How did I get infected?

Pirrit Mac adware is most commonly associated with pop up ads. Ads that appear in a webpage that are difficult to remove, or ads that seem out of place on websites you visit. As Pirrit is placed directly onto these websites, however, it is likely that you have already been infected with Pirrit adware. There are many online locations where unwanted software can be downloaded and installed onto a Mac, for the purpose of earning money for the developer. If a website claims that it can help optimize your browser faster than ever before, or that a “free” browser extension is available, you might want to consider where the download is coming from. Pirrit has been known to bundle software and programs with other applications, which then automatically installs without the user’s knowledge. Pirrit adware also uses bundling for software downloads, so be sure to pay close attention to what you are downloading.
