Pirrit Adware – How Did I Get It

The primary method by which this virus spreads according to researchers is reported to likely be via an online marketing company’s website, known as TargetingEdge, which may be based in Israel. In addition to this, another likely method of replication of OSX.Pirrit is likely via software bundling that disguises this unwanted program as something that is of a helpful nature and is added as a free extra to a free program the user is trying to install. Such free programs are your average video converter app or an app that helps you download free media content. Usually these free apps are available on third-party sites, where Pirrit may also be offered as an addition in their installers or even may be automatically added alongside them.

There is no specific information about the TargetingEdge company, but it is clear that It is related to several other companies as it’s website suggests:

TargetingEdge is related to two other companies, TLV Media, which makes an ad targeting and ad monetization platform, and Feature Forward, which sells a video platform. According to LinkedIn, all three companies have the same board of directors and the executive who created the OSX.Pirrit variant previously worked for TLV Media.

Furthermore, in a research on Pirrit, done by Amit Serper, a security analyst at Cybereason, the company was also reported to likely be associated with such activity for quite some time. And not only this but the Pirrit adware has similar activity to malware infections.

Attackers could have used the capabilities built into OSX.Pirrit to install a keylogger and steal your log-in credentials or make off with your company’s intellectual property, among many other bad outcomes.

Furthrmore, the malware has also been reported to be far more dangerous than it’s traditional Windows variant In the sense that it has a lot of capabilities added to it’s Mac version and some of them have nothing to do with adware, because they may be able to obtain the following information from your Mac:

  • Taking screenshots.
  • Obtaining saved passwords on your web browser.
