As VistaNews.ru reports, “The so-called payload VeryMal penetrates computers through ad image files saturated with steganography-based payload.” For readers who are unaware of the term, steganography means integrating text or data in an image. This works both ways as well. That is, users can extract data from an image too. Steganography is a pretty common process and doesn’t pose any harm as such. But, it can be exploited pretty easily. Mainly, that involves adding malicious code to the images.
Once the code is executed, it shows the users that an update of Flash is downloading. This might seem like a pretty dumb trick for most of us. But, macOS users are not well acquainted with the same. So they might easily fall prey to this trick. Moving on, installing the software would start a malvertising bot in the background. The bot clicks on ads to generate revenue for the people behind all this.
Avoiding the malware is pretty easy. Users need to pay attention to what stuff they are downloading on the internet. Moreover, ad blockers will definitely make it difficult for the malware to target the user. So, a good ad blocker might help as well.
