According to researchers from the cybersecurity firm Proof point, they recently discovered a large-scale malvertising campaign that exposed millions of internet users in the United States, Canada, the UK and Australia to malware infections. The malware campaign is being conducted by a hacking group called KovCoreg which is well known for distributing Kovter ad fraud malware. Recently KovCoreG hacking group initially took advantage of P0rnHub website to distribute fake browser to tricked internet users and steal their personal information for illegal use. The hacking group also tricked users into installing the Kovtar malware onto their systems so that they can continue to find out more useful information for the users.

I think this is a pretty interesting article but also very scary. I saw some analytical data on reddit at one point that p0rnhub has a crazy amount of hits in any given day. This being the case something like this could be a huge problem even if 1% of the people who go the site will go along with it.
