We’ve just intercepted yet another rogue ad campaign, attempting to trick users into installing the EzDownloaderpro PUA (Potentially Unwanted Application). Primarily relying on catchy “Play Now, Download Now” banners, the visual social engineering tactic of this campaign is similar to other PUA related campaigns we’ve previously profiled. Let’s take a look at this new rogue ad campaign, and provide relevant threat intelligence on the infrastructure behind it.
