Online users have come to rely on social media and social networking sites to also update them on current events and commentaries, general news, and what's happening just down the street and around the corner.
This site serves ads on its default page and on individual posts. So every time someone shares one, the ads are shared with it. Below is a screenshot of a post:malvertisements, serving as a go-between for users and sites hosting malicious software.
For this particular Tumblr page, it uses the ad network Yllix Media. Google Safe Browsing profiled its official website here. Other third-party sites either blacklist the domain or flag it as untrustworthy due to its history of leading users to infected sites.
As of this writing, the ads are benign, but we may never know several months from now if this will still be the case.
Dear Reader, we encourage you to use ad blockers, such as AdBlock Plus (ABP) or NoScript (for Mozilla-based browsers only), if you don't want ads to appear on sites you visit. I personally use Ghostery. If you're not using one, please be wary of ads you click.
Malwarebytes Anti-Malware users are protected from malvertisements because of its Website Blocking feature. You can read more about this on "Oh, the Sites You Will Never See", an extensive post written by our Malware Intelligence Lead, Adam Kujawa.
