This message is regarding the recent malware notifications that some of our publishers may have experienced. Just before noon today, our engineers discovered that one of our ad serving locations had been hacked.
Since this attack was discovered, our engineering team worked diligently until 3:45pm EST to ensure that the appropriate action was taken to secure our ad server. Unfortunately during that time, this attack effected 7.8% of our publishers’ domains. If you are one of these publishers, you can have Google remove the notification by following these steps: https://support.google.com/webmasters/answer/168328?hl=en
This warning typically takes only a few hours to be removed. We realize the seriousness of this matter and apologize for any inconvenience this may have caused our effected publishers. Our support team is available to answer any questions you may have.
Some of the websites that Grits maintains were attacked by malware from MadAdsMedia. But, thankfully, Sucuri was on top of it and discovered what the problem was, cleaned the sites, and requested that Google remove them from the Google Blacklist.
If you haven’t signed up for my monthly maintenance plans, you may want to do that just in case your site gets hacked.
