A number of users have reported in Google forums and Digital Point forums that their website is blocked by GSB and showing the following warning message "This web page at [site] has been reported as an attack page and has been blocked based on your security preferences."
Even after removing the MadAdsMedia script from their website, it is still showing the Malware warning.
"In my webmaster tools it lists the suspicious snippets as the links to madads. As I said before I removed them, then I tried to request a review in my webmaster tools but when I submit it I get: 'Your request can't be processed at this time because your site isn't currently flagged for malware. If you see a malware warning in your browser, it is likely a cross-site warning.' " One of the user posted in DigitalPoint forums.
It is still unknown whether Google mistakenly blocked those websites or the MadAdsWebsite is hacked to serve malicious ads. We are not sure how many number of websites have been affected.
According to fz6-forum, one of the MadAdsMedia advertising vendors' server was hacked and few ads have been injected with malicious code.
"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. " Mail from MadMAdsMedia reads.
