As an alert user of ABMaterial pointed out some malicious site is abusing a much used cache of the Google Analytics script. A lot of web developers used the cache on (do not click!) http://www.schedule-analytics.com/analytics.js, and up to ABMaterial 2.20, so did I as it was a lot faster than the default Google one.
Fix:
Make sure your script points to Googles secure site:
(function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){
(i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),
m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m)
})(window,document,'script','https://www.google-analytics.com/analytics.js','ga');
For users working with ABMaterial 2.20 or less, disable Google Analytics by commenting out the following lines:
' page.UseGoogleAnalytics("YourTrackingID", "")
In later versions (2.50+), this is not an issue, as it already points to Googles secure site.
I’ll release a new public version with the fix as soon as possible, but for now, just disable this feature.
