For the last few days, we have had some customers come to us worried thinking that their websites were compromised with some type of pop-up malware. Every time they visited their own site they would get a strange pop up:
“Please stop hotlinking my easing script — use a real CDN instead. Many thanks”
What is going on?
We did some Google searches and found hundreds of threads with people worried about the same thing. Out of no where, that pop-up was showing up on their web sites. Were they all hacked?
