Factinate noticed its bounce rates inexplicably rise, particularly on long-form blogs. Soon after, they saw alarming visitor comments on social media mentioning pop-ups and gift card redirects. It was at that point they knew their ad units were being hijacked.
Malvertising attacks occurred three days in one week, costing Factinate more than a hundred thousand dollars a year. The company’s two-man Ad Ops team was losing valuable hours manually tracking down threats article by article, page by page, only to have threats resurface after being caught and blocked.
