- Misleading Product Offers and Auto Redirects pose significant threats as the primary attack vectors following an assault by ScamClub leveraging malicious VAST tags.
- Google remains a top malicious SSP while nearly all major SSP infection rates rose in Q1.
From 2023- 2024, GeoEdge monitored and analyzed billions of advertising impressions across premium websites, apps, and SSPs to compile the research presented in this article. The data was collected using GeoEdge’s real-time ad security solution, which enables the measurement of quality and blocking of malvertising across devices and channels on live impressions.
Top Malvertising Attack Vectors Q1 2024
Misleading product offers and auto-redirects stand out as the most significant threats to the advertising ecosystem to date. Although auto-redirects show a decrease from the 2023 average, they still linger at a 25%, a significant share associated with the Scamclub VAST redirect campaign. Meanwhile, malicious extensions, add-ons, and financial scams persist as persistent threats. Q1 has also experienced a concerning rise in tech support scams, coinciding with a decline in gift card scams.

Malicious SSP Index
Malicious Ads vs All Ads Served
Google’s infection rate has slightly decreased from last year’s average of 1.25% but remains a top distributor of malicious ads, with 0.98% flagged as malicious. SSP06 has hit its worst performance yet, with almost 3% of its ads blocked for being malicious. SSP10, usually a high-quality SSP, saw its infection index peak at 0.86% this quarter—nearly three times higher than its 2023 score of 0.29%—due to financial scams and misleading offers targeting desktop users in the US and Canada.
Meanwhile, SSP12’s negative trend from Q4 continued into this quarter, with its malicious index climbing to an unprecedented 2.56%. This rise, primarily in January, was fueled by a significant number of financial and fake antivirus scam ads circulated by SSP12 in the US and Italy.
