Almost 60% Of Malicious Ads Come from Three Ad Providers
In the third quarter of 2019, Confiant saw the percentage of ads that are malicious fall from .25% to .15%, a new report by the firm indicates. While the study covered 75 supply side platforms (SSP), it found that just three of those are used to push over 60% of nefarious ads, with one of these SSPs even accounting for more than 30%.
The study also found that Sunday is by far the most common day for malicious ad campaigns to be launched, followed by Saturday and Monday. However, the biggest campaigns occur on holidays. The report identifies four main threat groups that are behind the bulk of malicious ads. These cybercrime operations are referred to as Scamclub, eGobbler, RunPMK, and Zirconium.
