The Evolution of Vextrio: A Deep Dive into Digital Fraud

This week, we are joined by Dr. Renée Burton, VP of Infoblox Threat Intel, who is discussing their work on VexTrio, a notorious traffic distribution system (TDS) involved in digital fraud. The VexTrio investigation uncovers a massive global ad fraud and scam operation powered by just 250 virtual machines, tying it directly to named individuals and shell companies across Europe.

The research exposes VexTrio’s full criminal supply chain—including fake apps, dating scams, affiliate networks, and payment processors—alongside a powerful CDN infrastructure ranked among the world’s top 10k domains. It also calls on the adtech industry to take accountability for enabling and sustaining such widespread abuse.

Complete our annual ⁠⁠⁠⁠audience survey⁠⁠⁠⁠ before August 31.
