VexTrio’s Origin Story: From Spam to Scam to Adtech

Infoblox's investigative report profiles VexTrio — an international adtech criminal enterprise (including Los Pollos, TacoLoco, and Adtrafico) that operates a Traffic Distribution System (TDS) and smartlink ecosystem used to funnel visitors from compromised websites into scams (dating/crypto/tech-support), push-notification abuse, fake apps, and large-scale blank credit-card submission fraud; the paper documents dozens of affiliated companies, key personnel, hosting infrastructure, specific domains/services, and TTPs, and shows active, global-scale exploitation and ties to malware actors and website hackers.
