Infoblox and Confiant Detail Keitaro Abuse in AI-Driven Scams

Summary
Infoblox and Confiant’s four-month study identified about 15,500 domains used for malicious Keitaro instances, linking the tracker to AI-themed investment scams, tech-support fraud and phishing; vendor reports led to account and infrastructure takedowns.
Key points
- The researchers identified about 15,500 domains used for malicious Keitaro instances during the study period; about 9,000 were registered before use.
- Investment scams, especially AI-themed schemes using generated content and deepfakes, were the most common threat category observed.
- Operators use Keitaro’s conditional routing and fingerprinting—such as by location, user agent, ASN and referrer—to show lures to selected visitors and benign content to others.
- Campaign traffic came through compromised websites, spam, social media and advertising networks.
- FaiKast used AI-generated deepfake videos impersonating news figures to promote fraudulent investment schemes; researchers observed it entering the ad ecosystem primarily through Bigo Ads.
- FishSteaks campaigns used multi-stage giveaway pages to funnel visitors to phishing sites designed to collect personal and credit card information.
- The researchers say their abuse reports led to more than a dozen threat-actor accounts being canceled and infrastructure being removed; they also verified that TA2726 and other actors used illicit Keitaro copies.
