ADEX, the anti-fraud unit of AdTech Holding, reported on October 27, 2026 that artificial intelligence was involved in 52% of the ad-fraud schemes it flagged between January and September 2026. The rise of AI-generated landing pages, deepfakes and bot-chatters makes scams look more credible and harder to block. Marketers must act now to safeguard spend and brand reputation.
Why it matters now
The ADEX State of Ad Fraud 2026 report shows AI is now a core tool for fraudsters, powering fake news sites, counterfeit celebrity endorsements and round-the-clock scam chats. Because AI can mass-produce convincing assets, bad ads are rejected less often and re-appear quickly. The report also warns that in 2027 scammers will target AI assistants that browse and buy for consumers, expanding the attack surface beyond visual ads.
1. Audit creative assets for AI signatures
Check every new creative for tell-tale AI artifacts such as unnatural phrasing, generic stock images or deepfake-style facial distortions. ADEX found that cloned brands and fake endorsements appeared in 53% of AI-involved schemes, so a systematic review of brand-specific visuals and copy can catch many fraud attempts. Use detection tools that flag generated text or images before they go live.
2. Verify chatbot and landing-page authenticity
Bots impersonating humans were present in 64% of AI-driven schemes. Audit any automated chat or landing-page that claims to handle conversations round-the-clock. Ensure the bot is built on a verified platform, requires human oversight, and that its language patterns are reviewed for overly polished, generic responses. Flag any chatbot that can “handle conversations around the clock, responding fluently in the victim's language,” as described by ADEX.
3. Cross-check brand mentions and endorsements
AI-generated fake endorsements accounted for 53% of the AI-related fraud share. Scrutinize any influencer or celebrity quote attached to an ad. Verify the source through the influencer’s official channels or a brand-approval workflow. If an endorsement cannot be traced to a verified account, pause the campaign until proof is provided.
4. Monitor deepfake usage in video ads
Deepfakes appeared in 11% of AI-involved schemes, according to ADEX. Run video assets through forensic analysis tools that detect synthetic media. Look for mismatched lip sync, irregular lighting or unnatural eye movements. If a deepfake is suspected, replace the asset or request a genuine production.
5. Implement real-time traffic quality alerts
AI lowers the cost of generating invalid traffic that mimics human behavior. Set up alerts for sudden spikes in click-through rates, unusually low engagement time, or traffic from newly created IP ranges. ADEX’s data, drawn from eight ad platforms covering 1.2 million campaigns, shows that fraud can spread across many campaigns within a single scheme.
What this means for marketers
The surge in AI-driven fraud means marketers need tighter verification layers across creative, copy and traffic. Using ADFLU’s verified lead generation service can add an extra shield, as pre-qualified leads are screened for genuine intent, reducing exposure to AI-generated scams.

The bottom line
AI now powers more than half of ad-fraud schemes, making scams harder to spot and quicker to reappear. By auditing assets, verifying bots and endorsements, scanning videos for deepfakes, monitoring traffic anomalies, and training teams, marketers can cut the risk. Stay proactive, use detection tools, and partner with trusted verification services to keep ad spend safe.
