How AI-Native Development Platforms Enable Fake Captcha Pages
Summary:
Trend Micro has reported a notable rise in phishing campaigns that exploit AI-powered platforms such as Lovable, Netlify, and Vercel to host fake CAPTCHA challenge pages. These attacks have been tracked since January and represent a significant evolution in phishing tactics. The setup is deceptively simple: victims receive a phishing email with urgent messages like “Password Reset Required” or “USPS Change of Address Notification.” When they click the embedded link, they are directed to what appears to be a harmless CAPTCHA page. By requiring users to solve the CAPTCHA before continuing, attackers lower suspicion and create a sense of legitimacy. Once the CAPTCHA is solved, victims are redirected to a phishing site where credentials and sensitive data can be harvested.
This method not only tricks users but also successfully bypasses many automated security tools. Scanners typically analyze only the initial CAPTCHA page, which appears legitimate, and fail to follow through to the hidden credential-harvesting site. This dual advantage—misleading users while evading detection, makes the tactic particularly effective. Attackers are further aided by the characteristics of these AI-driven platforms. Lovable, Netlify, and Vercel are designed to simplify website creation with minimal coding skills, making them attractive not just to developers but also to cybercriminals. Free hosting tiers significantly reduce the cost of launching campaigns, and the use of trusted domains such as *.vercel.app and *.netlify.app lends credibility that victims may not question
Security Officer Comments:
Trend Micro’s analysis highlights the scale of this abuse: 52 malicious sites were found hosted on Vercel, 43 on Lovable, and 3 on Netlify. While Lovable is often linked to quick AI-assisted site creation, Vercel has emerged as a hotspot for phishing campaigns, likely due to its wider adoption and familiarity among attackers. Campaign activity peaked between February and April, before dipping slightly, and then spiked again in August, demonstrating persistence and adaptability among threat actors. The success of fake CAPTCHA phishing lies in its ability to manipulate both human psychology and technological blind spots. Users assume CAPTCHAs are a routine step to verify legitimacy, making them less likely to question the page. Meanwhile, automated defenses struggle to detect the malicious redirection hidden behind the CAPTCHA challenge. This combination makes the tactic highly effective for attackers seeking scale and stealth.

Suggested Corrections:
- Educate employees on how to spot captcha-based phishing attempts. This includes educating them to verify URLs before interacting with captchas, use password managers (which won’t autofill on phishing sites), and report suspicious pages.
- Implement defenses capable of analyzing redirect chains. For example, organizations can deploy security tools that can evaluate outbound connections and block access to domains known for abuse, even if they look legitimate at first.
- Monitor trusted domains for signs of abuse by tracking traffic to their subdomains, correlating logs with threat intelligence feeds, setting automated alerts or blocks for suspicious activity, and reporting malicious instances to the providers for takedowns.
- Set up an email security solution with scanning capabilities to detect and proactively block emails containing suspicious content.
