Attackers Prompted Vercel's v0 Into Building Their Phishing Sites for Them
In late June and July 2025, Okta Threat Intelligence reported that threat actors were abusing v0, Vercel's generative UI tool, to build and host phishing sites impersonating real sign-in pages, including an actual Okta customer, Microsoft 365, and cryptocurrency companies. Okta researchers reproduced the technique themselves by prompting v0 to 'build a copy of the website login.okta.com.' It was the first time Okta had seen genAI generate the phishing infrastructure itself rather than just the email.
