Vercel disclosed that attackers used a compromised OAuth token tied to a Vercel employee's Google Workspace account and access to Context.ai to reach some Vercel environments and environment variables that were not marked as sensitive, and the company said a limited subset of customers had Vercel credentials compromised and were told to rotate them. Vercel said sensitive environment variables were not known to be accessed and that it was working with Mandiant, other security firms, Context.ai, and law enforcement while keeping services operational; Context separately said it had identified and stopped an AWS breach last month and later learned the actor likely also compromised OAuth tokens for some consumer users.
