The modern attack chain: Rethinking Google Workspace security in the age of AI – Help Net Security
The Vercel and Composio incidents show that modern workspace attacks can start with OAuth grants instead of email, allowing access to Gmail, Drive, and broader connected systems. The article argues that AI agents using legitimate OAuth access can follow the same dangerous path, so organizations need environment-level controls across email, OAuth, and data access. #Vercel #Composio #OAuth #Gmail #Drive #GoogleWorkspace

Keypoints

  • Vercel and Composio appear to reflect the same attack pattern rather than isolated breaches.
  • OAuth tokens can become the entry point into Google Workspace and survive password resets.
  • Attackers can use access to Gmail and Drive to steal sensitive data and pivot laterally.
  • AI agents can unintentionally follow the same access path when overpermissioned.
  • Defense should focus on the workspace environment, including email, OAuth behavior, and sensitive data controls.
