 "notes": "Disclosed by Abnormal Security. The AI platform is infrastructure, not payload: gamma.app is commonly whitelisted, so the lure passes filters, and Gamma's import-from-URL cloning builds the impersonation. Abnormal's point is that employees have no familiarity baseline for newer AI SaaS, so nothing looks wrong. MFA did not help — the AiTM stage validated credentials and captured session cookies in real time. AI Incident Database incident 1068.",
