Fake Cloud Storage Full Email

    Date: 04/28/2026 

    Severity: High

    Summary

    We identified phishing emails falsely claiming mailbox storage limits are exceeded. They include shortened links that redirect to fake “Cloud” storage pages. The messages use urgent language like “Cloud storage is full” and “Permanent data loss warning.” Users are pressured through multiple redirects to pages mimicking real cloud dashboards. These pages imitate OS elements (e.g., “Activate Windows”) and display full-screen fake system pop-ups. Following the prompts leads to sites selling VPN or antivirus tools, often from firebaseapp-based noreply addresses.
