Security Considerations

While cloud.microsoft is an established platform, these capabilities require extra vigilance.

File Hosting

cloud.microsoft allows users to upload and share files. Any file you download was uploaded by another user—not the platform operator. Scan downloads with antivirus software and only download from sources you trust.

Form Builder

cloud.microsoft enables anyone to create forms that collect user data. Attackers use this to create fake login pages or payment forms. Never enter passwords or financial information on forms hosted here unless you initiated the process yourself.

Identity Provider

cloud.microsoft provides "Sign in with..." authentication for third-party websites. Attackers create fake login pages that look identical to the real one. Always check the URL bar shows the exact correct domain before entering your password.

Document Hosting

cloud.microsoft hosts documents and pages shared via links. Because the domain is trusted, links pass through email spam filters easily. Attackers exploit this to host fake invoices, login pages, or malware download prompts.

Remember: The platform itself is established, but even established platforms can be abused.
