Security Considerations
While substackcdn.com is an established platform, these capabilities require extra vigilance.
File Hosting
substackcdn.com 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.
Document Hosting
substackcdn.com 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.
