Security Considerations

While hackmd.io is an established platform, these capabilities require extra vigilance.

Document Hosting

hackmd.io 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.

User-Generated Content

hackmd.io hosts content created by its users, not the platform operator. Individual posts, profiles, or pages may contain scams, misinformation, or phishing attempts that the platform hasn't yet detected or removed.

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