Security and Modern Use:
Security Risks: SSI can be exploited in phishing attacks. Malicious .shtml files (often sent as email attachments) may contain hidden JavaScript that redirects users to fake login pages to steal credentials.
Deprecated in Modern Development: While still functional, SSI has largely been replaced by more powerful technologies like PHP, JavaScript frameworks (React, Vue), and templating engines (Handlebars, Pug).
Use Cases Today: Primarily found in legacy systems, small websites, or environments where minimal server configuration is preferred.
Note: If you receive an .shtml file as an email attachment, do not open it unless you are certain of its source—this is a common vector for phishing attacks.
