SMTP Injection Generator
Generate SMTP injection payloads for header injection, email spoofing, and MIME smuggling attacks.
SMTP Injection
SMTP injection exploits improper input sanitization in email headers. Header injection adds malicious Bcc/CC/To headers to send spam, email spoofing forges the From address using missing SPF/DKIM/DMARC validation, and MIME smuggling embeds malicious attachments by injecting MIME boundaries. Always enforce strict input validation and use email libraries that prevent header injection. Test only with authorization.
