Conduct comprehensive security assessments of SMTP (Simple Mail Transfer Protocol) servers to identify vulnerabilities including open relays, user enumeration, weak authentication, and misconfiguration. This skill covers banner grabbing, user enumeration techniques, relay testing, brute force attacks, and security hardening recommendations. SMTP protocol fundamentals Email architecture (MTA, MDA, MUA) DNS and MX records Network protocols Target SMTP server IP/hostname Written authorization for testing Wordlists for enumeration and brute force 1. SMTP Security Assessment Report - Comprehensive vulnerability findings 2. User Enumeration Results - Valid email addresses discovered 3. Relay Test Results - Open relay status and exploitation potential 4. Remediation Recommendations - Security hardening guidance Identify SMTP servers and versions: Retrieve SMTP server information: Parse banner information: Test available SMTP commands: Key commands to test: Enumerate valid email addresses: Using Metasploit: Using Nmap: Test for unauthorized email relay: Using Metasploit: Test variations: Test for weak SMTP credentials: Using Medusa: Using Metasploit: Test for command injection vulnerabilit
