A comprehensive, step-by-step checklist and audit script designed for validating Customer.io integrations before going live. It covers credential verification, email deliverability setup (SPF, DKIM, DMARC), API connectivity smoke tests, campaign readiness, and setting up operational monitoring alerts for a smooth, reliable production launch.

A comprehensive guide and workflow for digital forensics investigators to analyze raw email headers. This tool helps trace the true origin of suspicious emails, verify sender authenticity, and detect advanced spoofing techniques by validating crucial protocols like SPF, DKIM, and DMARC. It covers everything from header parsing to domain infrastructure analysis and IP reputation checks.

This guide details the end-to-end process of conducting a sophisticated spearphishing simulation campaign, mirroring real red team adversary techniques. It covers initial OSINT research and pretext development, building weaponized payloads that bypass security controls, setting up robust email infrastructure (SPF/DKIM/DMARC), executing the campaign in waves, and performing detailed post-campaign metrics analysis for comprehensive security reporting.

This guide details the end-to-end process for executing authorized phishing simulations. It instructs security teams and red teams on designing realistic social engineering pretexts, setting up credential harvesting infrastructure (using tools like GoPhish), and measuring key metrics such as open rates, click-through rates, and credential submission rates. It is crucial for assessing organizational human security awareness and testing email security controls (e.g., DMARC, SPF, DKIM).

This guide details the implementation of SPF, DKIM, and DMARC—the three core pillars of email authentication. It provides a comprehensive workflow, including DNS record setup and best practices, to prevent domain spoofing, validate message integrity, and enforce strong anti-phishing policies across your organization's email system. Essential for building robust email security architecture.

Audits a domain’s email authentication by querying SPF, DKIM, and DMARC DNS records using dnspython, validating syntax/counts, flagging common spoofing risks, and producing remediation guidance.

This guide provides comprehensive security hardening procedures for enterprise Google Workspace environments. It covers advanced topics such as enforcing phishing-resistant Multi-Factor Authentication (MFA), configuring email authentication (DMARC/SPF/DKIM), implementing Data Loss Prevention (DLP), and securing super admin accounts using Advanced Protection Program enrollment. Ideal for achieving high compliance and defending against BEC and phishing attacks.

A comprehensive guide for SOC analysts and digital forensics experts. This skill covers the entire lifecycle of a phishing incident, from initial user report and header analysis (SPF, DKIM, DMARC) to detonating malicious URLs/attachments in sandboxes. It guides users on scoping the attack, identifying impacted users via SIEM/proxy logs, and executing containment measures like email purges.

This comprehensive guide outlines the phased rollout process for DMARC (Domain-based Message Authentication, Reporting, and Conformance). It details moving from monitoring (p=none) through quarantine (p=quarantine) to full rejection (p=reject). Adopting DMARC is critical for anti-spoofing, ensuring that only authorized senders can use your domain, thereby significantly reducing phishing and unauthorized email traffic.

A comprehensive guide for authorized penetration testing to map a target's entire DNS infrastructure. This skill covers advanced techniques including enumerating various DNS record types (A, MX, TXT, SRV), attempting zone transfers (AXFR/IXFR), brute-forcing subdomains, and analyzing security configurations (DNSSEC, SPF, DMARC). It is crucial for identifying the full external attack surface of a target organization.

This expert playbook covers advanced techniques for email header injection and authentication bypass. It details exploiting CRLF vulnerabilities in SMTP headers (e.g., BCC/CC injection, body control) and bypassing modern email security standards like SPF, DKIM, and DMARC. Essential for penetration testing of contact forms, email APIs, and password reset workflows.
