offensive-phishing is agent-read markdown (skill) from snailsploit/claude-red: Phishing campaign execution methodology for authorized red team engagements. Covers end-to-end campaign lifecycle: infrastructure provisioning (GoPhish, SMTP relay configuration, domain acquisition and aging, SPF/DKIM/DMARC alignment), payload delivery vectors (Office macro weaponization, HTA droppers, ISO/IMG container abuse, LNK shortcut hijacking, OneNote embedded payloads, HTML smuggling), email authentication bypass techniques (SPF softfail exploitation, DKIM replay attacks, display name sp.

What the file says
# Offensive Phishing Phishing remains the most reliable initial access vector in red team engagements. You are simulating a real adversary -- your infrastructure, pretexts, and payloads must withstand the same scrutiny that a targeted organization's email security stack applies to inbound mail. This skill walks you through building campaigns that test an organization's human and technical defenses against email-based social engineering. Every technique here assumes you hold explicit written authorization. Document your scope, target lists, and escalation procedures before sending the first email. ## Quick Workflow 1. Register a lookalike domain 4-8 weeks before the engagement; configure DNS records for SPF, DKIM, and DMARC alignment. 2. Stand up GoPhish on dedicated infrastructure; configure SMTP relay through a reputable provider or self-hosted MTA. 3. Develop pretexts based on OSINT -- org announcements, vendor relationships, internal processes. 4. Build or clone landing pages; deploy EvilGinx2 phishlets if MFA bypass is in scope. 5. Craft payloads matched to the target's email security posture (macro-enabled docs, HTML smuggling, ISO containers). …
