hunt-tls-network

Hunt TLS/SSL and DNS misconfigurations — missing HSTS (downgrade attack), weak cipher suites, expired/invalid certificates, mTLS bypass, missing SPF/DKIM/DMARC (email spoofing), DNS Zone Transfer (AXFR), dangling CNAME subdomain takeover, CAA records. Most of these are Info/Low on their own — this skill is opinionated about which findings actually pay (spoofable DMARC with delivered-to-inbox proof, AXFR returning internal hosts, dangling-CNAME takeover) versus which get rejected as best-practice noise (missing CAA, missing HSTS with no MitM position). Use during recon to find infrastructure weaknesses, and to TRIAGE them honestly before reporting.

E004: Prompt injection detected in skill instructions.

What this means

Detected a prompt injection in the skill instructions. The skill contains hidden or deceptive instructions that fall outside its stated purpose and attempt to override the agent’s safety guidelines or intended behavior.

Why it was flagged

The document contains detailed, actionable instructions for offensive actions (DNS zone transfers, claiming dangling subdomains and serving canary content, sending spoofed emails to demonstrate DMARC bypass, and mTLS header-injection bypasses) — dual-use guidance that can be used for malicious activity.

W011: Third-party content exposure detected (indirect prompt injection risk).

What this means

The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.

Why it was flagged

The skill’s runtime workflow ingests outsider-authored free text via user/attacker-controlled external inputs it actively fetches at run time (e.g., downloading JSON from `https://crt.sh/...` and parsing/grepping response bodies, and making `curl` requests whose bodies are later used for takeover fingerprinting), so poison can be delivered by whoever authors that content.
