Map a website’s exposed services by collecting subdomains, active hosts, and current or historical URLs. Inspect JavaScript and exposed files, prioritize areas for security testing, and monitor new subdomains and GitHub commits.
Guide authorized subdomain takeover assessments involving DNS records that point to unclaimed resources. The skill defines boundaries, suggests further checks, and specifies evidence for takeover feasibility, potential impact, or a report of unsuccessful investigation.
Discover subdomains, live hosts, and URLs to build a prioritized map for web security testing. Includes JavaScript analysis, API specification discovery, and monitoring for new subdomains, JavaScript changes, and GitHub commits.
Fix wildcard subdomain routing for Fastly Compute@Edge services when subdomains resolve but return 500 "Domain Not Found" or empty responses. Use when: (1) TLS subscription "issued" but edge serves default certificate (CN=j.sni-644-default), (2) Fastly domain-v1 create succeeds but subdomain returns 500, (3) Static publisher/PublisherServer returns empty content for subdomain requests, (4) DNS wildcard CNAME resolves to wrong target. Covers TLS configuration SNI endpoint selection (x.sni vs j.sni vs w.sni), DNS trailing dot issues, Fastly domain-v1 activation, and reading from KV store directly when PublisherServer fails for subdomains.

Monitor public Certificate Transparency logs, which record TLS certificates, to spot unexpected issuance and discover subdomains. Use crt.sh data to maintain a certificate inventory, check domain findings against DNS, and configure alerts for suspicious activity.
Investigate subdomain takeover risks caused by DNS records pointing to abandoned services. The skill covers discovery, provider error checks, resource claimability, and evidence collection, then examines potential effects on login flows, shared cookies, and trusted content.
Investigate subdomains, SSL certificates, domain registration details, and DNS records with a Python helper. Run checks across multiple domains, estimate registration availability, and receive structured JSON results without additional packages or API keys.
Review HSTS, a browser policy that keeps site connections on HTTPS. Check response headers, policy duration, and subdomain coverage, guide server or CDN configuration, and explain the precautions needed before enabling browser preloading.
Inspect TLS certificates, DNS records, and email authentication settings, then separate configuration advice from demonstrable vulnerabilities. The skill guides evidence collection and impact assessment for subdomain takeover, client certificate bypass, internal hostname exposure, and email spoofing.
Map an authorized target's subdomains, active websites, and technologies, then organize vulnerability checks with security tools. The skill covers reconnaissance workflows, automated scans, and XSS testing for flaws that let injected scripts run in web pages.
When the user wants to decide domain structure for multiple products or brands—subfolder vs subdomain vs independent domain. Also use when the user mentions "subfolder vs subdomain," "subdirectory vs subdomain," "multiple products domain," "multiple websites," "brand architecture," "branded house," "house of brands," "where to host product," "domain structure," or "hub-spoke domain." For brand SERP, use multi-domain-brand-seo.

OWASP Amass maps an organization's external attack surface: it finds subdomains, IP addresses, netblocks and ASNs from passive sources and active DNS techniques and stores them in an asset database. Use when: comprehensive subdomain enumeration, attack surface discovery, finding forgotten hosts before a pentest, tracking newly appeared assets, building a graph of target infrastructure.

Enumerate subdomains using passive and active techniques (subfinder, amass, chaos, assetfinder, crtsh, DNS brute force). Use when the user has a root domain in scope and needs the full subdomain list before probing.

Detect and exploit subdomain takeover via dangling DNS records pointing to deprovisioned cloud services (S3, GitHub Pages, Heroku, Azure, Shopify, AWS CloudFront, etc.). Use after subdomain enumeration to identify takeover candidates.

Monitors Certificate Transparency (CT) logs to detect unauthorized certificate issuance, discover subdomains via CT data, and alert on suspicious certificate activity for owned domains. Uses the crt.sh API and direct CT log querying based on RFC 6962 to build continuous monitoring pipelines that catch rogue certificates, track CA behavior, and map the external attack surface. Activates for requests involving certificate transparency monitoring, CT log auditing, subdomain discovery via certificates, or certificate issuance alerting.

Web2 recon pipeline — subdomain enumeration (subfinder, Chaos API, assetfinder), live host discovery (dnsx, httpx), URL crawling (katana, waybackurls, gau), directory fuzzing (ffuf), JS analysis (LinkFinder, SecretFinder), continuous monitoring (new subdomain alerts, JS change detection, GitHub commit watch). Use when starting recon on any web2 target or when asked about asset discovery, subdomain enum, or attack surface mapping.

Hunting skill for subdomain takeover vulnerabilities. Includes modern provider fingerprints — Microsoft Azure DevOps `cloudapp.azure.com` regional-pool re-issue (1-click OAuth ATO via wildcard `reply_to`, Binary Security), Zendesk help-desk takeover → email interception → password reset chain (0xprial writeup), Vercel `cname.vercel-dns.com` deleted-project takeover, plus general Fastly CDN service re-attach and S3 dangling-bucket cookie-scope techniques. Use when hunting subdomain takeover — emphasis on ATO-chain primitives (OAuth `redirect_uri`, cookie-domain, email DNS).

Analyze Zeek DNS logs for possible data theft hidden in domain queries. The skill examines unusual character patterns, long labels, distinct subdomains, and query volume, then ranks suspicious domains and produces a JSON evidence report.
Guide a bug bounty investigation from scope checks and asset discovery to vulnerability testing, impact validation, and report writing. Covers web applications, source code, and AI features, with an emphasis on reproducible evidence of real harm.
Support authorized external security reconnaissance, the discovery of exposed systems and information. The skill provides search queries, probe references, secret detection patterns, and scoring guidance to help identify assets and organize findings with evidence and confidence levels.
Inventory old and undocumented API versions, then compare their authentication, request limits, input validation, and exposed fields with current versions. Uses API specifications and archived records to identify overlooked endpoints with weaker security controls.
Guide bug bounty work from asset discovery to validation and reporting, while resolving local locations of security tools, wordlists, and cloned projects. It covers web and AI security testing with an emphasis on demonstrated impact.
