Adversary Infrastructure Tracker

building-adversary-infrastructure-tracking-system

mukul975/Anthropic-Cybersecurity-Skills

Automates tracking of adversary infrastructure by combining passive DNS, certificate transparency, WHOIS, and enrichment APIs to map C2 networks, detect new domains, and continuously update relationships for threat intelligence teams.

Open Source Intelligence Collector

collecting-open-source-intelligence

mukul975/Anthropic-Cybersecurity-Skills

Collects and correlates OSINT about threat actors, infrastructure, and campaigns using tools like Maltego, Shodan, SpiderFoot, and passive DNS/WHOIS lookups, helping analysts enrich CTI reports or prep authorized reconnaissance before red-team engagements.

External Reconnaissance With OSINT

conducting-external-reconnaissance-with-osint

mukul975/Anthropic-Cybersecurity-Skills

Guides security testers through passive OSINT reconnaissance to map an organization’s external attack surface, harvest DNS/infrastructure records, profile personnel, and check leaked credentials before any active probing.

DNS Exfiltration Detection

detecting-dns-exfiltration-with-dns-query-analysis

mukul975/Anthropic-Cybersecurity-Skills

Detect DNS tunneling data exfiltration by analyzing query entropy, subdomain length, query volumes, TXT abuse, and response payload sizes using passive DNS logs, enabling SOC analysts to hunt and validate DNS-based threats.

Hunt DNS Persistence

hunting-for-dns-based-persistence

mukul975/Anthropic-Cybersecurity-Skills

Hunt for DNS-based persistence with SecurityTrails passive DNS, audit logs, and zone transfer reviews to detect hijacks, dangling CNAMEs, wildcard abuse, and unauthorized NS/TXT changes, then report anomalies in JSON with remediation guidance.

API Inventory Discovery

performing-api-inventory-and-discovery

mukul975/Anthropic-Cybersecurity-Skills

Performs comprehensive API inventory and discovery across documented, undocumented, shadow, zombie, and deprecated surfaces by combining passive traffic analysis, active scanning, DNS enumeration, JavaScript parsing, and cloud inventory to map OWASP API9 risks.

Threat Infrastructure Monitoring

tracking-threat-actor-infrastructure

mukul975/Anthropic-Cybersecurity-Skills

Monitors and maps adversary-controlled assets like C2 servers, phishing domains, and staging hosts by combining passive DNS, Shodan/Censys scanning, CT logs, and WHOIS lookups so SOC analysts can track infrastructure over time.
