SAML Azure AD Federation

building-identity-federation-with-saml-azure-ad

mukul975/Anthropic-Cybersecurity-Skills

Guides teams through standing up SAML 2.0 federation between on-premises AD/AD FS (or third-party IdP) and Microsoft Entra ID, covering domain conversion, certificates, claims rules, and federated SSO for cloud SaaS apps.

Full-Scope Red Teaming

conducting-full-scope-red-team-engagement

mukul975/Anthropic-Cybersecurity-Skills

Guides planning and executing MITRE ATT&CK-aligned red team engagements from reconnaissance through reporting, emphasizing stealthy payloads, lateral movement, defined objectives like domain dominance and data exfiltration, and the legal/prerequisite controls needed to validate detection and response readiness.

Active Directory DCSync Detection

detecting-dcsync-attack-in-active-directory

mukul975/Anthropic-Cybersecurity-Skills

Hunts for DCSync attacks by monitoring Active Directory replication requests, auditing Event ID 4662, correlating non-domain-controller RPC traffic, and alerting when unauthorized accounts request replication rights to detect credential theft.

DNS Query Exfiltration Detection

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

mukul975/Anthropic-Cybersecurity-Skills

Builds a passive DNS analysis pipeline that flags DNS tunneling attempts by inspecting query entropy, subdomain length, volume spikes, TXT abuses, and response payload sizes so SOCs can detect exfiltrating data hidden in DNS traffic.

DNS Exfiltration Detection with Zeek

detecting-exfiltration-over-dns-with-zeek

mukul975/Anthropic-Cybersecurity-Skills

Analyzes Zeek dns.log to flag DNS tunneling by computing subdomain entropy, long labels, unique counts and query volumes, scoring domains and emitting structured JSON reports for SOC investigations and monitoring validation.

AD CS ESC1 Exploit

exploiting-active-directory-certificate-services-esc1

mukul975/Anthropic-Cybersecurity-Skills

Exploit misconfigured Active Directory Certificate Services ESC1 templates to request certificates as privileged users, then escalate to Domain Admin during authorized red team or pentest work. Includes enumeration, certificate requests, PKINIT authentication, and follow-on domain access.

Broken Link Hijacking

exploiting-broken-link-hijacking

mukul975/Anthropic-Cybersecurity-Skills

Audit web apps for dead external resources, verify claimable domains/cloud assets, and validate broken-link hijacking paths to demonstrate supply-chain and subdomain takeover risks.

noPac Domain Admin Exploit

exploiting-nopac-cve-2021-42278-42287

mukul975/Anthropic-Cybersecurity-Skills

Exploit the noPac chain (CVE-2021-42278/42287) to elevate a standard Active Directory user to Domain Admin by spoofing machine accounts, abusing Kerberos PAC confusion, and automating the DCSync workflow during authorized red-team engagements.

Zerologon Domain Takeover

exploiting-zerologon-vulnerability-cve-2020-1472

mukul975/Anthropic-Cybersecurity-Skills

Automates the Zerologon (CVE-2020-1472) attack flow against Netlogon, showing scanning, exploitation, DCSync and restoration so red teams or defenders can reproduce the vulnerability, assess exposure, and validate detection logic.

Zeek DNS Tunnel Detection

hunting-for-dns-tunneling-with-zeek

mukul975/Anthropic-Cybersecurity-Skills

Analyze Zeek dns.log for long queries, high-entropy subdomains, unusual record types, and query volumes to detect DNS tunneling and covert data exfiltration before it reaches other channels.

Email Authentication Hardening

implementing-dmarc-dkim-spf-email-security

mukul975/Anthropic-Cybersecurity-Skills

Implement SPF, DKIM, and DMARC to stop domain spoofing, verify message integrity, and enforce handling policies; ideal for teams configuring DNS/email servers and monitoring compliance.

Email Authentication Audit

implementing-email-security-with-dmarc-dkim-spf

mukul975/Anthropic-Cybersecurity-Skills

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.
