SIEM Correlation Rule Builder

implementing-siem-correlation-rules-for-apt

mukul975/Anthropic-Cybersecurity-Skills

Crafts Splunk/Sigma-based SIEM correlation rules to detect APT lateral movement by chaining Windows authentication, process execution, and network telemetry across hosts, automating sigma-cli conversion and Splunk ES API deployment.

Zero Knowledge Proof Authentication

implementing-zero-knowledge-proof-for-authentication

mukul975/Anthropic-Cybersecurity-Skills

Implements Schnorr identification and Fiat-Shamir-based non-interactive proofs so servers confirm identity without learning passwords, covering ZKPP, security properties, and practical verification scenarios.

Intercept Mobile Traffic

intercepting-mobile-traffic-with-burpsuite

mukul975/Anthropic-Cybersecurity-Skills

Intercept and analyze mobile app HTTP/HTTPS traffic with Burp Suite to expose insecure APIs, authentication flaws, data leaks, and server vulnerabilities during penetration tests or API security assessments.

Active Directory Investigation

performing-active-directory-compromise-investigation

mukul975/Anthropic-Cybersecurity-Skills

Investigate Active Directory breaches by analyzing authentication logs, Kerberos anomalies, NTDS.dit integrity, Group Policy changes, and privileged group edits to uncover persistence and lateral movement paths.

RESTler API Fuzzing

performing-api-fuzzing-with-restler

mukul975/Anthropic-Cybersecurity-Skills

Automates stateful REST API fuzzing with RESTler by compiling OpenAPI specs, configuring authentication, and running test modes to uncover 500 errors, injection flaws, and authentication bypasses.

Postman API Security Tests

performing-api-security-testing-with-postman

mukul975/Anthropic-Cybersecurity-Skills

Leverages Postman collections, automated scripts, and Newman/ZAP integrations to exercise OWASP API Security Top 10 vulnerabilities across roles and CI/CD pipelines, ensuring authentication, authorization, injection, and data exposure defenses before deployment.

Thick Client Pentest Guide

performing-thick-client-application-penetration-test

mukul975/Anthropic-Cybersecurity-Skills

Performs thick client desktop application pentests by analyzing local storage, binaries, memory, and API traffic with dnSpy, Procmon, Burp Suite, and supporting tools to surface hardcoded credentials, DLL hijacking, insecure encryption, and authentication flaws before release.

Web Application Pentest

performing-web-application-penetration-test

mukul975/Anthropic-Cybersecurity-Skills

Leverages OWASP WSTG processes and Burp Suite to systematically validate web applications for authentication, authorization, input validation, session, and business-logic flaws ahead of deployment or during compliance checks.

Harbor Container Registry Security

securing-container-registry-with-harbor

mukul975/Anthropic-Cybersecurity-Skills

Guides teams through securing a Harbor container registry by enabling TLS, RBAC, vulnerability scanning, content trust, immutable tags, retention policies, and OIDC authentication to ensure only trusted, compliant images are deployed.

API Authentication Testing

testing-api-authentication-weaknesses

mukul975/Anthropic-Cybersecurity-Skills

Tests API authentication mechanisms such as JWT, OAuth, session tokens, API keys, and password policies for weaknesses like missing auth, token leakage, or credential stuffing to harden REST services before launch.

OWASP API Security Testing

testing-api-security-with-owasp-top-10

mukul975/Anthropic-Cybersecurity-Skills

Guides offensive and defensive teams through systematic REST, GraphQL, and gRPC API testing against the OWASP API Security Top 10, covering discovery, authorization flaws, authentication gaps, data exposure, and rate limiting checks with common tooling.

JWT Vulnerability Testing Guide

testing-for-json-web-token-vulnerabilities

mukul975/Anthropic-Cybersecurity-Skills

Assess JWT implementations for algorithm confusion, none bypass, kid/JKU/X5U injections, and weak secrets to detect authentication bypass and privilege escalation risks during API, OAuth/OIDC, or SSO penetration tests.
