Skill UI

An expert developer specializing in secure backend coding practices, vulnerability mitigation, and robust API design. Proficient in preventing common attacks such as SQL injection, XSS, and CSRF. Covers comprehensive areas including input validation, authentication mechanisms (OAuth 2.0, MFA), database security, and implementing necessary security headers (CSP, HSTS) for building secure-by-design applications. Ideal for implementing security fixes or building new, hardened backend services.

A comprehensive guide to implementing robust user authentication flows using Clerk. Learn to set up sign-up and sign-in pages, integrate OAuth social logins (Google, GitHub, Apple), and customize the UI entirely. This guide covers both quick pre-built component usage and advanced custom form implementation with full error handling and MFA support, ideal for building modern SaaS applications.

Validating Authentication Implementations assesses authentication mechanisms like JWT, OAuth, sessions, and API keys against security standards, then reports vulnerabilities and recommendations for password policy, MFA, token handling, and session security.

This comprehensive guide details how to implement Single Sign-On (SSO) for Google Workspace using the SAML 2.0 protocol. It guides administrators through connecting a third-party Identity Provider (IdP) like Okta or Azure AD to centralize authentication, enforce MFA, and manage access policies across the organization.

Configure Azure AD Privileged Identity Management via Microsoft Graph API to enumerate eligible and active assignments, request just-in-time activations, audit logs, and enforce MFA or approval policies for zero-trust privileged access scenarios.

EvilGinx3 is an advanced Adversary-in-the-Middle (AiTM) framework designed for red teaming simulations. It goes beyond traditional credential harvesting by acting as a transparent proxy to intercept the entire authentication flow, including session cookies and Multi-Factor Authentication (MFA) tokens. This capability allows security professionals to assess the robustness of an organization's security posture against sophisticated account takeover attacks.

A comprehensive guide for building a FIDO2/WebAuthn relying party server using python-fido2. This skill covers the entire lifecycle of passwordless authentication, including secure credential registration (enrollment of hardware keys like YubiKey and resident passkeys) and robust authentication ceremonies. It is essential for migrating traditional password-based systems to phishing-resistant Multi-Factor Authentication (MFA).

This skill provides comprehensive guidance on implementing robust data governance and security guardrails within Snowflake. It covers advanced features such as network rules, mandatory authentication policies (MFA, Key Pair), session timeouts, and statement-level controls. Use this when enforcing strict security policies, achieving regulatory compliance, or structuring robust data access controls for a Snowflake environment.

This guide details essential security best practices for Snowflake data warehouses. It covers implementing network policies, managing key rotation, enabling Multi-Factor Authentication (MFA), and securing credentials using secret managers. Use this comprehensive resource to audit security configurations, restrict network access, and enforce least-privilege access within your Snowflake environment.

A comprehensive playbook for identifying authentication vulnerabilities in web applications. Covers advanced topics including SQL injection login bypass, predictable password reset tokens, account enumeration techniques, multi-factor authentication bypass, and brute-force resistance checks. Essential for penetration testers assessing login mechanisms and session management.

Review and harden AWS IAM policies following security best practices and least privilege principles. Includes commands for policy analysis, MFA enforcement, access key management, and role analysis to secure cloud infrastructure access.

Offensive security skill for hunting MFA and 2FA bypass flaws: workflow skipping, OTP replay, response tampering, prefix-oracle guessing, and race conditions on verification endpoints. Requires written authorization.
