Skill UI

This skill automates the process of testing for Broken Function Level Authorization (BFLA) vulnerabilities in APIs. It simulates attempts by low-privilege users to access or execute administrative functions and privileged endpoints by manipulating HTTP methods, paths, and credentials. It is essential for comprehensive API security audits and validating Role-Based Access Control (RBAC) enforcement.

This skill guides security testers in identifying excessive data exposure in REST and GraphQL APIs. It involves intercepting API responses and analyzing them for leaked Personally Identifiable Information (PII), internal identifiers, or sensitive business data that the client UI does not display but the API transmits. It maps directly to OWASP API3:2023 Broken Object Property Level Authorization, helping prevent data leaks via over-fetching.

This comprehensive guide details the methodology for identifying and exploiting Insecure Direct Object Reference (IDOR) vulnerabilities. It teaches users how to systematically test broken access control in modern web applications and APIs. By manipulating predictable object identifiers (such as user IDs, order numbers, or document slugs), testers can validate if object-level authorization is properly enforced, preventing unauthorized horizontal or vertical data access.

This skill demonstrates how to exploit JWT algorithm confusion vulnerabilities. It targets APIs that do not strictly enforce the cryptographic algorithm (alg) specified in the token header. Techniques covered include downgrading from asymmetric algorithms (RS256) to symmetric ones (HS256) using the public key as the secret, performing alg:none bypasses, and manipulating key identifiers (kid, jku, x5u) to achieve authentication bypass and token forgery.

A detailed guide on discovering and exploiting Mass Assignment vulnerabilities in REST APIs. Users learn to inject unexpected parameters into API requests (POST, PUT, PATCH) to bypass authorization controls, escalate privileges (e.g., changing 'role'), and modify sensitive fields (e.g., 'balance', 'isAdmin') during security assessments and bug bounty hunting.

This guide details the implementation of robust API abuse detection mechanisms. It covers advanced rate limiting techniques, such as the Token Bucket and Sliding Window algorithms, to defend APIs against DDoS attacks, brute force attempts, and credential stuffing. It emphasizes using distributed stores like Redis for accurate, scalable, and adaptive security controls in an API gateway context.

API Security Posture Management (API-SPM) provides continuous, unified visibility into an organization's entire API attack surface. It automatically discovers, classifies, and risk-scores all APIs—including internal, external, and shadow endpoints. By aggregating findings from various sources (DAST, SAST, runtime logs), it helps enforce security policies, detect configuration drift, and maintain compliance across the entire API lifecycle.

This guide details how to implement comprehensive API security testing using the 42Crunch platform. It performs static audits of OpenAPI specifications (API Audit) and dynamic vulnerability scanning (Conformance Scan) against live APIs. Supports integration into CI/CD pipelines to proactively discover OWASP API Top 10 vulnerabilities, enabling a Shift-Left security approach.

This guide details how to implement multi-layered API threat protection using Google Apigee. It covers critical security policies including JSON/XML content validation, OAuth 2.0 enforcement, SpikeArrest rate limiting, and advanced regex patterns to defend against OWASP Top 10 threats. Ideal for establishing robust API security controls and meeting compliance requirements.

This utility implements comprehensive Cloud Workload Protection (CWPP) by monitoring compute workloads on cloud instances (EC2/GCE). It provides runtime security controls, detecting process anomalies, unauthorized binary execution, cryptomining activity, and suspicious network connections using AWS and Google APIs. Ideal for establishing robust security postures and meeting compliance requirements.

This skill provides comprehensive knowledge on using JSON Web Tokens (JWT) for secure authentication and authorization. It covers implementing various cryptographic signing algorithms (such as HS256, RS256, ES256, and EdDSA), validating signatures, enforcing claim constraints (like expiration time), and implementing robust defenses against common JWT vulnerabilities, including algorithm confusion and the 'none' algorithm attack. Ideal for building secure, scalable web APIs.

This skill covers performing comprehensive vulnerability assessments across diverse environments, including on-premises infrastructure, cloud VMs, and container registries. It leverages standard network protocols like SSH (Linux) and WMI (Windows), coupled with advanced cloud provider APIs for analyzing disk snapshots without requiring local endpoint agents. Ideal for security auditing and compliance checks.
