WXE

WXE (Web eXploitation Expert) is SixHack Academy’s advanced training focused on Bug Bounty and professional-level web security auditing. The goal is to take you from spotting “common” issues to finding vulnerabilities with real impact in modern applications, where APIs, microservices, SPAs, SSO, CDNs, proxies, caches, and complex business flows are part of the environment. The focus here isn’t memorizing checklists, but learning to reason like a bounty hunter: uncover real attack surface, prioritize hypotheses based on strong signals, validate findings with reproducible evidence, and write reports that survive triage.

Throughout the course you’ll work with a practical, structured methodology for real-world environments. You’ll start with advanced recon and mapping to understand how an application is built, where its boundaries are, and which components typically hide bugs. From there you’ll learn to identify risk patterns in HTTP and architecture layers, spot inconsistencies in permissions and state, and build controlled proofs that demonstrate impact without “forcing” the system. Burp Suite remains the core tool, but the workflow expands with JavaScript analysis, API testing, controlled automation, and techniques specifically designed to validate modern, real-world vulnerabilities.

Who is WXE for?

WXE is designed for people who already master the fundamentals of web auditing (WXJ level or equivalent) and want to move into a level where findings are often in the details: parsing differences across layers, poorly defined cache rules, broken authorization in APIs, complex authentication flows, and business logic that fails under realistic conditions. It also fits well if you’ve already tried Bug Bounty programs but want to increase your acceptance rate by producing stronger evidence, clearer impact, and better-argued reports.

What you will learn

We’ll begin with discovery and prioritization techniques used in Bug Bounty. You’ll learn how to extract endpoints from modern applications, interpret signals in responses, headers, and platform behavior, and turn a “this looks odd” into a testable hypothesis. Then we’ll go deeper into real-world architectures with CDNs, proxies, and load balancers, understanding how vulnerabilities emerge from desynchronization, inconsistent normalization, and misconfigured caching.

Next, you’ll dive into practical API security. You’ll work on broken authorization in APIs, excessive data exposure, mass assignment, and common inventory and versioning issues. You’ll also cover frequent modern scenarios such as GraphQL and WebSockets, learning how to test access controls, resolver/channel validation, and design flaws that translate into real impact.

You’ll strengthen another key Bug Bounty area: modern authentication and SSO. You’ll learn how to audit JWT-based flows, OAuth2/OIDC, and session mechanisms in distributed applications, identifying errors that lead to account takeover, privilege escalation, or token exposure. In parallel, we’ll address modern client-side security with an impact-driven approach, including advanced DOM XSS, cross-window communication issues, and cases where the front end becomes a real attack vector due to design or implementation flaws.

Finally, a major part of the course focuses on what truly separates expert profiles: advanced business logic. You’ll learn how to analyze state machines, detect race conditions and TOCTOU issues in critical workflows, understand rate limiting from an abuse perspective, and find multi-tenant bugs where separation between organizations or accounts is not properly enforced.

Vulnerabilities and classes of findings you will learn to detect and validate

Throughout the course you’ll learn how to discover and demonstrate impact for advanced, real-world vulnerabilities such as HTTP Request Smuggling and cross-layer desynchronization, Web Cache Poisoning and Cache Deception, Host Header Injection and header manipulation affecting critical flows, and modern API issues such as advanced BOLA/IDOR, Broken Function Level Authorization, excessive data exposure, and mass assignment. You’ll also work on common attack surfaces in GraphQL and WebSockets, auditing SSO with JWT and OAuth2/OIDC, and impact-focused client-side vulnerabilities such as advanced DOM XSS, postMessage issues, and patterns that can become XS-Leaks depending on the context.

In addition, you’ll practice high-value Bug Bounty findings based on business logic, including race conditions, state bypasses, limit/rate bypass, and workflow abuse, as well as frequent large-program scenarios involving infrastructure and third parties, such as exposed secrets in front-end assets, environment misconfigurations, and safely validating cloud-related impact where applicable.

How to turn advanced findings into accepted reports

WXE places strong emphasis on turning a technical issue into a report that a triager can accept without doubts. You’ll learn how to write reproducible steps, capture evidence in an organized way with requests and responses, justify impact without exaggeration, and propose realistic mitigations. You’ll also learn how to reduce duplicates by focusing on what makes your finding unique, how to present impact chains when appropriate, and how to adapt your reporting style to different programs and security teams.

What you will take away

By the end of WXE you’ll be able to audit modern applications methodically, identify real attack surface, prioritize by likelihood of impact, and validate advanced vulnerabilities with clear proof. You’ll gain a solid Bug Bounty approach that helps you move from isolated findings to consistent results, with well-argued, reproducible, impact-driven reports. You’ll leave with the judgment to navigate modern architectures and a professional workflow that scales to complex programs.

Ethical framework and responsible use

WXE is taught with a strictly educational and professional purpose. The techniques learned must be applied only in labs, on your own systems, or on systems with explicit permission, always respecting scope and program rules. The goal is to improve security, report responsibly, and learn to audit with rigor, not to cause harm or access information without authorization.
