    Course 38 - Web Security Known Web Attacks | Episode 2: RCE Filter Bypassing and JSON Hijacking

    In this lesson, you’ll learn about: bypassing weak RCE filters and understanding JSON hijacking (legacy browser vulnerability)1. Why RCE Filters Fail🔹 Common mistake:Developers block specific characters (like ;)🔹 Problem:Attack surface is much larger than one delimiter👉 Key Insight Blacklisting single characters is not real security2. Alternative Command Operators🔹 Even if ; is blocked, others exist:&& → execute if first succeeds|| → execute if first fails| → pipe output& → background execution👉 Key Insight There are multiple ways to chain commands, not just one3. Encoding to Bypass Filters🔹 Web applications often filter raw characters🔹 Bypass technique:Use URL encoding🔹 Example:&& → %26%26👉 Key Insight Filters that don’t normalize input can be bypassed easily4. Logic-Based Exploitation🔹 Operator behavior matters:&& → requires success|| → requires failure🔹 Attacker strategy:Force first command to fail → trigger second👉 Key Insight Exploitation is about logic control, not just syntax5. Core Defense Principle🔹 Problem:Input filtering ≠ protection🔹 Real solution:Never pass user input to system commands👉 Key Insight Eliminate the sink, not just sanitize input6. What is JSON Hijacking🔹 Definition:A client-side data theft attack exploiting browser behavior🔹 Related concept:Similar to Cross-Site Request Forgery (CSRF)👉 Key Insight It abuses authenticated requests + weak browser protections7. How JSON Hijacking Works (Conceptually)🔹 Key idea:🔹 Attack flow:Victim is logged inAttacker loads sensitive API via Browser sends cookies automaticallyData is exposed to attacker-controlled logic👉 Key Insight Same-Origin Policy historically did not fully protect script loading8. The Role of JavaScript InternalsUsing JavaScript:🔹 Technique:Override object behavior (e.g., setters)Intercept sensitive values during parsing👉 Key Insight Attackers abused how JavaScript handled object properties9. Why JSON Hijacking Worked (Historically)🔹 Root causes:Weak SOP enforcement for scriptsBrowsers executing JSON as JavaScriptSensitive data returned as raw JSON arrays👉 Key Insight It was a browser + API design flaw combination10. Why It’s Mostly Fixed Today🔹 Modern protections:Strict Same-Origin PolicyCORS enforcementJSON responses require proper headersSafer browser engines👉 Key Insight This is now mostly a legacy vulnerability11. How to Prevent JSON Hijacking🔹 Best practices:Use proper Content-Type: application/jsonAvoid returning raw arrays (wrap in objects)Require authentication headers (not just cookies)Implement CSRF protections👉 Key Insight Modern API design prevents this class of attack12. Big Security Lessons🔹 From RCE:Never trust user inputAvoid system command execution🔹 From JSON Hijacking:Don’t rely on browser behaviorAlways enforce server-side protections👉 Key Insight Security failures often come from incorrect assumptionsKey TakeawaysRCE filters are easily bypassed with alternative operators and encodingLogical execution flow is key to exploitationJSON hijacking exploited legacy browser behaviorModern defenses have largely mitigated itSecure design > reactive filteringBig PictureYou are learning:👉 How attackers bypass naive defenses 👉 How browser and server interactions can be abused 👉 How modern security practices evolved from past vulnerabilitiesMental ModelWeak filter → bypass → command execution Weak browser policy → data exposure → session abuse You can listen and download our episodes for free on more than 10 different platforms: https://linktr.ee/cybercode_academy

  2. Course 38 - Web Security Known Web Attacks | Episode 1: Guide to Remote Command Injection

    1 day ago

    Course 38 - Web Security Known Web Attacks | Episode 1: Guide to Remote Command Injection

    In this lesson, you’ll learn about: Remote Command Execution (RCE), blind exploitation techniques, and defensive strategies against command injection1. What is Remote Command Execution (RCE)🔹 Definition:A vulnerability where user input is executed as an OS command🔹 Common in:Python → os.systemNode.js → execPHP → shell_exec👉 Key Insight RCE = user controls what the server executes2. Root Cause of RCE🔹 Problem:Untrusted input passed directly into system commands🔹 Example:ping 127.0.0.1 🔹 Vulnerable usage:ping 👉 Key Insight No validation = full command injection risk3. Command Injection via Delimiters🔹 Common delimiter:; → separates commands🔹 Example attack:127.0.0.1; ls 👉 Result:First command runsSecond command executes attacker payload👉 Key Insight Delimiters allow attackers to chain commands4. Other Command Operators🔹 Logical operators:&& → run if first succeeds|| → run if first fails& → run in background| → pipe output👉 Key Insight Filtering one operator ≠ blocking exploitation5. Blind RCE (No Output Scenario)🔹 Problem:Application does NOT return command output🔹 Solution:Use timing-based detection🔹 Example:ping -c 10 127.0.0.1 👉 Observation:Response delay confirms execution👉 Key Insight Time delays = proof of execution6. Detection Strategy🔹 Steps:Inject payloadMonitor response timeCompare delays👉 Key Insight Blind RCE ≈ Blind SQL Injection (time-based)7. Filter Evasion Techniques (High-Level)🔹 Problem:Input filters block simple payloads🔹 General bypass ideas:Use alternative separatorsChange encoding (e.g., newline %0A)Modify payload structure👉 Key Insight Defense must be comprehensive, not pattern-based8. Injection Context Matters🔹 Input placement:Beginning of commandMiddle of commandEnd of command👉 Each requires different payload structure👉 Key Insight Exploitation depends on context, not just payload9. Real Risk of RCE🔹 Impact:Full server compromiseData exfiltrationPrivilege escalation👉 Key Insight RCE is one of the most critical vulnerabilities10. Prevention Strategies🔹 Secure coding practices:Never pass raw user input to system commandsUse safe APIs instead of shell executionApply strict input validationEscape arguments properly🔹 Example (safe approach):Use parameterized system calls instead of string concatenation👉 Key Insight Prevention > detection11. Defense in Depth🔹 Additional protections:Least privilege for processesSandboxingMonitoring and loggingWeb Application Firewalls (WAFs)👉 Key Insight Security should exist in multiple layersKey TakeawaysRCE happens when user input reaches system executionDelimiters and operators enable command injectionBlind RCE relies on timing-based detectionFilters alone are not enoughSecure coding and validation are criticalBig PictureYou are learning:👉 How attackers exploit command execution 👉 How to detect hidden vulnerabilities 👉 How to build secure backend systemsMental ModelUser input → unsafe execution → injected command → system compromise You can listen and download our episodes for free on more than 10 different platforms: https://linktr.ee/cybercode_academy

    2 days ago

    Course 37 - Building Web Apps with Ruby On Rails | Episode 18:Navigating GraphQL and the Graphiti Middle Ground

    In this lesson, you’ll learn about: REST limitations, GraphQL fundamentals, and the hybrid approach with Graphiti1. The Problem with REST APIsUsing REST:🔹 Key limitations: OverfetchingClient receives more data than neededUnderfetchingRequires multiple requests to get all dataNo strict typingErrors happen at runtimeHeavy reliance on documentation👉 Key Insight REST is simple and scalable—but not always efficient2. Example of Overfetching🔹 Request:GET /users/1 🔹 Response:{ "id": 1, "name": "John", "email": "john@example.com", "address": "...", "preferences": "...", "settings": "..." } 👉 Problem: Client may only need name👉 Key Insight REST responses are fixed by the server, not flexible for clients3. Introducing GraphQLUsing GraphQL:🔹 What it solves: Clients request exactly what they need🔹 Example query:{ user(id: 1) { name } } 👉 Response:{ "data": { "user": { "name": "John" } } } 👉 Key Insight GraphQL eliminates overfetching and underfetching4. GraphQL Schema (Core Concept)🔹 Schema: Defines types and relationshipsActs as a contract between client and server🔹 Example:type User { id: ID name: String email: String } 👉 Key Insight GraphQL is strongly typed, unlike REST5. Queries vs Mutations🔹 Queries (read data):{ users { name } } 🔹 Mutations (write data):mutation { createUser(name: "John") { id } } 👉 Key Insight GraphQL separates read and write operations clearly6. Testing with GraphiQL🔹 Tool: GraphiQL🔹 Features: Run queries in browserExplore schemaDebug 👉 Key Insight GraphiQL improves developer experience significantly7. Downsides of GraphQL🔹 Trade-offs: No native HTTP cachingMore complex setupBoilerplate codeNo strict naming conventions👉 Key Insight GraphQL flexibility comes with added complexity8. Introducing Graphiti (Hybrid Approach)Using Graphiti:🔹 Goal: Combine REST simplicity + GraphQL flexibility🔹 Features: FilteringSortingIncluding relationships👉 Key Insight Graphiti gives you flexibility without abandoning REST9. Graphiti Resources🔹 Concept: Define API behavior using “Resources”🔹 Example:class UserResource ApplicationResource attribute :name, :string end 👉 Key Insight Resources act like a structured API layer10. REST vs GraphQL vs Graphiti🔹 REST: SimpleFastLimited flexibility🔹 GraphQL: FlexiblePrecise data fetchingMore complex🔹 Graphiti: Balanced approachKeeps HTTP benefitsAdds flexibility👉 Key Insight There is no perfect solution—only trade-offs11. When to Use Each🔹 Use REST: Simple APIsStandard CRUD apps🔹 Use GraphQL: Complex frontend needsMultiple data sources🔹 Use Graphiti: Want flexibility + REST structure👉 Key Insight Choose based on project complexity and team needsKey Takeaways REST suffers from overfetching and lack of typingGraphQL provides flexible, precise queriesGraphQL introduces complexity and trade-offsGraphiti offers a middle-ground solutionAPI design is about balancing performance, flexibility, and simplicity You can listen and download our episodes for free on more than 10 different platforms: https://linktr.ee/cybercode_academy

    3 days ago

    Course 37 - Building Web Apps with Ruby On Rails | Episode 17:Mastering Versioning and Pagination

    In this lesson, you’ll learn about: API pagination, versioning strategies, and building scalable Rails APIs1. Why Pagination Is EssentialUsing Ruby on Rails APIs:🔹 Problem: Returning large datasets (thousands of records)Slow responses + heavy database load🔹 Solution: Break data into pages (chunks)👉 Key Insight Pagination improves performance, speed, and user experience2. How Pagination Works (Limit & Offset)🔹 Core idea: limit → how many records per pageoffset → where to start🔹 Example:LIMIT 10 OFFSET 20 👉 Meaning: Skip first 20 recordsReturn next 10👉 Key Insight Pagination is just controlled slicing of data3. Pagination in Rails🔹 Basic example:@users = User.limit(10).offset(20) 🔹 With params:@users = User.limit(params[:limit]).offset(params[:offset]) 👉 Key Insight You can fully control pagination from the client4. Using Pagination Gems🔹 Popular tools: will_paginateKaminari🔹 Example (Kaminari):@users = User.page(params[:page]).per(10) 👉 Key Insight Gems simplify pagination logic and add helpers5. Benefits of Pagination🔹 Advantages: Faster database queriesReduced memory usageBetter frontend performance👉 Key Insight Small responses = faster APIs6. Introduction to API Versioning🔹 Problem: APIs evolve over timeChanges can break old clients🔹 Solution: Maintain multiple API versions👉 Key Insight Versioning protects backward compatibility7. Content Negotiation (Accept Header)🔹 Client request:Accept: application/vnd.myapp.v1+json 🔹 Server behavior: Detect versionReturn matching response👉 Key Insight Client specifies the version, server adapts8. Versioning with Namespaces🔹 Structure:/app/controllers/v1/users_controller.rb /app/controllers/v2/users_controller.rb 🔹 Example:module V1 class UsersController ApplicationController end end 👉 Key Insight Each version has isolated logic9. Routing with Version Constraints🔹 Example:namespace :v1 do resources :users end 👉 Advanced: Use constraints to switch versions dynamically👉 Key Insight Routing determines which version is executed10. Default API Version🔹 Problem: Client doesn’t specify version🔹 Solution: Set fallback version (e.g., V1)👉 Key Insight Always ensure API still works without explicit version11. Pagination + Versioning Together🔹 Example:/api/v1/users?page=2&per_page=10 👉 Key Insight Combine both for scalable and flexible APIsKey Takeaways Pagination reduces load and improves speedUse gems like Kaminari or will_paginateVersioning prevents breaking existing clientsUse namespaces and routing constraintsAlways provide a default version You can listen and download our episodes for free on more than 10 different platforms: https://linktr.ee/cybercode_academy

    4 days ago

    Course 37 - Building Web Apps with Ruby On Rails | Episode 16:Templates and Partials for Modular Rails APIs

    In this lesson, you’ll learn about: modular JSON generation, JBuilder templates, and reusable API response structures1. The Problem with as_jsonUsing Ruby on Rails default serialization:🔹 Issue: Models become bloated with formatting logicBusiness logic + presentation logic get mixed🔹 Example problem:def as_json super.merge(custom_data: ...) end 👉 Key Insight Models should handle data, not how data is presented2. Introducing JBuilderUsing JBuilder:🔹 What it does: Moves JSON generation into view templatesKeeps controllers and models clean🔹 File structure:app/views/projects/show.json.jbuilder 👉 Key Insight JBuilder brings the MVC pattern back to balance3. JBuilder Template Basics🔹 Example:json.id @project.id json.project_title @project.title json.description @project.description 🔹 Features: Rename fieldsSelect attributesBuild structured JSON👉 Key Insight You explicitly control every field in the response4. Handling Nested Associations🔹 Example:json.milestones @project.milestones do |milestone| json.id milestone.id json.name milestone.name end 👉 Key Insight JBuilder makes nested data easy and readable5. Adding Derived Data🔹 Example:json.single_day_project @project.start_date == @project.end_date 🔹 Use cases: FlagsCalculationsBusiness logic outputs👉 Key Insight You can enrich API responses without touching the model6. Why JBuilder Is Better Than as_json🔹 With as_json: Logic scattered across modelsHard to maintain🔹 With JBuilder: Centralized JSON structureCleaner, modular design👉 Key Insight Separation of concerns improves scalability7. JBuilder Partials (Reusability)🔹 Problem: Repeating the same JSON structure🔹 Solution: Use partialsjson.partial! "milestones/milestone", milestone: milestone 👉 Key Insight Write once → reuse everywhere8. Creating a Partial🔹 File:app/views/milestones/_milestone.json.jbuilder 🔹 Example:json.id milestone.id json.name milestone.name 👉 Key Insight Partials act like reusable components for JSON9. Benefits of Partials🔹 Advantages: Consistency across endpointsEasy updatesReduced duplication👉 Key Insight Change in one place → updates everywhere10. Clean API Architecture with JBuilder🔹 Controller:render :show 🔹 View (JBuilder): Handles full JSON structure🔹 Model: Only business logic👉 Key Insight Each layer has a single responsibilityKey Takeaways Avoid overloading models with as_jsonUse JBuilder for structured, readable JSONTemplates control formattingPartials eliminate duplicationImproves maintainability and scalability You can listen and download our episodes for free on more than 10 different platforms: https://linktr.ee/cybercode_academy

    5 days ago

    Course 37 - Building Web Apps with Ruby On Rails | Episode 15: Multi-format Controllers and Custom JSON Serialization

    In this lesson, you’ll learn about: multi-format responses, JSON serialization, and building clean, reusable Rails API controllers1. Multi-Format Controller ResponsesUsing Ruby on Rails:🔹 Problem: Different clients need different formatsBrowser → HTMLMobile app → JSONExternal systems → XML🔹 Solution: Use respond_todef show @user = User.find(params[:id]) respond_to do |format| format.html format.json { render json: @user } format.xml { render xml: @user } end end 👉 Key Insight One controller action can serve multiple clients efficiently2. How Clients Choose the Format🔹 Methods: HTTP Accept headerURL extension (.json, .xml)🔹 Example:GET /users/1.json 👉 Key Insight The client—not the server—decides the response format3. The Serialization Pipeline🔹 Step 1: Data Preparation Convert model → Ruby hash🔹 Step 2: Data Transformation Convert hash → JSON string👉 Key Insight Serialization is a two-step process, not a single action4. as_json vs to_json🔹 as_json: Returns a Ruby hashUsed for customization🔹 to_json: Converts to JSON string🔹 Best practice:render json: @user 👉 Key Insight Let Rails handle conversion to avoid double encoding5. Why Use render Instead of Manual Conversion❌ Bad:render json: @user.to_json ✅ Good:render json: @user 👉 Key Insight Rails automatically calls serialization methods correctly6. Moving Logic from Controllers to Models🔹 Problem: Controllers become cluttered🔹 Solution: Customize JSON in the modeldef as_json(options = {}) super(only: [:id, :name]) end 👉 Key Insight Fat models + skinny controllers = clean architecture7. Filtering Data for Efficiency🔹 Options: only → include specific fieldsexcept → exclude fieldsrender json: @user, only: [:id, :email] 👉 Key Insight Send only what the client needs → better performance8. Including Associations🔹 Example:render json: @user, include: :posts 👉 Key Insight You can return related data in a single response9. Renaming and Customizing Fields🔹 Example:def as_json(options = {}) super.merge({ full_name: "#{first_name} #{last_name}" }) end 👉 Key Insight APIs should be client-friendly, not database-driven10. Adding Derived Data🔹 Examples: Unix timestampsBoolean flagsComputed valuesdef as_json(options = {}) super.merge({ created_at_unix: created_at.to_i, active: status == "active" }) end 👉 Key Insight APIs can provide ready-to-use data, not raw data11. Clean Architecture Strategy🔹 Controller: Handles request/response🔹 Model: Handles data formatting👉 Key Insight Separation of concerns improves maintainabilityKey Takeaways Use respond_to for multi-format APIsSerialization = prepare + transformPrefer render json: over manual conversionMove formatting logic into modelsCustomize responses for performance and clarityBig PictureYou are building:👉 Flexible APIs for multiple clients 👉 Efficient data responses 👉 Clean, maintainable Rails architectureMental ModelRequest → controller action → choose format → model prepares data → Rails serializes → response sent You can listen and download our episodes for free on more than 10 different platforms: https://linktr.ee/cybercode_academy

    Course 37 - Building Web Apps with Ruby On Rails | Episode 14: From Basic HTTP to JWT Authentication

    In this lesson, you’ll learn about: securing APIs in Rails, authentication strategies, and building a stateless authorization system1. Why API Security MattersUsing Ruby on Rails APIs:🔹 Problem: APIs are publicly exposed endpointsWithout protection → anyone can access or manipulate data🔹 Goal: Ensure only authorized users can interact with resources👉 Key Insight An unsecured API is essentially a “wide-open backend”2. Foundation of API Design🔹 Core features: Multiple response formats (JSON)PaginationAPI versioning🔹 Example:/api/v1/projects?page=1 👉 Key Insight Security must be designed alongside API structure—not added later3. Basic HTTP Authentication (Intro Level)🔹 Rails method:http_basic_authenticate_with name: "admin", password: "secret" 🔹 How it works: Sends username/password with every request🔹 Problems: Credentials sent repeatedlyOften stored or cachedVulnerable if not encrypted👉 Key Insight Good for demos ❌ Not safe for production ❌4. Token-Based Authentication with JWTUsing JSON Web Token:🔹 Structure: HeaderPayloadSignature🔹 Example:xxxxx.yyyyy.zzzzz 🔹 Benefits: Stateless (no server session needed)Secure (signed token)Scalable👉 Key Insight JWT is the industry standard for modern APIs5. Why JWT Is More Secure🔹 Advantages: No repeated credentialsToken can expireCannot be modified without secret key🔹 Protection: Immune to CSRF (no cookies required)👉 Key Insight Security comes from signature verification, not secrecy6. Implementing JWT in Rails🔹 Tool: JWT Ruby Gem🔹 Encoding:JWT.encode(payload, secret_key) 🔹 Decoding:JWT.decode(token, secret_key) 👉 Key Insight The server is the only entity that can generate valid tokens7. Authentication Service🔹 Responsibilities: Handle signupHandle loginGenerate token🔹 Flow: User logs inServer validates credentialsServer returns JWT👉 Key Insight Authentication = verifying identity8. Authorization Layer🔹 Implementation: Add before_action in controllerbefore_action :authorize_request 🔹 Process: Extract token from headersDecode tokenIdentify current user👉 Key Insight Authorization = controlling access9. Request Lifecycle with JWT🔹 Flow: Client sends request with tokenServer validates tokenAccess granted or denied👉 Key Insight Every request is independently verified (stateless system)10. From Open API to Secure System🔹 Before: No identity checkFull data exposure🔹 After: Token requiredUser-specific access control👉 Key Insight Security transforms your API from public → protectedKey Takeaways Basic auth is simple but insecureJWT provides stateless, scalable securitySeparate authentication and authorization logicValidate every request using tokensBig PictureYou are building:👉 A stateless authentication system 👉 A scalable API architecture 👉 A secure backend for mobile/web appsMental ModelUser logs in → server issues token → client stores token → sends with each request → server verifies → grants/denies access You can listen and download our episodes for free on more than 10 different platforms: https://linktr.ee/cybercode_academy

  8. Course 37 - Building Web Apps with Ruby On Rails | Episode 13: From Initial Setup to Advanced UI Interaction

    26 Jun

    Course 37 - Building Web Apps with Ruby On Rails | Episode 13: From Initial Setup to Advanced UI Interaction

    In this lesson, you’ll learn about: system (end-to-end) testing in Ruby on Rails, simulating real browser interactions and validating full user experience1. What Is System (End-to-End) Testing?Using Ruby on Rails:🔹 Definition: Tests the application through a real browser🔹 Difference: Unit → single componentIntegration → backend flowSystem → full user experience (UI + backend)👉 Key Insight System tests replicate real user behavior, including clicks and form inputs2. Testing Infrastructure Setup🔹 Core tools: CapybaraSeleniumChrome WebDriver🔹 Requirements: Install browser driverConfigure system test environment👉 Key Insight System testing requires a real browser automation stack3. Simulating User Behavior🔹 Common actions: click_on → simulate clicksfill_in → fill forms🔹 Example:visit login_path fill_in "Email", with: "test@test.com" fill_in "Password", with: "123456" click_on "Login" 👉 Key Insight Tests should mimic real user actions step by step4. Locators vs CSS Selectors🔹 Locators: Based on labels or text🔹 CSS selectors: Target elements by class or structure🔹 Advanced usage:within(".login-form") do fill_in "Email", with: "test@test.com" end 👉 Key Insight Scoped interactions prevent targeting the wrong elements5. Testing Dynamic UI Features🔹 Examples: Swipe cardsProfile updatesInteractive components🔹 Best practice: Avoid tight coupling to frameworks like Vue.js👉 Key Insight Use generic selectors to keep tests maintainable6. Handling Asynchronous Behavior🔹 Problem: JavaScript loads asynchronously🔹 Solution: Use wait mechanisms🔹 Example:assert_text "Welcome", wait: 5 👉 Key Insight Waiting ensures tests don’t fail بسبب timing issues7. Debugging Tools🔹 Techniques: Take screenshots on failureInspect rendered HTMLAdjust timing🔹 Benefit: Easier root-cause analysis👉 Key Insight Visual debugging is critical in system testing8. Testing Responsive Design🔹 Approach: Change browser resolution🔹 Goal: Validate mobile-first layouts👉 Key Insight System tests should reflect real device experiences9. Performance & Workflow Optimization🔹 Tools: Fixtures (static data)Factories (dynamic data)Parallel testing👉 Key Insight Efficient data handling speeds up large test suites10. Building a Future-Proof Test Suite🔹 Principles: Decouple from frontend frameworksUse reusable test patternsCover full workflows👉 Key Insight Maintainability is as important as test coverageKey Takeaways System tests simulate real browser interactionsCapybara and Selenium power UI testingUse scoped selectors for accuracyHandle async behavior with waitsKeep tests flexible and framework-independentBig PictureThis approach teaches you how to:👉 Validate full user experience 👉 Detect UI and interaction bugs 👉 Ensure frontend and backend work seamlesslyMental ModelLaunch browser → simulate user actions → interact with UI → wait for responses → verify results → debug visually → optimize tests You can listen and download our episodes for free on more than 10 different platforms: https://linktr.ee/cybercode_academy
