From Random to Semantic Fuzzing
13.1🔒What Is API Fuzzing?Fuzzing is the practice of sending unexpected, malformed, or malicious inputs to an application to discover bugs, crashes, and security…
13.2🔒Fuzzing Technique ComparisonThe key difference is intent. Random fuzzing asks "what happens if I send garbage?" Semantic fuzzing asks "what happens if I send something…
13.3🔒The Seven Fuzzing CategoriesAI generates payloads in seven categories, each targeting a different vulnerability class:
13.4🔒Anomaly DetectionAfter sending fuzz payloads, you need to detect which responses indicate vulnerabilities:
13.5🔒Severity Classification
13.6🔒Key Takeaways- Semantic fuzzing generates structurally valid payloads designed to trigger specific vulnerability classes - Seven categories cover the…
13.7🔒ExercisesExercise 13.1 (Starter): For a user registration endpoint with fields username, email, password, and age, write five fuzz payloads for each…
13.8🔒Career Translation- Designed and implemented a semantic API fuzzing strategy covering 7 vulnerability categories (SQL injection, XSS, boundary values, type…
13.9🔒Q&AInterview Depth CheckPrompt: Explain the difference between random fuzzing and semantic fuzzing for APIs. When is each appropriate? What a strong answer should…
