Course 3 - Mastering Nuclei for Bug Bounty | Episode 6: Nuclei Fuzzing Techniques: Cluster Bomb, Pitchfork, and Battering Ram

In this lesson, you’ll learn about:Fuzzing with Nuclei — purpose: using custom YAML templates to brute-force or enumerate inputs (usernames, passwords, endpoints, parameters) to find misconfigurations, default creds, or hidden functionality.Template components for fuzzing: define raw request, payloads (wordlists), payload positions, attack type, and matchers (e.g., word: success + status: 200) that mark a successful hit.Cluster‑Bomb (combinatorial) fuzzing:Mechanism: one position is fixed while another iterates through its entire list; repeats for each fixed value (good for username × password lists).Use case: test many passwords per given username.Template note: set attack: clusterbomb, map Parameter A → usernames.txt, Parameter B → passwords.txt.Pitchfork (parallel) fuzzing:Mechanism: iterate multiple lists in lock‑step (1st of list A with 1st of list B, 2nd with 2nd, …).Use case: paired credential lists or aligned parameter sets.Template note: set attack: pitchfork and ensure lists are same length or intended pairing.Battering‑Ram (single payload) fuzzing:Mechanism: use a single wordlist for all fuzz positions or a single targeted parameter.Use case: known username + fuzz many passwords, or reuse same payload across several params.Template note: set attack: batteringram with one payload source.Success detection: combine response checks (e.g., word: "success") with status codes (status: 200) or other fingerprints to reduce false positives. Use extractors to capture useful response data.Practical workflow: validate template YAML, test against staging or safe targets, proxy via Burp for live inspection, run with -debug/-v to see requests/responses.Operational safety & ethics: never run aggressive fuzzing against production/unauthorized targets; throttle requests (rate-limit), respect scope, and document findings (time, payload, matched response) for reproducible PoCs.Tips to improve success rate: tune content-type and headers, handle cookies/session reuse if needed, rotate/parallelize carefully (bulk-size / concurrency), and pre‑filter targets to avoid wasting wordlist attempts on unreachable endpoints.You can listen and download our episodes for free on more than 10 different platforms:https://linktr.ee/cybercode_academy
