# CTF Web ## Workflow 1. Normalize targets: identify base URL, exposed ports, path hints, credentials, cookies, and source files. 2. Establish baselines with bounded GET requests for `/`, common paths, linked resources, and obvious endpoints. 3. Detect forms, links with parameters, APIs, redirects, status changes, cookies, and response length changes. 4. Try limited active probes: form submission, SQL error payloads, SSTI arithmetic, path traversal, LFI markers, and simple auth bypass values. 5. Extract candidate flags from every response body and relevant headers. ## Evidence Rules Record URL, method, payload, status, body length, response markers, and extracted flag source. Treat memory or known challenge patterns as hints only. Do not confirm a flag without direct response evidence. ## Output Return structured findings, candidate flags, tool outputs, and next actions. If no flag is found, publish the most suspicious endpoint or parameter for follow-up instead of repeating the same probes.
