  - "Censys uses POST with JSON body + Basic Auth; Shodan/ZoomEye use GET with key param/header"

patterns-established:
  - "IoT scanner source pattern: GET/POST to device search API, parse JSON matches, emit Finding per hit"

# Phase 12 Plan 01: Shodan, Censys, ZoomEye IoT Scanner Sources Summary

**Three IoT device scanner recon sources searching Shodan host/search, Censys v2 hosts/search, and ZoomEye host/search for exposed LLM endpoints**

## Performance

- **Duration:** 3 min
- **Started:** 2026-04-06T09:21:40Z
- **Completed:** 2026-04-06T09:24:28Z
- **Tasks:** 2
- **Files modified:** 6

## Accomplishments
- ShodanSource queries /shodan/host/search with API key param, emits findings per IP:port match
- CensysSource POSTs to /v2/hosts/search with Basic Auth (APIId:APISecret), emits findings per host hit
- ZoomEyeSource queries /host/search with API-KEY header, emits findings per IP:port match
- All three sources disabled when credentials empty, use shared retry Client, respect LimiterRegistry

## Task Commits

Each task was committed atomically:

1. **Task 1: Implement ShodanSource, CensysSource, ZoomEyeSource** - `f5d8470` (feat)
2. **Task 2: Unit tests for Shodan, Censys, ZoomEye sources** - `6443e63` (test)

## Files Created/Modified
- `pkg/recon/sources/shodan.go` - ShodanSource with /shodan/host/search API integration
- `pkg/recon/sources/censys.go` - CensysSource with POST /v2/hosts/search + Basic Auth
- `pkg/recon/sources/zoomeye.go` - ZoomEyeSource with /host/search + API-KEY header
- `pkg/recon/sources/shodan_test.go` - 4 tests: enabled, empty key, sweep findings, ctx cancel
- `pkg/recon/sources/censys_test.go` - 4 tests: enabled, empty creds, sweep findings, ctx cancel
- `pkg/recon/sources/zoomeye_test.go` - 4 tests: enabled, empty key, sweep findings, ctx cancel

## Decisions Made
- Shodan, Censys, ZoomEye use bare keyword queries (default formatQuery case) -- no queries.go changes needed
- Censys uses POST with JSON body and Basic Auth; Shodan uses API key as query param; ZoomEye uses API-KEY header

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered
None

## User Setup Required
None - no external service configuration required.

## Next Phase Readiness
- Three IoT scanner sources ready for RegisterAll wiring in Plan 12-04
- Same pattern applies to remaining Phase 12 sources (FOFA, Netlas, BinaryEdge)
