Phase 12 Plan 03: Cloud Storage Scanners Summary

Four credentialless cloud storage recon sources (S3, GCS, Azure Blob, DO Spaces) with provider-keyword bucket enumeration and config-file pattern detection

Performance

• Duration: 4 min
• Started: 2026-04-06T09:22:08Z
• Completed: 2026-04-06T09:26:11Z
• Tasks: 2
• Files modified: 8

Accomplishments

• S3Scanner enumerates public AWS S3 buckets using S3 ListBucketResult XML parsing
• GCSScanner enumerates public GCS buckets using JSON listing format
• AzureBlobScanner enumerates public Azure Blob containers using EnumerationResults XML
• DOSpacesScanner enumerates public DO Spaces across 5 regions using S3-compatible XML
• Shared bucketNames() generates candidates from provider names + common suffixes
• Shared isConfigFile() detects .env, .json, .yaml, .toml, .conf and similar patterns

Task Commits

Each task was committed atomically:

1. Task 1: Implement S3Scanner and GCSScanner - 47d542b (feat)
2. Task 2: Implement AzureBlobScanner, DOSpacesScanner, and all tests - 13905eb (feat)

Files Created/Modified

• pkg/recon/sources/s3scanner.go - S3 bucket enumeration with XML ListBucketResult parsing
• pkg/recon/sources/gcsscanner.go - GCS bucket enumeration with JSON listing parsing
• pkg/recon/sources/azureblob.go - Azure Blob container enumeration with XML EnumerationResults parsing
• pkg/recon/sources/dospaces.go - DO Spaces enumeration across 5 regions (S3-compatible XML)
• pkg/recon/sources/s3scanner_test.go - httptest tests for S3Scanner
• pkg/recon/sources/gcsscanner_test.go - httptest tests for GCSScanner
• pkg/recon/sources/azureblob_test.go - httptest tests for AzureBlobScanner
• pkg/recon/sources/dospaces_test.go - httptest tests for DOSpacesScanner

Decisions Made

• bucketNames uses provider Name (not Keywords) as base for bucket name generation -- produces more realistic bucket names like "openai-keys" vs "sk-proj--keys"
• HEAD probe before GET to minimize bandwidth on non-public buckets
• Azure iterates a fixed list of common container names within each generated account name
• DO Spaces iterates all 5 supported regions per bucket name
• Tests omit rate limiters (nil Limiters) to avoid test slowness from the 500ms rate limit across many bucket/region combinations

Deviations from Plan

None - plan executed exactly as written.

Issues Encountered

• Azure and DO Spaces tests initially timed out due to rate limiter overhead (9 bucket names x 7 containers = 63 requests at 500ms each). Resolved by omitting rate limiters in tests since rate limiting is tested at the LimiterRegistry level.

User Setup Required

None - no external service configuration required.

Next Phase Readiness

• Four cloud storage scanners ready for RegisterAll wiring
• Sources use same pattern as Phase 10/11 sources (BaseURL override, shared Client, LimiterRegistry)
