Cloud asset discovery
When it applies
Recon on an org where a lot of surface lives in the cloud. Mapping the cloud footprint surfaces storage exposure, forgotten apps, and IP ranges that feed the cloud-specific skills.
Why it works
Cloud resources use predictable naming and public namespaces (S3 bucket names are global; app
services use *.azurewebsites.net, *.appspot.com, etc.). Permuting the org name across providers
reveals assets that aren't linked from the main site.
Method
- Permutation sweep:
cloud_enum -k <company> -k <company>-prod -k <brand>to check AWS S3, Azure blobs/apps, and GCP buckets/apps for names derived from the org. - From existing assets: resolve subdomains/CNAMEs (→
recon-subdomain-enum,recon-dns-analysis) for cloud endpoints (*.s3.amazonaws.com,*.blob.core.windows.net,*.cloudfront.net). - IP ranges / ASN: find the org's ASN and cloud IP ranges; identify origin IPs behind CDNs.
- Storage exposure: feed discovered buckets/containers to
cloud-s3-exposure(list/read/write test). - Certificate transparency + favicon/Shodan (→
recon-osint) to catch cloud-hosted apps.
Gotchas
- Stay in scope — cloud recon surfaces third-party SaaS and unrelated tenants; verify ownership.
- Shared CDNs (Cloudflare/CloudFront) are not the org's infra — don't attack the CDN; find origin.
- Anonymous bucket testing must be minimal (list/read a marker) — see
cloud-s3-exposurefor care.
