# Multi-Cloud Dangling DNS

## Overview

Cloud and SaaS tear-downs leave DNS behind. The record still sits in your zone, the resource is gone, and anyone who claims that hostname can serve content on a name your users and certificates already trust. Public fingerprint scanners catch many of those records. They miss gone cloud infra that never matches a can-i-take-over-xyz signature.

This is a standing check for [exposure management](/use-cases/exposure-management). You enable the clouds you care about, run BHUSA 2026 Arsenal findmytakeover for zone-diff dangling detection, and get a findings report you can re-run on a schedule when cloud accounts or zones change.

It sits next to the library [Subdomain Takeover Scanner](/library/subdomain-takeover-scanner) (public fingerprint bar). This Collection unit is the Arsenal multi-cloud path: vault variables and secrets for AWS, GCP, Azure, and Cloudflare feed a config assembler, then findmytakeover. You can also edit the bind scripts directly. Clouds stay off until you turn them on; the report says so instead of returning a silent empty result.

## Pipeline

1. Optional bind scripts pull vault flags and secrets for AWS, GCP, Azure, and Cloudflare (FMT_* variables and secret tokens).
2. Optional excludes-domains supplies domains to skip.
3. assemble-fmt-config merges bind folders and excludes into a findmytakeover config file.
4. findmytakeover runs with that config and `verify-dns` defaulting to true (resolve third-party SaaS fingerprints to confirm NXDOMAIN).
5. report turns the findmytakeover folder into the findings evidence report.

## Inputs

- **Vault variables (FMT_*_ENABLED, accounts).** Non-secret switches and account identifiers that enable each cloud provider path. Defaults leave providers off until you set them, or you edit the bind scripts.
- **Vault secrets (FMT_* keys and tokens).** Credentials for the providers you enable. Vault chips are already wired; you can also paste values on the node.
- **excludes-domains.** Optional list of domains to omit from the scan.
- **verify-dns.** Default `true` on findmytakeover. Leave on unless you mean to skip DNS verification of SaaS fingerprints.

## Outputs

- **findmytakeover findings folder.** Raw Arsenal tool output for the configured cloud DNS paths.
- **Findings report.** Scripted report over that folder for review and export.
- **Incomplete-config signal.** When no provider is enabled yet, the report surfaces `cloud_config_required` rather than pretending the multi-cloud check completed.

## Integrations

- [findmytakeover](/tools/findmytakeover) (BHUSA 2026 Arsenal)

## Sample output

Sample shape from a smoke-style pack when cloud providers are still disabled (not a live KPI).

```jsonl
{"tool":"findmytakeover","severity":"medium","title":"FindMyTakeover cloud config required","kind":"gate","remediation":"Enable FMT_*_ENABLED for the providers you want, mount vault secrets or edit the bind scripts, and re-run."}
{"workflow":"multi-cloud-dangling-dns","mode":"default","note":"No cloud enabled yet"}
```

Once a provider is on, findings name dangling zone or SaaS targets from that cloud.

## FAQ

### How is this different from Subdomain Takeover Scanner?

That workflow is the public fingerprint bar: [subfinder](/tools/subfinder), [dnsx](/tools/dnsx), [subzy](/tools/subzy), and [nuclei](/tools/nuclei) takeover templates. This Collection unit is Arsenal findmytakeover against cloud DNS you enable through vault bind scripts or by editing those scripts.

### What happens if I do not supply cloud credentials?

Providers stay off and the report says cloud config is required, instead of a silent empty multi-cloud result. Set Vault `FMT_*` or edit the bind scripts, then run again.

### Does a finding mean the subdomain is claimable?

No. The run surfaces dangling or takeover candidates from findmytakeover. Whether a hostname is claimable depends on the provider registration rules. Treat output as triage input, not a claimability verdict.

### How often should I run this?

On a schedule when cloud DNS and accounts change often enough to leave stale records. Weekly or tighter for active multi-cloud estates. Re-run after large decommissions.

### Does this send traffic to the target?

findmytakeover talks to the cloud DNS and infra APIs you enable. With `verify-dns` on, it also resolves third-party SaaS fingerprints (NXDOMAIN checks). It is not a mass HTTP crawl of your web estate.

## Related workflows

- [Subdomain Takeover Scanner](/library/subdomain-takeover-scanner). Reach for this instead when you only need the public fingerprint path and do not want multi-cloud vault bindings.
- [Subdomain Enumeration Workflow](/library/full-subdomain-enumeration). Reach for this instead when you need a complete subdomain list first, because dangling checks only mean something against an inventory you trust.
