Name: aegis-dns-takeover
Author: as-foss

aegis-dns-takeover is agent-read markdown (skill) from as-foss/aegis-skills: Audit playbook module for DNS attack surface and subdomain takeover (CWE-350), covering claimed-hostname inventory extraction from repo/IaC artifacts, dangling-record reasoning from decommission asymmetry, provider claim-table fingerprinting for authorized live verification, zone-hygiene review, and TTL-aware safe-decommission remediation..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version

mdr add as-foss/aegis-skills/aegis-dns-takeover@git:20260826.9702747

Exact content

mdr add as-foss/aegis-skills/aegis-dns-takeover@sha256:e30995e60120b7ee

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
