Audit secure-shell trust hygiene, not cipher hardening: a forwarded authentication agent a remote host can abuse to log in as you elsewhere, client configuration or a proxy-command directive influenced by an untrusted source, host-key verification disabled or blind-accepted so a machine-in-the-middle succeeds, and authorized-key entries whose forced command can be escaped or whose source and forwarding are unrestricted. Covers agent-socket exposure on multi-user or untrusted hosts, config and…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Auditing SSH trust and agent forwarding: what a connected host can turn into your identity Secure-shell security is usually discussed as ciphers and key lengths, which are largely solved. The unsolved part is trust: who can use your authentication, whose host key you accept without checking, and whose data shapes your client's behavior. A forwarded agent lets whatever host you land on authenticate as you to everything your key opens; a proxy-command or config entry pulled from an untrusted place runs on your machine or redirects your session; a disabled host-key check turns any network position into a man in the middle; a loose authorized-key entry hands more than intended. You find these by tracing where authentication and configuration flow and asking what a compromised or untrusted endpoint can do with them. ## When to use - You are auditing how users or automation establish secure-shell trust and what it reaches. - Agents are forwarded, host keys are accepted, or client configuration comes from shared sources. - A compromised or multi-tenant endpoint could abuse forwarded authentication or injected config. ## Scope check …

How to install
mdr add unboundcompute/security-agent-skills/auditing-ssh-trust-and-agent-forwarding@sha256:3bf8511ad00d2b4aThe line at the top of this page pins the label git:20260819.61df029, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
