blind-ssrf-chains skillB

blind-ssrf-chains is agent-read markdown (skill) from dreadnode/capabilities: Escalate blind SSRF to proven impact via internal service canaries, port fingerprinting, chained exploitation targeting Redis, Docker API, Jenkins, and cloud metadata, and attacker-controlled infrastructure for dangling resource claims and redirect servers. Use when blind SSRF is confirmed but you need to demonstrate CIA impact beyond 'I can reach internal hosts.'.

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 dreadnode/capabilities/blind-ssrf-chains@git:20260827.9e5b22d
Exact content
mdr add dreadnode/capabilities/blind-ssrf-chains@sha256:053aefb78294d336

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.
