data-exfil skillF

data-exfil is agent-read markdown (skill) from dreadnode/capabilities: AI/LLM data exfiltration techniques via rendered markdown, HTML-in-markdown, tool artifacts, domain encoding, and url_safe bypasses. Use when crafting exfil payloads for AI red teaming, analyzing AI app rendering pipelines for exfil surfaces, bypassing URL filters/sanitizers, or reviewing AI-generated output for exfil risk..

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/data-exfil@git:20260529.8f6ea0e
Exact content
mdr add dreadnode/capabilities/data-exfil@sha256:a2a501290eb6b910

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.
