hunting-dynamic-linker-hijacks skillA

hunting-dynamic-linker-hijacks is agent-read markdown (skill) from unboundcompute/security-agent-skills: Hunt local privilege escalation and code execution through the dynamic loader: a preload environment variable honored across a privilege boundary, a writable directory on the runtime library search path, an embedded run-path that points at a writable or origin-relative location, and libraries loaded by an unqualified name. Covers preload variables that survive a privilege transition through a service manager or delegation rule, world- or group-writable library directories a privileged binary sea.

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 unboundcompute/security-agent-skills/hunting-dynamic-linker-hijacks@git:20260819.61df029
Exact content
mdr add unboundcompute/security-agent-skills/hunting-dynamic-linker-hijacks@sha256:069e26df80905395

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.
