hunting-scheduled-job-and-search-path-hijacks skillA

hunting-scheduled-job-and-search-path-hijacks is agent-read markdown (skill) from unboundcompute/security-agent-skills: Hunt local privilege escalation through scheduled jobs and the paths privileged processes trust: periodic and timer jobs whose script, or a file or directory they read, is writable by a lower-privileged user; commands invoked by an unqualified name resolved through a writable search-path entry; and argument injection where a command expands a shell wildcard over a directory an attacker can write to, so a file named like an option (a leading-dash filename) becomes a command-line flag. Covers writ.

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-scheduled-job-and-search-path-hijacks@git:20260819.61df029
Exact content
mdr add unboundcompute/security-agent-skills/hunting-scheduled-job-and-search-path-hijacks@sha256:7d8df52072f70814

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.
