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…

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

# Hunting scheduled-job and search-path hijacks: what runs, as whom, over what you can write

Automation escalates privilege quietly. A job runs on a timer as a privileged identity, and
if anything it touches is writable by a lesser user, or if it resolves a command through a
path or a wildcard that a lesser user can influence, that user's content runs as the job's
identity. The bug is never the schedule; it is the trust the job places in a writable script,
a writable directory on its search path, an unqualified command name, or a filename that a
wildcard hands to a command as an option. You find it by listing every job, the identity it
runs as, and every input it trusts, then checking which of those inputs a lesser user controls.

## When to use

- You are auditing a host or image for local privilege escalation through automation.
- Periodic jobs, timers, or service-triggered scripts run as a privileged identity.
- Those jobs execute scripts, resolve commands by name, or expand wildcards over directories.

## Scope check

Audit scheduled-job and path escalation only on hosts or images you own or are authorized to

How to install

The exact contents, by fingerprint
mdr add unboundcompute/security-agent-skills/hunting-scheduled-job-and-search-path-hijacks@sha256:7d8df52072f70814

The 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.
