Comprehensive Linux privilege escalation methodology for offensive security engagements. Covers the full attack surface from a low-privilege shell to root: SUID/SGID binary abuse via GTFOBins, Linux capabilities exploitation (cap_setuid, cap_dac_override, cap_dac_read_search), sudo misconfigurations including NOPASSWD rules and Baron Samedit (CVE-2021-3156), cron job abuse through writable scripts, PATH hijacking, and wildcard injection with tar/rsync/chown. Includes writable /etc/passwd…
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
# Linux Privilege Escalation You have a low-privilege shell on a Linux target. Your objective is to escalate to root through systematic enumeration and exploitation of misconfigurations, vulnerable software, and kernel flaws. This skill provides a structured methodology that moves from passive reconnaissance through increasingly aggressive techniques, prioritizing reliability and stealth. Every engagement starts with situational awareness. Know what you have, what the system exposes, and what defenders can see. Chain low-severity findings into high-impact escalation paths. ## Quick Workflow 1. Run automated enumeration (LinPEAS, linux-exploit-suggester) to surface quick wins. 2. Check sudo permissions, SUID/SGID binaries, and capabilities first -- these are the highest-probability vectors. 3. Enumerate cron jobs, writable scripts, and PATH ordering for hijack opportunities. 4. Inspect file permissions on /etc/passwd, /etc/shadow, service configs, and SSH keys. 5. Check for NFS shares with no_root_squash and Docker group membership. 6. Fingerprint the kernel version and search for applicable kernel exploits as a last resort. …

How to install
mdr add miosa-osa/osa/offensive-linux-privesc@sha256:bfefc36f3848985eThe line at the top of this page pins the label git:20260913.e13b6b8, 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.
