Linux Privilege Escalation

This walks you through systematic privilege escalation on Linux systems once you've already got a low-privilege shell. It covers the standard attack surface: kernel exploits, sudo misconfigurations, SUID binaries, capabilities, cron jobs, and PATH hijacking. The workflow is thorough, from basic enumeration commands through automated tools like LinPEAS, then into specific exploitation techniques with code snippets for LD_PRELOAD attacks, capability abuse, and writing malicious cron scripts. It's structured as a penetration testing playbook rather than a conversational assistant task. You need proper authorization before running any of this. The examples are concrete and pull from real references like GTFOBins, which makes it genuinely useful for authorized security assessments or red team exercises where you need to demonstrate what's exploitable on a hardened system.

⚠️ AUTHORIZED USE ONLY This skill is for educational purposes or authorized security assessments only. You must have explicit, written permission from the system owner before using this tool. Misuse of this tool is illegal and strictly prohibited.

Mandatory confirmation gate Before running any command that probes, exploits, changes, persists on, extracts data from, or attempts credential access against a target:

Ask the user to state the exact target URL, IP, account, or resource.

Ask the user to confirm written authorization and the permitted scope.

Show the exact command(s) and explain their expected effect.

Wait for explicit confirmation in the current conversation.

Without that confirmation, remain read-only and provide defensive guidance only. Prefer a sandbox, disposable VM, or controlled lab.

AUTHORIZED USE ONLY: Use this skill only for authorized security assessments, defensive validation, or controlled educational environments.
