Linux Privilege Escalation — From Enumeration to Root

New Resource: Linux Privilege Escalation — From Enumeration to Root (Free PDF)

I came across a highly practical Linux Privilege Escalation guide, and it’s one of the most complete references for learning how attackers escalate from a low-privilege shell to full system control — purely for ethical, defensive, and lab-based practice.

Whether you’re in Red Teaming, Pentesting, Blue Team defense, or preparing for certification labs, this walkthrough breaks down real-world paths used in post-exploitation.

What the Guide Covers (High-Level & Educational)

Enumeration (Manual & Automated)

Understanding the system: kernel version, users, permissions, scheduled tasks, SUID/SGID binaries, services, and more — plus tools like LinEnum, LinPEAS, and enumy.

Shells & Restricted Environments

Stabilizing shells, escaping limited environments, and understanding how legitimate binaries can be misused if misconfigured (GTFOBins concepts).

Privilege Escalation Concepts

Kernel & sudo misconfigurations

Weak file permissions

Credential exposure in logs/backups

Container misconfigurations (Docker/LXD)

Service and environment misconfigurations

Binary & Environment Abuse

How PATH issues, SUID binaries, shared objects, and cron/systemd misconfigurations create escalation opportunities.

Network & File Share Weaknesses

NFS misconfigs, exposed local services, and other common enterprise mistakes.

Session Handling

High-level awareness of screen/tmux session control and defensive monitoring.
