Five quick checks for Linux privilege escalation from a low-privilege shell

The article outlines a short manual routine for finding a path to root on a Linux machine after gaining a standard user shell, aimed at labs and authorized audits. It starts with basic identity and system checks, then focuses on sudo permissions, where allowed binaries can often be abused via GTFOBins-style techniques. It next covers unusual SUID binaries and Linux capabilities, followed by cron jobs and writable scripts run by root. Finally, it suggests searching for credentials in files and history and inspecting services bound only to localhost. The author also promotes a paid cheat-sheet pack alongside free versions.
