💡 WHAT THIS TEACHES: LINUX PRIVILEGE ESCALATION VECTORS & GTFOBINS

Initial access rarely yields administrative authority. Penetration testers leverage misconfigurations such as SUID binaries (programs that run with the file owner's permissions regardless of caller), Writable Cron Jobs executing as root, and loose sudoers rules (NOPASSWD) documented in the GTFOBins catalog. Securing systems requires enforcing the Principle of Least Privilege, regular auditing with tools like LinPEAS, and removing unnecessary SUID bits.
