Day 16: The Linux Auditor’s Roadmap — Post-Exploitation Mastery 🕵️‍♂️

🛠️ The Security Auditor’s Recap

My journey through the Linux "Fortress" has taught me that most system compromises aren't caused by complex exploits, but by simple, preventable configuration errors.

1. The Stability Protocol

Getting a shell is just step one. Turning a "dumb shell" into an interactive session (TTY) is where professional work begins:

python3 -c 'import pty; pty.spawn("/bin/bash")'
Ctrl + Z
stty raw -echo; fg
export TERM=xterm

2. The Privilege Escalation Audit Checklist

When I land on a system, my "Mental Scanner" now looks for:

Sudo Rights (sudo -l): Are there binaries I can run as root without a password? (GTFOBins is my best friend here).
SUID Binaries (find / -perm -4000): Are there files that execute with root's authority?
Cron Jobs (/etc/crontab): Is there a script I can write to that runs as root?
PATH & Wildcards: Does the system rely on sloppy path execution or wildcard-based commands?
