# Linux

Once you have a shell on a Linux target, the goal is to understand what you have access to and escalate to root. These pages cover the standard privesc enumeration checklist and common post-exploitation tasks.

    SUID/SGID binaries, sudo misconfigs, cron jobs, writable paths, capabilities, kernel exploits, and enumeration tools (linpeas, pspy)

    Credential hunting, lateral movement prep, persistence, and loot collection after root

## First Things After Shell

Run these immediately on landing to orientate before going deeper:

```bash wrap theme={"theme":{"light":"night-owl","dark":"night-owl"}}
id && whoami                  # current user and groups
hostname && uname -a          # machine name and kernel version
cat /etc/os-release           # distro and version
ip a                          # network interfaces and internal subnets
ss -tlnp                      # listening ports (find internal services)
ps aux                        # running processes (look for interesting daemons)
cat /etc/passwd | grep -v nologin   # valid user accounts
```
