You Should Know:
The OSCP (Offensive Security Certified Professional) certification is one of the most challenging and respected certifications in the cybersecurity field. It focuses on hands-on penetration testing skills and requires candidates to pass a rigorous 24-hour exam. Below are some key commands, tools, and steps that are essential for anyone preparing for the OSCP or working in penetration testing:
Essential Tools and Commands:
1. Nmap (Network Mapper)
- Basic scan: `nmap -sV
` - Aggressive scan: `nmap -A
` - UDP scan: `nmap -sU
`
2. Metasploit Framework
- Start Metasploit: `msfconsole`
- Search for exploits: `search
` - Use an exploit: `use exploit/
`
3. Netcat (Swiss Army Knife of Networking)
- Listen on a port: `nc -lvp
` - Connect to a target: `nc
`
4. Directory Enumeration with Gobuster
- Basic directory brute-forcing: `gobuster dir -u http://
-w /path/to/wordlist.txt`
5. Password Cracking with John the Ripper
- Crack a password hash: `john –format=
–wordlist=/path/to/wordlist.txt hashfile.txt`
6. Privilege Escalation on Linux
- Check for SUID binaries: `find / -perm -u=s -o -perm -g=s 2>/dev/null`
- Check for writable files: `find / -writable 2>/dev/null | grep -v “/proc/”`
7. Privilege Escalation on Windows
- Check for unquoted service paths: `wmic service get name,displayname,pathname,startmode | findstr /i “auto”`
- Check for weak permissions: `accesschk.exe -uwcqv “Authenticated Users” * /accepteula`
Steps for OSCP Preparation:
- Build a Home Lab: Use tools like VirtualBox or VMware to create a vulnerable lab environment.
- Practice Enumeration: Master tools like Nmap, Gobuster, and Enum4linux.
- Exploit Vulnerabilities: Practice using Metasploit and manual exploitation techniques.
- Privilege Escalation: Focus on both Linux and Windows privilege escalation methods.
- Document Everything: Keep detailed notes during your practice, as this is crucial for the OSCP exam.
