Introduction:
The cybersecurity landscape is facing a critical moment of introspection as three major vendors—Microsoft, SentinelOne, and Palo Alto Networks—withdraw from the 2025 MITRE Engenuity ATT&CK Evaluations. This move challenges the status quo of independent security validation, leaving organizations to question how they can effectively measure and harden their defenses without this key benchmark. The incident forces a re-evaluation of what true security efficacy means in an evolving threat environment.
Learning Objectives:
- Understand the core principles of the MITRE ATT&CK framework and how to use it for threat hunting.
- Learn practical, vendor-agnostic commands and techniques to validate your own endpoint security.
- Develop strategies for independent security control testing beyond commercial evaluation reports.
You Should Know:
1. Mapping Adversaries with MITRE ATT&CK Navigator
The MITRE ATT&CK framework is a knowledge base of adversary tactics and techniques. The ATT&CK Navigator is a web-based tool for visualizing and navigating the framework.
Step-by-step guide:
- Navigate to the MITRE ATT&CK Navigator website: `https://mitre-attack.github.io/attack-navigator/`.
- Click “Create New Layer” and select the “Enterprise” matrix.
- You will see a grid of all tactics (like Initial Access, Execution, Persistence) and techniques. This is your baseline.
- To map a known threat, research its TTPs (Tactics, Techniques, and Procedures). For example, the threat group FIN7 is known for using `Mshta` (T1055.005) for execution and `Windows Management Instrumentation (WMI)` (T1047) for lateral movement.
- In the Navigator, use the search bar to find these techniques. You can then score them (e.g., color-code them) to indicate their relevance to your environment. This creates a customized threat profile for proactive defense.
2. Validating EDR Detection with Atomic Red Team
Atomic Red Team is a library of tests mapped to MITRE ATT&CK that security teams can use to validate their controls. It provides simple commands to simulate adversarial activity.
Verified Commands (Run these in a safe, isolated test environment):
Technique T1059.003 (Windows Command Shell): `cmd.exe /c “whoami”`
Technique T1059.001 (PowerShell): `powershell -Command “Get-Process”`
Technique T1053.005 (Scheduled Task): `schtasks /create /tn “TestTask” /tr “C:\Windows\System32\calc.exe” /sc once /st 00:00`
Technique T1106 (Native API): Use `rundll32.exe` to execute a command: `rundll32.exe kernel32.dll,Sleep,30000`
Step-by-step guide:
- Install Atomic Red Team on a test machine following the guide on its GitHub repository: `https://github.com/redcanaryco/atomic-red-team`.
- Identify a technique you want to test, for example,
T1543.003 (Create or Modify System Process: Windows Service). - Use the Atomic Red Team command to simulate this: `sc.exe create TestService binPath= “C:\Windows\System32\notepad.exe”`
4. Immediately check your EDR/SIEM console. Did an alert trigger? Was the command line logged? This hands-on test provides a ground-truth assessment of your detection capabilities.
3. Open-Source Threat Hunting with Sysmon and Sigma
When vendor evaluations are in question, leveraging open-source tools for visibility becomes paramount. Sysmon (System Monitor) provides detailed logging of system activity, and Sigma is a generic signature language for log events.
Verified Configuration & Commands:
Install Sysmon: Download Sysmon from the Microsoft Sysinternals page. Install it with a popular configuration file like SwiftOnSecurity’s: `Sysmon.exe -i -accepteula -h sha256 -n -l`
Sigma Rule Example (Detecting PsExec):
title: PsExec Service Execution logsource: product: windows service: sysmon detection: selection: EventID: 1 Image|endswith: '\PsExec.exe' CommandLine|contains: ' -s ' condition: selection
Hunting Command with PowerShell: Search for processes spawned by `spoolsv.exe` (a common LOLBin): `Get-WinEvent -FilterHashtable @{LogName=’Microsoft-Windows-Sysmon/Operational’; ID=1} | Where-Object {$_.Properties
.Value -eq "spoolsv.exe"}`
<h2 style="color: yellow;"> Step-by-step guide:</h2>
<ol>
<li>Deploy Sysmon across your endpoints using a Group Policy Object (GPO) or other management tool.</li>
<li>Import a robust set of Sigma rules into your SIEM (if supported) or convert them to your SIEM's native query language.</li>
<li>Regularly run hunts based on the MITRE techniques most relevant to your industry. For example, if you are in finance, hunt for techniques used by FIN7 or Lazarus Group.</li>
</ol>
<h2 style="color: yellow;">4. Hardening Cloud Endpoints with CIS Benchmarks</h2>
With EDR vendors stepping back from evaluations, ensuring a hardened baseline configuration is critical. The Center for Internet Security (CIS) provides consensus-based benchmarks.
<h2 style="color: yellow;"> Verified Commands (Windows Hardening):</h2>
Audit Policy: `auditpol /set /subcategory:"Process Creation" /success:enable /failure:enable`
Disable SMBv1 (a legacy, vulnerable protocol): `Disable-WindowsOptionalFeature -Online -FeatureName SMB1Protocol`
Configure UAC to always notify: `Set-ItemProperty -Path "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System" -Name "ConsentPromptBehaviorAdmin" -Value 2`
PowerShell Logging: Enable Module Logging: `Set-ItemProperty -Path "HKLM:\SOFTWARE\Policies\Microsoft\Windows\PowerShell\ModuleLogging" -Name "EnableModuleLogging" -Value 1`
<h2 style="color: yellow;"> Step-by-step guide:</h2>
<ol>
<li>Download the latest CIS Benchmark for Windows 10/11 or Windows Server from `https://www.cisecurity.org/cis-benchmarks`.</li>
<li>Use the built-in Microsoft Local Group Policy Editor (<code>gpedit.msc</code>) or a security configuration management tool to apply the recommended settings.</li>
<li>Focus on the "Level 1" (basic security) recommendations first. Test these in a non-production environment before rolling them out enterprise-wide to avoid breaking applications.</li>
</ol>
<h2 style="color: yellow;">5. Proactive Defense with YARA for Malware Identification</h2>
YARA is a tool aimed at helping malware researchers identify and classify malware samples. It allows you to create descriptions of malware families based on textual or binary patterns.
<h2 style="color: yellow;"> Verified YARA Rule Example:</h2>
[bash]
rule Detect_Common_Malware_Traits {
meta:
description = "Detects common malware indicators like high entropy and suspicious API calls"
author = "Your Security Team"
date = "2024-09-20"
strings:
$a = {6A 40 68 00 30 00 00 6A 14 8D 91} // Common shellcode pattern
$b = "VirtualAlloc" wide ascii
$c = "CreateRemoteThread" wide ascii
$d = "cmd.exe /c" nocase
condition:
( uint16(0) == 0x5A4D and filesize < 500KB ) and // Is a PE file under 500KB
( 2 of ($b, $c, $d) or $a in (0..500) )
}
Step-by-step guide:
- Install YARA on your analysis machine or security server.
- Write custom rules to hunt for malware specific to your environment or download community-sourced rules from repositories like GitHub.
- Use YARA to scan disk images, memory dumps, or files on the fly. For example: `yara -r rules.yar C:\Users\Public\Downloads\` will recursively scan the Downloads directory.
What Undercode Say:
- The Benchmark is Dead, Long Live the Benchmark. The departure of vendors signals not the end of independent testing, but its evolution. The future lies in continuous, transparent, and open-source-led validation methods that organizations can run themselves.
- Take Back Control. This event is a wake-up call for security teams to reduce reliance on vendor marketing and build in-house expertise for validating security controls through continuous testing and threat hunting.
The MITRE Evaluations served as a crucial, albeit imperfect, common yardstick. Their decline in participation forces the industry to mature. The focus must shift from buying a “top-rated” product to building a resilient security posture grounded in continuous validation. This means investing in skills, embracing open-source intelligence and tools, and demanding greater transparency from vendors. The era of trusting a single score is over; the era of verifiable, evidence-based security is beginning.
Prediction:
The void left by the departure of major vendors from centralized evaluations will accelerate three key trends. First, we will see the rise of consortium-based testing, where large enterprises and MSSPs pool resources to fund independent, real-world tests. Second, regulatory bodies will increasingly step in, potentially mandating specific, standardized security testing for critical infrastructure vendors, similar to the Common Criteria scheme. Finally, the demand for internal security validation skills will skyrocket, making the ability to conduct red team exercises and control assessments a core competency for any serious security program, ultimately leading to a more resilient and self-reliant cybersecurity ecosystem.
