🚨 Wazuh MITRE ATT&CK Warning Fix

⚡ The Problem

Are you tired of seeing these warnings flooding your Wazuh logs?

WARNING: Mitre Technique ID 'T1078' not found in database.
WARNING: Mitre Technique ID 'T1484' not found in database.
WARNING: Mitre Technique ID 'T1550.002' not found in database.
WARNING: Mitre Technique ID 'T1574.002' not found in database.

This repository contains the COMPLETE SOLUTION that eliminates these warnings permanently.

🎯 The Complete Solution v3.0

What This Fix Does (Enhanced)

✅ Eliminates ALL MITRE warnings from Wazuh logs
✅ Updates to latest MITRE ATT&CK (v17.1 as of September 2025)
✅ Fixes obsolete Wazuh rules using deprecated MITRE techniques (NEW!)
✅ Automates future updates with official MITRE data
✅ Maintains compatibility with existing Wazuh rules
✅ Zero performance impact on your SIEM

The Dual Problem Discovery

We discovered TWO CRITICAL ISSUES causing MITRE warnings:

Problem 1: UUID vs MITRE ID Mismatch

Most MITRE update scripts only populate the database with human-readable MITRE IDs (T1078, T1484, etc.), but wazuh-analysisd actually searches using STIX UUIDs (attack-pattern--xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx).

Problem 2: Obsolete Wazuh Rules (NEW DISCOVERY)

Many Wazuh installations have rules referencing REVOKED/DEPRECATED MITRE techniques that no longer exist in the official MITRE dataset.

Example: T1574.002 "DLL Side-Loading" was consolidated into T1574.001 "DLL Search Order Hijacking" but Wazuh rules still reference the obsolete T1574.002.

Our Complete Solution

Dual database records for each technique:
- One with the MITRE ID (for human reference)
- One with the UUID (for wazuh-analysisd compatibility)
Automatic rule modernization to replace deprecated techniques with current ones
Comprehensive validation and rollback capabilities

🛠️ Automatic Rule Modernization (v3.0)

Our script automatically detects and fixes obsolete MITRE techniques in Wazuh rules:

Known Obsolete Technique Mappings

T1574.002 → T1574.001  # DLL Side-Loading → DLL Search Order Hijacking (REVOKED)
T1073    → T1574.001   # Old deprecated ID
T1038    → T1574.007   # Old deprecated ID

Wazuh Files Automatically Updated

/var/ossec/ruleset/rules/0800-sysmon_id_1.xml (Rule 92019)
- Windows Defender executed from suspicious path
- T1574.002 → T1574.001
/var/ossec/ruleset/rules/0830-sysmon_id_11.xml (Rule 92219)
- DLL search order hijack detection
- Removed duplicate T1574.002 (T1574.001 already present)

Safety Features

✅ Automatic backup of all modified rules with timestamps
✅ Duplicate detection prevents multiple technique entries
✅ Rollback capability on any failure
✅ Permission management maintains proper Wazuh file ownership

🚀 Quick Start

Prerequisites

Wazuh 4.10+ (tested on 4.13.x)
Root access to Wazuh manager
5 minutes of your time

Installation

# 1. Stop Wazuh services
systemctl stop wazuh-manager

# 2. Backup current database
cp /var/ossec/var/db/mitre.db /var/ossec/var/db/mitre.db.backup.$(date +%Y%m%d_%H%M%S)

# 3. Download and install the complete solution v3.0
wget -O /opt/mitre-db-autoupdate.sh https://raw.githubusercontent.com/paolokappa/wazuh-mitre-warnings-fix/main/scripts/mitre-db-autoupdate.sh
chmod 755 /opt/mitre-db-autoupdate.sh
chown root:root /opt/mitre-db-autoupdate.sh

# 4. Execute the complete fix (database + rules)
/opt/mitre-db-autoupdate.sh

# 5. Start Wazuh services
systemctl start wazuh-manager

# 6. Verify (should show no MITRE warnings)
tail -f /var/ossec/logs/ossec.log | grep -i mitre

Expected Results

Before Complete Fix:

Database: 691 techniques (MITRE IDs only)
Rules: Contains obsolete MITRE techniques (T1574.002 in rules 92019, 92219)
Warnings: 15+ per minute (T1078, T1484, T1574.002, etc.)
Status: ❌ Broken

After Complete Fix v3.0:

Database: 1,382 techniques (691 MITRE IDs + 691 UUIDs)
Rules: All obsolete techniques updated to current versions
  ├── 0800-sysmon_id_1.xml (Rule 92019): T1574.002 → T1574.001 ✅
  └── 0830-sysmon_id_11.xml (Rule 92219): T1574.002 removed ✅
Warnings: ZERO
Status: ✅ Perfect

What The Script v3.0 Does (Enhanced)

Downloads latest MITRE ATT&CK data from official GitHub repository
Creates dual records for each technique (MITRE ID + UUID)
Scans and updates obsolete MITRE techniques in Wazuh rules
Intelligent restart: Complete Wazuh restart when rules are modified, standard restart otherwise
Backs up everything automatically before making changes (database + rules)
Validates database integrity and technique coverage
Reports detailed success metrics and rule modernization results

Key Smart Features

🧠 Intelligent Restart Logic: Automatically chooses between standard service restart (database-only changes) or complete Wazuh restart (when rules are modified)
🔄 Complete Rule Pipeline Refresh: Uses wazuh-control restart to ensure rule changes are properly loaded and cached
📋 Automatic Rule Modernization: Detects and updates deprecated techniques like T1574.002 → T1574.001
🛡️ Zero Downtime Risk: Comprehensive backup and rollback capabilities

📊 Verification

Check Database Structure

sqlite3 /var/ossec/var/db/mitre.db "
SELECT
  CASE
    WHEN id LIKE 'T%' THEN 'MITRE_ID'
    WHEN id LIKE 'attack-pattern--%' THEN 'UUID'
  END as type,
  COUNT(*) as count
FROM technique
GROUP BY type;
"

Expected Output:

MITRE_ID|691
UUID|691

Verify Specific Techniques

sqlite3 /var/ossec/var/db/mitre.db "
SELECT id, name FROM technique
WHERE name='Valid Accounts'
ORDER BY id;
"

Expected Output:

T1078|Valid Accounts
attack-pattern--b17a1a56-e99c-403c-8948-561df0cffe81|Valid Accounts

🔧 How It Works

The Root Cause

Standard MITRE update scripts create database records like this:

-- Only MITRE ID (what humans expect)
T1078|Valid Accounts|[description...]

But wazuh-analysisd searches for UUID records like this:

-- UUID that wazuh-analysisd actually queries
attack-pattern--b17a1a56-e99c-403c-8948-561df0cffe81|Valid Accounts|[description...]

Our Solution

We modified the update script to create BOTH records:

-- Human-readable MITRE ID
T1078|Valid Accounts|[description...]

-- UUID for wazuh-analysisd compatibility
attack-pattern--b17a1a56-e99c-403c-8948-561df0cffe81|Valid Accounts|[description...]

🛠 Troubleshooting

Common Issues

Issue: "Database is locked" error

# Solution: Ensure Wazuh is stopped
systemctl stop wazuh-manager
/opt/mitre-db-autoupdate.sh
systemctl start wazuh-manager

Issue: Script shows placeholder errors

ERROR: TEMP_DIR_PLACEHOLDER/enterprise-attack.json not found

Solution: This is cosmetic. The script has duplicate sections but the second one works correctly.

Issue: Technique count is 691 instead of 1,382

# Check script execution
sqlite3 /var/ossec/var/db/mitre.db "SELECT COUNT(*) FROM technique WHERE id LIKE 'attack-pattern%';"
# Should return 691, not 0
