Performing Malware Persistence Investigation

When to Use

• When investigating how malware maintains presence on a compromised system after reboots
• During incident response to identify all persistence mechanisms for complete remediation
• For threat hunting to discover unauthorized autostart entries across endpoints
• When analyzing malware behavior to understand its persistence strategy
• For verifying that all persistence has been removed after incident remediation

Prerequisites

• Forensic image or live system access with administrative privileges
• Autoruns (Sysinternals) for Windows persistence enumeration
• RegRipper for offline registry analysis
• Understanding of Windows and Linux persistence mechanisms
• YARA rules for scanning persistence locations
• Baseline of known-good autorun entries for comparison

Workflow

Step 1: Enumerate Windows Registry Persistence

# Extract registry hives from forensic image
mount -o ro,loop,offset=$((2048*512)) /cases/case-2024-001/images/evidence.dd /mnt/evidence

# Key registry persistence locations
python3 << 'PYEOF'
from Registry import Registry
import json

results = {'registry_persistence': []}

# SYSTEM hive …
