# Performing Malware Persistence Investigation

## Overview

Cybersecurity skill for performing malware persistence investigation. Follows industry best practices and security standards.

## When to Use
**Trigger phrases:**
- "performing malware persistence investigation"
- "Systematically investigate all persistence mechanisms on Windows and Linux syste"

- 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


## When NOT to Use

- When you lack proper authorization for testing
- For production systems without change management
- When the task requires legal or compliance expertise beyond technical scope


## 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

```python
# Example: IOC detection
import re

IOC_PATTERNS = {
    "ip": r"\b(?:\d{1,3}\.){3}\d{1,3}\b",
    "domain": r"\b[a-z0-9-]+\.[a-z]{2,}\b",
    "hash_md5": r"\b[a-f0-9]{32}\b",
    "hash_sha256": r"\b[a-f0-9]{64}\b",
}

def extract_iocs(text: str) -> dict:
    return {k: re.findall(v, text) for k, v in IOC_PATTERNS.items()}
```

1. **Plan Operations** — Define objectives, scope, and success criteria for malware persistence investigation operations.
2. **Prepare Environment** — Set up tools, access, and data sources required for malware persistence investigation.
3. **Execute Core Workflow** — Perform the malware persistence investigation operations following established procedures.
4. **Validate Results** — Verify that results meet quality standards and objectives.
5. **Report Findings** — Document results, observations, and recommendations.
6. **Follow Up** — Track remediation actions and verify fixes where applicable.

## Tools

- **Analysis Platform** — Data processing and visualization
- **Collaboration Tools** — Team coordination and knowledge sharing


## Process

1. **Reconnaissance** — Gather target information, identify attack surface, enumerate services
1. **Analysis/Exploitation** — Execute the technique, analyze results, document findings
1. **Reporting** — Document IOCs, write findings, provide remediation recommendations

## Verification

- [ ] All malware persistence investigation procedures executed completely and documented
- [ ] Findings validated against multiple data sources
- [ ] False positives identified and filtered
- [ ] Results documented with evidence and timestamps
- [ ] Recommendations provided with risk-based prioritization

## Anti-Rationalization Table

| Rationalization | Reality |
|---|---|
| "We are too small to be targeted" | Automated attacks target everyone. Size does not matter. |
| "Security slows us down" | A breach slows you down 100x more. Build security in from the start. |
| "We will fix it after launch" | Vulnerabilities in production are exploited within hours. Fix before deploy. |
