# Performing Dynamic Analysis With Any Run

## Overview

Cybersecurity skill for performing dynamic analysis with any run. Follows industry best practices and security standards.

## When to Use
**Trigger phrases:**
- "performing dynamic analysis with any run"
- "Performs interactive dynamic malware analysis using the ANY"


- Interactive malware analysis is needed where the analyst must click dialogs, enter credentials, or navigate installer screens
- Rapid cloud-based sandbox analysis without maintaining local sandbox infrastructure
- Malware requires user interaction to proceed past anti-sandbox checks (document macros requiring "Enable Content")
- Sharing analysis results with team members via public or private task URLs
- Comparing behavior across different OS versions (Windows 7, 10, 11) available in ANY.RUN

**Do not use** for highly sensitive samples that cannot be uploaded to cloud services; use an on-premises sandbox like Cuckoo instead.


## 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

- ANY.RUN account (free community tier or paid subscription at https://any.run)
- Modern web browser with WebSocket support for interactive session streaming
- Sample file ready for upload (max 100 MB for free tier, 256 MB for paid)
- Understanding of the sample type to select appropriate execution environment
- VPN or secure network for accessing ANY.RUN portal during analysis sessions

## 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 dynamic analysis operations.
2. **Prepare Environment** — Set up tools, access, and data sources required for dynamic analysis.
3. **Execute Core Workflow** — Use any run to perform dynamic analysis 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

- **any run** — Primary tool for this skill
- **Analysis Platform** — Data processing and visualization
- **Collaboration Tools** — Team coordination and knowledge sharing


## Process

1. **Design** — Define interface, identify patterns, plan implementation
1. **Implement** — Write code following existing conventions, add tests
1. **Verify** — Run tests, check integration, validate behavior

## Verification

- [ ] All dynamic analysis 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. |
