virustotal security scanner

What This Skill Does

The VirusTotal security scanner is a powerful integration for OpenClaw that allows you to interface directly with the VirusTotal API. This skill enables the verification of files and URLs against one of the world's largest crowdsourced threat intelligence databases. By utilizing either standard curl commands or Python scripts, the agent can perform hash lookups, request detailed file reports, or upload suspicious artifacts for analysis. It is an essential tool for security researchers and developers who need to validate the integrity of downloaded binaries or investigate potential indicators of compromise within their local environments.

Installation

To install this skill, run the following command in your terminal: clawhub install openclaw/skills/skills/aleph8/virustotal

Once installed, obtain your API key from your VirusTotal profile settings and configure it in your environment variables: export VT_API_KEY="your-api-key-here" Ensure you have curl installed on your system, as it is the default tool used for API requests.

Use Cases

• Malware Analysis: Quickly check if an unknown executable hash matches known malicious files in the VirusTotal database.
• URL Safety: Validate the reputation of suspicious links or domains encountered in logs or emails before navigating to them.
• Automated Incident Response: Use the skill to automatically hash local files and cross-reference them with threat intelligence during an automated security sweep.
• Efficient Caching: Implement local caching of reports in ~/.vt/ to minimize API usage and speed up repeated lookups of the same files.

Example Prompts

• "Can you check the VirusTotal reputation for the file located at /downloads/installer.exe?"
• "I found a suspicious hash 'e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855'; can you pull the full analysis report for me?"
• "Upload this binary to VirusTotal for community analysis, but please remind me about the privacy policy first."

Tips & Limitations

• Privacy Warning: Always remember that VirusTotal is a public service. Data uploaded to their servers is shared with the global security community. Never upload sensitive, proprietary, or private user data.
• File Size: Uploads for standard endpoints are restricted to 32MB; for larger files, utilize the VirusTotal intelligence API upload URLs.
• Caching: Always cache your results. Repeatedly querying the same hash will hit your daily API rate limits quickly. Use the suggested ~/.vt directory structure to optimize your workflow and improve agent response times.
