OpenClaw Integrates VirusTotal Scanning to Enhance Security

OpenClaw Integrates VirusTotal Scanning to Detect Malicious ClawHub Skills

OpenClaw has announced a partnership with Google-owned VirusTotal to scan skills uploaded to its ClawHub marketplace, aiming to bolster security after reports of malicious plugins and exposed instances. The integration utilizes VirusTotal’s threat intelligence and Code Insight capability to analyze skills and detect potential threats.

Why This Matters

The integration of VirusTotal scanning is crucial in enhancing the security of the OpenClaw ecosystem, as it provides an additional layer of protection against malicious skills that can compromise user data and systems. However, OpenClaw maintainers caution that this is not a foolproof solution, and there is still a risk of cleverly concealed prompt injection payloads evading detection, highlighting the need for continuous security audits and improvements.

Key Insights

• Over 30,000 exposed OpenClaw instances are accessible over the internet, as reported by Censys on February 8, 2026.
• A security analysis of 3,984 skills on the ClawHub marketplace found that 283 skills (about 7.1%) contain critical security flaws, according to a report.
• OpenClaw’s use of plaintext storage for API keys and session tokens, along with ineffective guardrails against indirect prompt injections, poses significant security risks, as noted by HiddenLayer researchers.

Working Example

# Example of how OpenClaw's skill scanning works using VirusTotal's API
import requests

def scan_skill(skill_hash):
    api_key = "YOUR_VIRUSTOTAL_API_KEY"
    url = f"https://www.virustotal.com/api/v3/files/{skill_hash}"
    headers = {
        "Accept": "application/json",
        "x-apikey": api_key
    }
    response = requests.get(url, headers=headers)
    if response.status_code == 200:
        result = response.json()
        if result["data"]["attributes"]["last_analysis_stats"]["malicious"] > 0:
            print("Skill is malicious")
        else:
            print("Skill is benign")
    else:
        print("Error scanning skill")

# Replace "YOUR_SKILL_HASH" with the actual hash of the skill to be scanned
scan_skill("YOUR_SKILL_HASH")

Practical Applications

• Use Case: Companies like Cisco and Bitdefender can utilize OpenClaw’s integration with VirusTotal to enhance their security posture by detecting and preventing malicious skills from compromising their systems.
• Pitfall: A common anti-pattern is the use of overly permissive plugins, which can turn an AI agent into an unintentional automation layer for attackers, as noted by Ensar Seker, CISO at SOCRadar.
