OpenClaw Security Checklist: 5 Things to Do Before Every Session

Why Your OpenClaw Setup is a Target

OpenClaw is a powerful, open-source platform that puts cutting-edge AI at your fingertips. But with great power comes great responsibility. As the community has discovered, a misconfigured OpenClaw instance can be a wide-open door for attackers. The conversation is happening everywhere, from Reddit to X.

"OpenClaw's biggest security risk isn't malicious skills. It's your config." - r/OpenClaw user

While the threat of malicious community 'Skills' is real, the most common and devastating vulnerabilities often stem from basic setup mistakes. Users are right to be concerned, asking questions like:

"Has anyone actually had a security issue with open claw?" - Don't get me wrong I can definitely imagine everything from prompt injection to people accessing you[r] [files].

The answer is a resounding 'yes'. From stolen credentials to full system takeovers, the risks are significant. This checklist will walk you through the five most critical areas you need to lock down right now. For a deeper look at the threats themselves, see our companion article on OpenClaw security risks.

1. Stop Hardcoding API Keys: Use Environment Variables

Your API keys for services like OpenAI, Anthropic, or Google are the literal keys to your kingdom. Hardcoding them directly into config.yaml or other files is like leaving your house key under the doormat. If your code is ever exposed, or if a malicious skill gains file system access, your keys will be stolen. This can lead to massive bills and data breaches.

The Fix: Use environment variables. Store your keys in a .env file and ensure that file is listed in your .gitignore to prevent it from ever being committed to a repository. Load them into your application's environment at runtime. Our API key management guide covers best practices for handling provider credentials.

• Never commit files containing secrets to Git.
• Rotate your API keys regularly (e.g., every 90 days) and immediately if you suspect a leak.
• Consider using a dedicated secret manager like HashiCorp Vault or AWS Secrets Manager for production setups.

2. Enforce Least Privilege: Lock Down File System Permissions

OpenClaw, by its nature, needs to read and write files. But it should never have more access than it absolutely needs. Running OpenClaw as the root user is a catastrophic mistake. A single vulnerability could allow an attacker to take over the entire machine. Even the OpenClaw team is constantly working to fix these kinds of bugs, as shown in their own updates:

Path traversal and Local File Inclusion (LFI) vulnerabilities allow attackers to read sensitive files outside of the intended directory, like /etc/passwd or your SSH keys. Running as a non-root user in a restricted directory is your best defense.

The Fix:

1. Create a dedicated, non-root user specifically for running the OpenClaw service.
2. Run OpenClaw from a directory owned by that user.
3. Set file permissions to be as restrictive as possible (e.g., chmod 600 for sensitive config files).
4. Consider running OpenClaw inside a container (like Docker) for an additional layer of isolation.

3. Minimize Your Attack Surface: Network Exposure & Firewalls

How you expose OpenClaw to the network is one of the most critical security decisions you'll make. Running it on your primary work or personal computer is a recipe for disaster. The community strongly advises against this:

10 things to lock it down:

1. Run it on a VPS or Mac mini, not your main machine
2. Never run a[n open port]

Isolating the process on a dedicated machine is the standard for a reason. Whether it's a cheap cloud server or a secondary computer at home, isolation prevents a compromise from affecting your primary data.

One of my best engineers just showed me how to set up OpenClaw securely & without a Mac Mini.

Here's his step-by-step:

1) Spin up a VPS on Hetzner
— @businessbarista on X

The Fix:

• Run OpenClaw on a dedicated Virtual Private Server (VPS) or a secondary machine.
• Use a firewall (like ufw on Linux) to block all incoming ports except those you absolutely need (e.g., SSH on a non-standard port and the application port).
• If you need to access it remotely, use a VPN or an SSH tunnel instead of exposing the web interface directly to the public internet.

4. Defend Against Prompt Injection & Malicious Skills

The AI-specific threat you can't ignore is prompt injection. This is an attack where a user inputs a malicious prompt designed to bypass or override the AI's original instructions. This can be used to leak the system's base prompt, exfiltrate data from the context window, or trigger unintended actions. This risk is amplified by the OpenClaw 'Skills' ecosystem, which has unfortunately been a vector for malware.

This real-world incident shows how a seemingly useful 'Skill' can be a trojan horse. While this specific attack targeted the host system, skills can also be designed to facilitate complex prompt injection attacks.

The Fix:

• Vet Community Skills: Only install skills from trusted authors. Review the source code before installing.
• Input Sanitization: Implement filtering for user inputs to block instruction-like phrases or keywords.
• Instructional Fences: Clearly demarcate instructions from user input in your prompts (e.g., using XML tags like <user_input>).
• Output Parsing: Validate the AI's output to ensure it conforms to the expected format and doesn't contain malicious code or leaked data.

5. Know When You're Under Attack: Implement Audit Logging

If a breach occurs, your first question will be, "What happened?" Without logs, you'll have no answer. Comprehensive logging is not a preventative measure, but it's essential for detection, response, and forensics. You need to log key events like:

• User authentications (successes and failures)
• API calls made by the AI
• Skills being installed or executed
• Critical errors and exceptions
• Changes to configuration

The Fix:

Enable OpenClaw's built-in logging and ensure it's configured to be verbose. For serious deployments, forward these logs to a centralized logging platform (like an ELK stack, Graylog, or a cloud-based SIEM) where they can be stored securely, searched, and monitored for suspicious activity. Set up alerts for high-risk events like multiple failed logins or the execution of a new, untrusted skill.
