Key OPSEC Guidelines

1. Use the Tor Browser: Access dark web resources exclusively through the Tor Browser. This ensures that your traffic is routed through layered encrypted relays, significantly reducing the risk of surveillance (1).

2. Verify .onion Addresses: Always confirm the exact 56-character .onion addresses before accessing them. Phishing attempts often involve slight variations of legitimate addresses, aiming to harvest credentials (1), (1).

3. Avoid Clearnet Tools: Do not rely on clearnet search engines for accessing .onion sites. Tools like DuckDuckGo's .onion mirror do not function as dark web search engines and may expose you to unfiltered content (9).

4. Limit Script Execution: Disable script execution within the Tor Browser. This precaution minimizes the risk of executing malicious scripts that could compromise your system.

5. Monitor Exit Nodes: Be aware that exit nodes can be malicious. They can intercept unencrypted traffic leaving the Tor network. Always use HTTPS on sites accessed through Tor to encrypt your data.

Risks to Consider

• Malicious Exit Nodes: Attackers may set up exit nodes to capture traffic. Always ensure sensitive data remains encrypted to prevent exposure.

• Script Execution Vulnerabilities: Executing scripts can lead to unintentional data leaks or malware installation. Keep scripts disabled to safeguard against these risks.

• Protocol Leaks: Check for IP address leaks via WebRTC or other protocols. Tools and settings within the Tor Browser can help prevent these leaks.
