Operation Contraband – Secure File Sharing and Communication via OnionShare

In the heart of a bustling metropolis, an undercover investigator prepares for a crucial phase of Operation Contraband. The goal: to securely share sensitive files related to an ongoing investigation into illegal activities on the dark web and establish a covert communication channel with international law enforcement partners. Given the sensitivity of the information and the need for utmost secrecy, the investigator turns to OnionShare.

Mission Setup

The investigator organizes all critical data into a meticulously structured folder: “Cases/Case001/Export/DarkWeb/OnionShare/”. This folder contains various types of evidence including documents, intercepted communications, and detailed reports—all vital for building a strong case against the suspects involved.

Deploying OnionShare

The investigator boots up their system and prepares OnionShare to transmit this crucial data. With a few commands, they initiate the process that will allow them to share files securely and anonymously, without risking exposure or interception.

Operational Steps
    1. Launch OnionShare: The tool is activated from a command line interface, a secure gateway devoid of prying eyes. Each keystroke brings the investigator closer to achieving secure communication.

    2. Share Files: The investigator inputs the following command to share the contents of the “Cases/Case001/Export/DarkWeb/OnionShare/” directory. This command sets the operation to share mode, ensuring that every piece of evidence is queued for secure delivery:

      onionshare-cli --title "Contraband" --public /path/to/Cases/Case001/Export/DarkWeb/OnionShare/
    3. Establish Chat Server: Simultaneously, the investigator opts to start a chat server using the following command. This chat server will serve as a secure communication line where operatives can discuss details of the operation in real-time, safe from external surveillance or interception:

      onionshare-cli --chat --title "Contraband" --public
    4. Set Title and Access: The chat server is titled “Contraband” to discreetly hint at the nature of the operation without revealing too much information. By using the --public option, the investigator ensures that the server does not require a private key for access, simplifying the process for trusted law enforcement partners to connect. However, this decision is weighed carefully, as it slightly lowers security in favor of easier access for those who possess the .onion URL.

    5. Distribute .onion URLs: Upon activation, OnionShare generates unique .onion addresses for both the file-sharing portal and the chat server. These URLs are Tor-based, anonymous web addresses that can only be accessed through the Tor browser, ensuring that both the identity of the uploader and the downloader remain concealed.


With the infrastructure set up, the investigator sends out the .onion addresses to a select group of trusted contacts within the international law enforcement community. These contacts, equipped with the Tor browser, use the URLs to access the shared files and enter the encrypted chat server named “Contraband.”


The operation unfolds smoothly. Files are downloaded securely by authorized personnel across the globe, and strategic communications about the case flow freely and securely through the chat server. By leveraging OnionShare, the investigator not only ensures the integrity and confidentiality of the operation but also facilitates a coordinated international response to combat the activities uncovered during the investigation.

Operation Contraband exemplifies how OnionShare can be a powerful tool in law enforcement and investigative operations, providing a secure means to share information and communicate without risking exposure or compromising the mission. As the digital landscape continues to evolve, tools like OnionShare remain critical in ensuring that sensitive communications remain shielded from adversarial eyes.
