Source Guide

Choose who to submit to

Each SecureDrop instance is totally independent, and submissions to that instance are only available to journalists associated with that organization.

All organizations have a landing page that provides their own organization-specific recommendations for using SecureDrop. We encourage you to consider an organization’s landing page before submitting to them.

Most organizations make their landing page prominently accessible from their main website’s homepage. You can also find an incomplete list of organizations accepting submissions through SecureDrop on the SecureDrop Directory maintained by Freedom of the Press Foundation.

Get the Tor Browser

Each SecureDrop instance has a publicly available Source Interface: a website where sources can create anonymous accounts, submit files and messages, and check back for replies.

Each Source Interface is only available as a Tor Hidden Service, which is a special type of website with an address ending in ”.onion” that is only accessible through Tor. Tor is an anonymizing network that makes it difficult for anybody observing the network to associate a user’s identity (e.g. their computer’s IP address) with their activity (e.g. uploading information to SecureDrop).

The easiest and most secure way to use Tor is to download the Tor Browser Bundle from the Tor Project website. This bundle includes the Tor Browser, a modified version of the Firefox web browser designed to protect your security and anonymity while using Tor.

Once you have the Tor Browser, launch it and enter the ”.onion” address for the Source Interface of the organization that you wish to submit to. You can find this address on the organization’s landing page, or listed on the SecureDrop Directory.

While using the Tor Browser on your personal computer helps hide your activity on the network, it leaves traces (of its own installation) on your local machine. For even more deniability, we recommend booting into a live system such as Tails for a higher level of security. Tails is specifically designed to run on your computer without leaving traces of your activity, and automatically routes all of your Internet browsing through Tor so you can easily access SecureDrop safely.

Making your First Submission

Open the Tor Browser and navigate to the .onion address for the SecureDrop Source Interface you wish to make a submission to. The page should look similar to the screenshot below, although it will probably have a logo specific to the organization you are submitting to.

If this is the first time you’re using the Tor browser, it’s likely that you have Javascript enabled and that the Security Slider that Tor browser provides is set to “Low”. If you do, there will be a purple warning banner at the top of the page that encourages you to disable Javascript and turn up the Security Slider to “High”.

Click the Learn how to set it to high link in the warning banner and a message bubble will pop up explaining how to disable Javascript and turn up the Slider. Follow the instructions and the page should refresh automatically. Note that this will change the slider and disable Javascript for every page in your Tor Browser, and this setting will persist across browser sessions.

The page should now look similar to the screenshot below. If this is the first time you are using SecureDrop, click the Submit Documents button.

You should now see a screen that shows the unique codename that SecureDrop has generated for you. In the example screenshot below the codename is catering zit isotope consonant tiny shriek provider, but yours will be different. It is extremely important that you both remember this code and keep it secret. After submitting documents, you will need to provide this code to log back in and check for responses.

The best way to protect your codename is to memorize it. If you cannot memorize it right away, we recommend writing it down and keeping it in a safe place at first, and gradually working to memorize it over time. Once you have memorized it, you should destroy the written copy.

Once you have generated a codename and put it somewhere safe, click Continue.

You will next be brought to the submission interface, where you may upload a document, enter a message to send to journalists, or both. You can only submit one document at a time, so you may want to combine several files into a zip archive if necessary. The maximum submission size is currently 500MB. If the files you wish to upload are over that limit, we recommend that you send a message to the journalist explaining this, so that they can set up another method for transferring the documents.

When your submission is ready, click Submit.

After clicking Submit, a confirmation page should appear, showing that your message and/or documents have been sent successfully. On this page you can make another submission or view responses to your previous messages.

Once you are finished submitting documents, be certain you have saved your secret codename and then click the Exit button:

The final step to clearing your session is to restart Tor Browser for optimal security. You can either close the browser entirely or follow the notification: click on the Tor onion in the toolbar, click New Identity and then click Yes in the dialog box that appears to confirm you’d like to restart Tor Browser:

Continuing the Conversation

If you have already submitted a document and would like to check for responses, click the Check for a Response button on the media organization’s SecureDrop homepage.

The next page will ask for your secret codename. Enter it and click Continue.

If a journalist has responded, their message will appear on the next page. This page also allows you to upload another document or send another message to the journalist. Before leaving the page, you should delete any replies. In the unlikely event that someone learns your codename, this will keep your identity secret as no one will be able to see the previous correspondences you had with journalists.

After you delete the message from the journalist, make sure you see the below message.

If the server experiences a large number of new sources signing up at once and is overloaded with submissions, the journalist will flag your message on their end and you will see the message below. They can’t write a reply to you until you’ve seen this message for security reasons. This will only happen the first time a journalist replies and with subsequent replies you will skip this step. Click Refresh or log in again to see if a journalist has responded.

Repeat these steps to continue communicating with the journalist.
