Communicating with a sensitive source has always been difficult for journalists. Sources who reach out to the media are potentially putting themselves into dangerous situations, breaking contracts, breaking laws, breaking promises and breaking trust.
Meeting in a parking garage at 4 a.m. in trench coats — while still effective in certain circ*mstances — works less in the era of CCTV and mobile phone tracking. When it comes to secure communication, phone calls are out, normal email is laughably awful and SMS is only worse.
Enter: secure messaging apps.
These apps, operating under the same principles as PGP email encryption, are the new frontline in securingcommunications between journalists, sources and contacts.All of these apps offer end-to-end encryption. If thecompany running the servers isever subpoenaed, the only thing they can hand over to prosecutors is essentiallygibberish.
However, the problem with some of these services is that you have to trust that your data is secure, as proprietary companies usually do not open source their software.
I’m going to discuss a few of the pros and cons of several secure messaging apps and offer a few suggestions for which ones journalists should use. Please remember that there is no right answer for everyone. Depending on who you’re hiding from, some apps are more practical or useful than others.

The takeaway
If you’re reporting on the big boys (U.S., Russia, Israel, China), then even these services may not help you. The encryption protecting your messages probably won’t be broken, but the possibilitiesof malware on your device — ora very sophisticated man-in-the-middle attack —are much higher. In thiscase, there are many other internet security issues to be considered as well.
However, if you’re only worried about securing your standard day-to-day communication, I’d recommend Signal. Broadly speaking, if you’re a step below international espionage, iMessage, WhatsApp or Signal all fit the bill.
The biggest key to successfully using any of these tools is normalizing their use. If your team is using Signal, use it for everything.As the adage goes, those on the offensive only have to be lucky once; defenders have to be lucky all the time.

I am Christopher Guess, a computer programmer and photojournalist with extensive expertise in mobile technology and a background in working on media sustainability projects. My knowledge encompasses a wide range of topics related to secure communication tools and their application in journalism. As a professional deeply involved in the intersection of technology and media, I can provide valuable insights into the challenges faced by journalists when communicating with sensitive sources and the solutions offered by secure messaging apps.
The article discusses the evolving landscape of communication between journalists and sources, highlighting the risks associated with traditional methods such as clandestine meetings. It emphasizes the shift towards secure messaging apps as a contemporary solution, drawing parallels to PGP email encryption principles. The focus is on end-to-end encryption, ensuring that even if the servers are subpoenaed, the data remains indecipherable.
