Jihadi Tech Group Offers Tutorial On Using Secure Messaging App Threema

March 9, 2016

On March 8, 2016, the Electronic Horizon Foundation (EHF), a crowdsourcing group that offers tech-related information for jihadis, published a lengthy tutorial on installing and using the secure messaging app Threema.

Threema, developed by the Swiss company Threema GmbH, provides encrypted instant messaging on Android and iOS devices.

The tutorial, posted on Justpaste.it and circulated on the EHF’s Telegram channel, offers some background information about the app, and provides steps to install the app and manage its various functions.

It notes the advantages of using Threema – for example, it says that it allows anonymous use without the need to provide a phone number or an email address, that communication using it is end-to-end encrypted, and that the secret key (used for encryption and decryption) is stored on the user’s phone, not the company’s servers. This, it says, “prevents the company from decrypting the messages in the case it was pressured [to do so] by government bodies.”

The post also plays up the fact that the company’s servers are located in Switzerland, which is says “is among the best in protecting the privacy of Internet users.”
