Secure Messaging: The Guardian Leverages Millions of Readers to Provide Strong Plausible Deniability

The Guardian has introduced a tool called Secure Messaging to protect journalistic sources, utilizing an open-source technology named CoverDrop. This system allows whistleblowers to communicate securely and anonymously with journalists by concealing the fact that messaging is occurring. CoverDrop integrates a module within The Guardian's mobile app, an untrusted cloud-based API, on-premises services known as CoverNode, and a desktop application for journalists. The CoverNode functions as a mix node to ensure the anonymity of sources. The app exchanges encrypted messages that appear indistinguishable from regular app data, providing cover for users. The technology has been rolled out to millions of users this year, and a white paper detailing its design has been published. Currently, the platform does not allow sharing of photographs or documents, but future plans include linking uploaded files with conversations. The source code for CoverDrop is available on GitHub under the Apache License 2.0.

Jack Dorsey launches Bitchat, a secure messaging app that doesn’t use the internet

Jack Dorsey, co-founder of Twitter, Bluesky, and Square, has introduced a private messaging application called Bitchat, which operates independently of traditional internet or cellular networks. Bitchat utilizes decentralized Bluetooth technology and end-to-end encryption for secure communication. It is based on Bluetooth Low Energy (BLE) mesh networks, extending the typical Bluetooth range from 100 meters to 300 meters. Developed with the help of an AI coding companion named Goose, Bitchat is described as a "weekend project." The app aims to provide resilient and private communication, but critics have raised security concerns about its authentication system. Dorsey has issued a disclaimer stating that Bitchat is a "work in progress" and has not undergone external security review, warning users against relying on its security until it is evaluated.
