Centre bans Bitchat app used during internet curbs; cites security risks

The Indian government has instructed GitHub to remove the Bluetooth-based messaging application Bitchat due to concerns about its potential misuse for anti-national activities, including terrorism and cybercrime. The directive was issued by the Indian Cyber Crime Coordination Centre (I4C), which noted that Bitchat's decentralized communication through Bluetooth mesh networks hinders lawful interception and investigations by law enforcement agencies.

Govt orders GitHub to remove code for internet-free messaging app

The Indian Cyber Crime Coordination Centre (I4C) has directed GitHub to remove three repositories associated with the Bitchat messaging application, co-founded by Jack Dorsey. This action is one of the first implementations of the amended IT Rules' "reasoned intimation" mechanism, extending the takedown framework to software repositories. I4C expressed concerns about Bitchat's potential misuse for unlawful activities such as coordinating unlawful assemblies, inciting violent protests, disseminating misinformation, radicalization, and criminal conspiracies. The application allows for anonymous communication without user registration or centralized logging, complicating law enforcement's ability to conduct lawful interception and investigations.

GitHub ordered to remove decentralized messaging app Bitchat in India

India's Ministry of Home Affairs has ordered GitHub to remove repositories related to Jack Dorsey's Bitchat application, citing concerns that the platform could allow users to bypass internet shutdowns and evade surveillance.

The repositories in question are: - github.com/permissionlesstech/bitchat - github.com/permissionlesstech/bitchat-android - github.com/permissionlesstech/bitchat-android/releases Bitchat is a decentralized messaging app that operates over Bluetooth mesh networks, which does not require internet access and facilitates anonymous communication.

The order comes amid ongoing protests in New Delhi, where internet access has been suspended. The Internet Freedom Foundation has criticized the order as unconstitutional and has called for its retraction. It is currently unclear if GitHub will comply with the takedown request.

What You Should Know About Jack Dorsey’s New Messaging App Bitchat

Jack Dorsey launched an open-source messaging app called Bitchat Mesh, or Bitchat, on July 28 through Apple's App Store. The app utilizes Bluetooth for data transmission instead of traditional internet connections and does not use contacts or phone numbers for connectivity, instead forming a Bluetooth mesh network among nearby devices. Each device acts as both a client and server, allowing for communication within the network, which is limited to those in proximity. Users can see the number of connected devices and send private messages, while main chat messages are visible to all within the network. Bitchat includes features like blocking users and sending playful notifications. Despite being open-source, the app has not undergone a third-party security audit, and users have been cautioned about potential vulnerabilities. Dorsey implemented the Noise Protocol Framework for end-to-end encryption but advised against using the app for production purposes until it receives an external security review.

Twitter Co-Founder Jack Dorsey’s Bitchat Aims to Kickstart the Offline Messaging Revolution

Jack Dorsey is developing Bitchat, a decentralized messaging application created over a weekend. It operates on Bluetooth Low Energy (BLE) mesh networks, allowing devices within a 300-meter range to exchange encrypted messages without the need for internet connectivity or phone numbers. Bitchat forms a dynamic mesh network where messages can hop through nearby devices if a direct connection is unavailable. Messages are end-to-end encrypted, stored only on the sender's and receiver's devices, and disappear after a set time. Users can create group discussions, called "rooms," with hashtags and passwords, and a "Panic Mode" feature enables quick data deletion. Bitchat includes store-and-forward messaging for offline users and has plans for a Wi-Fi Direct update. The app does not collect personal information or track user activity, making it suitable for use in regions with censorship or network issues. Its beta launch on TestFlight quickly reached 10,000 users, and it features a minimalist interface for ease of use. The open-source code is available on GitHub for developer contributions.
